Voices from the People’s Climate March: Indigenous Groups Lead Historic 400,000-Strong NYC Protest (Democracy Now!)

MONDAY, SEPTEMBER 22, 2014

As many as 400,000 people turned out in New York City on Sunday for the People’s Climate March, the largest environmental protest in history. With a turnout far exceeding expectations, the streets of midtown Manhattan were filled with environmentalists, politicians, musicians, students, farmers, celebrities, nurses and labor activists — all united in their demand for urgent action on climate change. Organizers arranged the People’s Climate March into different contingents reflecting the movement’s diversity, with indigenous groups in the lead. Democracy Now! producers Aaron Maté and Elizabeth Press were in the streets to hear from some of the demonstrators taking part in the historic protest.

This is a rush transcript. Copy may not be in its final form.

AMY GOODMAN: We turn now to the People’s Climate March. Organizers estimate as many as 400,000 people marched in New York Sunday in the largest climate protest in history. The turnout far exceeded expectations. Other marches and rallies were held in 166 countries. More protests are planned for today. Climate activists are gathering today in downtown Manhattan for a mass sit-in dubbed “Flood Wall Street.” The actions are timed to coincide with the United Nations climate summit taking place here in New York Tuesday. President Obama and over 100 other world leaders are scheduled to attend.

Sunday’s events in New York began with an indigenous sunrise ceremony in Central Park. Indigenous activists then led the march.Democracy Now!‘s Aaron Maté was in the streets at the People’s Climate March.

AARON MATÉ: We’re near the very front of the People’s Climate March, and the sign behind me reads: “Front Lines of Crisis, Forefront of Change.” This march has been divided up into different groups, and at the front are indigenous and front-line communities most impacted by climate change.

CLAYTON THOMASMULLER: Hi. My name is Clayton Thomas-Muller. I’m an organizer with the indigenous peoples’ social movement Idle No More and Defenders of the Land. Things today are going really, really well. We’ve got tens of thousands, if not hundreds of thousands, of people on the street. We have front-line indigenous communities from communities that are disproportionately affected by President Obama’s all-of-the-above energy policy. We’ve got leaders from communities fighting fracking, fighting tar sands, pipelines, all kinds of pipeline fighters from across the continent who are organizing in solidarity with First Nations from the belly of the beast in Alberta who are trying to stop tar sands expansion at the source. And we’re here to send a very clear message to President Obama, Stephen Harper and the rest of the world leaders that we need legally binding mechanisms on climate change right now passed, and if they ain’t going to do it, that the people certainly will.

INDIGENOUS ACTIVIST: Hi. We’re here to march for the next seven generations and to take astand against Big Oil companies that are coming through our territories and trying to take our ancestral lands and destroy them. We’re here because it’s going to take all of us—all of us—not just the indigenous people, but everyone in the whole world, to come together to save our water.

PERUVIAN ACTIVIST: We are from the Peruvian delegation here on the March. And we are marching because we are fighting for climate justice, and we are fighting because this December, the next COP event is going to be in our country. And we are preparing a people’s summit and the next march in December 10 in Lima. And we are asking the Peruvian government, Ollanta Humala, for coherence, because even if they are taking pictures here near Ban Ki-moon, they are not doing that kind of commitments in the country. So, we need to fight here, we need to fight in our country. This is a global fight.

EL PUENTE ACTIVIST: Who are we?

EL PUENTE ACTIVISTS: El Puente!

EL PUENTE ACTIVIST: What do we stand for?

EL PUENTE ACTIVISTS: Peace and justice!

FRANCES LUCERNA: My name is Frances Lucerna. I’m the executive director of El Puente. We have about 300-strong here of our young people. We are a human rights organization located in Williamsburg, Brooklyn. Most of our young people are from Puerto Rico, from Dominican Republic. And the connection between what’s happening in terms of our islands and also what’s happening here in our waterfront community that Williamsburg is part of, we need, really, the powers that be to come together with our people and really make decisions that are about preserving our Earth.

CARLOS GARCIA: Hi. My name is Carlos Garcia. I’m the secretary-treasurer of the New York State Public Employees Federation. We represent 54,000 New York state employees who are professional scientific and technical workers. And we’re out here to say to the U.S. government, New York state government, let’s take care of our climate, let’s take care of our environment.

IRENE JOR: My name is Irene Jor. I’m with the National Domestic Workers Alliance with the New York domestic workers here today. And for us, we’re here because, as domestic workers, it’s time to clean up the climate mess.

DOMESTIC WORKERS: We are domestic workers! We want climate justice now!

IRENE JOR: Domestic workers have been part of the struggle for a long time. We’re disproportionately impacted by climate change. For those of us who are migrant women workers, we often come here because of what extractive resources and climate crisis has done to our home countries.

AARON MATÉ: We’ve come upon a huge contingent of young people, many carrying signs reading “Youth choose climate justice.”

YOUTH ACTIVISTS: Obama, we don’t want no climate drama! Hey, Obama, we don’t want no climate drama!

JONAH FELDMAN: My name is Jonah Feldman. I’m here with the Brandeis Divestment Campaign from Brandeis University.

AARON MATÉ: And what does your sign say?

JONAH FELDMAN: It says, “Divest from Climate Change.” We believe that our university should sell off all its investments in the fossil fuel industry—that’s in coal, oil, natural gas, tar sands—and to reinvest into clean, renewable alternatives.

LUIS NAVARRO: Hello. My name Luis Navarro. I’m 16. I’m from Boston, Massachusetts. I’m with the Boston-area Youth Organizing Project. Well, as a youth, I feel like every youth should be a part of this, because it concerns them and their future, whether or not if they can live by 20 years from now with this climate change. And I feel like it’s important for me to be here to show them that the youth is on our side.

AARON MATÉ: As we weave through this march that has taken over midtown Manhattan, tens of thousands out in full force, coming across all different sorts of diverse groups.

VEGAN: Number one way to fight climate change: Go vegan.

REV. SUSAN DE GEORGE: I’m Susan De George, and I’m with both Green Faith and with Hudson River Presbytery. We have everybody from Jains, Sikhs, Buddhists, Hindus, Catholics, Protestants, atheists, agnostics, all marching in a group.

PROTESTERS: What do we want? Climate justice! When do we want it? Now!

CAITLIN CALLAHAN: My name is Caitlin Callahan. I’m from Rockaway Beach, and I’m an organizer with Rockaway Wildfire. Superstorm Sandy devastated the Rockaway Peninsula. We know that climate change is being worsened and exacerbated by all of the systemic profiteering that’s happening throughout our world. And it’s time for that to stop. If you haven’t been involved in climate justice activism before, it’s time to get involved in climate justice activism, because this is affecting all of us.

BRADEN ELLIOTT: My name is Braden Elliott. I’m a Ph.D. student at Dartmouth College, and I’m here because I care.

AARON MATÉ: And the banner under which the scientists are marching is “The Debate is Over”?

BRADEN ELLIOTT: Correct. The banner says “The Debate is Over” because the core part, the part that the planet is warming and that humans are responsible for the lion’s share of it, is settled. There’s always debate to be had on the edges of a large topic, but the call to action is very clear.

AARON MATÉ: And now we’re in the bloc of demonstrators under the banner of “We Know Who is Responsible,” anti-corporate campaigners, peace and justice groups, those who are organizing against the groups they say are holding back progress.

SANDRA NURSE: My name is Sandra Nurse. I’m here with the Flood Wall Street contingent. We’re calling on people to do a mass sit-in in the financial district to highlight the connections between corporate capitalism, extractive industries, the financing and bankrolling of climate change, the financing of politicians who will not bring meaningful legislation to the table and who are blocking the process of actually bringing meaningful legislation against climate change.

FLOOD WALL STREET CONTINGENT: All day, all week, let’s flood Wall Street!

AMY GOODMAN: Some of the voices from the 400,000-strong People’s Climate March here in New York. Special thanks to Aaron Maté and Elizabeth Press in the streets for Democracy Now!

What’s next for climate science beyond the IPCC? (Sci Dev Net)

In lead to December’s 20th UN Conference of Parties on climate change, scientists and policymakers are reflecting on the future of climate science. Many are questioning whether the existing mechanisms that feed scientific evidence into international politics are working well enough.

In this interview Ilan Kelman argues that, despite its important work, the Intergovernmental Panel on Climate Change, with its consensus-based approach, is no longer suited to the new challenges posed by climate change.

The Changing Face of Climate Change (Slate)

Will the leaders of the People’s Climate March now lead the movement?

At the front of the People’s Climate March, moments before the crowd began to move, you could look back and see the wall of stone that makes up the wealthy Upper West Side apartment buildings to your left, and Central Park to your right, in the last of its full-blown green phase before the leaves start to turn. Visible on the street: signs, artwork, and many, many heads.

In the front section of the march, designated by organizers for “the people first and most impacted,” were representatives of the Kichwa from Ecuador, Taino from the Caribbean, Winnemem Wintu from California, and many other indigenous groups in traditional clothing. There were also members of the media and the musician Sting. Young people of color from Brooklyn held large paper sunflowers and an enormous banner reading: “FRONTLINES OF CRISIS, FOREFRONT OF CHANGE.” Above them were the glossy towers that mark the beginning of Midtown and the bright red CNN sign against the fog signaling that the 11:30 a.m. start time was drawing closer. On his spire, Columbus had his back to the crowd.

The march was already the largest climate demonstration in history before the walking began. There was plenty of excitement. But the drums, the chanting, and the drone of conch-shell horns added an air of warfare.

Indigenous and underprivileged communities are already experiencing the worst impact of climate change, and for those at the front of the march, battle-ready would seem an appropriate posture.

Ricken Patel, the founder of the online activist network called Avaaz, told us shortly before the march: “We know that the most vulnerable communities get if first and worst every time.” The refrain was repeated by so many others, and research corroborates it. An analysis from Yale and George Mason University finds that in the United States, climate change is most likely to affect “Hispanics, African Americans, and other racial and ethnic groups who are likely to be more vulnerable to heat waves, extreme weather events, environmental degradation, and subsequent labor market dislocations.”

The people at the front of the march were themselves a sign that the face of mainstream climate activism has shifted from polar bears and Priuses toward marginalized communities. It is, in theory, a shift from what climate researcher Angela Park wrote in 2009 was a movement that “still suffers from the perception, and arguably the reality, that it is … led by and designed for the interests of the white, upper-middle class.”

Seven representatives from frontline communities spoke at a press conference before the march began, including Kathy Jetnil-Kijiner, a 26-year-old writer, professor, and spoken-word artist from the Marshall Islands. She has also been selected by the United Nations from a group of 544 nominees to speak in the opening ceremonies of Tuesday’s Climate Summit.

We caught up with her after the march. Jetnil-Kijiner is small in stature, with long black curly hair, and she appeared exhausted after arriving from the Marshall Islands just the day before the march (not to mention marching and speaking to reporters all day), but she managed to reanimate herself. Walking in Central Park, she told us that she first felt called to climate activism after returning to the Marshall Islands after college in 2010. “There are some parts of the Marshalls where you can stand and see both sides of the ocean,” she said. Rising sea levels, one of the most devastating and permanent consequences of climate change, threaten the very existence of low-lying island nations. In 2008, she woke one morning to find her home island flooded. Houses were destroyed, debris was everywhere, and once the waters receded, the trees shriveled because of the salt.

While people like Jetnil-Kijiner were physically at the front of the march, the question remains whether their voices will be drowned out by the bigger names of climate activism, the Bill McKibbens and the Ricken Patels.

The night before the march, McKibben and other writers and politicians spoke on a panel in the packed Unitarian Church of All Souls on the Upper East Side. Nearing the end of the discussion, the moderator, Brian Lehrer, asked McKibben what was the unified message that he wanted people to take away from the march. Instead of answering, McKibben metaphorically passed the mic, saying, “There will be people from communities who have had to deal with Sandy, the ongoing fact of living in a place where every third kid has an inhaler. They’ll do a good job of speaking powerfully.”

Just before the march, Ananda Lee Tan, an organizer with the Global Alliance for Incinerator Alternatives, told us, “We’re seeing a shift in the movement. This march really marks a flipping of the script.” Tan explained that the communities most impacted by extreme weather have joined together. “We’re taking over the leadership of the U.S. climate movement,” he said, “and so we’ll see on the streets today probably the most diverse, broad, grass-roots climate movement that the U.S. has ever seen.”

The difference is not that communities most threatened by climate change are now involved in the climate change movement. As Jacqueline Patterson, the NAACP’s Environment and Climate Justice Program director, pointed out in a phone interview, frontline communities have been involved in climate justice from the beginning of the movement. What’s new is that a wide range of groups, from labor unions and indigenous tribes to the Granny Peace Brigade, was marching in the same place.

Still, Patterson had a more cautious view of the role of frontline communities in the march and the wider movement. She said that while there was now more acknowledgement that frontline communities needed to be engaged, there was “to a lesser extent, an acknowledgement that the frontline communities need to lead.”

On the Wednesday before the march, a 28-year-old Avaaz canvasser (who preferred to remain anonymous, citing a nondisclosure agreement) echoed Patterson’s concerns. He said there was much improvement in the communication with frontline communities, but he was skeptical of the “big greens” such as Avaaz, 350.org, and the Sierra Club, arguing that they needed to deepen their understanding of organizing in frontline communities. “There’s a lot of wisdom there,” he said. Specifically, he wanted the established environmental organizations to give more money directly to grass-roots organizations. He told us that he planned to quit his canvassing job that evening. He didn’t want to canvas in Washington Square Park anymore; he planned to return to his home community of Staten Island to organize there.

The test of the movement’s potency will, of course, be its coordination beyond the march, its ability to maintain the unity that defined it. And on Tuesday, Kathy Jetnil-Kijiner will have an opportunity to tell world leaders about the Marshall Islands, about what it is like to live on land just two meters above sea level. She is tired of answering the question of where the Marshall Islanders will move when the islands are gone. “We don’t want to move, and we shouldn’t have to move,” she said. “There should be changes now so that doesn’t have to happen.”

Naomi Klein on Cause of Climate Crisis: “Capitalism Is Stupid” (Truthout)

Naomi Klein (Photo: Ed Kashi). Naomi Klein, author of the groundbreaking books, No Logo and The Shock Doctrine, is back with a new groundbreaking work, This Changes Everything: Capitalism vs. The Climate. The book resets the debate over global warming by focusing on how it is integrally related to the current economic system that spans the globe. Contribute to Truthout and receive this vitally important work. Click here now.

Naomi Klein is out to change hearts and minds around climate change.

Her new book, This Changes Everything: Capitalism vs. the Climate out now from Simon & Schuster, is a broad challenge to those who want a livable planet: We need to come up with a livable economic system too. Deeply researched and personally reported, Klein’s third book takes us from the tar sands in Alberta (“Earth, skinned alive”) to the oil-soaked waters of the Gulf of Mexico (“a miscarriage”), from climate denier conferences to a meeting of would-be geoengineers, as she traces the path of destruction that capitalism and a mindset she terms “extractivism” – that is perhaps even older – have left on the Earth.

At one point, Klein concedes, it might have been possible to stop the climate crisis with a few regulations here, a carbon tax there. But we’re too far gone for that, and nothing but a full-on change in how humans relate to the Earth and to each other will save us now.

The good news is that Klein has written an immensely hopeful book, a book about people who believe they can make change and who are doing it in the face of a political and economic system that would seem to doom them to failure. She doesn’t define what comes after capitalism, leaving that to the social movements she describes being born all over the world, but sketches its broad outlines, letting us know what this new climate justice movement is against – but also what it is for – and making a case for a broad redistributive justice movement that would include already-existing movements for racial justice, feminism and decolonization.

The problem is, capitalism is stupid … in that it doesn’t actually think.

Truthout’s Sarah Jaffe caught up with Klein on the eve of the People’s Climate March and of the United Nations Climate Summit in New York to talk about why liberalism is not enough, why billionaires can’t save us, and what we need to do to save ourselves.

Sarah Jaffe for Truthout: You’ve written two other books, No Logo andThe Shock Doctrine, that helped to name and understand a particular historic moment. How was this book a direct outgrowth of your previous work, and how has your worldview changed in the years since those other books?

Naomi Klein: In many ways this is a direct continuation of The Shock Doctrine, in that that book begins and ends with Hurricane Katrina and a glimpse of a future in which our world becomes more and more disaster-prone, with an unstable climate and an unstable economy, and each shock pushes us further apart. It’s the vision of the future that I think we actually take so for granted that we just keep repeating that same vision in every sci-fi apocalyptic movie that gets produced. It’s a small group of winners and hordes of locked-out losers.

The Shock Doctrine was about the worst of humanity in crisis. A lot of people asked me, after it was published, whether or not there could be a progressive response. I remember the first event I did for The Shock Doctrine, before it actually came out, in New Orleans and Saket Soni, a fantastic organizer [with the National Guestworker Alliance and the New Orleans Workers’ Center for Racial Justice], stood up and he said, “OK, they have disaster capitalism, we need disaster collectivism!” I used to quote him all the time. I end that book talking about how there are progressive precedents for crisis being moments of tremendous progressive victory and indeed this is why the right learned how to get in there fast before that could happen, that’s what the Shock Doctrine is.

Going back to No Logo, which was more about tracking the rise of the global production chain, part of what [This Changes Everything] is saying is, we knew that they were combing the world for the cheapest possible labor, and we know the effects of that. I think what was less clear at the time is that there was a direct connection between cheap labor and dirty energy, because if you’re a corporation and all you care about is cutting your production costs, that’s all that matters, it’s going to be cheap, abused labor that doesn’t have the freedom to organize, and it’s going to be coal, the cheapest and dirtiest of the fossil fuels.

So the explosion of the so-called global economy has coincided with an emissions explosion, and why would we be surprised by that, in retrospect? But I think when we were fighting those free-trade deals, a lot of us didn’t understand the climate dimension of that battle. It’s all one long story.

In this book, you say what people just aren’t supposed to say: that fixing the climate is incompatible with capitalism. In particular, you point out the ways that the profit motive has proved corrupting, in some cases to green groups themselves, in other cases to the supposedly beneficent pledges made by the superrich. Can you talk a little bit about how profit hasn’t been able to, and won’t be able to, solve the crisis?

There’s a chapter in the book on why the billionaires won’t save us, and the point of that chapter is not to play gotcha with Michael Bloomberg and Richard Branson. It’s actually to say OK, let’s say that these are the most enlightened billionaires on the planet. And let’s say that they at various points have had the shit scared out of them about climate change. But locked within the imperatives of their model, it’s possible for Michael Bloomberg to simultaneously understand the medium-term risk of fossil fuels and to back reports like “Risky Business” that are all about warnings about the billions of dollars in costs that come with a destabilized climate, and Michael Bloomberg, as an investor, to choose, in a very short-term way, to put his billions in oil and gas, which is what he does.

