Can Climate Science Predict Extreme Weather? (Scientific American)

Uncategorized, , , , , ,

This year’s rash of severe weather is changing climate science. As policymakers call for better information, scientists are scrambling to understand the link between increasing emissions and natural disaster

DENVER, Colo. – 2011 may well be remembered as the year of extremeweather in the United States, with drought in Texas, floods along the Mississippi River, a freak October snowstorm on the East Coast. Tornadoes alone would make the year memorable, with some 1,270 twisters causing 544 deaths and $25 billion in damages.

The outbreak is reshaping climate science, as researchers hone their abilities to predict severe weather and link the record-shattering destruction to humanity’s increasing emissions.

The goal: To provide better information to policymakers and local officials who must plan for and adapt to changes. “It’s a rapidly developing field,” said Peter Stott, head of climate monitoring and attribution at the Met Office, Britain’s national weather service.

Stott led one of the first studies attributing a single extreme weather event to climate change: The 2003 European heat wave, which killed 40,000 and was the hottest summer on record since 1540.  The study concluded that human influence more than doubled the event’s likelihood.

Last week, a study published in the journal Proceedings of the National Academy of Sciences concluded there was an 80 percent chance that the killer Russian heat wave of 2010 would not have happened without the added push of global warming.

Now, Stott and other researchers are melding weather forecasting skills with pioneering computer models to attribute – or link – individual weather events to climate change. Understanding how climate change influences the weather is increasingly seen as key to predicting natural disasters, Stott said, and the new studies should help policymakers anticipate the conditions and trends associated with weather extremes. “There’s this very strong connection between attribution and prediction,” noted Stott, who spoke on these issues before colleagues last week at the World Climate Research Programme conference here in Denver.

The efforts are steering the next steps of the Intergovernmental Panel on Climate Change, the international body of scientists that reviews and assesses the vast pool of climate research for policymakers worldwide. The next IPCC assessment is due in 2013 – the fifth from the panel since 1990. For the first time it will include “predictions” – near-term and long-term climate forecasts based on actual conditions – instead of “projections” that simulate hypothetical scenarios and carbon emission rates.

The distinction is an advance for climate science and the IPCC, said Kevin Trenberth, who runs the Climate Analysis Section at the National Center for Atmospheric Research in Boulder, Colo.

Previous IPCC assessments have cited projections that are not grounded in current or historical conditions. Instead, policymakers are given “what-if” scenarios, such as how the future climate might react to different greenhouse-gas emissions over the coming decades. The results show changes between two assumed moments in time, Trenberth said, but they lack a starting point tied to observed data and, ultimately, are informed guesses of future carbon dioxide levels and their consequences.

Climate model predictions, on the other hand, are like weather forecasts. They start from a current or historical moment to analyze climate changes. By grabbing more measurements and using new techniques, advanced climate models reveal more clearly how the atmosphere responds to increased water moisture, warmer sea temperatures and melting sea ice, all impacts of increased carbon. Compared to projections, predictions allow scientists to offer near-term climate forecasts, which should help policymakers prepare for potential adaptations in the next few decades.

The change from projections to predictions is made possible in part by a new generation of more powerful computer models. The last IPCC assessment report, published in 2007, made minor mention of feedbacks – environmental processes and interactions that can intensify extreme climate events, said Sonia Seneviratne, a professor at the Swiss Federal Institute of Technology in Zurich, who specializes on the topic. New data have since opened up scientists’ understanding of their importance.

Seneviratne is the lead author of an IPCC special report to be released later this month that focuses on climate change and extreme events. Research in this area has been “substantial and justifies a separate assessment,” she said, adding that it’s particularly a topic of interest for officials concerned with disaster preparedness and risk reduction.

The special report concludes that scientists are “virtually certain” the world will see more extremes in heat and that some places in the world will become “increasingly marginal as places to live,” according to the Associated Press, which obtained a draft. The draft also concludes there is at least a two-in-three chance that man-made global warming has already worsened weather extremes, according to the AP. The document is subject to change and needs approval from diplomats meeting in Uganda mid-month.

There are some caveats to these new climate predictions, however.

Writing in a scientific journal last year, Trenberth warned colleagues that the promise of more accurate representations of climate change will introduce new scientific uncertainties inherent to modeling more complex and realistic situations. Just as weather forecasting evokes its share of skepticism and doubt, climate predictions will likely represent a new communications challenge – and fodder for controversy and criticism – for climate scientists, said Trenberth.

“It’s about communication,” agreed Stott, who is the lead author of the 2013 IPCC report’s section on attribution and detection of climate change. “An understanding of where extreme weather fits into the longer-term picture of a changing climate helps people put this into context, and [whether] this is something that is going to become more common in the future and therefore we need to give more attention and be more prepared for these things.”

Stott and other scientists at a handful of modeling centers worldwide are focusing on the relation between climate change and extreme weather through a new initiative, Attribution of Climate-related Events. Stott says the project will move scientists further along toward forecasting extreme events and mapping the interactions with climate change.

“The goal is to be able to develop the tools and the skills, so we know when we can be confident and provide trustworthy assessments, and to do this in a timely fashion – in the immediate aftermath of a particular situation,” Stott said. “At the moment, we’re not really geared up for that. It’s very much research mode.> We’ve hardly scratched the surface.”

Dr. Kevin Trenberth advocates reversing the ‘null hypothesis’

The debate may largely be drawn along political lines, but the human role in climate change remains one of the most controversial questions in 21st century science. Writing in WIREs Climate Change Dr Kevin Trenberth, from the National Center for Atmospheric Research, argues that the evidence for anthropogenic climate change is now so clear that the burden of proof should lie with research which seeks to disprove the human role.

In response to Trenberth’s argument a second review, by Dr Judith Curry, focuses on the concept of a ‘null hypothesis’ the default position which is taken when research is carried out. Currently the null hypothesis for climate change attribution research is that humans have no influence.

“Humans are changing our climate. There is no doubt whatsoever,” said Trenberth. “Questions remain as to the extent of our collective contribution, but it is clear that the effects are not small and have emerged from the noise of natural variability. So why does the science community continue to do attribution studies and assume that humans have no influence as a null hypothesis?”

To show precedent for his position Trenberth cites the 2007 report by the Intergovernmental Panel on Climate Change which states that global warming is “unequivocal”, and is “very likely” due to human activities.

Trenberth also focused on climate attribution studies which claim the lack of a human component, and suggested that the assumptions distort results in the direction of finding no human influence, resulting in misleading statements about the causes of climate change that can serve to grossly underestimate the role of humans in climate events.

“Scientists must challenge misconceptions in the difference between weather and climate while attribution studies must include a human component,” concluded Trenberth. “The question should no longer be is there a human component, but what is it?”

In a second paper Dr Judith Curry, from the Georgia Institute of Technology, questions this position, but argues that the discussion on the null hypothesis serves to highlight fuzziness surrounding the many hypotheses related to dangerous climate change.

“Regarding attribution studies, rather than trying to reject either hypothesis regardless of which is the null, there should be a debate over the significance of anthropogenic warming relative to forced and unforced natural climate variability,” said Curry.

Curry also suggested that the desire to reverse the null hypothesis may have the goal of seeking to marginalise the climate sceptic movement, a vocal group who have challenged the scientific orthodoxy on climate change.

“The proponents of reversing the null hypothesis should be careful of what they wish for,” concluded Curry. “One consequence may be that the scientific focus, and therefore funding, would also reverse to attempting to disprove dangerous anthropogenic climate change, which has been a position of many sceptics.”

“I doubt Trenberth’s suggestion will find much support in the scientific community,” said Professor Myles Allen from Oxford University, “but Curry’s counter proposal to abandon hypothesis tests is worse. We still have plenty of interesting hypotheses to test: did human influence on climate increase the risk of this event at all? Did it increase it by more than a factor of two?”

Mixed messages on climate ‘vulnerability’ (BBC)

Uncategorized, , , , , , , , , , , ,

13 November 2011 Last updated at 14:45 GMT

By Richard Black

Cyclist in floodThere are concerns that climate change may exacerbate flooding in cities such as Bangkok

One of the most striking new voices on climate change that’s emerged since the UN summit in Copenhagen two years ago is the Climate Vulnerable Forum.

The grouping includes small island states vulnerable to extreme weather events and sea level rise, those with immense spans of low-lying coastline such as Vietnam and Bangladesh, and dry nations of East Africa.

It’s currently holding a meeting in Bangladesh, with UN Secretary-General Ban Ki-moon as the keynote speaker.

These countries feel vulnerable as a result of several types of projected climate impact.

In increasing order of suddenness, there are what you might call “steady-state” impacts such as rising sea levels; increased separation of weather into more concentrated wet periods and dry periods; and a greater occurrence of extreme weather events such as hurricanes, floods, heatwaves and droughts.

But what can science really tell us about these extremes?

While the vulnerable meet in Dhaka, the Intergovernmental Panel on Climate Change (IPCC) will be sitting down in Kampala to answer the question.

For almost a week, government delegates will pore over the summary of the IPCC’s latest report on extreme weather, with the lead scientific authors there as well. They’re scheduled to emerge on Friday with an agreed document.

The draft, which has found its way into my possession, contains a lot more unknowns than knowns.

On the one hand, it says it is “very likely” that the incidence of cold days and nights has gone down and the incidence of warm days and nights has risen globally.

And the human and financial toll of extreme weather events has risen.

Human hand fingered?

But when you get down to specifics, the academic consensus is far less certain.

Glacier, AlaskaEnhanced glacier melt could speed up sea level rise in the coming decades

There is “low confidence” that tropical cyclones have become more frequent, “limited-to-medium evidence available” to assess whether climatic factors have changed the frequency of floods, and “low confidence” on a global scale even on whether the frequency has risen or fallen.

In terms of attribution of trends to rising greenhouse gas concentrations, the uncertainties continue.

While it is “likely” that anthropogenic influences are behind the changes in cold days and warm days, there is only “medium confidence” that they are behind changes in extreme rainfall events, and “low confidence” in attributing any changes in tropical cyclone activity to greenhouse gas emissions or anything else humanity has done.

(These terms have specific meanings in IPCC-speak, with “very likely” meaning 90-100% and “likely” 66-100%, for example.)

And for the future, the draft gives even less succour to those seeking here a new mandate for urgent action on greenhouse gas emissions, declaring: “Uncertainty in the sign of projected changes in climate extremes over the coming two to three decades is relatively large because climate change signals are expected to be relatively small compared to natural climate variability”.

It’s also explicit in laying out that the rise in impacts we’ve seen from extreme weather events cannot be laid at the door of greenhouse gas emissions: “Increasing exposure of people and economic assets is the major cause of the long-term changes in economic disaster losses (high confidence).

“Long-term trends in normalized economic disaster losses cannot be reliably attributed to natural or anthropogenic climate change.”

The succour only lasts for so long, however.

If the century progresses without restraints on greenhouse gas emissions, their impacts will come to dominate, it forecasts:

  • “It is very likely that the length, frequency and/or intensity of warm spells, including heat waves, will continue to increase over most land areas…
  • “It is likely that the frequency of heavy precipitation or the proportion of total rainfall from heavy falls will increase in the 21st Century over many areas of the globe…
  • “Mean tropical cyclone maximum wind speed is likely to increase…
  • “There is medium confidence that droughts will intensify in the 21st Century in some seasons and areas…
  • “Low-probability high-impact changes associated with the crossing of poorly understood thresholds cannot be excluded, given the transient and complex nature of the climate system.”

The draft report makes clear that lack of evidence or lack of confidence on a particular impact doesn’t mean it won’t occur; just that it’s hard to tell.

Climate a distraction?

It’s impossible to read the draft without coming away with the impression that with or without anthropogenic climate change, extreme weather impacts are going to be felt more and more, simply because there are more and more people on planet Earth – particularly in the swelling “megacities” of the developing world that overwhelmingly lie on the coast or on big rivers close to the coast.

President NasheedPresident Nasheed of the Maldives has warned that climate change may mean the end of his nation

The current Bangkok floods are a case in point.

As UK academic Mike Hulme and others have argued, such events will occur whether exacerbated by climate change or not; and vulnerable societies need protection irrespective of climate change.

He’s argued for a divorce, therefore, between the issues of adaptation, which he says could usefully be added into the overall process of overseas development assistance, and mitigation of emissions.

It’s not proved to be a popular notion with developing world governments, which remain determined to tie the two together in the UN climate process.

Governments of vulnerable countries argue that as developed nations caused the climate change problem, they must compensate those that suffer its impacts with money above and beyond aid.

Developing countries like the fact that under the UN climate process, the rich are committed to funding adaptation for the poor.

Yet as the brief prepared for the Dhaka meeting by the humanitarian charity Dara shows, it isn’t happening anywhere near as fast as it ought to be.