There was this idea that it was just a process of convincing very wealthy people that this really was a problem, and that there really were costs down the road and that in the long term it would be better to prevent it from happening.

The problem is, capitalism is stupid. You know that cover of Bloomberg Businessweek, “It’s Global Warming, Stupid,” well, it is global warming, but capitalism is stupid in that it doesn’t actually think. It seeks the maximum short-term profit. I think people are mistaking the fact that there are billionaires out there that do get the extent of the problem and really do talk a good game about carbon bubbles and the economic risk, for the idea that that’s going to translate into action. Where that becomes really dangerous is that the UN believes this too. I keep getting press releases from the UN about how the best part of the summit is that it has unprecedented participation from multinationals and CEOs from Bank of America and Walmart and McDonald’s and Amoco. It’s still this same idea that getting people around the table with the right information and the right incentives in place will solve this from the top, and there won’t need to be any friction.

I think the real difference is that now there’s a movement on the outside that says no, that understands that the imperatives for the fossil fuel industry are fundamentally incompatible with a livable climate. That’s the point of the carbon tracker research that kicked off the fossil fuel divestment movement because students look at those numbers and go OK, my university is investing in companies that have made a bet against my future. You can debate fossil fuel divestment as a tactic, but I think that it’s important to understand what you’re up against, and I think there’s much more clarity in the movement now than there has been in decades.

You write about the elite background of the environmental movement, the people who would go hunting with Teddy Roosevelt to convince him to conserve something. Green groups have often seemed to forget the people and focus on saving animals, land, and, as you note in the book, are often taking money from polluters even as they profess to fight them. Do you think these problems are connected?

Yes. I think the environmental movement is not a social movement like we normally think of social movements. It’s not a movement of outsiders, and it never really was, except for the environmental justice movement, which has always from its birth been in a relationship of tension with the green NGOs.

I think it follows seamlessly from those early hunting trips to having BP on your board of directors. The real issue is that at earlier stages of capitalism I think it was easier to reconcile saving a river or saving a mountain with the overall imperatives of expansion and growth, but we’re now at a point where that’s not the case, we need to cut too much and too quickly.

Their model used to be “Sue the Bastards” and it became, . . . “Make Markets for the Bastards.”

The other real turning point, as I say in the book, was what happened in the 1980s. It was Nixon who introduced some of the best top-down environmental regulations. There is a Republican tradition in this country of regulating polluters. But that tradition long ago died. Nobody gets regulated anymore, including polluters. What happened in the ’80s is that it became clear that in order to hang on to that insider status that these green groups needed to change. Some groups decided forget it, we’re going to go on the outside, and there were breakaways and new groups formed that were more militant. And other groups changed with the times.

The Environmental Defense Fund is a really interesting example because they were inspired by Rachel Carson; they are the group that deserves a huge amount of the credit for why DDT was banned. Their model used to be “Sue the Bastards,” and it became, in Eric Pooley’s words, “Make Markets for the Bastards.” That’s the model that continues to this day, and that’s the model that we’re going to see at the UN [this] week.

Large parts of the environmental movement have always been part of the inside game, and when the inside changed, and neoliberalism took over, the movement changed along with it. That left it uniquely ill-equipped to deal with a crisis like climate change. So we wasted a lot of time with carbon trading and carbon offsetting and touting natural gas as a bridge fuel and basically doing anything but getting off fossil fuels.

There’s a growing movement to push foundations and universities to divest from fossil fuels, though critics have argued that this won’t change the behavior of fossil fuel companies. In the book, you argue for the value of this movement and also talk about the move to “reinvest” that money in cleaner technologies. Can you explain why you support the divestment movement and what is happening with reinvestment?

One of the things that has been most pronounced in the resurgence and emergence of these anti-extractive fights, anti-pipeline fights, is that more and more people are coming to the same conclusion, which is that we can’t just say no – we also have to be providing people with real economic alternatives.  We’re just going to be fighting against the worst possible ideas unless we can show people that there’s actually another economic model that will bring them jobs and a better way of life. I hear this again and again, see it again and again: frontline activists going, “We need to build an economic alternative right here.” Communities in England that are fighting fracking have decided to launch their own renewable energy co-ops. First Nations communities in Canada where they’re fighting the Tar Sands are simultaneously launching renewable energy projects because the extractive industries right now are the only ones offering jobs. It’s critical to show that there are these alternatives if we aren’t just going to be scrambling all the time.

I think renewable energy is threatening precisely because it lends itself to decentralization.

The problem is always funding. There’s no shortage of great alternatives out there that are justice-based. In building these alternatives, you’re also strengthening the resistance to fossil fuels. What we’re hearing from frontline communities is that this is what’s most important to embolden communities to fight back. I highlight something like the Black Mesa Water Coalition: They have shut down a coal power plant and are successfully fighting coal, but there’s limits to how much they can win, they say, unless they can show that there’s another way to bring resources to the communities. They have this great proposal to have a utility-scale solar project on Navajo land, land that used to be a coal mine, it’s been decommissioned. It’s a beautiful elegant plan. This is the kind of thing that needs to be funded. And it isn’t being funded by government.

So if we think about the capital that is being moved from fossil fuels right now – and it is being moved: A lot of schools are saying no, but a few have said yes; a lot of cities have said yes; a whole bunch of foundations are now on board. I’m really excited by the prospect of that capital going into investing in a just transition; that can really show how possible and inspiring this transition is.

But we can’t mistake that for the scale of action. We need the scale of action like we’re seeing in Germany, where you have a national feed-in tariff that is shifting that country with incredible speed to renewable energy. In the meantime, until we get there, we also need some really good examples of this working.

There are so many brilliant technologies that do exist to challenge the crisis, you note – just this week we heard that Burlington, Vermont is now getting all of its power from renewable sources. Yet the people who propose to save the earth with technology are more interested in terrifying types of geoengineering. Why do you think solar energy isn’t exciting enough for them?

I think renewable energy is threatening precisely because it lends itself to decentralization. It’s not that money can’t be made, but it lends itself to more people making less money. Some people have talked about fossil fuels as technologies of the 1%, or the 1% of the 1%, because as soon as you have an extractive-based technology – I’d include nuclear in that – the resource itself is concentrated in specific locations; it’s not available everywhere; it takes a lot of money to get it out; it takes a lot of money to refine it; it takes a lot of money to transport it. That means you’re only going to have a few big players who are going to profit a lot.

What we can have is more deliberate growth and that does mean valuing work that we currently don’t value at all.

So it’s not that you can’t have all kinds of economic opportunities in a renewables-based economy. But it is going to be a more level economy because you have so many players. That’s what’s worked best in Germany, the multiplication of these small-scale projects. You’ve got some big projects as well, but you have 900 new energy co-ops, hundreds of municipal-scale renewable energy utilities popping up. It’s not about whether you can make money off this. It’s about whether a few people are going to continue to make the kind of stupid money that is actually the barrier to progress. I think the answer is no, and that’s why they’re fighting tooth and nail to protect that model and are willing to entertain dimming the sun and fertilizing the seas before they entertain putting up solar panels on a mass scale.

Your subtitle is Capitalism vs. the Climate, but you actually go beyond capitalism and challenge the whole mindset of what you call “extractivism.” I kept finding myself thinking, at various times, that the book was also about “patriarchy vs. the climate” and “colonialism vs. the climate.” There’s a theme that runs through the book where you talk about the need to revalue caring work, women’s reproductive labor, even mention the Wages for Housework movement. I would love to hear you talk about what kind of work we need to value, what kinds of values we need to have in order to create a new system beyond capitalism.

It’s a great question. It is beyond – that’s why I talk about extractivism as a mindset. Some people talk about it as instrumentalism, which is really just about “I’m going to take from you and get whatever I can out of you.” That’s how we relate to each other, and that’s how we relate to the earth. It’s not a reciprocal relationship, it isn’t a regenerative relationship. We need to get at the core of how we got here in the first place, which was this mentality of this intense hierarchy between people who supposedly mattered and people who didn’t matter, places that supposedly mattered and places that didn’t matter and could therefore be sacrificed.

It is important to understand the clash between the kind of economic growth that we have and the constraints presented to us by atmospheric science. We can’t just keep growing our economy. But that said, there are low-carbon parts of our economy that we want to expand and can expand. What we can’t have is stupid growth in the same way that we can’t have stupid profits. What we can have is more deliberate growth, and that does mean valuing work that we currently don’t value at all.

When we do that work of valuing work that is now being belittled and mistreated, what we start doing is creating more economic options for people and for communities, and that in turn makes it less likely for people to make those impossible decisions that so many communities are being asked to make right now; whether to have water or whether to have a mine; or whether to have a refinery in their backyard.

That’s why I talk about basic income as well, that there has to be a stronger social safety net because when people don’t have options, they’re going to make bad choices. Let’s have better choices on the table.

You write about the hope that has come since you started work on this book, the new movements, the new attention. What more hopeful signs have you seen since you finished the book?

I’m excited about the energy of this moment where I see a lot of people engaging in climate change that I know weren’t engaged just a year ago. It’s really exciting to see a lot of people who were involved in Occupy Wall Street getting involved in Flood Wall Street. I think those connections are being made really fast by some really smart people who’ve already shown that they can change the debate.

Having spent a few weeks talking mostly to journalists about the book, a lot of mainstream journalists outside of the US, I think that the moment we’re in is essentially about whether or not we believe in social movements. It’s really striking to me. If somebody, a progressive person who has experience with social movements and believes in social movements reads the book, they tell me that they feel inspired and hopeful and excited. But a lot of the liberal journalists who I’ve been speaking to tell me that they read the book, and it just fills them with despair because they don’t believe in activism. I expected to be having arguments about the science; I expected to be having arguments about the policy: I’ve had basically none of those. I’m having arguments about whether or not there’s a reason to have any hope at all. That’s a hard thing to do all day!

I think there’s something about climate change – I’m realizing this more and more since finishing the book – that really demarcates the difference between liberals and radicals, liberals and leftists in the sense that if you are really committed to that sort of reasonable centrist reformist model, top-down model of change, and you also are willing to look at the science and look at the, be honest about the kind of economy we’re in, then you’re filled with despair. Look at Ezra Klein writing “7 reasons America will fail on climate change.” If you believe that the only way the world changes is through a combination of policy wonks and enlightened leaders, then you will be in despair because you will look at the aligned, entrenched interests in a dysfunctional democracy, and you will say “we’re cooked.”

If, however, you believe that social movements have grabbed the wheel of history before and might just do it again, if you’ve caught glimpses of that in your life, the moments when suddenly it seems that everything’s changing, then you still hold out that hope.

I’m looking forward to being around activists for a few days!

Indian scientists significantly more religious than UK scientists (Science Daily)

Summary: Indian scientists are significantly more religious than United Kingdom scientists, according to the first cross-national study of religion and spirituality among scientists.


Indian scientists are significantly more religious than United Kingdom scientists, according to the first cross-national study of religion and spirituality among scientists.

The U.K. and India results from Religion Among Scientists in International Context (RASIC) study were presented at the Policies and Perspectives: Implications From the Religion Among Scientists in International Context Study conference held today in London. Rice’s Religion and Public Life Program and Baker Institute for Public Policy sponsored the conference. The U.K. results were also presented at the Uses and Abuses of Biology conference Sept. 22 at Cambridge University’s Faraday Institute in Cambridge, England.

The surveys and in-depth interviews with scientists revealed that while 65 percent of U.K. scientists identify as nonreligious, only 6 percent of Indian scientists identify as nonreligious. In addition, while only 12 percent of scientists in the U.K. attend religious services on a regular basis — once a month or more — 32 percent of scientists in India do.

Elaine Howard Ecklund, Rice’s Autrey Professor of Sociology and the study’s principal investigator, said the U.K. and India data are being released simultaneously because of the history between the U.K. and India. She noted that their differences are quite interesting to compare.

“India and the U.K. are at the same time deeply intertwined historically while deeply different religiously,” Ecklund said. “There is a vastly different character of religion among scientists in the U.K. than in India — potentially overturning the view that scientists are universal carriers of secularization.”

Despite the number of U.K. scientists identifying themselves as nonreligious, 49 percent of U.K. survey respondents acknowledged that there are basic truths in many religions. In addition, 11 percent of U.K. survey respondents said they do believe in God without any doubt, and another 8 percent said they believe in a higher power of some kind.

Ecklund noted that although the U.K. is known for its secularism, scientists in particular are significantly more likely to identify as not belonging to a religion than members of the general population.

“According to available data, only 50 percent of the general U.K. population responded that they did not belong to a religion, compared with 65 percent of U.K. scientists in the survey,” Ecklund said. “In addition, 47 percent of the U.K. population report never attending religious services compared with 68 percent of scientists.”

According to the India survey, 73 percent of scientists responded that there are basic truths in many religions, 27 percent said they believe in God and 38 percent expressed belief in a higher power of some kind. However, while only 4 percent of the general Indian population said they never attend religious services, 19 percent of Indian scientists said they never attend.

“Despite the high level of religiosity evident among Indian scientists when it comes to religious affiliation, we can see here that when we look at religious practices, Indian scientists are significantly more likely than the Indian general population to never participate in a religious service or ritual, even at home,” Ecklund said.

Although there appear to be striking differences in the religious views of U.K. and Indian scientists, less than half of both groups (38 percent of U.K. scientists and 18 percent of Indian scientists) perceived conflict between religion and science.

“When we interviewed Indian scientists in their offices and laboratories, many quickly made it clear that there is no reason for religion and science to be in conflict; for some Indian scientists, religious beliefs actually lead to a deeper sense of doing justice through their work as scientists,” Ecklund said. “And even many U.K. scientists who are themselves not personally religious still do not think there needs to be a conflict between religion and science.”

The U.K. survey included 1,581 scientists, representing a 50 percent response rate. The India survey included 1,763 scientists from 159 universities and/or research institutions. Both surveys also utilized population data from the World Values Survey to make comparisons with the general public. In addition, the researchers conducted nearly 200 in-depth interviews with U.K. and Indian scientists, many of these in person.

The complete study will include a survey of 22,000 biologists and physicists at different points in their careers at top universities and research institutes in the U.S., U.K., Turkey, Italy, France, India, Hong Kong and Taiwan — nations that have very different approaches to the relationship between religious and state institutions, different levels of religiosity and different levels of scientific infrastructure. Respondents were randomly selected from a sampling frame of nearly 50,000 scientists and compiled by undergraduate and graduate students at Rice University through an innovative sampling process. The study will also include qualitative interviews with 700 scientists. The entire RASIC study will be completed by the end of 2015.

Bacterial ‘communication system’ could be used to stop, kill cancer cells, study finds (Science Daily)

Date: September 24, 2014

Summary: A molecule used as a communication system by bacteria can be manipulated to prevent cancer cells from spreading, a study has demonstrated. “During an infection, bacteria release molecules which allow them to ‘talk’ to each other,” said the lead author of the study. “Depending on the type of molecule released, the signal will tell other bacteria to multiply, escape the immune system or even stop spreading.”

Cancer, while always dangerous, truly becomes life-threatening when cancer cells begin to spread to different areas throughout the body. Now, researchers at the University of Missouri have discovered that a molecule used as a communication system by bacteria can be manipulated to prevent cancer cells from spreading. Senthil Kumar, an assistant research professor and assistant director of the Comparative Oncology and Epigenetics Laboratory at the MU College of Veterinary Medicine, says this communication system can be used to “tell” cancer cells how to act, or even to die on command.

“During an infection, bacteria release molecules which allow them to ‘talk’ to each other,” said Kumar, the lead author of the study. “Depending on the type of molecule released, the signal will tell other bacteria to multiply, escape the immune system or even stop spreading. We found that if we introduce the ‘stop spreading’ bacteria molecule to cancer cells, those cells will not only stop spreading; they will begin to die as well.”

In the study published in PLOS ONE, Kumar, and co-author Jeffrey Bryan, an associate professor in the MU College of Veterinary Medicine, treated human pancreatic cancer cells grown in culture with bacterial communication molecules, known as ODDHSL. After the treatment, the pancreatic cancer cells stopped multiplying, failed to migrate and began to die.

“We used pancreatic cancer cells, because those are the most robust, aggressive and hard-to-kill cancer cells that can occur in the human body,” Kumar said. “To show that this molecule can not only stop the cancer cells from spreading, but actually cause them to die, is very exciting. Because this treatment shows promise in such an aggressive cancer like pancreatic cancer, we believe it could be used on other types of cancer cells and our lab is in the process of testing this treatment in other types of cancer.”

Kumar says the next step in his research is to find a more efficient way to introduce the molecules to the cancer cells before animal and human testing can take place.

“Our biggest challenge right now is to find a way to introduce these molecules in an effective way,” Kumar said. “At this time, we only are able to treat cancer cells with this molecule in a laboratory setting. We are now working on a better method which will allow us to treat animals with cancer to see if this therapy is truly effective. The early-stage results of this research are promising. If additional studies, including animal studies, are successful then the next step would be translating this application into clinics.”

Liberia: Dead Ebola Patients Resurrect? (The New Dawn)

24 SEPTEMBER 2014

By Franklin Doloquee

Two Ebola patients, who died of the virus in separate communities in Nimba County have reportedly resurrected in the county. The victims, both females, believed to be in their 60s and 40s respectively, died of the Ebola virus recently in Hope Village Community and the Catholic Community in Ganta, Nimba.

But to the amazement of residents and onlookers on Monday, the deceased reportedly regained life in total disbelief. The New Dawn Nimba County correspondent said the late Dorris Quoi of Hope Village Community and the second victim only identified as Ma Kebeh, said to be in her late 60s, were about to be taken for burial when they resurrected.

Ma Kebeh had reportedly been in door for two nights without food and medication before her alleged death. Nimba County has had bizarre news of Ebola cases with a native doctor from the county, who claimed that he could cure infected victims, dying of the virus himself last week.

News of the resurrection of the two victims has reportedly created panic in residents of Hope Village Community and Ganta at large, with some citizens describing Dorris Quoi as a ghost, who shouldn’t live among them. Since the Ebola outbreak in Nimba County, this is the first incident of dead victims resurrecting.

Heirs to Rockefeller oil fortune divest from fossil fuels over climate change (The Guardian)

Heirs to Standard Oil fortune join campaign that will withdraw a total of $50bn from fossil fuels, including from tar sands funds

US will not commit to climate change aid for poor nations

Rockefeller, and Stephen B Heintz, president of the Rockefeller Brothers Fund. Photograph: Brendan McDermid/Reuters

The heirs to the fabled Rockefeller oil fortune withdrew their funds from fossil fuel investments on Monday, lending a symbolic boost to a $50bn divestment campaign ahead of a United Nations summit on climate change.

The former vice-president, Al Gore, will present the divestment commitments to world leaders, making the case that investments in oil and coal have an uncertain future.

With Monday’s announcement, more than 800 global investors – including foundations such as the Rockefeller Brothers, religious groups, healthcare organisations, cities and universities – have pledged to withdraw a total of $50bn from fossil fuel investments over the next five years.