Only 8% of the “fast-start finance” pledged in Copenhagen, it says, has actually found its way to recipients.

It’s possible – no, it’s “very likely” – that the IPCC draft will be amended as the week progresses, and presumably the governments represented at the Climate Vulnerable Forum will be asking their delegates to inject a greater sense of urgency.

Although there are sobering messages, they’re not for everyone.

The warning that “some local areas will become increasingly marginal as places to live or in which to maintain livelihoods” under increased climate impacts, and that “for locations such as atolls, in some cases it is possible that many residents will have to relocate” are, in their understated way, quite chilling.

But very few of the world’s seven billion live on atolls; so will this be enough to provide a wake-up call to other countries?

It’s also possible to argue that extreme weather isn’t really the issue for the small island developing states, or for those with long flat coastlines.

The big issue (which the IPCC is much more confident about) is sea level rise – slow, progressive, predictable; capable of being dealt with in some cases (think the Netherlands) provided the will and money are there.

But capable of wiping a country off the map if those two factors are absent.

This is one of the reasons why the Climate Vulnerable Forum established itself.

They felt that although both developed and developing nations understood vulnerability in theory, they didn’t get the message viscerally.

Whether they will by the end of the week when the IPCC releases the final version, I’m not so sure.

Anthropologists Consider a New Code of Ethics (The Chronicle of Higher Education)

Uncategorized, , , ,

November 20, 2011

By Dan Berrett

Today’s anthropologists are apt to work far away from the unspoiled villages that brought fame to the discipline’s early practitioners.

Instead, they might be in a hospital room observing patients, at a construction site gauging its archaeological significance, or in a corporate office examining organizational behavior, among other scenarios.

Those diverse contexts may explain why it has proved to be no easy job for anthropologists to create a new set of ethical guidelines. After three years spent seeking opinion and working on new guidelines, the American Anthropological Association is moving toward changes that some in the discipline fear will water down anthropologists’ obligations to the people they study.

“Dealing with ethics codes is complicated,” said David H. Price, a member of the committee charged with revising the guidelines. The word was echoed last week by fellow committee members at a panel on ethics at the association’s annual meeting here. Basic ethical principles might seem clear at the outset, but then point to different courses of action depending on the context, said Mr. Price, a professor at Saint Martin’s University, in Washington. “You can start with something simple, like ‘Do no harm,'” he said, and then find yourself hamstrung if those guidelines are written too specifically ­— or lost at sea if they are too vague.

One of the most notable changes in the proposed new code was to remove what many anthropologists call the “prime directive.”

The previous code, which dates to 1998 (though incremental changes have been made since then), told anthropologists that they “have primary ethical obligations to the people, species, and materials they study and to the people with whom they work.”

By many accounts, that directive has meant that an anthropologist’s obligation to his or her research subject can eclipse the goal of acquiring new knowledge. In other words, if research goes against the interests of subjects, then that research ought to be stopped.

The newer version, which the association’s executive board accepted for review at this year’s meeting but did not formally adopt, is more nuanced. It explains that the primary ethical obligation is “to avoid doing harm to the lives, communities, or environments” that anthropologists study.

The shift struck some as important. At other sessions during the annual meeting, several speakers and audience members said they held themselves to a different standard. It was not enough to keep from hurting their subjects. They should advocate for them.

The new code may do little to change that sense of obligation. It persists, in part, because of the assumption that an anthropologist is still that lone researcher closely observing a vulnerable tribe in a remote area, some on the committee said.

“That pure anthropology maybe never existed,” said Dena K. Plemmons, chair of the committee and a research ethicist at the University of California at San Diego. “Our subjects are tremendously diverse and we have diverse responsibilities.”

For example, Simon J. Craddock Lee, an assistant professor of medical anthropology at the University of Texas Southwestern Medical Center at Dallas, said his subjects are “well-paid cancer surgeons who give care to disenfranchised people.”

He has obligations to both groups, he said. “If my subjects are doctors, how do I balance my obligations to the people who are truly vulnerable?”

One audience member suggested that his chief loyalty should be to the person or group who is most at risk of harm among those being studied.

While that might seem straightforward, Mr. Lee replied, everyone—including the poor and vulnerable—has an agenda.

“We can’t assume there’s a David-and-Goliath relationship,” he said. “It’s not clean enough to say you can sort the good sheep from the goats.”

Ethics, or Politics?

The question of clandestine research offered another case in which a seemingly simple principle can become complicated when applied to field work. To some, discouraging clandestine research meant that an anthropologist should never deceive subjects and should always share his or her work publicly.

But Laura A. McNamara, an anthropologist who works for the U.S. Department of Energy’s Sandia National Laboratories, disagreed, saying that some anthropologists study classified information; they cannot make their findings public.

Even deceit can have its place, she added. Nancy Scheper-Hughes, a professor of medical anthropology at the University of California at Berkeley, for example, did research that exposed the organ-trafficking trade. Her work never would have been made public if she had believed that her primary obligation was to her subjects, who were, after all, organ traffickers.

The real problem, Ms. McNamara and her fellow committee members agreed, is not when research is clandestine, but when it is “compartmentalized,” which means a researcher may not know who is using or financing the research, or what the implications will be.

“There is no way you can communicate an informed perspective,” she said.

How anthropologists wield ethical guidelines also came up for scrutiny. Anthropologists push most fervently to revise their ethics when they disagree with the politics underlying controversial research, several speakers noted.

“We go to high Sturm und Drang” about ethics, Ms. McNamara said, when political objections arise about who is doing anthropological research for whom—especially when it’s for the government, corporations, or the rich and powerful. “Ethics becomes conflated with politics in ways that I find profoundly distressing,” she said.

Some anthropologists pushed to revise the ethics code in 2007, said Ms. Plemmons, when acontroversy erupted over the Human Terrain System, a program that embedded anthropologists with United States military units. The association’s executive board disapproved of anthropologists’ involvement in the act of making war, calling it “an unacceptable application of anthropological expertise” which should, instead, serve “the humane causes of global peace and social justice.”

Education and Punishment

Committee members said they also heard from anthropologists who wanted an ethics code that could be enforced. That way, anthropologists who act badly could be punished or cast out of the discipline.

The association once held the power to adjudicate claims of ethical breaches, Mr. Price said. But when he reviewed records of the association’s work from that period, he saw that most claims involved what he called “sleaziness,” or cases in which professors harassed students or took credit for their research. While unethical, those breaches were not specific to anthropology and needed no separate code beyond those that already exist, he said.

Assuming responsibility for adjudicating ethical disputes presented another set of problems, said several speakers. It would mean a new mission and structure for the association, which would have to hire investigators to police wrongdoing and claim the power to credential who gets to call him- or herself an anthropologist. Many times, such complaints can be handled through an institutional review board or a university.

The association has seen first-hand how difficult such investigations can be. In 2001 and 2002, it probed claims of wrongdoing and ethical malpractice against anthropologists and geneticists in the Amazon in the 1960s. The association later published a report finding fault with some of the scholars’ conduct in what became known as the Darkness in El Dorado controversy (after a journalist’s account by that name), only to rescind its own report in 2005.

Besides, the ethics committee surveyed members and learned that most anthropologists are not all that interested in using ethical guidelines as a means to punish each other. What most anthropologists wanted, they said, was some form of general guidance, an educational tool to train future anthropologists.

Are We Getting Nicer? (N.Y. Times)

Uncategorized, , , , , , , ,

By NICHOLAS D. KRISTOF
Published: November 23, 2011

It’s pretty easy to conclude that the world is spinning down the toilet.

So let me be contrary and offer a reason to be grateful this Thanksgiving. Despite the gloomy mood, the historical backdrop is stunning progress in human decency over recent centuries.

War is declining, and humanity is becoming less violent, less racist and less sexist — and this moral progress has accelerated in recent decades. To put it bluntly, we humans seem to be getting nicer.

That’s the central theme of an astonishingly good book just published by Steven Pinker, a psychology professor at Harvard. It’s called “The Better Angels of Our Nature,” and it’s my bet to win the next Pulitzer Prize for nonfiction.

“Today we may be living in the most peaceable era in our species’ existence,” Pinker writes, and he describes this decline in violence as possibly “the most important thing that has ever happened in human history.”

He acknowledges: “In a century that began with 9/11, Iraq, and Darfur, the claim that we are living in an unusually peaceful time may strike you as somewhere between hallucinatory and obscene.”

Still, even in a 20th century notorious for world war and genocide, only around 3 percent of humans died from such man-made catastrophes. In contrast, a study of Native-American skeletons from hunter-gather societies found that some 13 percent had died of trauma. And in the 17th century, the Thirty Years’ War reduced Germany’s population by as much as one-third.

Wars make headlines, but there are fewer conflicts today, and they typically don’t kill as many people. Many scholars have made that point, most notably Joshua S. Goldstein in his recent book “Winning the War on War: The Decline of Armed Conflict Worldwide.” Goldstein also argues that it’s a myth that civilians are more likely to die in modern wars.

Look also at homicide rates, which are now far lower than in previous centuries. The murder rate in Britain seems to have fallen by more than 90 percent since the 14th century.

Then there are the myriad forms of violence that were once the banal backdrop of daily life. One game in feudal Europe involved men competing to head-butt to death a cat that had been nailed alive to a post. One reason this was considered so entertaining: the possibility that it would claw out a competitor’s eye.

Think of fairy tales and nursery rhymes. One academic study found that modern children’s television programs have 4.8 violent scenes per hour, compared with nursery rhymes with 52.2.

The decline in brutality is true of other cultures as well. When I learned Chinese, I was startled to encounter ideographs like the one of a knife next to a nose: pronounced “yi,” it means “cutting off a nose as punishment.” That’s one Chinese character that students no longer study.

Pinker’s book rang true to me partly because I often report on genocide and human rights abuses. I was aghast that Darfur didn’t prompt more of an international response from Western governments, but I was awed by the way American university students protested on behalf of a people who lived half a world away.

That reflects a larger truth: There is global consensus today that slaughtering civilians is an outrage. Governments may still engage in mass atrocities, but now they hire lobbyists and public relations firms to sanitize the mess.

In contrast, until modern times, genocide was simply a way of waging war. The Bible repeatedly describes God as masterminding genocide (“thou shalt save alive nothing that breatheth” — Deuteronomy 20:16), and European-Americans saw nothing offensive about exterminating Native Americans. One of my heroes, Theodore Roosevelt, later a winner of the Nobel Peace Prize, was unapologetic: “I don’t go so far as to think that the only good Indians are the dead Indians, but I believe nine out of ten are, and I shouldn’t like to inquire too closely in the case of the tenth.”

The pace of moral progress has accelerated in the last few decades. Pinker notes that on issues such as civil rights, the role of women, equality for gays, beating of children and treatment of animals, “the attitudes of conservatives have followed the trajectory of liberals, with the result that today’s conservatives are more liberal than yesterday’s liberals.”

The reasons for these advances are complex but may have to do with the rise of education, the decline of chauvinism and a growing willingness to put ourselves in the shoes (increasingly, even hooves) of others.

Granted, the world still faces brutality and cruelty. That’s what I write about the rest of the year! But let’s pause for a moment to acknowledge remarkable progress and give thanks for the human capacity for compassion and moral growth.

Drillers using counterinsurgency experts (Pittsburgh Post-Gazette)

Marcellus industry taking a page from the military to deal with media, resident opposition
Sunday, November 13, 2011
By Don Hopey, Pittsburgh Post-Gazette

Marcellus Shale gas drilling spokesmen at an industry conference in Houston said their companies are employing former military counterinsurgency officers and recommended using military-style psychological operations strategies, or psyops, to deal with media inquiries and citizen opposition to drilling in Pennsylvania communities.

Matt Pitzarella, a Range Resources spokesman speaking to other oil and gas industry spokespeople at the conference last week, said the company hires former military psyops specialists who use those skills in Pennsylvania.

Mr. Pitzarella’s statements and related comments made by a spokesman for Anadarko Petroleum were recorded by a member of an environmental group who provided them to the Pittsburgh Post-Gazette.

“We have several former psyops folks that work for us at Range because they’re very comfortable in dealing with localized issues and local governments,” Mr. Pitzarella said during the last half of a 23-minute presentation in a conference session. The session was titled “Designing a Media Relations Strategy to Overcome Concerns Surrounding Hydraulic Fracturing.”

“Really all they do is spend most of their time helping folks develop local ordinances and things like that,” he continued. “But very much having that understanding of psyops in the Army and the Middle East has applied very helpfully here for us in Pennsylvania.”

Matt Carmichael, manager of external affairs for Anadarko Petroleum, which has nearly 300,000 acres of Marcellus Shale gas holdings under lease in Central Pennsylvania, gave a speech urging industry media spokesmen to read a military counterinsurgency manual for tips in dealing with opponents to shale gas development.