The Rockefeller Brothers Fund controls about $860m in assets, said Beth Dorsey, the chief executive of the Wallace Global Fund and the Divest-Invest movement, which has led the divestment campaign. About 7% are invested in fossil fuels.

But the Rockefellers’ decision to cut their ties with oil lends the divestment campaign huge symbolic importance because of their family history. The divestment move also helps bring a campaign launched by scrappy activists on college campuses into the financial mainstream.

But for oil, there may not have been a Rockefeller fortune. John and William Rockefeller were the co-founders of the Standard Oil Company, which at the time operated the world’s biggest refineries, and overtime spawned Exxon, Amoco and Chevron.

Now, after a year of deliberations, the descendants of those original Rockefellers had decided the time had come to move away from oil.

“John D Rockefeller, the founder of Standard Oil, moved America out of whale oil and into petroleum,” Stephen Heintz, president of the Rockefeller Brothers Fund, said in a statement. “We are quite convinced that if he were alive today, as an astute businessman looking out to the future, he would be moving out of fossil fuels and investing in clean, renewable energy.”

In addition to the Rockefellers, the World Council of Churches, which represents some 590 million people in 150 countries – also pulled its investments from fossil fuels on Monday. The move represented a turning point for a movement which began by demanding that universities purge their financial holdings of ties to the fossil fuel industry.

About 30 cities have also chosen to divest, including Santa Monica and Seattle.

“When you have the Rockefellers and the World Council of Churches and institutions with global reach coming together and divesting, then this movement which began just three short years ago has really reached a significant turning point,” Dorsey said.

In that time, supporters such as Archbishop Desmond Tutu have framed divestment from fossil fuels as a moral imperative – like the anti-apartheid movement of a generation ago.

“Climate change is the human rights challenge of our time. We can no longer continue feeding our addiction to fossil fuels as if there is no tomorrow, for there will be no tomorrow,” Tutu said in a video address.

The Rockefeller Brothers Fund over the years has been a big supporter of environmental causes, including to campaign groups opposed to fracking and the Keystone XL pipeline, which made for an awkward fit at times with its continued investment in oil and gas. The family plans to first divest from tar sands commitments.

A number of universities have also started to cut their ties with fossil fuel – with Stanford University dropping coal holdings from its $18bn endowment.

But divestment remains a hard sell. The University of California system said last week it would continue to hold on to fossil fuels. Harvard University has also resisted pressure from faculty and students to divest – although Yale has said it will look into whether renewable energy offers a better bet in the long run.

“In the last great divestment campaign, Harvard said no before it said yes. I think it’s just a matter of time,” Dorsey said. “Unlike with the anti-apartheid movement, this is not just an ethical issue. There is a powerful financial reason as well.”

Jon Stewart Obliterates Republicans By Highlighting Their Ignorance On Climate Change (Politicus USA)

Tuesday, September, 23rd, 2014, 10:09 am

jon stewart climate changeedited

On Monday night’s episode of The Daily Show with Jon Stewart, host Jon Stewart devoted the first segment of his program to the subject of climate change. He discussed the People’s Climate March that took place in New York City on Sunday,where over 100,000 people took to the streets to bring awareness to the dangers facing our planet due to rapid global warming. Stewart pointed out that, while you would think people around the world are now acutely aware of the existence of climate change and its effects on the environment, this march was necessary because House Republicans continue to deny its existence.

The Daily Show host then directed his attention to a recent hearing by the House Committee on Science, Space and Technology, where White House Science Director, John Holdren,spoke in front of the committee to discuss President Obama’s initiative to reduce carbon emissions 30% by the year 2030. Stewart lamented that Holdren had the unenviable task of “pushing a million pounds of idiot up a mountain.”

Below is video of the entire segment, courtesy of Comedy Central.

Stewart highlighted the various Republicans on the committee who peppered Holdren with idiotic questions or flat-out conspiracy theories. Confirmed moron Steve Stockman asked Holdren about global ‘wobbling.’ Stockman wanted to know why it wasn’t included in any climate models when he had read somewhere that it helped contribute to the last major ice age. Holdren patiently pointed out to Stockman that ‘wobbling’ refers to changes in the planet’s tilt and orbit and takes place over tens of thousands of years. It is very slow and has a tiny effect within a time scale of 100 years, which is the normal time frame for climate models.

Of course, the stupid wasn’t just contained to Stockman. A clip was played showing California Congressman Dana Rohrabacher, a well-known climate skeptic, tossing out a question about the dangers of carbon dioxide Rohrabacher wanted to know at what level does carbon dioxide become dangerous for human beings. When Holdren stated that he always enjoys his interactions with Rohrabacher, Stewart interjected, claiming Holdren meant it in the same way someone enjoys playing peek-a-boo with a baby or teasing a cat with a laser pointer. Stewart then showed Holdren’s response, where Holdren told Rohrabacher that his question was a red herring. As Holdren stated, the focus on CO2 is not about whether or not humans can breathe with increased levels, but if those increased levels trap heat in the atmosphere and rapidly change global temperatures.

However, the worst may have been Indiana Representative Larry Bucshon. The Congressman revealed himself as a full-fledged denier on the tin-foil hat variety during the hearing. He wondered why Holdren wasn’t listening to public comments on global warming. Holdren answered that perhaps Bucshon should read the scientific literature available on the subject instead of public opinion. As exasperated Stewart stated that Bucshon should read a climate science journal instead a teabaggers YouTube comments. Stewart then said Bucshon gave away the game when Bucshon told Holdren that he doesn’t believe scientists because it is their job to do these studies. In his opinion, scientists have a vested interest to create a hoax and therefore he won’t read what they produce.

After pointing out Bucshon’s idiocy, while also revealing that Bucshon’s biggest campaign donors are energy companies, Stewart then turned it back to Stockman to end the segment. He showed Stockman asking about the rise of sea levels and wondering how long it will take. Then, Stockman amazingly insisted that sea levels won’t rise because of displacement, using an example of melting ice cubes in a glass. This finally set Stewart off. Stewart tore apart Stockman’s lack of understanding of grade-school science by bringing out a glass of ice water and a bowl of ice. Stewart then proved the point that displacement only takes into account ice that is already in a body of water. However, if you take ice from elsewhere, say land, and put it in a body of water, that water level will rise.

All in all, this was one of Stewart’s best segments in a while. He tore apart the willful ignorance and Koch-funded denial of the Republican Party when it comes to the issue of climate change. The fact is, Republicans are placing us in great harm by refusing to act at all when it comes to global warming and the devastating effects it is having on our country and planet.

Cacique é impedido pelo governo federal de participar da 1ª Conferência Mundial sobre os Povos Indígenas (IHU)

Ban Ki-Moon, secretário-geral da Organização das Nações Unidas (ONU), prometeu na manhã desta segunda-feira, 22, lutar contra a exclusão e a marginalização a que povos indígenas estão submetidos no mundo. A declaração acontece a propósito da abertura da 1ª Conferência Mundial sobre os Povos Indígenas, na sede das nações Unidas, em Nova York. A fala do secretário-geral da ONU, neste momento histórico, ocorre na ocasião em que pela segunda vez no ano uma liderança indígena é impedida de sair do país pelo governo brasileiro.

A reportagem é do portal do Conselho Indigenista Missionário – Cimi, 22-09-2014.

O cacique Marcos Xukuru recebeu o aviso da Funai, na última sexta-feira, 19, de que não poderia embarcar para Nova York e participar da conferência devido ao fato de ter pendência com a Justiça brasileira. O cacique integraria a delegação indígena do Brasil. A pendência, na verdade, trata-se de um processo judicial envolvendo a luta pela demarcação da Terra Indígena Xukuru do Ororubá, no município de Pesqueira (PE), em 2003, que já transitou e foi julgado pelo Tribunal Regional Federal da 5ª Região (TRF-5).

“Não há nenhum impedimento judicial dizendo que eu não posso sair do país. Recentemente tive duas vezes no exterior para fazer denúncias de violações aos direitos humanos contra os povos indígenas. Uma delas em Nova York, inclusive. Houve um boicote que partiu do Ministério da Justiça. Sabemos que existe receio por parte de gente do governo quanto ao que podemos dizer para o mundo”, afirma o cacique. A Assessoria Jurídica do Conselho Indigenista Missionário (Cimi) diz não ter conhecimento de nenhum outro processo envolvendo o cacique fora esse já encerrado.

A presidente da Funai, Maria Augusta Assirati, conforme Marcos Xukuru, fez o convite para que ele participasse da conferência. Foi ela também que justificou as razões do impedimento ao cacique, numa ligação onde Maria Augustadisse que a suspensão da viagem se deu por questões diplomáticas, em face da pendência judicial. “A Funai me convidou para ir com outras lideranças. Um processo que não me proíbe de viajar foi usado. É uma situação. Sabemos que isso veio do Ministério da Justiça”, diz o Xukuru. O cacique, por medida cautelar da Organização dos Estados Americanos (OEA), faz parte do programa de proteção do estado de Pernambuco.

O demais integrantes da delegação do Brasil que se deslocou para Nova York ameaçou boicotar o encontro caso o cacique não fosse reintegrado ao grupo. Porém, o Xukuru explica que pediu aos parentes que demovessem a ideia e fossem à conferência, alegando que “é um momento único para dizer o que se passa no país, quais violações estão acontecendo aqui e que lideranças estão sendo impedidas de dialogar em âmbito mundial justamente pela criminalização que sofrem quando lutam por seus direitos”, ataca o cacique Marcos Xukuru.

Este ano já é o segundo caso de lideranças indígena impedida de viajar ao exterior para agendas políticas, de denúncia de violações aos diretos destes povos. Em abril, o cacique Babau Tupinambá, uma das lideranças da luta pela demarcação da Terra Indígena Tupinambá de Olivença, no sul da Bahia, foi barrado a ir ao Vaticano para encontro com o Papa Francisco, a convite da Conferência Nacional dos Bispos do Brasil (CNBB). Depois de conceder o visto, a Polícia Federal voltou atrás alegando que existiam ordens de prisão contra Babau e pediu que ele devolvesse o passaporte apresentando-se à autoridade policial.

A 1ª Conferência Mundial sobre os Povos Indígenas termina nesta terça, 23. Um documento sobre os direitos dos povos indígenas e sua implementação, preparado diante de consulta aos países integrantes da ONU e povos indígenas, deverá concluir o histórico encontro mundial. Segundo a ONU, existem 370 milhões de indígenas de mais de 5 mil comunidades espalhados por 90 países. Eles representam 5% da população global. No Brasil, são quase 900 mil indígenas divididos em 305 povos. O país também concentra cerca de 94 grupos livres, ou seja, povos em situação voluntária de isolamento.

Processo contra o cacique do povo Xukuru

Cacique Marcos Xukuru, em 2003, sofreu um atentado em um trecho da estrada que corta a Terra Indígena Xukuru do Ororubá. Na ocasião, dois jovens indígenas acabaram mortos e um terceiro conseguiu fugir, avisando as demais lideranças do povo. Com dois mortos e o cacique desaparecido – ele havia corrido para o interior da mata – a comunidade, tomada por uma comoção coletiva, incendiou a sede da fazenda localizada onde o atentado ocorreu e se dirigiu para a Vila de Cimbres com o objetivo de retirar da terra indígena o que restava de invasores e aliados dos fazendeiros.

O conflito entre os xukuru e os invasores foi inevitável. A terra indígena, naquele momento, já tinha sido demarcada. No entanto, o cacique, então vítima de um atentado, passou a ser acusado de ter liderado os ataques contra os fazendeiros e demais invasores do território. Um processo de desenrolou por quase 10 anos, até que o TRF-5 o julgou condenando cacique Marcos e mais 20 lideranças do povo Xukuru a quatro anos de prisão. A sentença, no entanto, foi revertida em pena alternativa com o pagamento de cestas básicas.

No dia 3 deste mês, a Assembleia Legislativa de Pernambuco condecorou o cacique Marcos Xukuru com a comenda Leão do Norte, na categoria Direitos Humanos.

On the Cusp of Climate Change (New York Times)

U.S. Fish and Wildlife Service, via Associated Press

Walruses

Sea ice is critical for all parts of the walrus’s life cycle. Adults dive and eat on these frigid platforms, and females give birth and raise their pups there. But as sea ice retreats during Arctic summers, walruses are being driven ashore.

“In the summer we’ve seen the sea ice recede far to the north,” said Chadwick V. Jay, a research ecologist for the United States Geological Survey. That change is “making it very difficult for walruses to make a living.”

In five of the last seven summers, tens of thousands of female Pacific walruses and their pups have come ashore in Alaska, farther from their preferred prey: the clam, worm and snail beds in the deep waters of the Bering and Chukchi Seas.

An Animal Gamble in the Arctic (8:59) – The Arctic is changing — fast. Two experts who have spent decades working there believe that the marine mammals who call the high latitudes home are now locked into a human-forced ecological game of chance.

Tea

In China, the tea harvest depends on the monsoons: The best tea is harvested in springtime, when the weather is still dry. But climate change threatens to extend the monsoon season.

“Post monsoon season, farmers get much less from their harvest, and a lot of the chemicals that give tea its flavor drop,” said Colin M. Orians, a chemical ecologist at Tufts University. “If climate changes the onset of the monsoon season, farmers will have a shorter window in which to harvest their tea.”

Over the next four years, Dr. Orians and his team will investigate the effects of changing temperatures and rainfall on tea quality and on the livelihoods of farmers who depend on the harvest.

Salamanders

Salamanders in the Appalachian Mountains are getting smaller, and species at lower altitudes, where the greatest drying and warming has occurred, are the most affected. One species became 18 percent smaller over 55 years.

“It could be that a change in body size is the first response to climate change,” said Karen Lips, an ecologist at the University of Maryland. “Their food may be affected, and they may be producing smaller babies.”

Dr. Lips partially relied on the data of Richard Highton, a retired ecologist from the University of Maryland who spent 50 years studying and collecting salamanders that are now preserved at the Smithsonian Institution. At the time of his retirement, he noted that salamanders were mysteriously disappearing.

“If they are not nearly as big, they may not be producing as many offspring,” Dr. Lips said.

To test the theory, Dr. Lips and her team plan to raise salamanders in incubators that mimic different climates.

Bumblebees

Bumblebees and other pollinators are critical to global agriculture, but recent studies suggest that up to one-quarter of Europe’s bumblebee population may die out.

Researchers say that climate change is at least partly to blame, along with disease and loss of habitat.

Scientists estimate that pollinators indirectly contribute about $30 billion a year to the European economy.  “Pollinators are essential to our population,” said Jean-Christophe Vié, deputy director of the species program at the International Union for Conservation of Nature in Switzerland.

Roe Deer

Roe deer, a small, reddish-brown species that flourishes all over Europe, give birth when new plant growth provides ample nutritious food for the mother. But flowers are blooming earlier than they used to, and the deer are missing their meals.

Researchers tracked deer births from 1985 to 2011 in the Champagne region of northeastern France, where average spring temperatures have steadily increased and flowering time is coming gradually earlier. The study is online in PLOS Biology.

The deer time their fertility by light availability, not temperature. With earlier springs, they are now giving birth too late to take advantage of the best food.

Using data on 1,095 births, the scientists calculated that the mismatch between flowering time and birth over the period had grown by 36 days.

The researchers estimate that deer fitness declined by 6 percent over the period, and by 14 percent in 2007 and 2011, when flowering was particularly early.

“Roe deer are very dependent on large quantities of high quality food, and the critical stage is the first week’s supply,” said the lead author, Jean-Michel Gaillard, a director of research at the National Center for Scientific Research at the University of Lyon. “Unlike birds, for example, that can migrate and breed earlier, roe deer cannot.”

Olives

In the Mediterranean Basin, small olive farms can support entire families. Olive trees are notoriously drought-resistant, and even in arid ecosystems they attract migratory birds and a host of insect species.

But as the region warms, some olive trees will not be as productive.

“In the south, you’re going to see a lower crop yield,” said Andrew Paul Gutierrez, an ecologist at the University of California, Berkeley. “In marginal areas, the farmers will just go out of business.”

Dr. Gutierrez and his colleagues predict that some local farmers ultimately will have to abandon their orchards, leaving barren swaths of desert where biodiversity once flourished.

Lemmings

Contrary to myth, lemmings do not commit mass suicide. But populations do rise and fall in predictable cycles, to the benefit and detriment of predators like arctic foxes and migratory birds.

Recently, scientists noticed that some groups of lemmings have died off.

“The lemming cycle is the heartbeat of the terrestrial Arctic,” said Nicolas Lecomte, a biologist at the University of Moncton in Canada. “Now we’re seeing the collapse of the main prey of many terrestrial predators.”

Lemmings survive harsh winters by hiding in the snow. When warmer temperatures bring off-season rain, that snow turns to ice, and the lemmings cannot burrow.

Dr. Lecomte has found that as lemmings die off en masse, the fragile Arctic ecosystem is growing weaker.

Wheat, Rice and Corn

If wheat, rice and corn are going to continue to feed the world, the crops will have to adapt to warmer temperatures. The latest report from the Intergovernmental Panel on Climate Change offers some predictions.

The analysis, published last spring in Nature Climate Change, concluded that a 3.6 degree Fahrenheit increase in temperature will bring a significant decline in crop yields.

Most projections see a decrease from 2030 onward, with greater decreases in the 2040s and 2050s.

Selective breeding and changes in irrigation methods, pest control, fertilization and planting dates may compensate, partially, for the temperature change. But most of these adaptations will work better in temperate regions, while tropical crop yields will continue to decline.

Extreme weather events — another consequence of climate change — will affect yields year-to-year in ways that are difficult to forecast.

“There are two pieces of bad news here,” said the lead author of the I.P.C.C report, Andy J. Challinor, a professor of climate impact at the University of Leeds in England. “One is that average yields are going down. The other is that yields in any given year will be less reliable.”

Sharks

Sharks pursue their prey partly by odor, but rising carbon dioxide levels may severely impair their sense of smell.

Scientists used the smooth dogfish, a small shark, as an experimental animal. They created tanks in which some jets of water held the odor of squid, a favorite food, or no odor at all. The water in the tanks also contained varying levels of carbon dioxide.

With carbon dioxide levels resembling today’s, the sharks spent 60 percent of their time nosing about the plume with the squid odor. But in water with carbon dioxide concentrations predicted for the year 2100, the animals actively avoided the jet with the food odor, spending only 15 percent of their time there.

Any change in shark feeding habits might affect other species as well.

“There might be a decrease in hunting behavior among sharks, and an increase in prey animals as a result,” said a co-author, Ashley R. Jennings, a researcher at Boston University. “That’s assuming the prey animals aren’t being affected by CO₂ as well.”

Conch Snails

As the oceans gather carbon, a small sea snail that lives in the Great Barrier Reef risks losing its famous ability to leap.

The conch snail jumps to escape from a predator, also a sea snail, that tries to inject it with a poisonous dart.

In laboratory experiments in water with increased carbon dioxide levels, the snails were 50 percent less likely to jump. And snails that did jump took nearly twice as long to do so.

The carbon dioxide and acidity disrupt a neurotransmitter receptor in the snail’s nervous system, one that other marine animals also rely on.

“They are very widespread,” said Sue-Ann Watson, a biologist at James Cook University in Australia. “It could affect many marine animals and their behaviors.”

Oceans today are 30 percent more acidic than they were 250 years ago, when the Industrial Revolution started. And it is getting worse.

“By the end of the century, if we carry on with business as usual, they will be 150 percent more acidic than they were 250 years ago,” Dr. Watson said.

Moss

As Arctic temperatures rise every summer, some of the ice on Canada’s Baffin Island melts, revealing the moss trapped underneath. Now, using radiocarbon dating, researchers have determined that until recently some of that moss hadn’t seen daylight in 44,000 years.

The melting ice not only gives scientists the chance to study ancient moss, but adds to evidence that climate change is caused by human activities, not Earth’s natural warming and cooling cycle, said Gifford H. Miller, a geologist at the University of Colorado.

“Cyclical warming is mostly related to the Earth’s irregular orbit around the sun,” he said. The Earth warms when it’s nearer the sun and cools when it’s farther away.

“For the past 10,000 years, we’ve been getting farther away,” he said. The exposure of such ancient moss suggests “the Arctic is now experiencing warmer summers than at any time since the end of the Ice Age.”

Chickadees

Black-capped chickadees are commonly found in the Northeastern United States. Carolina chickadees make their home in the Southeast. Between them is a narrow zone in which both breeds reproduce in the spring.

As winter temperatures have risen over the past decade, the birds’ social scene has moved steadily northward. Today, it is about seven miles farther north than it was in 2004.

The reason? Carolina chickadees are trying to move north — like many other species dealing with climate change — and are running into the black-caps.

“As they start interacting with the black-caps, they try to hybridize,” said Robert L. Curry, a biologist at Villanova University who has studied the birds. But a high percentage of the hybrid eggs don’t hatch, he has found, and hybrid chickadees are probably less fertile.

This is unfortunate for both species in the short term, but it would be even worse for two species not accustomed to mixing.

“This is a model for what could happen if you had an introduced species moving into a new area because of climate change, then come in contact with a species it’s never met before,” Dr. Curry said.

Wildflowers

To everything there is a season — including, of course, the flowering of plants. But a warming climate is changing the timing in complicated ways.

Scientists reviewed 39 years of records of flowering plants in the Rocky Mountains in Colorado, a period in which each decade saw a 0.72 degree Fahrenheit increase in average summer temperatures and a 3.5-day earlier spring snow melt.

The resulting study, published in Proceedings of the National Academy of Sciences last spring, found considerable variation in the changes in flowering, and a much larger number of species affected than previously believed.

Some form of flowering change occurred in 41 of 60 species examined. On average, first flowering advanced by 3.3 days per decade, peak flowering by 2.5 days, and final flowering by 1.5 days.

“The changes in the flower community are potentially reshuffling what’s available for the pollinators,” said a co-author, Amy M. Iler, a postdoctoral researcher at the Rocky Mountain Biological Laboratory. “We don’t know what all the consequences will be. It’s likely it will be good for some and bad for others.”

Dr. Andrew Weeks

Fruit Flies

As temperatures rise, insect populations may relocate around the globe in search of more hospitable environments. But it is the extreme highs, not just the average rise in temperatures, that may determine where they end up.

Scientists studied 10 different fruit fly species in Australia (both temperate and tropical), noting the temperature ranges each preferred for mating and everyday life, and their thresholds for extreme hot and cold.

All the species lived in environments where temperatures were sometimes less than optimal, the researchers found, but none chose places that forced them to endure extreme heat.

“Many species might undergo seasons where conditions are not optimal for growth and reproduction,” said Johannes Overgaard, a biologist at Aarhus University in Denmark and an author of the study. “They just survive the season. But what they can’t survive is temperatures beyond their threshold.”

This is bad news for the insects in Australia, who might find themselves with fewer habitable lands as extreme conditions dominate the continent. Whether this will also hold true for other continents is not yet known, Dr. Overgaard said.

Rock Snot

An unsightly algae known as “rock snot” has been surfacing in lake waters in Eastern Canada.

“It looks like torn-up toilet paper that is attached to rocks,” said John Smol, a biologist at Queen’s University in Ontario who is studying the algae’s growth. “It’s an aesthetic issue, and as it decomposes it becomes a smell issue.”

Rock snot, or didymo, was thought of as an invasive species introduced by humans. But an analysis of fossilized algae in the lakes indicates that it is native.

The algae was present in one lake in Quebec since at least 1970, 36 years before it was first noticed, Dr. Smol’s team found.

Didymo tends to grow in flowing waters. Warmer winters may be producing less ice and snow that disrupt the flow.

Over time, the rock snot will become much more than an eyesore, Dr. Smol said. It will displace other organisms and destroy fish habitats.

Coral Reefs

Ocean acidification endangers coral in every ocean. But researchers haverecently discovered unusual reefs in Palau that are thriving in increasingly acidicified waters.

Ocean acidification occurs when carbon emitted by human activities mixeswith ocean waters. This decreases carbonate ions in the water, which coral andother organisms need to form their protective shells.

Yet in 2012, researchers working in the waters off Palau identified coralreefs that were both extremely acidified and very healthy. What’s differentabout these reefs, said Kathryn Shamberger, anoceanographer at Texas A&M University, is that the waters became acidifiedthrough natural means.

“The growth of the reef itself and the breathing of the organisms onthe reef,” not man-made emissions, added carbon to the water, she said.

In a typical reef these products would be flushed out before they could havemuch effect. But the waters in Palau pool around its many small islands.

Might reefs suffering from man-made acidification survive as well as these?Dr. Shamberger and others are trying to figure thatout.

Eric Sanford

Shellfish

Increasing ocean acidity makes it difficult for marine species to build their shells and, by softening calcium carbonate, makes shells weaker. That’s bad news not only for clams, oysters and scallops, but for tens of thousands of lesser known species — echinoderms like star fish and sea urchins, colonies of tiny invertebrates, reef corals and many others.

In June, The Biological Bulletin devoted an issue to research on ocean calcification with papers and reviews on a large variety of organisms.

“Climate change and ocean acidification are going to manifest themselves in the ways species interact — eating each other, facilitating each other’s growth,” said an editor of the issue, Gretchen Hofmann, a marine biologist at the University of California, Santa Barbara.

And yet, she added, there is some hope. “In coastal areas there are plants that actually change the pH of the water — in a good way. Eel grass and surf grasses can provide refuge from future acidification.”

Sophie McCoy

Coral Algae

Coralline algae are the cement that binds many reefs together. By filling the gaps between corals with a hard outer shell, these algae fortify the reef and provide shelter for growing organisms.

To produce that shell, this special algae — much like oysters and snails — require a steady supply of carbonate. But as carbonate becomes harder and harder to come by in increasingly acid oceans, the once-dominant species of coralline algae can no longer grow shells as thick as they once were. Other species are moving in to claim more territory.

For now, it might not be so bad to give these competitors a chance, said Sophie McCoy, an ecologist with the Plymouth Marine Laboratory in England, who lead a study on the phenomenon when she was at the University of Chicago earlier this year.

“In the short term, I think it might be a good thing in terms of local biodiversity,” she said. In the long run, however, “all the species of this algae will start to be affected.”

That could mean less coral overall, and less habitat for the organisms that call it home.

Michael Francis McElroy for the New York Times

Invasive Species

Biological intruders, from California’s medflies to Florida’s Burmese pythons, cost the United States billions of dollars every year. Rising temperatures and changing weather patterns may make them even harder to control.

“Biology can be very complicated, especially when climate change comes in,” said Andrew Paul Gutierrez, an ecologist at the University of California, Berkeley. “That’s going to affect these species in unknown ways.”

In a book on the subject, Dr. Gutierrez notes one jarring possibility: that higher temperatures may invite still more invasive species into fragile ecosystems.

Malaria

Historically, the highlands of Ethiopia offered protection from deadly, mosquito-borne malaria. But perhaps not for much longer.

The disease was mitigated at higher altitudes, where cooler temperatures kept mosquitoes in check. Now, malaria is spreading into higher elevations during warmer years, then back into lower altitudes when temperatures cool.

Looking at temperature records from the two regions, there is a clear link between the changing climate and higher rates of the disease, said Mercedes Pascual, an ecologist at the University of Michigan.

“The disease is seasonal,” she said. “But climate change here could make the problem much bigger.”

She and her colleagues found that a 1.8 degree Fahrenheit temperature increase could result in an additional three million malaria cases annually in Ethiopia among those under age 15.

A Future as Clouded as Their Past (New York Times)

We won’t ever know what the Anasazi were thinking on the eve of the 13th century when they abandoned the cities they had worked so long to build on the Colorado Plateau. The reasons had something to do with climate — a great drought and, perhaps on top of that, a mini ice age. If that wasn’t enough to defeat a thriving culture, there was the turmoil that came from just not knowing. Why were the sky and earth behaving so strangely? Why wasn’t the old magic working anymore?

The rains were not just sparser. They were no longer coming when they were supposed to — when the seedlings were in the ground waiting for water. Cooler temperatures were putting an earlier end to the growing season. Fields had been overplanted, forests stripped of wood. Crops were failing as people reverted from agriculture to hunting and gathering and fighting violently over food.

Chaco Canyon and Mesa Verde — these grand stone settlements fell silent, repurposed centuries later as national parks and monuments, memorials to the repercussions of ancient climate change.

There are many theories seeking to explain the abandonment, abstracted from faint clues in old rocks and bones and in the patterns of tree rings and pollen deposition. By some measures, there was enough water, just barely, for the Anasazi settlements to hang on. And there is evidence that they had survived drier times. A more complex story has emerged as archaeologists try to infer what they can from changes in architectural styles and pottery design — hints perhaps of a people trying out new rituals, new ways to entreat suddenly indifferent gods.

Something was happening — a slow horror, perhaps so slow that it didn’t feel like a horror, until the Anasazi’s culture began to unwind. Did their leaders engage at first in denial and then quiet deliberation? When that failed, did communities split into factions with the conservatives insisting on standing their ground — clinging to the old ways and waiting for the rains to return — and the liberals pushing for new approaches? Did a visionary arise? Some Moses leading a migration? Or three Moseses leading migrations in different directions?

One way or the other, the Anasazi disintegrated, the people moving southward. Their descendants are believed to live now in the pueblos of New Mexico and Arizona, perched on mesa tops and hugging the banks of the Rio Grande.

In modern times, many of these pueblos divide themselves, for reasons they keep from the anthropologists, into kinship groups called summer and winter people or squash and turquoise people. Could these divisions be imprints left from that 13th-century upheaval?

It is frustrating how little is known. Compared with the Byzantines, the Normans, or the Mongols, the Anasazi left such faint traces, like ripples from the radiation of their own Big Bang. They have an oral history but it is mostly secret. And there is only so much that can be derived from mythology. The closest we have to records are the crude rock etchings called petroglyphs. Were these symbols in a rudimentary language or just doodling?

Our own deliberations — imprinted onto electromagnetic waves — have been pulsing outward from Earth since the first radio news shows in the 1920s and 30s, interspersed with the “Grand Ole Opry” and the “Amos ’n’ Andy” show.

By now broadcasts about greenhouses gases, melting ice caps and rising sea levels are rippling far beyond Alpha Centauri, along with the carefully calculated outrage of Rush Limbaugh and Glenn Beck. As the waves travel farther, they converge asymptotically toward a vanishing point. Even at their strongest they might seem as esoteric to curious aliens as Anasazi rock art.

Our later emanations, if they are ever understood, might tell of great feats of geoengineering: swarms of orbiting mirrors to bounce back sunlight, oceans fertilized to create carbon-absorbing algae blooms.

The Anasazi had to make do with simpler technology — water catchment basins, irrigation channels. But when all else failed at least they had somewhere to go.

Stuck here on Earth, do we embrace the Anthropocene — this new geological epoch in which the human race has become its own force of nature? Or do we hunker down for the sixth extinction? Faced with the dilemma, we cleave as naturally as a crystal into factions, like the squash people and the pumpkin people.

Diane Ackerman is one of the latest to join the environmental optimists, who believe that the same kind of technological prowess that got us into this mess will help us adapt to it, in ways we can only begin to imagine. (Her new book, “The Human Age: The World Shaped by Us” is reviewed on Page 5.)

With her following, Ms. Ackerman may become the counterpart to Bill McKibben, the environmentalist whose book “Eaarth” (he changed the name of the planet since we have irremediably transformed the place) called for a return to simpler times with backyard farms instead of lawns and decentralized green energy. The Anasazi with solar panels on the roof.

Finally there is the 25 percent of Americans (“cool skeptics,” as a Gallup poll called them) who don’t believe the keepers of the models — the interpreters of the signs. As we flail we are generating so much data that future archaeologists, if they exist, may be overwhelmed — the opposite problem presented by the Anasazi.

More than 700 years after their fall, we have the knowledge to tell us what is going wrong this time with the atmosphere. But that has made it no easier to agree on a plan. Science can only lay the case out on the table. For all our supercomputers and climatological models, what happens next will come down to something unpredictable: the meteorology of the human mind.

Forecasts: Hopes and Fears About Climate Change (New York Times)

Two dozen scientists, authors, and world and national figures answered two questions: What is your greatest worry about climate change? What gives you hope? Here are some of their answers, condensed for space.

JANE LUBCHENCO, Former administrator, National Oceanic and Atmospheric Administration

I worry about oceans becoming more corrosive, decimating both fisheries and coral reefs. Oceans have already become 30 percent more acidic since the beginning of the Industrial Revolution; if business-as-usual carbon emissions continue, oceans are likely to be 150 percent more acidic by the end of this century. Yikes!

I take heart in knowing that social change can happen very rapidly once a tipping point is reached, that young people are bringing new passion and creativity to the issue, and that climate change is being seen increasingly as the moral issue it is.

TENZIN GYATSO, 14th Dalai Lama of Tibet

The worst possible aspect of climate change is that it will be irreversible and irrevocable. Therefore, there is the urgency to do whatever we can to protect the environment while we can.

When I was young, even I did not really think about the environment, nor did I hear much about it from others. Today, more and more people are trying to take action. We are beginning to look at this planet as our only home, and I am hopeful that this will lead to the generation of a genuine sense of universal responsibility. We can do this.

MICHAEL R. BLOOMBERG, Former mayor of New York City and special United Nations envoy for cities and climate change

Something like 90 percent of the world’s cities are on coasts, and in most places, the most vulnerable people in those cities will feel the worst impacts. We have a responsibility to do something about that. We can’t afford to sit back, cross our fingers and hope for the best.

A tremendous amount of progress is being made by cities all around the world. Cities account for some 70 percent of the emissions that cause climate change, so together they can make a big difference. In New York City back in 2007, we set a goal of reducing our carbon footprint 30 percent by 2030, and we got to a 19 percent reduction in just six years.

Mayors have powers they can use to address climate change immediately. They have control over many of the things that create emissions — like transportation and buildings — and they can invest in infrastructure. They’re not interested in turning the issue into a big political fight. They’re the ones most directly responsible for people’s safety and welfare — and they recognize the dangers of inaction.

JEFFREY SACHS, Director, Earth Institute of Columbia University

The oil industry has lobbied Washington to a state of paralysis, and as is so often true, greed is at the root of the crisis, with the politicians getting in line to feed at the oil trough. The climate deniers are not the real problem. Their transparent propaganda and misdirections are laughable; their scientific ignorance is impossible to miss. The real problem is the cowardice and greed of those who absolutely know better, both in government and industry.

We are living in an age of technological breakthroughs that could transform the world economy to a low-carbon energy system by midcentury. Solar, wind, geothermal, carbon sequestration, safe nuclear energy, and energy efficiency are all part of the mix. The oil industry should cooperate, rather than faking it or dodging it as until now.

BARBARA KINGSOLVER, Novelist; author of the memoir “Animal, Vegetable, Miracle

My fear: Catastrophic extinction. We don’t get to make natural laws. Natural law made us, and it ultimately will unmake us. What makes me very sad is that we’re going to take so many species down with us.

My hope: We in the United States finally seem to be coming to the table after decades of either denial or argument. It seems as if denial as a political strategy has run its course and that we are stepping up to our responsibilities. I hope that’s true.

ALAN I. LESHNER, Chief executive, American Association for the Advancement of Science

Ideology and intuition sometimes appear to be trumping science. So people deny the evidence even as it increases. I fear that the pace at which the public understands that the climate is changing, and puts pressure on the political system, will be too slow.

We are seeing that communicating scientific knowledge has had an effect, and that makes me happy! The deniers have less and less credibility as the public understands the scientific consensus more and more.

NEIL DeGRASSE TYSON, Director, Hayden Planetarium

I find that to worry about things is to invest emotional energy in ways that do not lead to change. Always better to do something about a problem than to worry about it.

What I expect will happen in the coming decades is that beachfront real estate, some of the most expensive in the housing marketplace, will become overrun by storm surges with enough frequency that it will force the wealthiest class (who might have previously been in denial of the phenomenon) to recognize the problem and take action, actions they can take since they are typically captains of industry and are in power and in control.

JERRY BROWN, Governor of California

A huge challenge of climate change lies in the fact that for its solution, countries all over the world must collaborate in ways that are entirely unprecedented.

Each nation-state has to be fully engaged and take decisive steps outside the conventional economic comfort zone. And that requires more statesmanship that is currently in evidence in any of those countries. The mythology of the market and economistic view of life has to be transcended so people understand that a decent and sustainable quality of life requires a very different philosophy than the one that governs contemporary societies.

Here in California, we’re leading the nation in the economic recovery and the creation of jobs, and we are pioneering climate change strategies across a broad front. We have a robust cap-and-trade system. We have a goal of one-third renewable energy in the electricity sector; we’re already at 22 percent. We have the strictest building standards in the world. We have a goal of over a million electric vehicles; we’ve got our first 100,000! We have a certain momentum in California. There are other states where this is also true.

JAMES E. HANSEN, Climate scientist, emeritus director at NASA Goddard Institute for Space Studies

The reason it’s a really dangerous situation is that the climate system does not respond quickly to the forces we apply to it. That means that we have not witnessed the impact of the gases we’ve already added to the atmosphere. We’re waiting for the public to see enough to demand effective government response.

The public doesn’t see that much yet, but there’s more in the pipeline. We are pumping energy into the ocean at a rapid rate; that energy is accumulating, and its biggest impact is going to be on ice shelves. The sea level will go up many meters. That means all coastal cities will be doomed if we stay on fossil fuel business as usual.