“Download the U.S. Army/Marine Corps Counterinsurgency Manual, because we are dealing with an insurgency,” Mr. Carmichael said in a session titled “Understanding How Unconventional Oil & Gas Operators are Developing a Comprehensive Media Relations Strategy to Engage Stakeholders and Educate the Public.”

“There’s a lot of good lessons in there,” he said, “and coming from a military background, I found the insight extremely remarkable.”

The remarks of both Mr. Pitzarella and Mr. Carmichael were recorded at the conference by Sharon Wilson, an activist and member of the Earthworks Oil and Gas Accountability Project, a national environmental nonprofit focused on the impacts of mineral and energy development.

She said the term “insurgent” shows what the industry thinks about the communities where it is drilling.

“What’s clear to me is that they are having to use some very extreme measures in our neighborhoods. And it seems like they view it as an occupation,” Ms. Wilson said.

Psychological operations is a term used in the military and intelligence agencies and involves use of selective communications and sometimes misinformation and deception to manipulate public perception. According to a U.S. Army careers website, psyops specialists “assess the information needs of a target population and develop and deliver the right message at the right time and place to create the intended result.”

Environmental groups and residents of communities where Marcellus drilling has been controversial and sometimes contentious were quick to seize on the comments. They said they reflected the industry’s battlefield mentality and disinformation strategy when dealing with communities and individuals.

“This is the level of disdain, deception and belligerence that we are dealing with,” said Arthur Clark, an Oil & Gas Committee co-chair and member of the executive committee of the Pennsylvania chapter of the Sierra Club.

“On tape and in print, for once, an industry literally at war with local residents, even labeling them ‘insurgents.’ I don’t recall seeing anyone toting an AK-47 at any of the public meetings or rallies regarding frack gas development.”

“It sounds like the gas companies are utilizing military ‘psyops’ in gas patch communities,” said Bill Walker, a spokesman for Earthworks.

Mr. Carmichael did not return calls requesting comment, but John Christiansen, director of external communications for Anadarko, issued a statement, addressing Mr. Carmichael’s use of the term insurgency.

“The reference was not reflective of our core values. Our community efforts are based upon open communication, active engagement and transparency, which are all essential in building fact-based knowledge and earning public trust.”

Mr. Pitzarella explained his remarks by saying the industry employs large numbers of veterans, including an attorney with a psyops background who “spent time in the Middle East,” with temperaments “well suited” to handling the sometimes “emotional situations” at community meetings the company holds to explain its well drilling and fracking operations.

“To suggest that the two comments made at unrelated [conference sessions] are a strategy is dishonest,” Mr. Pitzarella said. “[Range has] been transparent and accountable, and that’s not something we would do if we were trying to mislead people.”

But despite repeated questions, Mr. Pitzarella would not name the Range attorney with a psyops background. The company does employ James Cannon, whose LinkIn page lists him as a “public affairs specialist” for Range and a member of the U.S. Army’s “303 Psyop Co.,” a reserve unit in Pittsburgh.

Mr. Cannon could not be reached for comment.

Dencil Backus of Mount Pleasant, a California University of Pennsylvania communications professor who teaches public relations, once had Mr. Pitzarella in his class. Mr. Backus said it’s “obvious we have all been targeted” with a communications strategy that employs misinformation and intimidation, and includes homespun radio and television ads touting “My drilling company? Range Resources”; community “informational” meetings that emphasize the positive and ignore potential problems caused by drilling and fracking; and recent lawsuits, threats of lawsuits and commercial boycotts.

“There’s just been a number of ways in which they’ve sought to intimidate us,” said Mr. Backus, who has been a coordinator of a citizens committee that advised Mount Pleasant on a proposed Marcellus ordinance. “It’s one of the most unethical things I have ever seen.”

The filmmaker: A push to broaden the reach of ‘ski porn’ (The Daily Climate)

Mossop-sherpas

Nov. 7, 2011

David Mossop and Sherpas Cinemas are transforming ski flicks, turning the usual plot-less, context-less jumble of skiing images into a message about environmental destruction, mass consumption and climate change.

Interview conducted and condensed by Rae Tyson

The Daily Climate

A critically acclaimed film combining action, free-style skiing and a climate impact message debuted this fall. Representing the leading edge of a new wave of ski films, All.I.Can juxtaposes “ski-porn” – plot-less montages of expert skiers flying down and off impossibly steep mountainsides – against images of environmental destruction and mass consumption. Reviewers say the movie, available on DVD and to be released on iTunes on Nov. 14, could change the genre permanently.

With enough creativity, ski films have the capacity to address almost any topic. – David Mossop

British Columbia cinematographers Eric Crossland and Dave Mossop filmed the movie in Chile, Canada, Morocco, Greenland and Alaska. ESPN’s Jamey Voss calls it “the best movie in skiing.” Dave Mossop has been doing ski films and photography for years. This is his first attempt at a film with a strong social message.

Your film company, Sherpas Cinema, has said “the time has come for a ski film that stands for something.” Explain the inspiration for All.I.Can.

The classic ski-porn formula works brilliantly and will always have its place. But skiing is about so much more than just porn. The mountains bring us every emotion in the book. With enough creativity, ski films have the capacity to address almost any topic.

All.I.Can. Official Teaser from Sherpas Cinema on Vimeo.

Has this film altered your view about your ability to affect change? 

This project has really opened my eyes to what is possible, and now it almost feels like our duty to see how far that envelope can be pushed.

What convinced you to focus on climate change?

The root of All.I.Can is the relationship between mountain people and nature. Skiers are more reliant on weather and climate than almost any other subculture. A well-crafted film has the potential to act as a trigger: If mountain culture doesn’t stand up, who will?

You traveled around the world to shoot this film. Did you see evidence of the impact of climate change in any of the locations you visited?

A big part of the climate problem is that it is too slow for us humans to perceive. But, at almost every location we went, we would hear stories from the elders indicating a warming trend.

Such as?

The Inuit of Greenland talked about the more challenging hunting conditions due to ice breakup. Bud Stoll and Mary Woodward, two of the older skiers in our film, reminisced about the deep winters the Kootenays when they were youngsters. The Chilean gauchos and Moroccan porters recalled stories of colder snowier winters.

Unchecked, do you believe that climate change might impact skiing – and other winter sports?

I know as little about climate change as everyone else. But it isn’t hard to sense that the human race is running an unsustainable program.

The reviews so far have been impressive. ESPN, for example, called All.I.Can “a wake-up call in many ways.”

We are totally overwhelmed by the response. The world was ready for this kind of cinematic discussion and the idea is striking a chord with skiers and non-skiers alike.

Mossop-volcanoSome question the carbon neutrality of this project. You flew all over the globe and used fuel-guzzling helicopters. How would you respond to that?

We feel that the extra resources used in the film production are far overshadowed by the potential energy of All.I.Can. A truly beautiful film can inspire the whole world and influence countless human decisions in the future.

How did you offset the impact?

We worked with Native Energy to offset the project using carbon credits. They use the money to either counter our carbon emissions directly or invest in future innovations that build toward a sustainable future.

Any plans for future projects with an environmental theme?

I expect an environmental theme will become an undertone in all our future projects, but currently we have no locked plans.

World headed for irreversible climate change in five years, IEA warns (The Guardian)

If fossil fuel infrastructure is not rapidly changed, the world will ‘lose for ever’ the chance to avoid dangerous climate change

The world is likely to build so many fossil-fuelled power stations, energy-guzzling factories and inefficient buildings in the next five years that it will become impossible to hold global warming to safe levels, and the last chance of combating dangerous climate change will be “lost for ever”, according to the most thorough analysis yet of world energy infrastructure.

Anything built from now on that produces carbon will do so for decades, and this “lock-in” effect will be the single factor most likely to produce irreversible climate change, the world’s foremost authority on energy economics has found. If this is not rapidly changed within the next five years, the results are likely to be disastrous.

“The door is closing,” Fatih Birol, chief economist at the International Energy Agency, said. “I am very worried – if we don’t change direction now on how we use energy, we will end up beyond what scientists tell us is the minimum [for safety]. The door will be closed forever.”

If the world is to stay below 2C of warming, which scientists regard as the limit of safety, then emissions must be held to no more than 450 parts per million (ppm) of carbon dioxide in the atmosphere; the level is currently around 390ppm. But the world’s existing infrastructure is already producing 80% of that “carbon budget”, according to the IEA’s analysis, published on Wednesday. This gives an ever-narrowing gap in which to reform the global economy on to a low-carbon footing.

If current trends continue, and we go on building high-carbon energy generation, then by 2015 at least 90% of the available “carbon budget” will be swallowed up by our energy and industrial infrastructure. By 2017, there will be no room for manoeuvre at all – the whole of the carbon budget will be spoken for, according to the IEA’s calculations.

Birol’s warning comes at a crucial moment in international negotiations on climate change, as governments gear up for the next fortnight of talks in Durban, South Africa, from late November. “If we do not have an international agreement, whose effect is put in place by 2017, then the door to [holding temperatures to 2C of warming] will be closed forever,” said Birol.

But world governments are preparing to postpone a speedy conclusion to the negotiations again. Originally, the aim was to agree a successor to the 1997 Kyoto protocol, the only binding international agreement on emissions, after its current provisions expire in 2012. But after years of setbacks, an increasing number of countries – including the UK, Japan and Russia – now favour postponing the talks for several years.

Both Russia and Japan have spoken in recent weeks of aiming for an agreement in 2018 or 2020, and the UK has supported this move. Greg Barker, the UK’s climate change minister, told a meeting: “We need China, the US especially, the rest of the Basic countries [Brazil, South Africa, India and China] to agree. If we can get this by 2015 we could have an agreement ready to click in by 2020.” Birol said this would clearly be too late. “I think it’s very important to have a sense of urgency – our analysis shows [what happens] if you do not change investment patterns, which can only happen as a result of an international agreement.”

Nor is this a problem of the developing world, as some commentators have sought to frame it. In the UK, Europe and the US, there are multiple plans for new fossil-fuelled power stations that would contribute significantly to global emissions over the coming decades.

The Guardian revealed in May an IEA analysis that found emissions had risen by a record amount in 2010, despite the worst recession for 80 years. Last year, a record 30.6 gigatonnes (Gt) of carbon dioxide poured into the atmosphere from burning fossil fuels, a rise of 1.6Gt on the previous year. At the time, Birol told the Guardian that constraining global warming to moderate levels would be “only a nice utopia” unless drastic action was taken.

The new research adds to that finding, by showing in detail how current choices on building new energy and industrial infrastructure are likely to commit the world to much higher emissions for the next few decades, blowing apart hopes of containing the problem to manageable levels. The IEA’s data is regarded as the gold standard in emissions and energy, and is widely regarded as one of the most conservative in outlook – making the warning all the more stark. The central problem is that most industrial infrastructure currently in existence – the fossil-fuelled power stations, the emissions-spewing factories, the inefficient transport and buildings – is already contributing to the high level of emissions, and will do so for decades. Carbon dioxide, once released,stays in the atmosphere and continues to have a warming effect for about a century, and industrial infrastructure is built to have a useful life of several decades.

Yet, despite intensifying warnings from scientists over the past two decades, the new infrastructure even now being built is constructed along the same lines as the old, which means that there is a “lock-in” effect – high-carbon infrastructure built today or in the next five years will contribute as much to the stock of emissions in the atmosphere as previous generations.

The “lock-in” effect is the single most important factor increasing the danger of runaway climate change, according to the IEA in its annual World Energy Outlook, published on Wednesday.

Climate scientists estimate that global warming of 2C above pre-industrial levels marks the limit of safety, beyond which climate change becomes catastrophic and irreversible. Though such estimates are necessarily imprecise, warming of as little as 1.5C could cause dangerous rises in sea levels and a higher risk of extreme weather – the limit of 2C is now inscribed in international accords, including the partial agreement signed at Copenhagen in 2009, by which the biggest developed and developing countries for the first time agreed to curb their greenhouse gas output.

Another factor likely to increase emissions is the decision by some governments to abandon nuclear energy, following the Fukushima disaster. “The shift away from nuclear worsens the situation,” said Birol. If countries turn away from nuclear energy, the result could be an increase in emissions equivalent to the current emissions of Germany and France combined. Much more investment in renewable energy will be required to make up the gap, but how that would come about is unclear at present.

Birol also warned that China – the world’s biggest emitter – would have to take on a much greater role in combating climate change. For years, Chinese officials have argued that the country’s emissions per capita were much lower than those of developed countries, it was not required to take such stringent action on emissions. But the IEA’s analysis found that within about four years, China’s per capita emissions were likely to exceed those of the EU.

In addition, by 2035 at the latest, China’s cumulative emissions since 1900 are likely to exceed those of the EU, which will further weaken Beijing’s argument that developed countries should take on more of the burden of emissions reduction as they carry more of the responsibility for past emissions.

In a recent interview with the Guardian recently, China’s top climate change official, Xie Zhenhua, called on developing countries to take a greater part in the talks, while insisting that developed countries must sign up to a continuation of the Kyoto protocol – something only the European Union is willing to do. His words were greeted cautiously by other participants in the talks.

Continuing its gloomy outlook, the IEA report said: “There are few signs that the urgently needed change in direction in global energy trends is under way. Although the recovery in the world economy since 2009 has been uneven, and future economic prospects remain uncertain, global primary energy demand rebounded by a remarkable 5% in 2010, pushing CO2 emissions to a new high. Subsidies that encourage wasteful consumption of fossil fuels jumped to over $400bn (£250.7bn).”

Meanwhile, an “unacceptably high” number of people – about 1.3bn – still lack access to electricity. If people are to be lifted out of poverty, this must be solved – but providing people with renewable forms of energy generation is still expensive.

Charlie Kronick of Greenpeace said: “The decisions being made by politicians today risk passing a monumental carbon debt to the next generation, one for which they will pay a very heavy price. What’s seriously lacking is a global plan and the political leverage to enact it. Governments have a chance to begin to turn this around when they meet in Durban later this month for the next round of global climate talks.”

One close observer of the climate talks said the $400bn subsidies devoted to fossil fuels, uncovered by the IEA, were “staggering”, and the way in which these subsidies distort the market presented a massive problem in encouraging the move to renewables. He added that Birol’s comments, though urgent and timely, were unlikely to galvanise China and the US – the world’s two biggest emittters – into action on the international stage.

“The US can’t move (owing to Republican opposition) and there’s no upside for China domestically in doing so. At least China is moving up the learning curve with its deployment of renewables, but it’s doing so in parallel to the hugely damaging coal-fired assets that it is unlikely to ever want (to turn off in order to) to meet climate targets in years to come.”

Energy demand

Energy demand Source: IEAChristiana Figueres, the UN climate chief, said the findings underlined the urgency of the climate problem, but stressed the progress made in recent years. “This is not the scenario we wanted,” she said. “But making an agreement is not easy. What we are looking at is not an international environment agreement — what we are looking at is nothing other than the biggest industrial and energy revolution that has ever been seen.”

Arjun Appadurai: A Nation of Business Junkies (Anthropology News)

By Anthropology News on November 3, 2011

I first came to this country in 1967. I have been either a crypto-anthropologist or professional anthropologist for most of that time. Still, because I came here with an interest in India and took the path of least resistance in choosing to maintain India as my principal ethnographic referent, I have always been reluctant to offer opinions about life in these United States. I have begun to do so recently, but mainly in occasional blogs, twitter posts and the like. Now seems to be a good time to ponder whether I have anything to offer to public debate about the media in this country. Since I have been teaching for a few years in a distinguished department of media studies, I feel emboldened to offer my thoughts in this new AN Forum.

My examination of changes in the media over the last few decades is not based on a scientific study. I read the New York Times every day, the Wall Street Journal occasionally, and I subscribe to The Atlantic, Harper’s, The New York Review of Books, the Economist, and a variety of academic journals in anthropology and area studies. I get a smattering of other useful media pieces from friends on Facebook and other social media sites. I also use the Internet to keep up with as much as I can from the press in and about India. At various times in the past, I have subscribed to The Nation, Money Magazine, Foreign Policy, the Times Literary supplement and a few other periodicals.

I have long been interested in how culture and economy interact. Today, I want to make an observation about the single biggest change I have seen over my four decades in the United States, which is a growing and now hegemonic domination of the news and of a great deal of opinion, both in print and on television, by business news. Business news was a specialized affair in the late 1960’s, confined to a few magazines such as Money and Fortune, and to newspapers and TV reporters (not channels). Now, it is hard to find anything but business as the topic of news in all media. Consider television: if you spend even three hours surfing between CNN and BBC on any given day ( surfing for news about Libya or about soccer, for example) you will find yourself regularly assaulted by business news, not just from London, New York and Washington, but from Singapore, Hong Kong, Mumbai and many other places. Look at the serious talk shows and chances are that you will find a talking CEO, describing what’s good about his company, what’s bad about the government and how to read his company’s stock prices. Channels like MSNBC are a form of endless, mind-numbing Jerry Lewis telethon about the economy, with more than a hint of the desperation of the Depression era movie “They Shoot Horses Don’t They?”, as they bid the viewer to make insane bets and to mourn the fallen heroes of failed companies and fired CEO’s.

Turn to the newspapers and things get worse. Any reader of the New York Times will find it hard to get away from the business machine. Start with the lead section, and stories about Obama’s economic plans, mad Republican proposals about taxes, the Euro-crisis and the latest bank scandal will assault you. Some relief is provided by more corporate news: the exit of Steve Jobs, the Op-Ed piece about the responsibilities of the super-rich by Warren Buffet, Donald Trump advertising his new line of housewares to go along with his ugly homes and buildings. Turn to the sports section: it is littered with talk of franchises, salaries, trades, owner antics, stadium projects and more. I need hardly say anything about the section on “Business” itself, which has now virtually become redundant. And if you are still thirsty for more business news, check out the “Home”, “Lifestyle” and Real Estate sections for news on houses you can’t afford and mortgage financing gimmicks you have never heard off. Some measure of relief is to be in the occasional “Science Times” and in the NYT Book Review, which do have some pieces which are not primarily about profit, corporate politics or the recession.

The New York Times is not to blame for this. They are the newspaper of “record’ and that means that they reflect broader trends and cannot be blamed for their compliance with bigger trends. Go through the magazines when you take a flight to Detroit or Mumbai and there is again a feast of news geared to the “business traveler”. This is when I catch up on how to negotiate the best deal, why this is the time to buy gold and what software and hardware to use when I make my next presentation to General Electric. These examples could be multiplied in any number of bookstores, newspaper kiosks, airport lounges, park benches and dentist’s offices.

What does all this reflect? Well, we were always told that the business of America is business. But now we are gradually moving into a society in which the business of American life is also business. Who are we now? We have become (in our fantasies) entrepreneurs, start-up heroes, small investors, consumers, home-owners, day-traders, and a gallery of supporting business types, and no longer fathers, mothers, friends or neighbors. Our very citizenship is now defined by business, whether we are winners or losers. Everyone is an expert on pensions, stocks, retirement packages, vacation deals, credit- card scams and more. Meanwhile, as Paul Krugman has argued in a brilliant recent speech to some of his fellow economists, this discipline, especially macro-economics, has lost all its capacities to analyze, define or repair the huge mess we are in.

The gradual transformation of the imagined reader or viewer into a business junkie is a relatively new disease of advanced capitalism in the United States. The avalanche of business knowledge and information dropping on the American middle-classes ought to have helped us predict – or avoid – the recent economic meltdown, based on crazy credit devices, vulgar scams and lousy regulation. Instead it has made us business junkies, ready to be led like sheep to our own slaughter by Wall Street, the big banks and corrupt politicians. The growing hegemony of business news and knowledge in the popular media over the last few decades has produced a collective silence of the lambs. It is time for a bleat or two.

Where Did Global Warming Go? (N.Y. Times)

Uncategorized, , , , , , , , , , , , ,

Published: October 15, 2011

Mark Pernice and Scott Altmann

IN 2008, both the Democratic and Republican candidates for president, Barack Obama and John McCain, warned about man-made global warming and supported legislation to curb emissions. After he was elected, President Obama promised “a new chapter in America’s leadership on climate change,” and arrived cavalry-like at the 2009 United Nations Climate Conference in Copenhagen to broker a global pact.

But two years later, now that nearly every other nation accepts climate change as a pressing problem, America has turned agnostic on the issue.

In the crowded Republican presidential field, most seem to agree with Gov. Rick Perry of Texas that “the science is not settled” on man-made global warming, as he said in a debate last month. Alone among Republicans onstage that night, Jon M. Huntsman Jr. said that he trusted scientists’ view that the problem was real. At the moment, he has the backing of about 2 percent of likely Republican voters.

Though the evidence of climate change has, if anything, solidified, Mr. Obama now talks about “green jobs” mostly as a strategy for improving the economy, not the planet. He did not mention climate in his last State of the Union address. Meanwhile, the administration is fighting to exempt United States airlines from Europe’s new plan to charge them for CO2 emissions when they land on the continent. It also seems poised to approve a nearly 2,000-mile-long pipeline, from Canada down through the United States, that will carry a kind of oil. Extracting it will put relatively high levels of emissions into the atmosphere.

“In Washington, ‘climate change’ has become a lightning rod, it’s a four-letter word,” said Andrew J. Hoffman, director of the University of Michigan’s Erb Institute for Sustainable Development.

Across the nation, too, belief in man-made global warming, and passion about doing something to arrest climate change, is not what it was five years or so ago, when Al Gore’s movie had buzz and Elizabeth Kolbert’s book about climate change, “Field Notes From a Catastrophe,” was a best seller. The number of Americans who believe the earth is warming dropped to 59 percent last year from 79 percent in 2006, according to polling by the Pew Research Group. When the British polling firm Ipsos Mori asked Americans this past summer to list their three most pressing environmental worries, “global warming/climate change” garnered only 27 percent, behind even “overpopulation.”

This fading of global warming from the political agenda is a mostly American phenomenon. True, public enthusiasm for legislation to tackle climate change has flagged somewhat throughout the developed world since the recession of 2008. Nonetheless, in many other countries, legislation to control emissions has rolled out apace. Just last Wednesday, Australia’s House of Representatives passed a carbon tax, which is expected to easily clear the country’s Senate. Europe’s six-year-old carbon emissions trading system continues its yearly expansion. In 2010, India passed a carbon tax on coal. Even China’s newest five-year plan contains a limited pilot cap-and-trade system, under which polluters pay for excess pollution.

The United States is the “one significant outlier” on responding to climate change, according to a recent global research report produced by HSBC, the London-based bank. John Ashton, Britain’s special representative for climate change, said in an interview that “in the U.K., in Europe, in most places I travel to” — but not in the United States — “the starting point for conversation is that this is real, there are clear and present dangers, so let’s get a move on and respond.” After watching the Republican candidates express skepticism about global warming in early September, former President Bill Clinton put it more bluntly, “I mean, it makes us — we look like a joke, right?”

Americans — who produce twice the emissions per capita that Europeans do — are in many ways wired to be holdouts. We prefer bigger cars and bigger homes. We value personal freedom, are suspicious of scientists, and tend to distrust the kind of sweeping government intervention required to confront rising greenhouse gas emissions.

“Climate change presents numerous ideological challenges to our culture and our beliefs,” Professor Hoffman of the Erb Institute says. “People say, ‘Wait a second, this is really going to affect how we live!’ ”

There are, of course, other factors that hardened resistance: America’s powerful fossil-fuel industry, whose profits are bound to be affected by any greater control of carbon emissions; a cold American winter in 2010 that made global warming seem less imminent; and a deep recession that made taxes on energy harder to talk about, and job creation a more pressing issue than the environment — as can be seen in the debate over the pipeline from Canada.

But it is also true that Europe has endured a deep recession and has had mild winters. What’s more, some of the loudest climate deniers are English. Yet the European Union is largely on target to meet its goal of reducing emissions by at least 20 percent over 1990 levels by 2020.

Connie Hedegaard, the European Union’s commissioner on climate action, told me recently: “Look, it was not a piece of cake here either.”

In fact, many countries in Europe have come to see combating climate change and the move to a “greener” economy as about “opportunities rather than costs,” Mr. Ashton said. In Britain, the low-carbon manufacturing sector has been one of the few to grow through the economic slump.

“One thing I’ve been pleasantly surprised about in the E.U. is that despite the economic and financial crisis, the momentum on climate change has more or less continued,” Mr. Ashton said.

And Conservatives, rather than posing an obstacle, are directing aggressive climate policies in much of the world. Before becoming the European Union’s commissioner for climate action, Ms. Hedegaard was a well-known Conservative politician in her native Denmark. In Britain, where a 2008 law required deep cuts in emissions, a coalition Conservative government is now championing a Green Deal.

In the United States, the right wing of the Republican Party has managed to turn skepticism about man-made global warming into a requirement for electability, forming an unlikely triad with antiabortion and gun-rights beliefs. In findings from a Pew poll this spring, 75 percent of staunch conservatives, 63 percent of libertarians and 55 percent of Main Street Republicans said there was no solid evidence of global warming.

“This has become a partisan political issue here in a way it has not elsewhere,” said Andrew Kohut, president of the Pew Research Center. “We are seeing doubts in the U.S. largely because the issue has become a partisan one, with Democrats” — 75 percent of whom say they believe there is strong evidence of climate change — “seeing one thing and Republicans another.”