The upside is that the only policy that will work is making the price of fossil fuels match their cost. We have an organization determined to focus on exactly that issue: the Citizens Climate Lobby. It’s growing rapidly. Things are changing. But not fast enough.

MARIO J. MOLINA, Co-recipient of the 1995 Nobel Prize for his research on the chemistry of the ozone layer

What worries me most is the irrationality of certain interest groups preventing society from addressing the problem. Republicans in Congress are preventing action on an efficient solution such as a carbon tax.

There is a solution at hand. It doesn’t cost as much as the deniers claim. The Montreal Protocol [on ozone depletion] showed that you could solve such global problems. It would have been much more expensive not to solve it.

ELIZABETH KOLBERT, Author of “The Sixth Extinction: An Unnatural History

For the last 10,000 years or so, the climate’s been relatively stable. But if you start imagining a world with a constantly changing climate, one where, say, rainfall patterns shift dramatically every few decades, then you begin to realize how dependent we all are on that stability. And the world we’re creating is that constantly changing one.

So I worry about just about everything, starting with the basics. There are 7.2 billion people on the planet right now, and we all need to eat.

Hopefulness or a lack of it is really not the issue here. We’ve already caused a lot of damage; there’s a lot of warming that’s in effect baked into the system. We’re capable of causing a great deal more damage, and we’re also capable of limiting that damage. That’s the choice at this point, and we need to face up to that.

J. MARSHALL SHEPHERD, Former president, American Meteorological Society

It bothers me that people think there’s a big debate in science when there isn’t. Being concerned about climate change is not some whim. When I go to the mall or to Walmart, people ask, “Do you really believe in climate change?” That’s like asking, “Do you believe in gravity?” I mean, the science is clear.

What gives me optimism is that many of the people who question the science are of an older generation. The kids get it. When I go to my children’s Scout meetings or when I talk to students on campus, they get beyond the misinformation and politics.

THE REV. MITCHELL C. HESCOX, President, Evangelical Environmental Network

Climate change is the greatest moral challenge of our time because it impacts every single soul in the world. In the conservative Christian world in the United States, we’ve gotten caught up in political partisanship. I’d like to see climate change as a Christian issue and not a partisan issue.

We are the stewards of God’s creation. We believe that the earth’s creation belongs to God and that we are charged to care for it.

When we started this [network] five years ago, we had 15,000 people we regularly communicated with on this issue. Today it approaches 400,000. It means that we’re starting to overcome the partisan divide and the tide is slowly turning.

DIANA H. WALL, Director, School of Global Environmental Sustainability, Colorado State University

What keeps me up, the thing that really drives me nuts, is that the rate of change is so fast. I work in one of the most extreme ecosystems on Earth: the Antarctic Dry Valleys. It is the coldest, windiest, driest place on Earth. We’re seeing warming events and very sunny events there, and this is causing a change in the organisms I study. These species have adapted to the conditions there. We don’t know what the impact will be on them or us.

My students give me hope.

MARTIN REES, Astrophysicist, University of Cambridge

I have a lot more fears than hopes. One aspect that particularly troubles me is that economists tend to underprioritize efforts at mitigation of atmospheric carbon, because the really serious downside of inaction won’t be experienced until the 22nd century and beyond. If action is delayed, it may then be too late to avoid irreversible runaway changes.

We shouldn’t discriminate against our fellow humans on grounds of date of birth. The lifetime welfare of the newborn should rate as highly as that of the already middle-aged. Indeed, many philosophers would assign equal value to the rights of those not yet born.

For them, foreclosing the potentialities of all future generations would be so catastrophic that we should strive to reduce even the tiniest probability that this could happen.

CHRISTINE TODD WHITMAN, Former governor of New Jersey and former administrator, Environmental Protection Agency

What keeps me up at night are people who talk in absolutes. It’s the people who say “humans cause it” or “people have no role in it,” full stop. Science is not exact and the truth is in between. By taking the extreme position, they give an opening to the other side, and then people stop listening.

What gives me hope is that there are signs that the American people are beginning to relate some of the frequent weather extremes to climate.

Since 1980 our economy has grown, our population has grown and our energy use has grown, and yet our overall pollution has gone down. We are perfectly capable of implementing environmental regulation without stopping economic growth.

KATHARINE HAYHOE, Director, Climate Science Center, Texas Tech University

What troubles me as a scientist is the potential for vicious feedbacks within the climate system. The warming that we cause through all the carbon we produce could cause a series of cascading impacts that could lead to a much greater warming. The more carbon we produce, the higher the likelihood of these unpredictable risks.

What makes me hopeful are people. I’ve been working with cities, states and regional transportation councils, and none of them have to be convinced of the reality of this problem. I was sitting next to an assistant city manager for Dallas, a town not known for being green, and she blew me away with her list of amazing things Dallas has done to save energy. People are preparing for change.

MARGARET ATWOOD, Poet and novelist, author of “The Year of the Flood

The most worrisome thing is the potential death of the ocean. If it dies, we die.

What gives me hope is that more and more people are aware of the dangers we face, and many smart people are at work on solutions. Our smart brains got us into this. Let’s see if they can get us out.

FREEMAN J. DYSON, Theoretical physicist, Institute for Advanced Study

What worries me is that many people, including scientists and politicians, believe a whole lot of dogmatic nonsense about climate change. The nonsense says that climate change is a terrible danger and that it is something we could do something about if we wanted to. The whole point is to scare people, and this has been done very successfully.

Climate has always been changing, and climate has always been lousy. It has always been a background to existence that on the whole we’ve learned to cope with pretty well. What I feel happy about is that there are a lot of ordinary people with common sense who don’t believe the nonsense.

MARLENE MOSES, Nauru’s ambassador to the United Nations, chairwoman of the Alliance of Small Island States

When I go home and look at the deteriorating situation there — increased droughts, the ocean washing away the coast — I can’t help but be fearful for what the future may hold for Nauru’s children and grandchildren. How will they adapt? Will the international community be there for them? These are most distressing questions to which I don’t yet have answers.

GLORIA STEINEM, Co-founder and former editor, Ms. Magazine

Thinking about climate change used to give me images of the sun burning down and icebergs melting — horrific, but also impersonal and far away. Now I have intimate fears of storms and floods that drive us off this island of Manhattan, and fires that send thousands fleeing — in other words, just an acceleration of what we’re already seeing.

Like millions of others in public opinion polls, I’m willing to lower my standard of living to help create a turning point. We’re waiting for a practical, coordinated, understandable set of instructions that counters the Kochs, the deniers, the profiteers. Meanwhile, we try to do whatever we can.

Somehow, I find comfort in the idea that the earth is a living organism with a will of its own. The global women’s movement gives me hope because women are trying to take control of their own bodies and reproduction, which is even more basic than production. Everything we know says that when women can decide whether and when to have children, growth slows down to a little over replacement level. And that would be the single biggest long-term relief for the environment.

MARY ROBINSON, Former president of Ireland, former United Nations High Commissioner for human rights

I’m a grandmother with five grandchildren. What will they say about what we did or didn’t do?

It’s Not Genghis Khan’s Mongolia (New York Times)

ULAN BATOR, Mongolia — For all of his victories and skills, Genghis Khan always insisted that the god Tengri — the Eternal Blue Sky — deserved the credit for his triumphant success in uniting the vast Mongol Empire in the early 13th century.

Now 21st-century science may be proving him right. Not long ago, researchers studying ancient tree rings found evidence that the Great Khan rose to power during an exceptionally mild 15-year stretch.

Back-to-back years of plentiful rain and favorable temperatures — known as pluvials, the opposite of droughts — promoted vegetation growth, the researchers believe, and that in turn supported the livestock needed to power an army.

“The Mongol Empire pluvial was quite exceptional in its duration,” said Neil Pederson, an ecologist at Harvard Forest in central Massachusetts. “It was the only one in the past 1,000 years that lasted more than 10 years, so it’s really a singular event.”

These days, Mongolia’s climatic tides have been shifting toward another extreme. A 10-year drought and heat wave from 2000 to 2010, according to the tree ring data, was the most severe the country had had in a millennium.

“I’m more and more convinced that the only way we can understand this 21st-century event is within the context of climate change,” said Amy Hessl, a geographer at West Virginia University. “And the human side of that — combined with a constellation of other factors — is going to be incredible.”

Today, Mongolia is largely herders, not warriors. Sandwiched between Russia and China, it has almost three million people in a vast tract of desert and rolling steppe grassland, punctuated by mountains and forests. Climate continues to significantly shape the lives of Genghis Khan’s descendants, around one-third of whom still practice the seminomadic herding of their ancestors, moving their house — traditionally, a dome-shaped tent called a ger — with the seasons.

While televisions and solar panels are a common sight in modern gers, herders still rely on thousands of years of collective knowledge to thrive in the harsh Mongolian environment, where the temperature regularly dips below minus 15 degrees Fahrenheit in winter. Yet the predictable ebb and flow of warmth and cold, rain and snow, has begun to falter in recent years.

“I don’t know why the weather has become unusual, but I’m very worried about it,” said Urgamaltsetsg Suvita, 47, a herder in the Gobi Desert. Summer is hotter and drier and plagued by sandstorms, she said, and winter brings too much snow or too little.

In 2010, an extreme snowstorm killed her flock of livestock — nearly 1,000 animals, including horses, sheep and goats. “Winter is no longer winter,” she said.

Like much of the world, Mongolia is already experiencing the effects of climate change. The country’s average annual temperature has risen more than 3.8 degrees Fahrenheit since 1940; paradoxically, winter months have grown colder over the past 20 years. Streams and lakes have begun to dry up, and fires frequently blaze across millions of acres of steppe and forest.

“The steppe ecosystem is burning and burning and burning,” said Oyunsanaa Byambasuren, a lecturer in forestry at the National University of Mongolia. “But we really don’t have enough specialists or professionals dealing with those issues.”

Dzuds — extreme winter events that cause mass livestock die-offs — also seem to be increasing in frequency and intensity. From 1999 to 2002, a succession of winter dzuds followed by summer droughts killed 30 percentof all livestock in Mongolia, and a 2010 dzud claimed 8.8 million livestock — losses equivalent to 4.4 percent of the country’s economic output.

“Wealth in much of Mongolia is measured in animals,” said Nicole Davi, a research scientist at Lamont-Doherty Earth Observatory and at William Paterson University. “If you lose all of your animals, you lose everything.”

Ayush Ish, 69, has lived in the Gobi Desert all her life. She and her husband lost their flock of goats and sheep in the 2002 dzud and drought, then slowly rebuilt it with the help of 50 animals allocated by the government. But when the 2010 dzud struck, all but 20 died. Around the same time, her husband died as well.

“I don’t know if it will happen again,” she said, tears running down her cheeks. “I can only hope that we’re entering a good period now.”

Like many rural Mongolians who follow a shamanistic belief system, Ms. Ish says that mining — which has recently become widespread around the country — is to blame for the changing weather patterns. Troy Sternberg, a geographer at the University of Oxford, said that “under the Mongolian belief system, the earth and sky are connected, so if you take gold out of the ground, you’re disrupting the natural rhythms of weather and climate.”

Whether or not that is true, the rise of mining — along with overgrazing by herders chasing the cashmere market — has led to wide desertification. Some studies indicate that 70 percent of Mongolia’s grasslands are degraded.

Taken together, these patterns bode ominously for the herders’ way of life. A team of Mongolian and international experts warned in a 2009 report that such trends “may lead to the end of the Mongolian traditional way of animal husbandry as we know it, that at onetime was the very core of the entire nomadic civilization.”

Some herders have already reached that breaking point. After the 1999 to 2002 dzuds alone, 180,000 people moved to the capital, Ulan Bator, in search of a better life. “The movement from a rural, agrarian life to an urban industrial one is not necessarily a bad thing if people are interested in doing other things that are tied to a more diverse economy,” said Maria Fernandez-Gimenez, an ecologist at Colorado State University. “But opportunities and services have to exist to enable that.”

Those who reach the capital usually settle in the ger district, a sprawling, makeshift neighborhood that encircles the city and creeps into the surrounding valleys. Although the skyscrapers of downtown are in eyesight, basic services are luxuries. Families must trek up to a mile to collect water from communal wells, and in winter, they burn coal and garbage to keep warm, helping to make Ulan Bator one of the world’s most polluted cities.

Khishigee Shuurai, 36, moved from western Mongolia to the capital around 15 years ago. In 2002, after losing their flock, her parents joined her in the city. Then her father died of a heart attack. Before that, she said, he frequently expressed a longing to return to the countryside.

For many, however, life here is preferable to the uncertainty and harshness of nomadic herding. Ms. Shuurai, a school custodian and mother of four, does not share her father’s regrets.

She and her husband, a construction worker, have jobs, and they recently got electricity in their ger. Her 7-year-old daughter was honored as the top student in her class, and her 12-year-old son wants to become an engineer.

“There’s many reasons to stay,” she said. “I don’t want to go back.”

Firelight talk of the Kalahari Bushmen (University of Utah)

Did tales told over fires aid our social and cultural evolution?

SALT LAKE CITY, Sept. 22, 2014 – After human ancestors controlled fire 400,000 to 1 million years ago, flames not only let them cook food and fend off predators, but also extended their day.

A University of Utah study of Africa’s Kalahari Bushmen suggests that stories told over firelight helped human culture and thought evolve by reinforcing social traditions, promoting harmony and equality, and sparking the imagination to envision a broad sense of community, both with distant people and the spirit world.

Researchers previously studied how cooking affected diets and anatomy, but “little is known about how important the extended day was for igniting the embers of culture and society,” anthropology professor Polly Wiessner writes in a study published online today in the journal Proceedings of the National Academy of Sciences.

“There is something about fire in the middle of the darkness that bonds, mellows and also excites people. It’s intimate,” says Wiessner, who has studied the Bushmen for 40 years. “Nighttime around a fire is universally time for bonding, for telling social information, for entertaining, for a lot of shared emotions.”

Wiessner’s study, which she calls “exploratory,” analyzed scores of daytime and firelight conversations among !Kung Bushmen – also known as Ju/’hoansi Bushmen – some 4,000 of which now live in the Kalahari Desert of northeast Namibia and northwest Botswana. (The exclamation, slash and apostrophe symbols represent click sounds in their language.) They are among several groups of Kalahari Bushmen.

Why study the campfire tales of Bushmen?

“We can’t tell about the past from the Bushmen,” Wiessner says. “But these people live from hunting and gathering. For 99 percent of our evolution, this is how our ancestors lived. What transpires during the firelit night hours by hunter-gatherers? It helps answer the question of what firelit space contributes to human life.”

She writes: “Stories are told in virtually all hunter-gatherer societies; together with gifts, they were the original social media.”

From the Workaday World to Nights of Bonding and Wonder

In her study, “Embers of Society: Firelight Talk among the Ju/’hoansi Bushmen,” Wiessner says archaeological evidence indicates human ancestors had sporadic control of fire 1 million or more years ago, and regularly used it after 400,000 years ago.

“Fire altered our circadian rhythms, the light allowed us to stay awake, and the question is what happened in the fire-lit space? What did it do for human development?” asks Wiessner, who earlier this year was among three University of Utah researchers elected to the National Academy of Sciences.

Wiessner says !Kung Bushmen hold firelight gatherings most nights in groups of up to 15 people. A camp has hearths for each family, but at night people often converge at a single hearth. She analyzed only conversations involving five or more people.

Firelight stories deal with topics such as past hunts, fights over meat, marriage, premarital customs, murder, bush fires, birth, getting lost, interactions with other groups, truck breakdowns, being chased by animals, disputes and extramarital affairs. And there also are traditional myths.

For her study, Wiessner analyzed two sets of data:

  • Notes she took in 1974 (initially for another purpose) of 174 daytime and nighttime conversations at two !Kung camps in northwest Botswana. Each conversation lasted more than 20 to 30 minutes and involved five to 15 people.
  • Digital recordings, transcribed by educated Bushmen, of 68 firelight stories Wiessner originally heard in the 1970s but came back to have retold and recorded during three visits in 2011-2013 to !Kung villages in Botswana and Namibia.

Wiessner found daytime conversations differed much from firelight discussions. Of daytime conversations, 34 percent were complaints, criticism and gossip to regulate social relationships; 31 percent were economic matters, such as hunting for dinner; 16 percent were jokes; only 6 percent were stories and the rest were other topics

But at night, 81 percent of the conversations involved stories, and only 7 percent were complaints, criticism and gossip and 4 percent were economic.

Bonding with People Near and Far – and with the Supernatural

Wiessner found how conversations reinforced major !Kung social institutions and values: arranged marriages, the kinship system, a social structure based on equality, the sharing of food during times of hardship, land rights, trance healing and xaro, a system of exchange that involved pledges of mutual assistance, including housing and food, in troubled times.

“What I found was a big difference between day and night conversation, the kinds of information transmitted and the use of imaginary thought,” Wiessner says.

“Day conversation has a lot to do with economic activities – working, getting food, what resources are where,” she says. “It has a lot to do with social issues and controls: criticism, complaints and gripes.”

“At night, people really let go, mellow out and seek entertainment. If there have been conflicts in the day, they overcome those and bond. Night conversation has more to do with stories, talking about the characteristics of people who are not present and who are in your broader networks, and thoughts about the spirit world and how it influences the human world. You have singing and dancing, too, which bonds groups.”

Healers dance and go into trances, “travel to god’s village and communicate with the spirits of deceased loved ones who are trying to take sick people away,” Wiessner says.

She says nonhuman primates don’t maintain mutually supportive ties outside their group: “We are really unique. We create far-flung ties outside our groups.”

Such extended communities allowed humans “to colonize our planet because they had networks of mutual support, which you see expressed today in our capacity for social networking” she adds. “Humans form communities that are not together in space, but are in our heads – virtual communities. They are communities in our heads. For the Bushmen, they may be up to 120 miles away.”

Wiessner suggests that firelight stories, conversations, ceremonies and celebrations sparked human imagination and “cognitive capacities to form these imagined communities, whether it’s our social networks, all of our relatives on Earth or communities that link us to the spirit world.” She says they also bolstered the human ability to “read” what others are thinking – not just their thoughts or intentions, but their views toward other people.

What Has Electricity Done to Us?

Examining how firelight extended the day prompted Wiessner to wonder about modern society, asking, “What happens when economically unproductive firelit time is turned to productive time by artificial lighting?”

Parents read stories or show videos to their children, but now, “work spills into the night. We now sit on laptops in our homes. When you are able to work at night, you suddenly have a conflict: ‘I have only 15 minutes to tell my kids a bedtime story. I don’t have time to sit around and talk.’ Artificial light turned potential social time into potential work time. What happens to social relations?”

Her research raises that question, but doesn’t answer it.

Força-tarefa internacional fará diagnóstico sobre polinização no mundo (Fapesp)

23 de setembro de 2014

Primeira avaliação da Plataforma Intergovernamental de Biodiversidade e Serviços Ecossistêmicos será sobre polinizadores, polinização e produção de alimentos. Trabalho é coordenado por pesquisador inglês e por brasileira (foto: Wikimedia)

Agência FAPESP – Um grupo de 75 pesquisadores de diversos países-membros da Plataforma Intergovernamental de Biodiversidade e Serviços Ecossistêmicos (IPBES, na sigla em inglês), que reúne 119 nações de todas as regiões do mundo, fará uma avaliação global sobre polinizadores, polinização e produção de alimentos.

O escopo do projeto foi apresentado na última quarta-feira (17/09) em São Paulo, no auditório da FAPESP, em um encontro de integrantes do organismo intergovernamental independente, voltado a organizar o conhecimento sobre a biodiversidade no mundo e os serviços ecossistêmicos.

“A ideia do trabalho é avaliar todo o conhecimento existente sobre polinização no mundo e identificar estudos necessários na área para auxiliar os tomadores de decisão dos países a formular políticas públicas para a preservação desse e de outros serviços ecossistêmicos prestados pelos animais polinizadores”, disse Vera Imperatriz Fonseca, do Instituto de Biociências da Universidade de São Paulo (USP) e do Instituto Tecnológico Vale Desenvolvimento Sustentável (ITVDS), à Agência FAPESP.

“Já estamos conhecendo melhor o problema [da crise da polinização no mundo]. Agora, precisamos identificar soluções”, disse a pesquisadora, que coordena a avaliação ao lado de Simon Potts, professor da University of Reading, do Reino Unido.

De acordo com Fonseca, há mais de 100 mil espécies de animais invertebrados polinizadores no mundo, dos quais 20 mil são abelhas. Além de insetos polinizadores – que serão o foco do relatório –, há também cerca de 1,2 mil espécies de animais vertebrados, tais como pássaros, morcegos e outros mamíferos, além de répteis, que atuam como polinizadores.

Estima-se que 75% dos cultivos mundiais e entre 78% e 94% das flores silvestres do planeta dependam da polinização por animais, apontou a pesquisadora.

“Há cerca de 300 mil espécies de flores silvestres que dependem da polinização por insetos”, disse Fonseca. “O valor anual estimado desse serviço ecossistêmico prestado por insetos na agricultura é de US$ 361 bilhões. Mas, para a manutenção da biodiversidade, é incalculável”, afirmou.

Nos últimos anos registrou-se uma perda de espécies nativas de insetos polinizadores no mundo, causada por, entre outros fatores, desmatamento de áreas naturais próximas às lavouras, uso de pesticidas e surgimento de patógenos.

Se o declínio de espécies de insetos polinizadores se tornar tendência, pode colocar em risco a produtividade agrícola e, consequentemente, a segurança alimentar nas próximas décadas, disse a pesquisadora.

“A população mundial aumentará muito até 2050 e será preciso produzir uma grande quantidade de alimentos com maior rendimento agrícola, em um cenário agravado pelas mudanças climáticas. A polinização por insetos pode contribuir para solucionar esse problema”, afirmou Fonseca.

Segundo um estudo internacional, publicado na revista Current Biology, estima-se que o manejo de colmeias de abelhas utilizadas pelos agricultores para polinização – como as abelhas domésticas Apis mellifera L, amplamente criadas no mundo todo – tenha aumentado em cerca de 45% entre 1950 e 2000.

As áreas agrícolas dependentes de polinização, no entanto, também cresceram em mais de 300% no mesmo período, apontam os autores da pesquisa.

“Apesar de ter aumentado o manejo de espécies de abelhas polinizadoras, precisamos muito mais do que o que temos no momento para atender às necessidades da agricultura”, avaliou Fonseca.

O declínio das espécies de polinizadores no mundo estimula a polinização manual em muitos países. Na China, por exemplo, é comum o comércio de pólen para essa finalidade, afirmou a pesquisadora.

“Na ausência de animais para fazer a polinização, tem sido feita a polinização manual de lavouras de culturas importantes, como o dendê e a maçã. No Brasil se faz a polinização manual de maracujá , tomate e de outras culturas”, disse.

Falta de dados

Segundo Fonseca, já há dados sobre o declínio de espécies de abelhas, moscas-das-flores (sirfídeos) e de borboletas na Europa, nos Estados Unidos, no Oriente Médio e no Japão.

Um estudo internacional, publicado no Journal of Apicultural Research, apontou perdas de aproximadamente 30% de colônias de Apis mellifera L em decorrência da infestação pelo ácaro Varroa destructor, que diminui a vida das abelhas e, consequentemente, sua atividade de polinização nas flores, em especial nos países do hemisfério Norte.

Na Europa, as perdas de colônias de abelhas em decorrência do ácaro podem chegar a 53% e, no Oriente Médio, a 85%, indicam os autores do estudo. No entanto, ainda não há estimativas sobre a perda de colônias e de espécies em continentes como a América do Sul, África e Oceania.

“Não temos dados sobre esses continentes. Precisamos de informações objetivas para preenchermos uma base de dados sobre polinização em nível mundial a fim de definir estratégias de conservação em cada país”, avaliou Fonseca. “Também é preciso avaliar os efeitos de pesticidas no desaparecimento das abelhas em áreas agrícolas, que têm sido objeto de estudos e atuação dos órgãos regulatórios no Brasil.”

Outra grande lacuna a ser preenchida é a de estudos sobre interações entre espécies de abelhas polinizadoras nativas com as espécies criadas para polinização, como as Apis mellifera L.

Um estudo internacional publicado em 2013 indicou que, quando as Apis mellifera L e as abelhas solitárias atuam em uma mesma cultura, a taxa de polinização aumenta significativamente, pois elas se evitam nas flores e mudam mais frequentemente de local de coleta de alimento, explicou Fonseca.

De acordo com a pesquisadora, uma solução para a polinização em áreas agrícolas extensas tem sido o uso de colônias de polinizadores provenientes da produção de colônias em massa, como de abelhas Bombus terrestris, criadas em larga escala e inclusive exportadas.

Em 2004, foi produzido 1 milhão de colônias dessa abelha para uso na agricultura.

Na América do Sul, o Chile foi o primeiro país a introduzir essas abelhas para polinização de frutas e verduras. Em algumas áreas onde foi introduzida, entretanto, essa espécie exótica de abelha mostrou ser invasora e ter grande capacidade de ocupar novos territórios.

“É preciso estudar mais a interação entre as espécies para identificar onde elas convivem, qual a contribuição de cada uma delas na polinização e se essa interação é positiva ou negativa”, indicou Fonseca.

“Além disso, a propagação de doenças para as espécies nativas de abelhas causa preocupação e deve ser um foco da pesquisa nos próximos anos”, indicou.

Problema global

De acordo com Fonseca, a avaliação intitulada Polinizadores, polinização e produção de alimentos, do IPBES, está em fase de redação e deverá ser concluída no fim de 2015.

Além de um relatório técnico, com seis capítulos de 30 páginas cada, a avaliação também deverá apresentar um texto destinado aos formuladores de políticas públicas sobre o tema, contou.

“A avaliação sobre polinização deverá contribuir para aumentar os esforços de combate ao problema do desaparecimento de espécies de polinizadores no mundo, que é urgente e tem uma relevância política e econômica muito grande, porque afeta a produção de alimentos”, afirmou.

A avaliação será o primeiro diagnóstico temático realizado pelo IPBES e deverá ser disponibilizada para o público em geral em dezembro de 2015. O painel planeja produzir nos próximos anos outros levantamentos semelhantes sobre outros temas como espécies invasoras, restauração de habitats e cenários de biodiversidade no futuro.

Uma estratégia adotada para tornar os diagnósticos temáticos mais integrados foi a criação de forças-tarefa – voltadas à promoção da capacitação profissional e institucional, ao aprimoramento do processo de gerenciamento de dados e informações científicas e à integração do conhecimento tradicional indígena e das pesquisas locais aos processos científicos –, que deverão auxiliar na produção do texto final.

“O IPBES trabalha em parceria com a FAO [Organização das Nações Unidas para a Alimentação e a Agricultura], Unep [Programa das Nações Unidas para o Meio Ambiente], CBD [Convention on Biological Diversity], Unesco [Organização das Nações Unidas para a Educação, a Ciência e a Cultura] e todos os esforços anteriores que trataram do tema de polinização”, afirmou Fonseca.

A polinização foi o primeiro tópico a ser escolhido pelos países-membros da plataforma intergovernamental, entre outras razões, por ser um problema global e já existir um grande número de estudos sobre o assunto, contou Carlos Joly, coordenador do Programa FAPESP de Pesquisas em Caracterização, Conservação, Restauração e Uso Sustentável da Biodiversidade (BIOTA-FAPESP) e membro do Painel Multidisciplinar de Especialistas do IPBES.

“Como já há um arcabouço muito grande de dados sobre esse tema, achamos que seria possível elaborar rapidamente uma síntese. Além disso, o tema tem um impacto global muito grande, principalmente por estar associado à produção de alimentos”, avaliou Joly.

Os 75 pesquisadores participantes do projeto foram indicados pelo Painel Multidisciplinar de Especialistas do IPBES, que se baseou nas indicações recebidas dos países-membros e observadores da plataforma intergovernamental.

Dois do grupo são escolhidos para coordenar o trabalho, sendo um de um país desenvolvido e outro de uma nação em desenvolvimento.

“O convite e a seleção da professora Vera Imperatriz Fonseca como coordenadora da avaliação é reflexo da qualidade da ciência desenvolvida nessa área no Brasil e da experiência dela em trabalhar com diagnósticos nacionais”, avaliou Joly. “Gostaríamos de ter mais pesquisadores brasileiros envolvidos na elaboração dos diagnósticos do IPBES.”

California water witches see big business as the drought drags on (The Guardian)

Dowsers, sometimes known as ‘water witches,’ are in high demand in drought-stricken California, where four dry years find farmers and vintners taking desperate measures

Sharron Hope has been a dowser since 1997. Markedly cheaper than hiring a hydrogeologist – which can cost as much as $50,000 – Hope OFFERS her services for around $500 a consultation. Video: Mary Catherine O’Connor

Outside of a farmhouse on a 1,800-acre organic dairy farm near Oroville, California, Sharron Hope bends over a printout of a Google Earth map, holding a small jade Buddha pendant. The map shows a small section of the farm to the east, and Hope is hunting for water. As the pendant swings, she notes a subtle change in motion that, she says, indicates she has found some.

Is there any significance to the jade? No, she says, I just like it. Plus, she adds, “I figure Buddha’s gotta know.”

Hope is a water dowser, or someone who uses intuition, energy VIBRATIONS and divining rods or pendulums to mark the best spots for wells.

As California rounds the corner towards a four-year historic drought, many farmers and vintners have become completely reliant on groundwater. After divvying surface water allotments to satisfy urban, ecosystem and industrial needs, farmers in many parts of the state received little or no irrigation water from state agencies this year. In a normal year, allotments would cover roughly two-thirds of farmers’ needs.

Under these severe drought conditions, the success or failure of a well can mean the success or failure of a farm or vineyard, so before the drill bit hits the dirt, landowners need an educated guess as to where to find the most productive well site on their property. To get that, they can call in a professional hydrogeologist, which can cost tens of thousands of dollars – or they can drop a fraction of the cost on a dowser, such as Hope.

Despite a distinct lack of empirical evidence regarding dowsers’ efficacy, demand is high and dowsers’ phones are ringing off the hook.

“I’ve gotten far more calls this year from farmers looking for a water dowser than in most years,” says Sacramento-based Donna Alhers, who heads the Sierra Dowsers, a chapter of the American Society of Dowsers.

Water dowsers from around the state are also seeing a spike in demand. “I’m getting a lot of calls from people whose wells have run dry,” Hope says.

Where did dowsing come from?

The exact origins of dowsing are murky, but its roots can be traced back as far as the Middle Ages. The practice, sometimes used by miners and fortune seekers, was reportedly condemned in the 16th century as the work of the devil.

Today, dowsers hail from one of two camps. Some have agrarian backgrounds, and learned the practice from ancestors who used it to locate good sites for wells on their own or their neighbors’ farms. The second group hails from the New Age movement and tend to be devotees of a wide range of mystical practices and “energy work”.

Traditionally, dowsing has been used not just to find groundwater, but also minerals and natural gas. Many dowsers claim they can dowse anything, from lost items or pets to criminals on the lam. You name it, they say they can divine it.

Hope began dowsing for water in 1977 after learning about the practice from Walter Woods, a science teacher at Butte College, where she was a STUDENT. Woods had learned dowsing from his father, a farmer, and eventually became a well-known authority on dowsing. He authored a widely read dowsing primer, Letter to Robin, and served as president of the American Society of Dowsers.

Woods taught Hope to scan for signs of groundwater by observing the landscape and looking for signs like deer trails. “Deer have magnetite in their pineal gland [an endocrine gland in the brain]. As water moves underground, electrons are stripped out and move to the surface,” Hope says. “Deer can sense it and tend to walk along that vein of underground water toward a spring.” Dowsing is based on the premise that humans can tap into that energy, too, using instruments such as branches and pendulums.

Energy marks the spot

After Hope finishes with the map, she heads out to the spots she has marked, walking the land and searching for very faint energy markings over the landscape, which she’ll use more talismans to locate.

She begins a general scan of the area with a forked pine branch, holding the ends in her hands and sweeping it through the air. Despite scientific evidence, Hope believes that the branch she holds channels the energy emitted by submerged water. Once she homes in on the most promising region (which matches, as it turns out, the area she had marked on the map) she TRADES the branch for what are known in the dowsing world as “L-rods”, two long metal bars with a short handle and long extension, forming an L.

Hope holds these in front of her, with her elbows at 90 degrees, and walks slowly up – and then laterally along – the rise. As the long ends of the bars begin to fall away from each other, she stops.

The energy moving up from the groundwater, she says, creates a field that L-rods respond to. This, she says, marks the edge of the underground stream. She then traverses the hillside, down slope, and stops again when the bars cross in front of her. This, she explains, marks the spot where two veins of groundwater cross over each other, making it a potentially very productive well site.

“I have goosebumps,” Hope says with a smile. “I feel the energy moving up from the ground.”

Although Hope and other dowsers often refer to underground veins and streams, USGS hydrologist Ralph Health, in a highly cited report on groundwater basics, says the vast majority of groundwater is found in relatively still aquifers. Swiftly moving streams are quite rare.

Water, water everywhere

Out in the field, Hope locates three possible well sites in roughly 30 minutes. She decides that the third is the best option, even though she doesn’t think it has the strongest flow rate, because it is relatively shallow at 200 feet (about 61 meters) below ground and is the most accessible and FLAT option. Daley stakes the spot and the dowsing is done. Daley is now awaiting drilling permits, and once those come through, she’ll call in a local driller.

“I have about 90% accuracy,” Hope claims, meaning that 90% of the sites she recommends produce water.

This actually isn’t that surprising, hydrogeologists say. “Dowsers may seem convincing, but when [their practice is] exposed to scientific review, groundwater is very prevalent, so it’s hard to miss it when you drill a well,” says Ted Johnson, chief hydrogeologist for the Water Replenishment District of Southern California and president of the board of the Groundwater Resources Association of California. “When you use science to site a well, you can test for quality, depth and how long [the flow] will last.”

To site a well, hydrogeologists will review driller well logs from the Department of Water Resources and geologic maps that show areas of alluvial soils, under which groundwater is most likely to accumulate. To really zero in on well sites, they drill a test well, which produces cuttings of the various strata. They then test for each layer’s ability to transport water. It’s a time-consuming and expensive process.

Because a landowner is unlikely to hire both a dowser and a hydrogeologist to see who finds the best-producing well (though that could make for some mildly entertaining reality television), the two groups coexist and generally ignore each other, aside from tossing verbal jabs.

“I’m a scientist and I’ve been trained on scientific principles, and that’s what I use [to locate groundwater],” says Tim Parker, a hydrogeologist and independent consultant based in Sacramento. “There’s no scientific evidence that dowsing is more effective than random chance.”

Of cash and crops

So why are so many farmers turning to dowsers instead of hydrologists? Part of it’s probably the money: dowsers might charge $1,000 (Hope charges most of her clients around $500, and less for a small residential well), while a big consulting firm costs $10,000 to $50,000, Johnson says. “All a farmer cares about is getting the groundwater,” he says.

But Cynthia Daley, who hired Sharron Hope to dowse for a well on her dairy farm, says it’s not about costs. “Dowsing is based on energy and it is something that the scientific community has not embraced, but I’m not arrogant enough to think science knows everything – and I am a scientist; I have a PhD,” she says.

Whether farmers and vintners are using dowsers merely as a result of their relative affordability or out of a strong belief in the practice is hard to, well, divine. What is clear is that the popularity of dowsing is growing, not just in the CENTRAL VALLEY, but throughout the state.

Daley, who has degrees in animal science with a doctorate in endocrinology, is a professor in the College of Agriculture at nearby California State University at Chico, where she runs an organic dairy program. She is developing an organic dairy operation on her property, which is why she’s drilling wells. “Everyone I know who has had wells put in around here has used dowsers.”

Many more wells are springing up. State agencies from counties around California are issuing twice – and sometimes three times as many – well drilling permits this summer than last summer, according to the Associated Press.

Keeping Marc Mondavi busy

Marc Mondavi, grandson of Napa Valley WINE pioneer Cesare Mondavi and a longtime dowser, says that he can’t keep up with the demand: “I’m doing anywhere from two to four projects a week and I’m backlogged, and drillers around here are backlogged for three to five months.”

Mondavi uses dowsing not only as a revenue stream, but also as a means of marketing his own brand, The Divining Rod. He doesn’t shy away from the name “water witch”, a term other dowsers consider pejorative. His daughter Alycia Mondavi even made a short promo VIDEO CALLED “My Dad is a Witch.”

He acknowledges it’s hard not to strike groundwater, but says that using his intuitive dowsing skills allows him to find the best spots, especially as the drought depletes the water table. “No matter where you drill, you might hit [a flow of] four gallons per minute,” he says. “In those areas maybe I can find eight to 10 gallons per minute.”

The dowsing divide might persist for decades to come, but there is plenty of indisputable evidence that groundwater is being overtaxed as the drought drags on. Amplifying the problem of groundwater scarcity, policy experts say, is a lack of regulation. That looks likely to change. Governor Brown is expected to sign one of three separate groundwater regulation bills currently sitting on his desk.

Some agriculture groups, including the Agriculture Council of California and Blue Diamond Growers, have rallied against the bills, saying they will drive up costs for already cash-strapped farmers and deny long-held water rights.

But Daley says groundwater is too important to remain unchecked. “We have to regulate it. It’s a very important resource.”

5 razões para assistir à Cúpula do Clima de Nova York (Portal do Meio Ambiente)

PUBLICADO 18 SETEMBRO 2014

No próximo dia 23 de setembro, chefes de estado e líderes do sistema financeiro, de empresas e da sociedade civil se reunirão em Nova York na Cúpula do Clima das Nações Unidas de 2014. A reunião será um marco importante no caminho de enfrentamento da crise climática. O Secretário-geral da ONU, Ban Ki-moon, convocou a Cúpula de alto nível para reengajar os líderes mundiais e estimular a ação pelo clima nos níveis nacionais e internacional.