Europeans understand the challenges in the United States, though they sound increasingly impatient. “We are very much aware of the political situation in the United States and we don’t say ‘do this,’ when we know it can’t get through Congress,” said Ms. Hedegaard, when she was in New York for the United Nations General Assembly last month. But she added:

“O.K. if you can’t commit today, when can you? When are you willing to join in? Australia is making a cap-and-trade system. South Korea is introducing one. New Zealand and the E.U. have it already. So when is the time? That’s the question for the U.S.”

MEANWHILE, in the developing world, emerging economies like India and China are now pursuing aggressive climate policies. “Two years ago the assumption was that the developed world would have to lead, but now China, India and Brazil have jumped in with enthusiasm, and are moving ahead,” said Nick Robins of HSBC Global Research.

Buffeted by two years of treacherous weather that they are less able to handle than richer nations — from floods in India to water shortages in China — developing countries are feeling vulnerable. Scientists agree that extreme weather events will be more severe and frequent on a warming planet, and insurance companies have already documented an increase.

So perhaps it is no surprise that regard for climate change as “a very serious problem” has risen significantly in many developing nations over the past two years. A 2010 Pew survey showed that more than 70 percent of people in China, India and South Korea were willing to pay more for energy in order to address climate change. The number in the United States was 38 percent. China’s 12th five-year plan, for 2011-2015, directs intensive investment to low carbon industries. In contrast, in the United States, there is “no prospect of moving ahead” at a national legislative level, Mr. Robins said, although some state governments are addressing the issue.

In private, scientific advisers to Mr. Obama say he and his administration remain committed to confronting climate change and global warming. But Robert E. O’Connor, program director for decision, risk and management sciences at the National Science Foundation in Washington, said a bolder leader would emphasize real risks that, apparently, now feel distant to many Americans. “If it’s such an important issue, why isn’t he talking about it?”

Why Culture Matters in the Climate Debate (The Yale Forum on Climate Change & The Media)

Uncategorized, , , , , , , , , , , ,

Keith Kloor, October 25, 2011

A new paper argues that climate educators and communicators are ignoring deeply held beliefs that influence climate skepticism.

It is the great riddle of the day in climate circles: Why is public concern about global warming so shallow, and why do widespread doubts about man-made climate change persist?

Everyone seems to have a pet theory. Al Gore blames the media and President Obama. Some green critics argue that Gore should look in the mirror. Let’s not ignore the recession, scholars remind us. Yes, but the lion’s share of blame must go to those “merchants of doubt”, particularly fossil fuel interests, and climate skeptics, plenty others assert. Err, actually, it’s our brain that’s the biggest problem, social scientists now say.

Commentary

Another reason, similar to that last one, is that cultural and religious beliefs predispose many to dismiss evidence that humans can greatly influence the climate. In fact, geographer Simon Donner in a paper published this week in Bulletin of the American Meteorological Society, argues:

“Successful climate change education and outreach programs should be designed to help overcome perceived conflict between climate science and long-held cultural beliefs, drawing upon lessons from communication and education of other potentially divisive subjects like evolution.”

Donner is not the first to try to bridge the gap between science and religion. E.O. Wilson gamely attempted to do so several years ago, with his book, The Creation. In a 2006 interview with NPR, Wilson acknowledged that, “the usual approach of secular science is to marginalize religion” in debates on environmental issues. After the book’s publication, this writer facilitated a lengthy dialogue between Wilson, ecologist Stuart Pimm and leading evangelical Richard Cizik, on areas where science and religion could find common ground. Expanding on that public dialogue has proven difficult. If anything, the polarized political landscape and the continuing climate wars have narrowed the space for science and religion to be reconciled.

Still, those who want to overcome obstacles to climate action should be mindful of culture’s importance, Donner stresses in his paper. He writes that “lingering public uncertainty about anthropogenic climate change may be rooted in an important but largely unrecognized conflict between climate science and some long held beliefs. In many cultures, the weather and climate have historically been viewed as too vast and too grand to be directly influenced by people.”

Donner writes that scholars studying public attitudes on climate change should factor in such cultural worldviews when accounting for climate skepticism. He surmises: “Underlying doubts that human activity can influence the climate may explain some of the malleability of public opinion about the scientific evidence for climate change.”

Donner suggests that climate educators and communicators learn from approaches that have worked in the evolution debate. He informs us:

“Pedagogical research on evolution finds that providing the audience with opportunities to evaluate how their culture or beliefs affect their willingness to accept scientific evidence is more effective than attempting to separate scientific views from religious or cultural views.”

Moreover, Donner argues that “reforming public communication” on climate change “will require humility on the part of scientists and educators.” He concludes:

“Climate scientists, for whom any inherent doubts about the possible extent of human influence on the climate were overcome by years of training in physics and chemistry of the climate system, need to accept that there are rational cultural, religious and historical reasons that the public may fail to believe that anthropogenic climate change is real, let alone that it warrants a policy response. It is unreasonable to expect a lay audience, not armed with the same analytical tools as scientists, to develop lasting acceptance during a one-hour public seminar of a scientific conclusion that runs counters to thousands of years of human belief. Without addressing the common long-standing belief that human activity cannot directly influence the climate, public acceptance of climate change and public engagement on climate solutions will not persist through the next cold winter or the next economic meltdown.”

The intersection where science and religion meet is all too often home to an ugly collision. Donner advises that such crack-ups can and should be avoided in the climate debate.

Can it be done?

Aumento da expectativa de vida faz surgir novos problemas nas pessoas com deficiência mental (FAPESP)

O preço da longevidade

Carlos Fioravanti

As pessoas com deficiência intelectual, que há 40 anos morriam na adolescência, hoje podem viver mais de 60 anos. Como estão vivendo mais, outros problemas orgânicos estão surgindo. Reunidos durante dois dias em agosto na Associação de Paes e Amigos dos Excepcionais (Apae) de São Paulo, médicos e pesquisadores da Universidade Federal de São Paulo (Unifesp) e da Universidade de São Paulo (USP), psicólogos, terapeutas, advogados, assistentes sociais e outros profissionais da saúde reconheceram um dos graves problemas emergentes, a possibilidade de envelhecimento precoce.

Em um levantamento preliminar feito em 2009 em seis instituições da cidade de São Paulo, de um grupo de 373 pessoas com deficiência intelectual (ou DI; a expressão deficiência mental não é mais recomendada) e mais de 30 anos de idade, 192 apresentavam pelo menos três sinais de provável envelhecimento precoce, de acordo com um questionário que avaliava eventuais perdas de memória, de autonomia nas tarefas do dia a dia, de interesse por atividades ou de visão e audição. Para dimensionar esse problema, está sendo preparado um levantamento mais abrangente e detalhado, com cerca de 500 pessoas com DI e idade entre 30 e 59 anos da Grande São Paulo.

Os estudos em andamento são essenciais para “vermos o que pode ser feito, em termos de atendimento médico e de políticas públicas”, diz Regina Leondarides, coordenadora do grupo de estudo de envelhecimento precoce das pessoas com deficiência intelectual, que reúne 10 instituições de atendimento. “Temos muitas políticas de saúde voltadas para a criança, mas as políticas para o envelhecimento estão começando a ser construídas”, comenta Esper Cavalheiro, professor da Unifesp e presidente do conselho científico do Instituto Apae de São Paulo. “Estamos atrasados, em vista do envelhecimento acelerado da população brasileira.”

Um estudo da Espanha publicado em 2008 indicou que as pessoas com DI envelhecem prematuramente – as com síndrome de Down, de modo mais intenso. Para chegar a essas conclusões, os pesquisadores acompanharam a saúde de 238 pessoas com DI e mais de 40 anos de idade durante cinco anos. Não se trata, aparentemente, de um fenômeno inevitável. O envelhecimento precoce das pessoas com DI leve e moderada resulta da falta de programas de promoção de saúde e do acesso reduzido a serviços médicos e sociais. As pessoas com DI se mostraram com maior tendência à obesidade (apenas 25% tinham peso considerado normal), à hipertensão arterial (25% do total) e a distúrbios metabólicos, como diabetes e hipotireoidismo (10% do total).

“O envelhecimento precoce, se confirmado, pode ter causas genéticas ou ambientais, independentemente da deficiência intelectual”, comenta Dalci Santos, gerente do Instituto Apae de São Paulo. Matemática de formação, com doutorado em andamento na Unifesp, ela acrescenta: “Não conseguiremos avançar muito até esclarecermos melhor a origem das deficiências intelectuais”. As causas podem ser genéticas, como na síndrome de Down, ou ambientais (causas não genéticas), incluindo infecções, baixa oxigenação do cérebro do feto, alcoolismo, radiação, intoxicação por chumbo durante a gravidez ou prematuridade – muitas vezes, vários fatores em conjunto.

Causas ambientais ou genéticas
Em um artigo no primeiro número da Revista de Deficiência Intelectual DI, publicação do Instituto Apae lançada em outubro, João Monteiro de Pina-Neto, médico geneticista da Faculdade de Medicina de Ribeirão Preto da USP, apresenta os resultados de um estudo sobre as causas da deficiência intelectual em 200 pessoas atendidas nas Apaes de Altinópolis e Serrana, dois municípios da região de Ribeirão Preto. Esse estudo faz parte de um levantamento maior, com cerca de mil pessoas com DI atendidas em quatro Apaes, que Pina-Neto e sua equipe pretendem concluir em meados de 2012. Os resultados obtidos até agora indicam o predomínio de causas ambientais (42,5% do total), seguidas pelas genéticas (29%) e indeterminadas (20%).

Um estudo similar feito com 10 mil pessoas na Carolina do Sul, Estados Unidos, apresentou o mesmo percentual de causas genéticas, mas apenas 18% de causas ambientais e 56% de causas desconhecidas. Alguns contrastes chamam a atenção. Enquanto a deficiência intelectual causada por falta de oxigenação cerebral responde por 5% do total das causas de DI nos Estados Unidos, em São Paulo é 16,5%; a prematuridade, de 5% nos Estados Unidos, foi de 14,5% no estudo paulista; o efeito das infecções, de 5%, é quase o dobro aqui, 9%.

A conclusão que emerge dessa comparação é que o número de nascimentos de bebês com DI poderia ser reduzido por meio de algumas medidas preventivas. “Melhorar o atendimento pré-natal e a qualidade do parto são uma prioridade”, ressalta Pina-Neto. “Ainda temos casos de deficiência causada por sífilis, rubéola ou toxoplasmose contraída durante a gestação e meningites pós-natais”, lamenta. Segundo ele, outro problema que pode ser controlado é o alcoolismo. “De 20% a 30% das mulheres da região de Ribeirão Preto consomem bebida alcoólica em excesso e, como resultado, de cada 100 gravidezes, nasce uma criança com DI causada por síndrome alcoólica fetal”, diz ele. “Não fazemos ainda a adequada prevenção das causas da deficiência intelectual.”

As causas genéticas podem ser controladas, já que o risco de uma criança nascer com síndrome de Down aumenta muito com a idade dos pais. “As mulheres estão tendo filhos após os 35 anos de idade, portanto mais propen­sas a terem filhos com Down, e os homens estão se casando várias vezes, tendo filhos em cada ca­samento”, diz Pina-Neto. Segundo ele, homens estéreis que procuram as clínicas de reprodução deveriam ser mais informados sobre a possibilidade de terem alterações genéticas que podem ser transmitidas aos filhos caso se tornem férteis.

As pessoas com DI apresentam capacidade de raciocínio bastante abaixo da média e limitações para aprender, se cuidar ou se comunicar com outras, mas atualmente são muito mais integradas socialmente, autônomas e produtivas, com mais oportunidades para expressar a criatividade do que há algumas décadas. Frequentam escolas regulares, com outras crianças e adultos, participam de competições esportivas e conquistam mais postos de mercado de trabalho. Crianças e adultos com DI não vão mais à Apae de São Paulo para aprender todo dia, mas aparecem algumas vezes por semana para atendimento educacional especializado ou para consultas médicas. O serviço de apoio ao envelhecimento atende 132 pessoas com idade entre 30 e 67 anos.

Ainda há muitas dúvidas sobre como lidar com os novos problemas. Crianças e adultos com de­­­­ficiência precisam de hábitos e horários para se sentir calmos e confortáveis. Ao mesmo tempo, hábitos imutáveis podem favorecer o surgimento da doença de Alzheimer, doença neurológi­ca que se agrava com o envelhecimento. Vem daí um impasse: manter a rotina inalterada poderia alimentar a propensão ao Alzheimer, mas quebrar a rotina pode ser perturbador.