Dezenas de milhares de cidadãos interessados estão aproveitando a oportunidade para organizar a maior marcha pelo clima da história. Durante a semana da Cúpula centenas de organizações organizarão palestras, exibições de cinema documental e outros encontros para apresentar evidências esmagadoras das consequências das alterações climáticas e soluções custo-efetivas para resolver o problema. Novos estudos científicos como a Avaliação Nacional do Clima dos EUA e os últimos relatórios do IPCC iluminaram os riscos de poluição da atmosfera pelo carbono, enquanto novas análises econômicas, incluindo próximo relatório Nova Economia do Clima, do World Resources Institute, devem dissipar a noção de que a ação pelo clima desacelerará o crescimento econômico.

No entanto, esta não é a primeira vez que os governos são convocados para combater as mudanças climáticas. Então, por que vale a pena assistir a esta Cúpula? Aqui estão os porquês:

1) É a primeira vez em cinco anos na qual chefes de estado se reunirão para enfrentar a mudança climática

Esta será a primeira vez em cinco anos – desde as negociações de Copenhague de 2009 – que tantos líderes mundiais se reunirão para discutir a mudança climática. O Secretário-Geral Ban Ki-moon chamou a Cúpula para dar o pontapé inicial de um período de 15 meses de intenso engajamento e negociação pelo clima como tentativa de obter um acordo global em dezembro de 2015. Criar uma boa dinâmica em Nova York será extremamente importante para alcançar esse objetivo.

2) Obama e Xi estarão lá**

Tanto o presidente dos EUA, Barack Obama quanto o presidente chinês, Xi Jinping, líderes dos dois países que mais emitem gases de efeito estufa, participarão da cúpula. Se medidas substantivas de redução das emissões devem ser implantadas, tanto os EUA quanto a China deverão se envolver completamente. É encorajador que os dois países já estejam colaborando em projetos de energia limpa nos níveis de pesquisa, de governo e empresarial por meio de iniciativas como os Centro de Pesquisa de Energia Limpa EUA-China (CERC). Em julho os dois países revelaram oito novos acordos de parceria climática. A presença desses chefes de estado na Cúpula oferece uma oportunidade de continuidade da cooperação.

3) Novas vozes que clamam por maior ação

A maioria dos atuais líderes ainda não estava no poder em 2009, quando da Cúpula de Copenhague. Muitos destes falam abertamente sobre a ameaça que a mudança climática representa para seus países, bem como sobre as oportunidades econômicas que se abrem com a perspectiva de economia de baixo carbono. Estas novas vozes vêm de países de renda média como Chile, Colômbia, Costa Rica e Indonésia onde os governos estão implantando políticas climáticas ambiciosas ou manifestam vontade de fazê-lo. Suas novas visões devem moldar as discussões da cúpula de alto nível.

Também se espera que os países mais pobres apresentem seus desafios e suas contribuições para a solução do problema.

4) Novos compromissos de países, cidades e do setor privado

A Cúpula de um dia será um fórum para a troca de iniciativas entre os países. Durante a manhã acontecerão três sessões simultâneas nas quais os países devem anunciar suas medidas de combate às mudanças climáticas. Os anúncios provavelmente variarão de compromissos de capitalização do Fundo Verde para o Clima, como a contribuição de US$ 1 bilhão feita recentemente pela Alemanha como ajuda aos demais países para sua preparação para os impactos do clima e busca de caminhos de baixo carbono, até ações internas como de alteração de matrizes energéticas desde o carvão às energias renováveis de grande escala.

Os líderes mundiais também podem usar a reunião para se comprometerem a apresentar um rascunho de seus planos climáticos pós-2020 até o mês de março de 2015 (processo conhecido no jargão das negociações como “contribuições intencionais nacionais determinadas” ou INDCs na sigla em inglês) – de modo a incentivar seus colegas a também fazê-lo. O respeito a esse prazo dará aos ‘stakeholders’ nacionais e internacionais a oportunidade de responder e sugerir melhorias antes dos países apresentarem suas propostas definitivas nove meses depois, em Paris.

Finalmente, o encontro oferece uma plataforma para a apresentação de novas e significativas ideias pelos líderes do setor privado e das cidades. Prepare-se para conhecer novos esforços privados e/ou públicos em matéria de energia, cidades de baixo carbono, restauração florestal, transporte, agricultura, finanças e resiliência. Estas novas iniciativas complementarão as ações nacionais envolvendo todos os níveis da sociedade no esforço global para o enfrentamento do problema.

5) A transição global para a energia limpa está remodelando a paisagem da política

A rápida adoção de energias renováveis nos últimos anos mudou o que era considerado viável há apenas cinco anos. Os custos de produção da energia solar caíram 80% e a energia eólica nunca foi tão acessível. Em outubro passado, a Dinamarca produziu mais energia a partir dos ventos do que o total consumido pelo país. A China estabeleceu metas agressivas para energias renováveis para os anos de 2015, 2017 e 2020. Mais e mais empresas elétricas norte americanas estão descobrindo que o vento e o Sol oferecem a forma mais barata para adicionar capacidade de geração adicional. E cerca de 100 países em desenvolvimento têm agora estabelecidas políticas para energia renováveis. O panorama energético em mudança e os fortes benefícios sociais e econômicos da transição para a energia limpa dão argumentos fortes aos líderes dos países e das empresas pela liderança climática.

Uma chance para que os líderes mundiais se comprometam pela ação climática

A Cúpula será um prenúncio para o compromisso dos chefes de estado quanto ao enfrentamento da crise climática no período que leva a Paris e além. Fortes e claros compromissos elevariam a mudança climática na agenda global e preparariam o terreno para o progresso nacional e internacional.

Durante uma reunião de alto nível em Abu Dhabi em maio deste ano, Ban Ki-moon exortou os participantes a “capacitar e motivar os seus líderes nacionais para que tragam anúncios ousados à Cúpula do Clima de setembro… A corrida começou. É hora de liderar”. Em poucas semanas veremos se os líderes estão à altura do desafio.

The ‘Wall Street Journal’ Parade of Climate Lies (Huff Post)

Posted: 09/06/2014 8:21 am EDT Updated: 09/07/2014 10:59 pm EDT

RUPERT MURDOCH

That Rupert Murdoch governs over a criminal media empire has been made clear enough in the UK courts in recent years. That the Wall Street Journal op-ed pages, the latest victim of Murdoch’s lawless greed, are little more than naked propaganda is perhaps less appreciated. The Journal runs one absurd op-ed after another purporting to unmask climate change science, but only succeeds in unmasking the crudeness and ignorance of Murdoch’s henchmen. Yesterday’s (September 5) op-edby Matt Ridley is a case in point.

Ridley’s “smoking gun” is a paper last week in Science Magazine by two scientists Xianyao Chen and Ka-Kit Tung, which Ridley somehow believes refutes all previous climate science. Ridley quotes a sentence fragment from the press release suggesting that roughly half of the global warming in the last three decades of the past century (1970-2000) was due to global warming and half to a natural Atlantic Ocean cycle. He then states that “the man-made warming of the past 20 years has been so feeble that a shifting current in one ocean was enough to wipe it out altogether,” and “That to put the icing on the case of good news, Xianyao Chen and Ka-Kit Tung think the Atlantic Ocean may continue to prevent any warming for the next two decades.”

The Wall Street Journal editors don’t give a hoot about the nonsense they publish if it serves their cause of fighting measures to limit human-induced climate change. If they had simply gone online to read the actual paper, they would have found that the paper’s conclusions are the very opposite of Ridley’s.

First, the paper makes perfectly clear that the Earth is warming in line with standard climate science, and that the Earth’s warming is unabated in recent years. In the scientific lingo of the paper (it’s very first line, so Ridley didn’t have far to read!), “Increasing anthropogenic greenhouse-gas-emissions perturb Earth’s radiative equilibrium, leading to a persistent imbalance at the top of the atmosphere (TOA) despite some long-wave radiative adjustment.” In short, we humans are filling the atmosphere with carbon dioxide from fossil-fuel use, and we are warming the planet.

Second, the total warming is distributed between the land and ocean surface on the one hand and the ocean deep water on the other. The total rise of ocean heat content has continued unabated, while the proportion of heat absorbed at the surface and in the deeper ocean varies over time. Again, in the scientific lingo of the paper, “[T]his forced total OHC [ocean heat content] should be increasing monotonically over longer periods even through the current period of slowed warming. In fact, that expectation is verified by observation …”. In other words, the ocean has continued to warm in line with predictions of just such a phenomenon seen in climate models.

Third, it is the “vertical distribution” of the warming, between the surface and deep water, which affects the warming observed on land and at the sea surface. The point of the paper is that the allocation of the warming vertically varies over time, sometimes warming the surface rapidly, other times warming the deeper ocean to a great extent and the surface water less rapidly. According to the paper, the period of the late 20th century was a period in which the surface was warmed relative to the deeper ocean. The period since 2000 is the opposite, with more warming of the deeper ocean. How do the scientists know? They measure the ocean temperature at varying depths with a sophisticated system of “Argo profiling floats,” which periodically dive into the ocean depths to take temperature readings and resurface to transmit them to the data centers.

So, what is Ridley’s “smoking gun” when you strip away his absurd version of the paper? It goes like this. The Earth is continuing to warm just as greenhouse gas theory holds. The warming heats the land and the ocean. The ocean distributes some of the warming to the surface waters and some to the deeper waters, depending on the complex circulation of ocean waters. The shares of warming of the surface and deeper ocean vary over time, in fluctuations that can last a few years or a few decades.

If the surface warming is somewhat less in recent years than in the last part of the 20th century, is that reason for complacency? Hardly. The warming is continuing, and the consequences of our current trajectory will be devastating unless greenhouse gas emissions (mainly carbon dioxide) are stopped during this century. As Chen and Tung conclude in their Science paper, “When the internal variability [of the ocean] that is responsible for the current hiatus [in warming] switches sign, as it inevitably will, another episode of accelerated global warming should ensue.”

Mr. Murdoch, and the Wall Street Journal, can it be any clearer than this?

The Wall Street Journal downplays global warming risks once again (The Guardian)

Monday 22 September 2014 14.00 BST

The periodical follows the Murdoch media pattern of sowing doubt about climate change threats

As has become the norm for media outlets owned by Rupert Murdoch, just before a half million people participated in the People’s Climate Marcharound the world, The Wall Street Journal published an opinion piece downplaying the risks and threats posed by human-caused global warming. The editorial was written by Steven Koonin, a respected computational physicist who claims to have engaged in “Detailed technical discussions during the past year with leading climate scientists,” but who is himself not a climate scientist.

Koonin did admit that the climate is changing and humans are largely responsible, and noted,

There is well-justified prudence in accelerating the development of low-emissions technologies and in cost-effective energy-efficiency measures.

This is a step in the right direction. Unfortunately, Koonin’s editorial focused almost exclusively on the remaining uncertainties in climate science. Ironically, he stated,

Any serious discussion of the changing climate must begin by acknowledging not only the scientific certainties but also the uncertainties, especially in projecting the future.

But Koonin himself got the certainties wrong. For example, we know that humans are the main cause of the current climate change, responsible for about 100% of the global warming since 1950. However, Koonin’s editorial claimed,

The impact today of human activity appears to be comparable to the intrinsic, natural variability of the climate system itself.

This is simply incorrect. As climate scientist Michael Mann told Climate Science Watch in their thorough response to Koonin’s piece,

The fact is that the actual peer-reviewed scientific research shows that (a) the rate of warming over the past century is unprecedented as far back as the 20,000 years paleoclimate scientists are able to extend the record and (b) that warming can ONLY be explained by human influences.

Indeed, it is the RATE of warming that presents such risk to human civilization and our environment.

Climate scientists Michael Oppenheimer and Kevin Trenberth also took issue with Koonin’s assertion about the impact of human activity, saying,

Warming is well beyond natural climate variability and projected rates of change are potentially faster than ecosystems, farmers and societies can adapt to without major disruptions. Many details remain to be settled, and weather and natural variability will always mask some effects, especially regionally. But economic analysis of these risks supports substantial action beyond “no regrets” strategies. To argue otherwise as Koonin does is to ignore decades of research results.

Koonin primarily focused on the uncertainty in the specific impacts of continued rapid global warming. However, he glossed over the fact that those uncertainties range from generally bad impacts to potentially catastrophic impacts. Even in a best case scenario, climate science research indicates that we anticipate experiencing widespread coral mortality, hundreds of millions of people at risk of increased water stress, more damage from droughts and heat waves and floods, up to 30% of global species at risk for extinction, and declined global food production, for example.

Those are the anticipated impacts if we limit global warming to not much above 2°C warming as compared to pre-industrial levels. Accomplishing that would require intensive efforts to reduce human greenhouse gas emissions, and if we fail, the consequence will be far worse.

The good news is that slowing global warming can be accomplished with minimal economic impact. In fact, economic research consistently shows that reducing greenhouse gas emissions, if done right, is far cheaper than paying for the damages caused by unabated climate change. For example, a revenue-neutral carbon tax could create jobs and grow the economy. Two recent studies by the New Climate Economy Project and the International Monetary Fund likewise found that reducing carbon pollution could grow the economy, as summarized by The Guardian.

As Koonin noted in his piece, risk management is key in determining how to respond to the threats posed by climate change. On the one hand, we have a threat to the entire global climate on which every species on Earth relies, which humans are in the process of destabilizing at a rate more rapid than many species can adapt.

On the other hand, we have concerns about the impacts of climate policy on the economy. However, numerous studies have found that if done right, those policies can grow the economy, and will certainly be cheaper than paying for the damages of unabated climate change.

While uncertainties remain about whether the impacts of climate change will be bad, catastrophic, or somewhere in between, that’s precisely the kind of scenario in which uncertainty is not our friend. When faced with a risk to something so important, humans are usually smart enough to take action to manage that risk. For example, we buy home insurance, we wear seat belts, and fewer people now smoke than in previous generations who were unaware of the associated risks.

It’s critical to grasp not just that there are uncertainties about the impacts of climate change, but what those uncertainties tell us about the range of potential outcomes. It’s easy to simply say “the impacts are uncertain,” but when those uncertainties range from bad to catastrophic, taking action to mitigate the threat is a no-brainer. Additionally, larger uncertainty means that we can’t rule out the most catastrophic potential impacts, and actually makes the case for taking action stronger, as a study published earlier this year showed.

The bottom line is that while there are and always will be uncertainties in climate science that require further research, it’s already been several decades since we’ve understood climate change well enough to justify taking serious action to solve the problem. The longer we wait, the costlier those actions become, and the worse the impacts of human-caused global warming will be. The hundreds of thousands of people who marched yesterday understand that, but the Murdoch media hasn’t caught up yet.

The Most Terrifying Thing About Ebola (Slate)

The disease threatens humanity by preying on humanity.

As the Ebola epidemic in West Africa has spiraled out of control, affecting thousands of Liberians, Sierra Leonians, and Guineans, and threatening thousands more, the world’s reaction has been glacially, lethally slow. Only in the past few weeks have heads of state begun to take serious notice. To date, the virus has killed more than 2,600 people. This is a comparatively small number when measured against much more established diseases such as malaria,HIV/AIDS, influenza, and so on, but several factors about this outbreak have some of the world’s top health professionals gravely concerned:

  • Its kill rate: In this particular outbreak, a running tabulation suggests that 54 percent of the infected die, though adjusted numbers suggest that the rate is much higher.
  • Its exponential growth: At this point, the number of people infected is doubling approximately every three weeks, leading some epidemiologists to projectbetween 77,000 and 277,000 cases by the end of 2014.
  • The gruesomeness with which it kills: by hijacking cells and migrating throughout the body to affect all organs, causing victims to bleed profusely.
  • The ease with which it is transmitted: through contact with bodily fluids, including sweat, tears, saliva, blood, urine, semen, etc., including objects that have come in contact with bodily fluids (such as bed sheets, clothing, and needles) and corpses.
  • The threat of mutation: Prominent figures have expressed serious concerns that this disease will go airborne, and there are many other mechanisms through which mutation might make it much more transmissible.

Terrifying as these factors are, it is not clear to me that any of them capture what is truly, horribly tragic about this disease.

The most striking thing about the virus is the way in which it propagates. True, through bodily fluids, but to suggest as much is to ignore the conditions under which bodily contact occurs. Instead, the mechanism Ebola exploits is far more insidious. This virus preys on care and love, piggybacking on the deepest, most distinctively human virtues. Affected parties are almost all medical professionals and family members, snared by Ebola while in the business of caring for their fellow humans. More strikingly, 75 percent of Ebola victims are women, people who do much of the care work throughout Africa and the rest of the world. In short, Ebola parasitizes our humanity.

More than most other pandemic diseases (malaria, cholera, plague, etc.) and more than airborne diseases (influenza, swine flu, H5N1, etc.) that are transmitted indiscriminately through the air, this disease is passed through very minute amounts of bodily fluid. Just a slip of contact with the infected party and the caregiver herself can be stricken.

The images coming from Africa are chilling. Little boys, left alone in the street without parents, shivering and sick, untouchable by the throngs of people around them. Grown men, writhing at the door to a hospital, hoping for care as their parents stand helplessly, wondering how to help. Mothers and fathers, fighting weakness and exhaustion to move to the edge of a tent in order to catch a distant, final glimpse of a get-well video that their children have made for them.

If Ebola is not stopped, this disease can destroy whole families within a month, relatives of those families shortly thereafter, friends of those relatives after that, and on and on. As it takes hold (and it is taking hold fast), it cuts out the heart of family and civilization. More than the profuse bleeding and high kill rate, this is why the disease is terrifying. Ebola sunders the bonds that make us human.

Aid providers are now working fastidiously to sever these ties themselves, fighting hopelessly against the natural inclinations that people have to love and care for the ill. They have launched aggressive public information campaigns, distributedupdates widely, called for more equipment and gear, summoned the military, tried to rein in the hysteria, and so on. Yet no sheet of plastic or latex can disrupt these human inclinations.

Such heroic efforts are the appropriate medical response to a virulent public health catastrophe. The public health community is doing an incredible job, facing unbelievable risks, relying on extremely limited resources. Yet these efforts can only do half of the work. Infected parties—not all, to be sure, but some (enough)—cannot abide by the rules of disease isolation. Some will act without donning protective clothing. Some will assist without taking proper measures. And still others will refuse to enter isolation units because doing so means leaving their families and their loved ones behind, abandoning their humanity, and subjecting themselves to the terror of dying a sterile, lonely death.