Propensão ao alzheimer
O cérebro das pessoas com Down pode exibir um dos sinais típicos do Alzheimer: o acúmulo de placas amiloides, que dificultam o funcionamento adequado dos neurônios. Uma equipe da Universidade da Califórnia em Los Angeles, Estados Unidos, encontrou placas amiloides em quantidade mais elevada no cérebro de pessoas com Down do que em pessoas com Alzheimer já diagnosticado e em pessoas normais.

“Os sinais biológicos de Alzheimer podem surgir antes dos sinais clínicos”, observa Orestes Forlenza, professor da Faculdade de Medicina da USP. “Ter amiloide não significa ter demência futura. Qual a melhor intervenção futura? Não sabemos. Talvez via nutrição ou atividade física seja mais seguro do que por medicamentos.” Ira Lott e sua equipe da Universidade da Califórnia em Irvine fizeram um estudo duplo-cego durante dois anos com 53 pessoas com síndrome de Down para ver se a complementação da dieta com compostos antioxidantes poderia melhorar o funcionamento mental ou estabilizar a perda da capacidade cognitiva. Os resultados, publicados em agosto na American Journal of Medical Genetics, indicaram que não.

Esper Cavalheiro apresentou três perguntas ainda sem resposta. De que modo as alterações próprias do envelhecimento, como as doenças cardiovasculares, diabetes e câncer, se apresentam nas pessoas com DI? Como alterações frequentes nessas pessoas, a exemplo de demências e osteoporose, se comportam no envelhecimento? Os medicamentos usados para tratar hipertensão, diabetes e outras doenças típicas do envelhecimento funcionam nas pessoas com DI do mesmo modo que em outros indivíduos?

Outra dúvida: as estratégias de controle dos fatores de risco de doenças cardiovasculares recomendadas para pessoas normais, como o estímulo a atividades físicas, têm o mesmo impacto sobre a saúde das pessoas com e sem deficiência intelectual? “Supomos que sim, mas não sabemos ao certo”, diz Ricardo Nitrini, da USP.

Segundo Cavalheiro, as pessoas com DI com 65 anos ou mais correspondiam a 4% da população total no Censo de 2000; hoje respondem por 5,5% da população total. “Não podemos nos contentar apenas com estatísticas e diagnósticos”, alerta. “Temos de enfrentar esse problema com rapidez. Quanto mais gente dialogando e pensando nesses problemas, melhor.”

Castles in the Desert: Satellites Reveal Lost Cities of Libya (Science Daily)

Uncategorized, , , ,

ScienceDaily (Nov. 7, 2011) — Satellite imagery has uncovered new evidence of a lost civilisation of the Sahara in Libya’s south-western desert wastes that will help re-write the history of the country. The fall of Gaddafi has opened the way for archaeologists to explore the country’s pre-Islamic heritage, so long ignored under his regime.

Using satellites and air-photographs to identify the remains in one of the most inhospitable parts of the desert, a British team has discovered more than 100 fortified farms and villages with castle-like structures and several towns, most dating between AD 1-500.

These “lost cities” were built by a little-known ancient civilisation called the Garamantes, whose lifestyle and culture was far more advanced and historically significant than the ancient sources suggested.

The team from the University of Leicester has identified the mud brick remains of the castle-like complexes, with walls still standing up to four metres high, along with traces of dwellings, cairn cemeteries, associated field systems, wells and sophisticated irrigation systems. Follow-up ground survey earlier this year confirmed the pre-Islamic date and remarkable preservation.

“It is like someone coming to England and suddenly discovering all the medieval castles. These settlements had been unremarked and unrecorded under the Gaddafi regime,” says the project leader David Mattingly FBA, Professor of Roman Archaeology at the University of Leicester.

“Satellite imagery has given us the ability to cover a large region. The evidence suggests that the climate has not changed over the years and we can see that this inhospitable landscape with zero rainfall was once very densely built up and cultivated. These are quite exceptional ancient landscapes, both in terms of the range of features and the quality of preservation,” says Dr Martin Sterry, also of the University of Leicester, who has been responsible for much of the image analysis and site interpretation.

The findings challenge a view dating back to Roman accounts that the Garamantes consisted of barbaric nomads and troublemakers on the edge of the Roman Empire.

“In fact, they were highly civilised, living in large-scale fortified settlements, predominantly as oasis farmers. It was an organised state with towns and villages, a written language and state of the art technologies. The Garamantes were pioneers in establishing oases and opening up Trans-Saharan trade,” Professor Mattingly said.

The professor and his team were forced to evacuate Libya in February when the anti-Gaddafi revolt started, but hope to be able to return to the field as soon as security is fully restored. The Libyan antiquities department, badly under-resourced under Gaddafi, is closely involved in the project. Funding for the research has come from the European Research Council who awarded Professor Mattingly an ERC Advanced Grant of nearly 2.5m euros, the Leverhulme Trust, the Society for Libyan Studies and the GeoEye Foundation.

“It is a new start for Libya’s antiquities service and a chance for the Libyan people to engage with their own long-suppressed history,” says Professor Mattingly.

“These represent the first towns in Libya that weren’t the colonial imposition of Mediterranean people such as the Greeks and Romans. The Garamantes should be central to what Libyan school children learn about their history and heritage.”

Desafios do “tsunami de dados” (FAPESP)

Lançado pelo Instituto Microsoft Research-FAPESP de Pesquisas em TI, o livro O Quarto Paradigma debate os desafios da eScience, nova área dedicada a lidar com o imenso volume de informações que caracteriza a ciência atual

07/11/2011

Por Fábio de Castro

Agência FAPESP – Se há alguns anos a falta de dados limitava os avanços da ciência, hoje o problema se inverteu. O desenvolvimento de novas tecnologias de captação de dados, nas mais variadas áreas e escalas, tem gerado um volume tão imenso de informações que o excesso se tornou um gargalo para o avanço científico.

Nesse contexto, cientistas da computação têm se unido a especialistas de diferentes áreas para desenvolver novos conceitos e teorias capazes de lidar com a enxurrada de dados da ciência contemporânea. O resultado é chamado de eScience.

Esse é o tema debatido no livro O Quarto Paradigma – Descobertas científicas na era da eScience, lançado no dia 3 de novembro pelo Instituto Microsoft Research-FAPESP de Pesquisas em TI.

Organizado por Tony Hey, Stewart Tansley, Kristin Tolle – todos da Microsoft Research –, a publicação foi lançada na sede da FAPESP, em evento que contou com a presença do diretor científico da Fundação, Carlos Henrique de Brito Cruz.

Durante o lançamento, Roberto Marcondes Cesar Jr., do Instituto de Matemática e Estatística (IME) da Universidade de São Paulo (USP), apresentou a palestra “eScience no Brasil”. “O Quarto Paradigma: computação intensiva de dados avançando a descoberta científica” foi o tema da palestra de Daniel Fay, diretor de Terra, Energia e Meio Ambiente da MSR.

Brito Cruz destacou o interesse da FAPESP em estimular o desenvolvimento da eScience no Brasil. “A FAPESP está muito conectada a essa ideia, porque muitos dos nossos projetos e programas apresentam essa necessidade de mais capacidade de gerenciar grandes conjuntos de dados. O nosso grande desafio está na ciência por trás dessa capacidade de lidar com grandes volumes de dados”, disse.

Iniciativas como o Programa FAPESP de Pesquisa sobre Mudanças Climáticas Globais (PFPMCG), o BIOTA-FAPESP e o Programa FAPESP de Pesquisa em Bioenergia (BIOEN) são exemplos de programas que têm grande necessidade de integrar e processar imensos volumes de dados.

“Sabemos que a ciência avança quando novos instrumentos são disponibilizados. Por outro lado, os cientistas normalmente não percebem o computador como um novo grande instrumento que revoluciona a ciência. A FAPESP está interessada em ações para que a comunidade científica tome consciência de que há grandes desafios na área de eScience”, disse Brito Cruz.

O livro é uma coleção de 26 ensaios técnicos divididos em quatro seções: “Terra e meio ambiente”, “Saúde e bem-estar”, “Infraestrutura científica” e “Comunicação acadêmica”.

“O livro fala da emergência de um novo paradigma para as descobertas científicas. Há milhares de anos, o paradigma vigente era o da ciência experimental, fundamentada na descrição de fenômenos naturais. Há algumas centenas de anos, surgiu o paradigma da ciência teórica, simbolizado pelas leis de Newton. Há algumas décadas, surgiu a ciência computacional, simulando fenômenos complexos. Agora, chegamos ao quarto paradigma, que é o da ciência orientada por dados”, disse Fay.

Com o advento do novo paradigma, segundo ele, houve uma mudança completa na natureza da descoberta científica. Entraram em cena modelos complexos, com amplas escalas espaciais e temporais, que exigem cada vez mais interações multidisciplinares.

“Os dados, em quantidade incrível, são provenientes de diferentes fontes e precisam também de abordagem multidisciplinar e, muitas vezes, de tratamento em tempo real. As comunidades científicas também estão mais distribuídas. Tudo isso transformou a maneira como se fazem descobertas”, disse Fay.

A ecologia, uma das áreas altamente afetadas pelos grandes volumes de dados, é um exemplo de como o avanço da ciência, cada vez mais, dependerá da colaboração entre pesquisadores acadêmicos e especialistas em computação.

“Vivemos em uma tempestade de sensoriamento remoto, sensores terrestres baratos e acesso a dados na internet. Mas extrair as variáveis que a ciência requer dessa massa de dados heterogêneos continua sendo um problema. É preciso ter conhecimento especializado sobre algoritmos, formatos de arquivos e limpeza de dados, por exemplo, que nem sempre é acessível para o pessoal da área de ecologia”, explicou.

O mesmo ocorre em áreas como medicina e biologia – que se beneficiam de novas tecnologias, por exemplo, em registros de atividade cerebral, ou de sequenciamento de DNA – ou a astronomia e física, à medida que os modernos telescópios capturam terabytes de informação diariamente e o Grande Colisor de Hádrons (LHC) gera petabytes de dados a cada ano.

Instituto Virtual

Segundo Cesar Jr., a comunidade envolvida com eScience no Brasil está crescendo. O país tem 2.167 cursos de sistemas de informação ou engenharia e ciências da computação. Em 2009, houve 45 mil formados nessas áreas e a pós-graduação, entre 2007 e 2009, tinha 32 cursos, mil orientadores, 2.705 mestrandos e 410 doutorandos.

“A ciência mudou do paradigma da aquisição de dados para o da análise de dados. Temos diferentes tecnologias que produzem terabytes em diversos campos do conhecimento e, hoje, podemos dizer que essas áreas têm foco na análise de um dilúvio de dados”, disse o membro da Coordenação da Área de Ciência e Engenharia da Computação da FAPESP.

Em 2006, a Sociedade Brasileira de Computação (SBC) organizou um encontro a fim de identificar os problemas-chave e os principais desafios para a área. Isso levou a diferentes propostas para que o Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) criasse um programa específico para esse tipo de problema.

“Em 2009, realizamos uma série de workshops na FAPESP, reunindo, para discutir essa questão, cientistas de áreas como agricultura, mudanças climáticas, medicina, transcriptômica, games, governo eletrônico e redes sociais. A iniciativa resultou em excelentes colaborações entre grupos de cientistas com problemas semelhantes e originou diversas iniciativas”, disse César Jr.

As chamadas do Instituto Microsoft Research-FAPESP de Pesquisas em TI, segundo ele, têm sido parte importante do conjunto de iniciativas para promover a eScience, assim como a organização da Escola São Paulo de Ciência Avançada em Processamento e Visualização de Imagens Computacionais. Além disso, a FAPESP tem apoiado diversos projetos de pesquisa ligados ao tema.

“A comunidade de eScience em São Paulo tem trabalhado com profissionais de diversas áreas e publicado em revistas de várias delas. Isso é indicação de qualidade adquirida pela comunidade para encarar o grande desafio que teremos nos próximos anos”, disse César Jr., que assina o prefácio da edição brasileira do livro.

Scientists Find Evidence of Ancient Megadrought in Southwestern U.S. (Science Daily)

Uncategorized, , , , , , , ,

ScienceDaily (Nov. 6, 2011) — A new study at the the University of Arizona’s Laboratory of Tree-Ring Research has revealed a previously unknown multi-decade drought period in the second century A.D. The findings give evidence that extended periods of aridity have occurred at intervals throughout our past.

Almost 900 years ago, in the mid-12th century, the southwestern U.S. was in the middle of a multi-decade megadrought. It was the most recent extended period of severe drought known for this region. But it was not the first.

The second century A.D. saw an extended dry period of more than 100 years characterized by a multi-decade drought lasting nearly 50 years, says a new study from scientists at the University of Arizona.

UA geoscientists Cody Routson, Connie Woodhouse and Jonathan Overpeck conducted a study of the southern San Juan Mountains in south-central Colorado. The region serves as a primary drainage site for the Rio Grande and San Juan rivers.

“These mountains are very important for both the San Juan River and the Rio Grande River,” said Routson, a doctoral candidate in the environmental studies laboratory of the UA’s department of geosciences and the primary author of the study, which is upcoming in Geophysical Research Letters.

The San Juan River is a tributary for the Colorado River, meaning any climate changes that affect the San Juan drainage also likely would affect the Colorado River and its watershed. Said Routson: “We wanted to develop as long a record as possible for that region.”

Dendrochronology is a precise science of using annual growth rings of trees to understand climate in the past. Because trees add a normally clearly defined growth ring around their trunk each year, counting the rings backwards from a tree’s bark allows scientists to determine not only the age of the tree, but which years were good for growth and which years were more difficult.

“If it’s a wet year, they grow a wide ring, and if it’s a dry year, they grow a narrow ring,” said Routson. “If you average that pattern across trees in a region you can develop a chronology that shows what years were drier or wetter for that particular region.”

Darker wood, referred to as latewood because it develops in the latter part of the year at the end of the growing season, forms a usually distinct boundary between one ring and the next. The latewood is darker because growth at the end of the growing season has slowed and the cells are more compact.

To develop their chronology, the researchers looked for indications of climate in the past in the growth rings of the oldest trees in the southern San Juan region. “We drove around and looked for old trees,” said Routson.

Literally nothing is older than a bristlecone pine tree: The oldest and longest-living species on the planet, these pine trees normally are found clinging to bare rocky landscapes of alpine or near-alpine mountain slopes. The trees, the oldest of which are more than 4,000 years old, are capable of withstanding extreme drought conditions.

“We did a lot of hiking and found a couple of sites of bristlecone pines, and one in particular that we honed in on,” said Routson.

To sample the trees without damaging them, the dendrochronologists used a tool like a metal screw that bores a tiny hole in the trunk of the tree and allows them to extract a sample, called a core. “We take a piece of wood about the size and shape of a pencil from the tree,” explained Routson.

“We also sampled dead wood that was lying about the land. We took our samples back to the lab where we used a visual, graphic technique to match where the annual growth patterns of the living trees overlap with the patterns in the dead wood. Once we have the pattern matched we measure the rings and average these values to generate a site chronology.”

“In our chronology for the south San Juan mountains we created a record that extends back 2,200 years,” said Routson. “It was pretty profound that we were able to get back that far.”

The chronology extends many years earlier than the medieval period, during which two major drought events in that region already were known from previous chronologies.

“The medieval period extends roughly from 800 to 1300 A.D.,” said Routson. “During that period there was a lot of evidence from previous studies for increased aridity, in particular two major droughts: one in the middle of the 12th century, and one at the end of the 13th century.”

“Very few records are long enough to assess the global conditions associated with these two periods of Southwestern aridity,” said Routson. “And the available records have uncertainties.”

But the chronology from the San Juan bristlecone pines showed something completely new:

“There was another period of increased aridity even earlier,” said Routson. “This new record shows that in addition to known droughts from the medieval period, there is also evidence for an earlier megadrought during the second century A.D.”

“What we can see from our record is that it was a period of basically 50 consecutive years of below-average growth,” said Routson. “And that’s within a much broader period that extends from around 124 A.D. to 210 A.D. — about a 100-year-long period of dry conditions.”

“We’re showing that there are multiple extreme drought events that happened during our past in this region,” said Routson. “These megadroughts lasted for decades, which is much longer than our current drought. And the climatic events behind these previous dry periods are really similar to what we’re experiencing today.”

The prolonged drought in the 12th century and the newly discovered event in the second century A.D. may both have been influenced by warmer-than-average Northern Hemisphere temperatures, Routson said: “The limited records indicate there may have been similar La Nina-like background conditions in the tropical Pacific Ocean, which are known to influence modern drought, during the two periods.”

Although natural climate variation has led to extended dry periods in the southwestern U.S. in the past, there is reason to believe that human-driven climate change will increase the frequency of extreme droughts in the future, said Routson. In other words, we should expect similar multi-decade droughts in a future predicted to be even warmer than the past.

Routson’s research is funded by fellowships from the National Science Foundation, the Science Foundation Arizona and the Climate Assessment of the Southwest. His advisors, Woodhouse of the School of Geography and Development and Overpeck of the department of geosciences and co-director of the UA’s Institute of the Environment, are co-authors of the study.

Copyright: A Conceptual Battle in a Digital Age (Science Daily)

Uncategorized, , , , ,

ScienceDaily (Nov. 3, 2011) — What is it about copyright that doesn’t work in the digital society? Why do millions of people think it’s OK to break the law when it comes to file sharing in particular? Sociology of law researcher Stefan Larsson from Lund University believes that legal metaphors and old-fashioned mindsets contribute to the confusion and widening gaps between legislation and the prevailing norms.

Our language is made up of metaphors, even in our legal texts. Stefan Larsson has studied what consequences this has when digital phenomena, such as file sharing and downloading, are limited by descriptions intended for an analogue world. “When legal arguments equate file sharing with theft of physical objects, it sometimes becomes problematic,” says Stefan Larsson, who doesn’t think it is possible to equate an illegal download with theft of a physical object, as has been done in the case against The Pirate Bay.

Using the compensation model employed in the case against The Pirate Bay, the total value of such a site could be calculated at over SEK 600 billion. This is almost as much as Sweden’s national budget, says Stefan Larsson. The prosecutor in the Pirate Bay case chose to pursue a smaller number of downloads and the sum of the fines therefore never reached these proportions.

In Stefan Larsson’s view, the word ‘copies’ is a hidden legal metaphor that causes problematic ideas in the digital society. For example, copyright does not take into account that a download does not result in the owner losing his or her own copy. Neither is it possible to equate number of downloads with lost income for the copyright holder, since it is likely that people download a lot more than they would purchase in a shop.

Other metaphors that are used for downloading are infringement, theft and piracy. “The problem is that these metaphors make us equate copyright with ownership of physical property,” says Stefan Larsson.

Moreover, there are underlying mindsets which guide the whole of copyright, according to Stefan Larsson. One such mindset is the idea that creation is a process undertaken by sole geniuses and not so much in a cultural context. In Stefan Larsson’s view, this has the unfortunate consequence of making stronger copyright protection with longer duration and a higher degree of legal enforcement appear reasonable. The problem is that it is based on a misconception of how a lot of things are created, says Stefan Larsson: “Borrowing and drawing inspiration from other artists is essential to a lot of creative activity. This is the case both online and offline.”

Stefan Larsson has also studied the consequences when public perception of the law, or social norms, is not in line with what the law says. One consequence is that the State needs to exercise more control and issue more severe penalties in order to ensure that the law is followed. The European trend in copyright law is heading in this direction. Among other things, it is being made easier to track what individuals do on the Internet. This means that the integrity of the many is being eroded to benefit the interests of a few, according to Stefan Larsson: “When all’s said and done, it is about what we want the Internet to be. The fight for this is taking place, at least partially, through metaphorical expressions for underlying conceptions, but also through practical action on the role of anonymity online.”

Stefan Larsson’s thesis is entitled Metaphors and Norms – Understanding Copyright Law in a Digital Society.

The Human Cause of Climate Change: Where Does the Burden of Proof Lie? (Science Daily)

Uncategorized, , , , , , , , , ,

ScienceDaily (Nov. 3, 2011) — The debate may largely be drawn along political lines, but the human role in climate change remains one of the most controversial questions in 21st century science. Writing in WIREs Climate Change Dr Kevin Trenberth, from the National Center for Atmospheric Research, argues that the evidence for anthropogenic climate change is now so clear that the burden of proof should lie with research which seeks to disprove the human role.

In response to Trenberth’s argument a second review, by Dr Judith Curry, focuses on the concept of a ‘null hypothesis’ the default position which is taken when research is carried out. Currently the null hypothesis for climate change attribution research is that humans have no influence.

“Humans are changing our climate. There is no doubt whatsoever,” said Trenberth. “Questions remain as to the extent of our collective contribution, but it is clear that the effects are not small and have emerged from the noise of natural variability. So why does the science community continue to do attribution studies and assume that humans have no influence as a null hypothesis?”

To show precedent for his position Trenberth cites the 2007 report by the Intergovernmental Panel on Climate Change which states that global warming is “unequivocal,” and is “very likely” due to human activities.

Trenberth also focused on climate attribution studies which claim the lack of a human component, and suggested that the assumptions distort results in the direction of finding no human influence, resulting in misleading statements about the causes of climate change that can serve to grossly underestimate the role of humans in climate events.

“Scientists must challenge misconceptions in the difference between weather and climate while attribution studies must include a human component,” concluded Trenberth. “The question should no longer be is there a human component, but what is it?”

In a second paper Dr Judith Curry, from the Georgia Institute of Technology, questions this position, but argues that the discussion on the null hypothesis serves to highlight fuzziness surrounding the many hypotheses related to dangerous climate change.

“Regarding attribution studies, rather than trying to reject either hypothesis regardless of which is the null, there should be a debate over the significance of anthropogenic warming relative to forced and unforced natural climate variability,” said Curry.

Curry also suggested that the desire to reverse the null hypothesis may have the goal of seeking to marginalise the climate sceptic movement, a vocal group who have challenged the scientific orthodoxy on climate change.

“The proponents of reversing the null hypothesis should be careful of what they wish for,” concluded Curry. “One consequence may be that the scientific focus, and therefore funding, would also reverse to attempting to disprove dangerous anthropogenic climate change, which has been a position of many sceptics.”

“I doubt Trenberth’s suggestion will find much support in the scientific community,” said Professor Myles Allen from Oxford University, “but Curry’s counter proposal to abandon hypothesis tests is worse. We still have plenty of interesting hypotheses to test: did human influence on climate increase the risk of this event at all? Did it increase it by more than a factor of two?”

Aloizio Mercadante e o governador do Ceará, Cid Gomes, inauguraram o Radar Meteorológico Banda-S, em Quixeramobim (CE). Equipamento ajudará na previsão de secas e cheias.

Previsão de secas e cheias, mudanças climáticas e todos os eventos ligados a meteorologia passam a ser informados pela Fundação Cearense de Meteorologia e Recursos Hídricos (Funceme) com mais previsão, já que agora o órgão conta com um novo equipamento para captação dessas informações.

O novo Radar Meteorológico Banda-S foi inaugurado nesta quinta-feira (3) pelo governador Cid Gomes e o ministro da Ciência e Tecnologia, Aloizio Mercadante. Localizado no Morro de Santa Maria, em Quixeramobim, no Sertão Central, o equipamento vai funcionar como parte da Rede Cearense de Radares (RCR), por meio da integração com o Radar Doppler de Banda X instalado em Fortaleza. “Parece um equipamento aparentemente simples, mas por trás existe uma utilidade inimaginável. A tecnologia pode ser um aliado na melhoria da qualidade de vida da população, que é o nosso compromisso”, destacou Cid Gomes durante a inauguração.

Segundo explicou o governador, o novo equipamento pode informar condições climáticas bem específicas, como por exemplo “que no município de Nova Olinda, no Cariri, choveu cinco milímetros”, exemplificou. “Na medida que uma informação dessas é casada com outras, isso vai ajudar a diagnosticar por exemplo um período de seca ou de cheias. Somos um estado com quase 300 mil pequenos agricultores, e eles precisam de informações concretas para cuidar da colheita. E nisso o Radar vai ser bastante útil”, ressaltou Cid Gomes.

O Radar Banda-S tem capacidade para estimar uma precipitação dentro de um raio de 200 quilômetros. Além disso, pode fazer o monitoramento de sistemas meteorológicos que atuam em um alcance de até 400 quilômetros. Por sua capacidade e localização, também será possível obter informações não só do Ceará, como de vários estados nordestinos. “Esse é um instrumento de planejamento agrícola que vai beneficiar também muitos estados do Nordeste, como Paraíba, Pernambuco, Piauí e Rio Grande do Norte”, lembrou Aloizio Mercadante. O ministro também ressaltou sua importância na prevenção de desastres naturais, como longos períodos de seca ou chuvas bem acima da média. “Precisamos entender porque esses eventos acontecem e prevenir as ações que as mudanças climáticas podem causar”, explicou Mercadante.

Para a instalação do Radar Meteorológico Banda-S foram investidos R$ 14 milhões, sendo R$ 10 milhões partiram do Governo Federal, por meio do Ministério da Ciência e Tecnologia e Inovação (MCTI) e R$ 4 milhões do governo do estado do Ceará. Do total, R$ 12 milhões foram utilizados para a compra do equipamento e o restante (R$ 2 milhões) para a melhoria dos acessos ao local (construção de vias) e alimentação energética.