It is tempting, at these times, to focus on the absurd and senseless actions of a few. One of the primary vectors in Sierra Leone is believed to have been a traditional healer who had been telling people that she could cure Ebola. In Monrovia a few weeks back, angry citizens stormed a clinic and removed patients from their care. “There is no Ebola!” they are reported to have been shouting. More recently, the largest newspaper in Liberia published an article suggesting that Ebola is a conspiracy of the United States, aimed to undermine Africa. And, perhaps even more sadly, a team of health workers and journalists was just brutally murdered in Guinea. It is easy, in other words, to blame the spread on stupidity, or illiteracy, or ritualism, or conspiracy theories, or any number of other irrational factors.

But imagine: You are a parent whose child has suddenly come ill with a fever. Do you cast your child away and refuse to touch him? Do you cover your face and your arms? Stay back! Unclean! Or do you comfort your child when he asks for you, arms outstretched, to make the pain go away?

Imagine: You live in a home with five other family members. Your sister falls ill, ostensibly from Ebola, but possibly from malaria, typhoid, yellow fever, or the flu. You are aware of the danger to yourself and your other family members, but you have no simple means to move her, and she is too weak to move herself. What do you do?

Imagine: You are a child of 5 years old. Your mother is sick. She implores you to back away. But you are scared. What you need, more than anything, is a hug and a cry.

Who can blame a person for this? It is a terrible, awful predicament. A moral predicament. To stay, comfort, and give love and care to those who are in desperate need, or to shuttle them off into an isolation ward, perhaps never to see them again? What an inhumane decision this is.

What makes the Ebola virus so terrifying is not its kill rate, its exponential growth, the gruesome way in which it kills, the ease of transmission, or the threat of mutation, but rather that people who care can do almost nothing but sit on the sidelines and watch.

* * *

Many have asked whether Ebola could come here, come West. (The implication, in its way, is crass—as if to suggest that we need not be concerned about a tragedy unless it poses a threat to us.) We have been reassured that it will never spread widely here, because our public health networks are too strong, our hospitals too well-stocked. The naysayers may be right about this. But they are not right that it does not pose a threat to us.

For starters, despite the pretense, the West is not immune from absurd, unscientific thinking. We have our fair share of scientific illiteracy, skepticism, ritualism, and foolishness. But beyond this, it is our similarities, not our differences, that make us vulnerable to this plague. We are human. Every mechanism we have for caring—touching, holding, feeding, playing, warming, comforting, caressing—every mechanism that we use to bind us to our families and our neighbors, is preyed upon by Ebola. We cannot seal each other into hyperbaric chambers and expect that once we emerge, the carnage will be over. We are humans, and we will care about our children and our families even if it means that we may die in doing so.

The lesson here is a vital one: People do not give up on humanity so very easily. Even if we persuade all of the population to forgo rituals like washing the dead, we will not easily persuade parents to keep from holding their sick children, children from clinging to their ailing parents, or children from playing and wrestling and slobbering all over one another. We tried to alter such behaviors with HIV/AIDS. A seemingly simple edict—“just lay off the sex with infected parties”—would seem all that is required to halt that disease. But we have learned over the decades that people do not give up sex so readily.

If you think curtailing sex is hard, love and compassion will be that much harder. Humans will never give this up—we cannot give this up, for it is fundamental to who we are. The more that medical personnel require this of people without also giving them methods to manifest care, the more care and compassion will manifest in pockets outside of quarantine. And the more humanity that manifests unchecked, the more space this virus has to grow. Unchecked humanity will seep through the cracks and barriers that we build to keep our families safe, and if left to find its own way, will carry a lethal payload.

The problem is double-edged. Ebola threatens humanity by preying on humanity. The seemingly simple solution is to destroy humanity ourselves—to seal everything off and let the disease burn out on its own. But doing so means destroying ourselves in order to save ourselves, which is no solution at all.

We must find a method of caring without touching, of contacting without making contact. The physiological barriers are, for the time being, necessary. But we cannot stop people from caring about one another, so we must create, for the time being, mechanisms for caring. Since we will never be able to beat back humanity, we must coordinate humanity, at the family level, the local level, and the global level.

The only one way to battle a disease that affixes itself parasitically to our humanity is to overwhelm it with greater, stronger humanity. To immunize Africa and the rest of the world with a blast of humanity so powerful that the disease can no longer take root. What it will take to beat this virus is to turn its most powerful vehicle, our most powerful weapon, against it.

Here are some things we can do:

Donate to the great organizations that are working tirelessly to bring this disease under control. They need volunteers, medical supplies, facilities, transportation, food, etc. Share information about Ebola, so people will learn about it, know about it, and know how to address it when it comes. And inform and help others. It is natural at a time of crisis to call for sealing the borders, to build fences and walls that separate us further from outside threats. But a disease that infects humanity cannot easily be walled off in this way. Walling off just creates unprotected pockets of humanity, divisions between us and them: my family, your family; that village, this village; inside, outside.

* * *

One final thing.

When Prince Prospero, ill-fated protagonist of Edgar Allan Poe’s story “The Masque of the Red Death,” locked himself in his castle to avoid a contagion that was sweeping his country—a disease that caused “profuse bleeding at the pores”—he assumed mistakenly that the only reasonable solution to his problem was to remove himself from the scene. For months he lived lavishly, surrounded by courtiers, improvisatori, buffoons, musicians, and wine, removed from danger while the pestilence wrought havoc outside.

As with much of Poe’s writing, Prospero’s tale does not end well. For six months, all was calm. He and his courtiers enjoyed their lives, secure and isolated from the plague laying waste to the countryside. Then, one night during a masquerade ball, the Red Death snuck into the castle, hidden behind a mask and a cloak, to afflict Prospero and his revelers, dropping them one by one in the “blood-bedewed halls.” Prospero’s security was a façade, leaving darkness and decay to hold “illimitable dominion over all.” The eventual intrusion that would be his undoing foretells of a danger in believing that we can keep the world’s ills at bay by keeping our distance.

If we seek safety by shutting out the rest of the world, we are in for a brutally ugly awakening. Nature is a cruel mistress, but Ebola is her cruelest, most devious trick yet.

Saving Native Languages and Culture in Mexico With Computer Games (Indian Country)

Thinkstock

9/21/14

Indigenous children in Mexico can now learn their mother tongues with specialized computer games, helping to prevent the further loss of those languages across the country.

“Three years ago, before we employed these materials, we were on the verge of seeing our children lose our Native languages,” asserted Matilde Hernandez, a teacher in Zitacuaro, Michoacan.

“Now they are speaking and singing in Mazahua as if that had never happened,” Hernandez said, referring to computer software that provides games and lessons in most of the linguistic families of the country including Mazahua, Chinanteco, Nahuatl of Puebla, Tzeltal, Mixteco, Zapateco, Chatino and others.

The new software was created by scientists and educators in two research institutions in Mexico: the Victor Franco Language and Culture Lab (VFLCL) of the Center for Investigations and Higher Studies in Social Anthropology (CIHSSA); and the Computer Center of the National Institute of Astrophysics, Optics and Electronics (NIAOE).

According to reports released this summer, the software was developed as a tool to help counteract the educational lag in indigenous communities and to employ these educational technologies so that the children may learn various subjects in an entertaining manner while reinforcing their Native language and culture.

“This software – divided into three methodologies for three different groups of applications – was made by dedicated researchers who have experience with Indigenous Peoples,” said Dr. Frida Villavicencio, Coordinator of the VLFCL’s Language Lab.

“We must have an impact on the children,” she continued, “offering them better methodologies for learning their mother tongues, as well as for learning Spanish and for supporting their basic education in a fun way.”

Villavicencio pointed out that the games and programs were not translated from the Spanish but were developed in the Native languages with the help of Native speakers. She added that studies from Mexico’s National Institute of Indigenous Languages (NIIL) show that the main reason why indigenous languages disappear, or are in danger of doing so, is because in each generation fewer and fewer of the children speak those languages.

“We need bilingual children only in that way can we preserve their languages,” she added.

Vira-latas sob controle (Fapesp)

22 de setembro de 2014

Por Yuri Vasconcelos

Software estima a população de cães e gatos abandonados e simula estratégias que beneficiam a saúde animal e humana (foto: Wikimedia)

Revista Pesquisa FAPESP – Ninguém conhece ao certo o tamanho das populações canina ou felina no Brasil, sejam elas de animais supervisionados – que têm dono e vivem em domicílios – ou de rua.

A caracterização demográfica de cães e gatos é um passo importante para definir estratégias de manejo populacional desses animais, além de contribuir para o controle de zoonoses como a raiva e a leishmaniose visceral, que causam 55 mil mortes e 500 mil casos no mundo, respectivamente.

Para lidar melhor com esse problema, um grupo de pesquisadores da Faculdade de Medicina Veterinária (FMVZ) da Universidade de São Paulo (USP), na capital paulista, criou um software capaz de estimar com elevado índice de precisão quantos cães e gatos domiciliados vivem nas cidades brasileiras.

“Conhecer a população de rua é essencial. Ela é resultado do abandono de animais”, diz o médico veterinário Fernando Ferreira, professor e coordenador do programa de pós-graduação da FMVZ.

O Brasil lidera a incidência de leishmaniose visceral na América Latina com cerca de 3 mil infectados por ano, o que representa 90% do total do continente. A raiva, apesar de poder ser controlada com vacinação, ainda tem casos no país. Em 1990, foram 50 casos em humanos, situação que variou de zero a dois casos entre 2007 e 2013.

Animais abandonados representam um problema de saúde pública, porque são os principais reservatórios e transmissores dessas enfermidades. Ao mesmo tempo, esses animais são vítimas de atropelamentos, abusos e crueldade.

A técnica mais confiável para dimensionar e classificar a população canina de rua foi criada pelo Instituto Pasteur em 2002 e indica que esses animais representam cerca de 5% dos indivíduos que têm dono.

“Assim, sabendo quantos cães supervisionados vivem numa determinada região, é possível estimar quantos existem nas ruas desse mesmo lugar”, diz Ferreira. “Já que existe uma relação direta entre essas duas populações, as estratégias de controle de cães abandonados passam pelo controle reprodutivo dos animais domiciliados”, explica o pesquisador, que contou no projeto com a colaboração do professor Marcos Amaku, também da FMVZ.

Batizado com a sigla capm – iniciais em inglês de companion animal population management ou manejo populacional de cães e gatos –, o software foi desenvolvido pelo doutorando Oswaldo Santos Baquero, bolsista da FAPESP.

“No meu estudo, avalio a validade de um desenho amostral complexo para estimar o tamanho populacional de cães domiciliados em municípios brasileiros. Também elaborei um modelo matemático de dinâmica populacional para simular cenários e definir prioridades de intervenção”, conta Baquero.

Para ele, a partir da modelagem matemática é possível, por exemplo, compreender com mais facilidade que o principal efeito esperado da esterilização é o aumento da população infértil e não a diminuição do tamanho de uma população inteira.

“Modelos matemáticos da transmissão da raiva na China sugerem que a melhor forma de controlar a doença é reduzir a taxa de natalidade canina e aumentar a imunização. Essas duas ações combinadas mostraram-se mais efetivas do que o sacrifício de animais.”

Dogs can be pessimists, too (Science Daily)

Summary: Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that most would have an optimistic outlook on life. In fact some dogs are distinctly more pessimistic than others, new research shows.

Dogs generally seem to be cheerful, happy-go-lucky characters, so you might expect that most would have an optimistic outlook on life.

In fact some dogs are distinctly more pessimistic than others, research from the University of Sydney shows.

“This research is exciting because it measures positive and negative emotional states in dogs objectively and non-invasively. It offers researchers and dog owners an insight into the outlook of dogs and how that changes,” said Dr Melissa Starling, from the Faculty of Veterinary Science. Her PhD research findings are published in PLOS One today.

“Finding out as accurately as possible whether a particular dog is optimistic or pessimistic is particularly helpful in the context of working and service dogs and has important implications for animal welfare.”

Dogs were taught to associate two different sounds (two octaves apart) with whether they would get the preferred reward of milk or instead get the same amount of water. Once the dogs have learnt the discrimination task, they are presented with ‘ambiguous’ tones.

If dogs respond after ambiguous tones, it shows that they expect good things will happen to them, and they are called optimistic. They can show how optimistic they are by which tones they respond to. A very optimistic dog may even respond to tones that sound more like those played before water is offered.

“Of the dogs we tested we found more were optimistic than pessimistic but it is too early to say if that is true of the general dog population,” said Dr Starling.

However it does mean that both individuals and institutions (kennels, dog minders) can have a much more accurate insight into the emotional make-up of their dogs.

According to the research a dog with an optimistic personality expects more good things to happen, and less bad things. She will take risks and gain access to rewards. She is a dog that picks herself up when things don’t go her way, and tries again. Minor setbacks don’t bother her.

If your dog has a pessimistic personality, he expects less good things to happen and more bad things. This may make him cautious and risk averse. He may readily give up when things don’t go his way, because minor setbacks distress him. He may not be unhappy per se, but he is likely to be most content with the status quo and need some encouragement to try new things.

“Pessimistic dogs appeared to be much more stressed by failing a task than optimistic dogs. They would whine and pace and avoid repeating the task while the optimistic dogs would appear unfazed and continue,” said Dr Starling.

“This research could help working dog trainers select dogs best suited to working roles. If we knew how optimistic or pessimistic the best candidates for a working role are, we could test dogs’ optimism early and identify good candidates for training for that role. A pessimistic dog that avoids risks would be better as a guide dog while an optimistic, persistent dog would be more suited to detecting drugs or explosives.”

Dr Starling has been working with Assistance Dogs Australia, a charity organisation that provides service and companion dogs to people with disabilities, to investigate whether an optimism measure could aid in selecting suitable candidates for training.

The research not only suggests how personality may affect the way dogs see the world and how they behave but how positive or negative their current mood is.

“This research has the potential to completely remodel how animal welfare is assessed. If we know how optimistic or pessimistic an animal usually is, it’s possible to track changes in that optimism that will indicate when it is in a more positive or negative emotional state than usual,” said Dr Starling.

“The remarkable power of this is the opportunity to essentially ask a dog ‘How are you feeling?’ and get an answer. It could be used to monitor their welfare in any environment, to assess how effective enrichment activities might be in improving welfare, and pinpoint exactly what a dog finds emotionally distressing.”

Certain gut bacteria may induce metabolic changes following exposure to artificial sweeteners (Science Daily)

Summary: Artificial sweeteners have long been promoted as diet and health aids. But breaking research shows that these products may be leading to the very diseases they were said to help prevent: scientists have discovered that, after exposure to artificial sweeteners, our gut bacteria may be triggering harmful metabolic changes.

Artificial sweeteners — promoted as aids to weight loss and diabetes prevention — could actually hasten the development of glucose intolerance and metabolic disease, and they do so in a surprising way: by changing the composition and function of the gut microbiota — the substantial population of bacteria residing in our intestines. These findings, the results of experiments in mice and humans, were published September 17 in Nature. Dr. Eran Elinav of the Weizmann Institute of Science’s Department of Immunology, who led this research together with Prof. Eran Segal of the Department of Computer Science and Applied Mathematics, says that the widespread use of artificial sweeteners in drinks and food, among other things, may be contributing to the obesity and diabetes epidemic that is sweeping much of the world.

For years, researchers have been puzzling over the fact that non-caloric artificial sweeteners do not seem to assist in weight loss, with some studies suggesting that they may even have an opposite effect. Graduate student Jotham Suez in Dr. Elinav’s lab, who led the study, collaborated with lab member Gili Zilberman-Shapira and graduate students Tal Korem and David Zeevi in Prof. Segal’s lab to discover that artificial sweeteners, even though they do not contain sugar, nonetheless have a direct effect on the body’s ability to utilize glucose. Glucose intolerance — generally thought to occur when the body cannot cope with large amounts of sugar in the diet — is the first step on the path to metabolic syndrome and adult-onset diabetes.

The scientists gave mice water laced with the three most commonly used artificial sweeteners, in amounts equivalent to those permitted by the U.S. Food and Drug Administration (FDA). These mice developed glucose intolerance, as compared to mice that drank water, or even sugar water. Repeating the experiment with different types of mice and different doses of the artificial sweeteners produced the same results — these substances were somehow inducing glucose intolerance.

Next, the researchers investigated a hypothesis that the gut microbiota are involved in this phenomenon. They thought the bacteria might do this by reacting to new substances like artificial sweeteners, which the body itself may not recognize as “food.” Indeed, artificial sweeteners are not absorbed in the gastrointestinal tract, but in passing through they encounter trillions of the bacteria in the gut microbiota.

The researchers treated mice with antibiotics to eradicate many of their gut bacteria; this resulted in a full reversal of the artificial sweeteners’ effects on glucose metabolism. Next, they transferred the microbiota from mice that consumed artificial sweeteners to “germ-free,” or sterile, mice — resulting in a complete transmission of the glucose intolerance into the recipient mice. This, in itself, was conclusive proof that changes to the gut bacteria are directly responsible for the harmful effects to their host’s metabolism. The group even found that incubating the microbiota outside the body, together with artificial sweeteners, was sufficient to induce glucose intolerance in the sterile mice. A detailed characterization of the microbiota in these mice revealed profound changes to their bacterial populations, including new microbial functions that are known to infer a propensity to obesity, diabetes, and complications of these problems in both mice and humans.

Does the human microbiome function in the same way? Dr. Elinav and Prof. Segal had a means to test this as well. As a first step, they looked at data collected from their Personalized Nutrition Project (www.personalnutrition.org), the largest human trial to date to look at the connection between nutrition and microbiota. Here, they uncovered a significant association between self-reported consumption of artificial sweeteners, personal configurations of gut bacteria, and the propensity for glucose intolerance. They next conducted a controlled experiment, asking a group of volunteers who did not generally eat or drink artificially sweetened foods to consume them for a week, and then undergo tests of their glucose levels and gut microbiota compositions.

The findings showed that many — but not all — of the volunteers had begun to develop glucose intolerance after just one week of artificial sweetener consumption. The composition of their gut microbiota explained the difference: the researchers discovered two different populations of human gut bacteria — one that induced glucose intolerance when exposed to the sweeteners, and one that had no effect either way. Dr. Elinav believes that certain bacteria in the guts of those who developed glucose intolerance reacted to the chemical sweeteners by secreting substances that then provoked an inflammatory response similar to sugar overdose, promoting changes in the body’s ability to utilize sugar.

Prof. Segal states, “The results of our experiments highlight the importance of personalized medicine and nutrition to our overall health. We believe that an integrated analysis of individualized ‘big data’ from our genome, microbiome, and dietary habits could transform our ability to understand how foods and nutritional supplements affect a person’s health and risk of disease.”

According to Dr. Elinav, “Our relationship with our own individual mix of gut bacteria is a huge factor in determining how the food we eat affects us. Especially intriguing is the link between use of artificial sweeteners — through the bacteria in our guts — to a tendency to develop the very disorders they were designed to prevent; this calls for reassessment of today’s massive, unsupervised consumption of these substances.”