Segundo lembrou o secretário estadual da Ciência e Tecnologia, René Barreira, a instalação do Radar partiu de uma emenda de Ciro Gomes quando deputado federal, que aliado a sensibilidade do ex-presidente Lula, tornou possível a obra. “Com esse importante equipamento vamos ter um zoneamento agrícola e um controle mais efetivo e técnico dos eventos de grande risco”, ressaltou o secretário.

The Mental Time Travel Of Animals (NPR)

Don't underestimate the crow.

Without a trace of agitation, the male chimpanzee piles up stones in small caches within his enclosure. He does this in the morning, before zoo visitors arrive. Hours later, in an aroused state, the ape hurls the stones at people gathering to watch him.

A detailed report by Mathias Osvath concluded that the ape had planned ahead strategically for the future. It is exactly this feat of mental time travel that psychologist Michael C. Corballis, in his book The Recursive Mind: The Origins of Human Language, Thought, and Civilization, claims is beyond the reach of nonhuman animals. Last week, my review of Corballis’s book appeared in the Times Literary Supplement.

Corballis suggests that mental time travel is one of two human ways of thinking that propelled our species into a unique cognitive status. (The other, theory of mind, I won’t deal with here.)

During mental time travel, we insert into our present consciousness an experience that we’ve had in the past or that we imagine for ourselves in the future. Corballis calls this ability mental recursion, and he’s right that we humans do it effortlessly. When we daydream at work about last weekend’s happy times with family and friends, or anticipate tonight’s quiet evening with a book, we engage in mental time travel.

Our highly elaborated ability to insert the past or future recursively into our thinking may play a role in the evolution of human civilization, as Corballis claims. But Corballis’s argument is weakened because he dismisses other animals’ mental capacities far too readily.

It’s not only one chimpanzee in a Swedish zoo who makes me think so.

When our pets grieve, as I wrote about in this space recently, they hold in their mind some memory of the past that causes them to miss a companion.

New research on the pattern of food storage by Eurasian jays indicates that these birds think ahead about what specific foods they will want in the future.

When apes (chimpanzees) and corvids (crows and ravens) make tools to obtain food, they too think ahead to a goal, even as they fashion a tool to solve the problem before them.

In the NATURE documentary film A Murder of Crows, a New Caledonian crow solves a three-part tool-using problem totally new to him (or to any other crow). As one researcher put it, the bird thinks “three chess moves into the future” as he finds one tool that allows him to get another tool that he uses finally to procure food.

Have a look at this crow’s stunning problem-solving here. The experimental footage begins at 16:30, but starting at 13:00 offers good context. And the entire film is a delight.

Fraud Case Seen as a Red Flag for Psychology Research (N.Y. Times)

Published: November 2, 2011

A well-known psychologist in the Netherlands whose work has been published widely in professional journals falsified data and made up entire experiments, an investigating committee has found. Experts say the case exposes deep flaws in the way science is done in a field,psychology, that has only recently earned a fragile respectability.

The psychologist, Diederik Stapel, of Tilburg University, committed academic fraud in “several dozen” published papers, many accepted in respected journals and reported in the news media, according to a report released on Monday by the three Dutch institutions where he has worked: the University of Groningen, the University of Amsterdam, and Tilburg. The journal Science, which published one of Dr. Stapel’s papers in April, posted an “editorial expression of concern” about the research online on Tuesday.

The scandal, involving about a decade of work, is the latest in a string of embarrassments in a field that critics and statisticians say badly needs to overhaul how it treats research results. In recent years, psychologists have reported a raft of findings on race biases, brain imaging and even extrasensory perception that have not stood up to scrutiny. Outright fraud may be rare, these experts say, but they contend that Dr. Stapel took advantage of a system that allows researchers to operate in near secrecy and massage data to find what they want to find, without much fear of being challenged.

“The big problem is that the culture is such that researchers spin their work in a way that tells a prettier story than what they really found,” said Jonathan Schooler, a psychologist at the University of California, Santa Barbara. “It’s almost like everyone is on steroids, and to compete you have to take steroids as well.”

In a prolific career, Dr. Stapel published papers on the effect of power on hypocrisy, on racial stereotyping and on how advertisements affect how people view themselves. Many of his findings appeared in newspapers around the world, including The New York Times, which reported in December on his study about advertising and identity.

In a statement posted Monday on Tilburg University’s Web site, Dr. Stapel apologized to his colleagues. “I have failed as a scientist and researcher,” it read, in part. “I feel ashamed for it and have great regret.”

More than a dozen doctoral theses that he oversaw are also questionable, the investigators concluded, after interviewing former students, co-authors and colleagues. Dr. Stapel has published about 150 papers, many of which, like the advertising study, seem devised to make a splash in the media. The study published in Science this year claimed that white people became more likely to “stereotype and discriminate” against black people when they were in a messy environment, versus an organized one. Another study, published in 2009, claimed that people judged job applicants as more competent if they had a male voice. The investigating committee did not post a list of papers that it had found fraudulent.

Dr. Stapel was able to operate for so long, the committee said, in large measure because he was “lord of the data,” the only person who saw the experimental evidence that had been gathered (or fabricated). This is a widespread problem in psychology, said Jelte M. Wicherts, a psychologist at the University of Amsterdam. In a recent survey, two-thirds of Dutch research psychologists said they did not make their raw data available for other researchers to see. “This is in violation of ethical rules established in the field,” Dr. Wicherts said.

In a survey of more than 2,000 American psychologists scheduled to be published this year, Leslie John of Harvard Business School and two colleagues found that 70 percent had acknowledged, anonymously, to cutting some corners in reporting data. About a third said they had reported an unexpected finding as predicted from the start, and about 1 percent admitted to falsifying data.

Also common is a self-serving statistical sloppiness. In an analysis published this year, Dr. Wicherts and Marjan Bakker, also at the University of Amsterdam, searched a random sample of 281 psychology papers for statistical errors. They found that about half of the papers in high-end journals contained some statistical error, and that about 15 percent of all papers had at least one error that changed a reported finding — almost always in opposition to the authors’ hypothesis.

The American Psychological Association, the field’s largest and most influential publisher of results, “is very concerned about scientific ethics and having only reliable and valid research findings within the literature,” said Kim I. Mills, a spokeswoman. “We will move to retract any invalid research as such articles are clearly identified.”

Researchers in psychology are certainly aware of the issue. In recent years, some have mocked studies showing correlations between activity on brain images and personality measures as “voodoo” science, and a controversy over statistics erupted in January after The Journal of Personality and Social Psychology accepted a paper purporting to show evidence of extrasensory perception. In cases like these, the authors being challenged are often reluctant to share their raw data. But an analysis of 49 studies appearing Wednesday in the journal PLoS One, by Dr. Wicherts, Dr. Bakker and Dylan Molenaar, found that the more reluctant that scientists were to share their data, the more likely that evidence contradicted their reported findings.

“We know the general tendency of humans to draw the conclusions they want to draw — there’s a different threshold,” said Joseph P. Simmons, a psychologist at the University of Pennsylvania’s Wharton School. “With findings we want to see, we ask, ‘Can I believe this?’ With those we don’t, we ask, ‘Must I believe this?’ ”

But reviewers working for psychology journals rarely take this into account in any rigorous way. Neither do they typically ask to see the original data. While many psychologists shade and spin, Dr. Stapel went ahead and drew any conclusion he wanted.

“We have the technology to share data and publish our initial hypotheses, and now’s the time,” Dr. Schooler said. “It would clean up the field’s act in a very big way.”

People Rationalize Situations They’re Stuck With, but Rebel When They Think There’s an out (Science Daily)

Uncategorized, , , , , ,

ScienceDaily (Nov. 1, 2011) — People who feel like they’re stuck with a rule or restriction are more likely to be content with it than people who think that the rule isn’t definite. The authors of a new study, which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, say this conclusion may help explain everything from unrequited love to the uprisings of the Arab Spring.

Psychological studies have found two contradictory results about how people respond to rules. Some research has found that, when there are new restrictions, you rationalize them; your brain comes up with a way to believe the restriction is a good idea. But other research has found that people react negatively against new restrictions, wanting the restricted thing more than ever.

Kristin Laurin of the University of Waterloo thought the difference might be absoluteness — how much the restriction is set in stone. “If it’s a restriction that I can’t really do anything about, then there’s really no point in hitting my head against the wall and trying to fight against it,” she says. “I’m better off if I just give up. But if there’s a chance I can beat it, then it makes sense for my brain to make me want the restricted thing even more, to motivate me to fight” Laurin wrote the new paper with Aaron Kay and Gavan Fitzsimons of Duke University.

In an experiment in the new study, participants read that lowering speed limits in cities would make people safer. Some read that government leaders had decided to reduce speed limits. Of those people, some were told that this legislation would definitely come into effect, and others read that it would probably happen, but that there was still a small chance government officials could vote it down.

People who thought the speed limit was definitely being lowered supported the change more than control subjects, but people who thought there was still a chance it wouldn’t happen supported it less than these control subjects. Laurin says this confirms what she suspected about absoluteness; if a restriction is definite, people find a way to live with it.

This could help explain how uprisings spread across the Arab world earlier this year. When people were living under dictatorships with power that appeared to be absolute, Laurin says, they may have been comfortable with it. But once Tunisia’s president fled, citizens of neighboring countries realized that their governments weren’t as absolute as they seemed — and they could have dropped whatever rationalizations they were using to make it possible to live under an authoritarian regime. Even more, the now non-absolute restriction their governments represented could have exacerbated their reaction, fueling their anger and motivating them to take action.

And how does this relate to unrequited love? It confirms people’s intuitive sense that leading someone can just make them fall for you more deeply, Laurin says. “If this person is telling me no, but I perceive that as not totally absolute, if I still think I have a shot, that’s just going to strengthen my desire and my feeling, that’s going to make me think I need to fight to win the person over,” she says. “If instead I believe no, I definitely don’t have a shot with this person, then I might rationalize it and decide that I don’t like them that much anyway.”

Mathematically Detecting Stock Market Bubbles Before They Burst (Science Daily)

Uncategorized, , , , , ,

ScienceDaily (Oct. 31, 2011) — From the dotcom bust in the late nineties to the housing crash in the run-up to the 2008 crisis, financial bubbles have been a topic of major concern. Identifying bubbles is important in order to prevent collapses that can severely impact nations and economies.

A paper published this month in the SIAM Journal on Financial Mathematics addresses just this issue. Opening fittingly with a quote from New York Federal Reserve President William Dudley emphasizing the importance of developing tools to identify and address bubbles in real time, authors Robert Jarrow, Younes Kchia, and Philip Protter propose a mathematical model to detect financial bubbles.

A financial bubble occurs when prices for assets, such as stocks, rise far above their actual value. Such an economic cycle is usually characterized by rapid expansion followed by a contraction, or sharp decline in prices.

“It has been hard not to notice that financial bubbles play an important role in our economy, and speculation as to whether a given risky asset is undergoing bubble pricing has approached the level of an armchair sport. But bubbles can have real and often negative consequences,” explains Protter, who has spent many years studying and analyzing financial markets.

“The ability to tell when an asset is or is not in a bubble could have important ramifications in the regulation of the capital reserves of banks as well as for individual investors and retirement funds holding assets for the long term. For banks, if their capital reserve holdings include large investments with unrealistic values due to bubbles, a shock to the bank could occur when the bubbles burst, potentially causing a run on the bank, as infamously happened with Lehman Brothers, and is currently happening with Dexia, a major European bank,” he goes on to explain, citing the significance of such inflated prices.

Using sophisticated mathematical methods, Protter and his co-authors answer the question of whether the price increase of a particular asset represents a bubble in real time. “[In this paper] we show that by using tick data and some statistical techniques, one is able to tell with a large degree of certainty, whether or not a given financial asset (or group of assets) is undergoing bubble pricing,” says Protter.

This question is answered by estimating an asset’s price volatility, which is stochastic or randomly determined. The authors define an asset’s price process in terms of a standard stochastic differential equation, which is driven by Brownian motion. Brownian motion, based on a natural process involving the erratic, random movement of small particles suspended in gas or liquid, has been widely used in mathematical finance. The concept is specifically used to model instances where previous change in the value of a variable is unrelated to past changes.

The key characteristic in determining a bubble is the volatility of an asset’s price, which, in the case of bubbles is very high. The authors estimate the volatility by applying state of the art estimators to real-time tick price data for a given stock. They then obtain the best possible extension of this data for large values using a technique called Reproducing Kernel Hilbert Spaces (RKHS), which is a widely used method for statistical learning.

“First, one uses tick price data to estimate the volatility of the asset in question for various levels of the asset’s price,” Protter explains. “Then, a special technique (RKHS with an optimization addition) is employed to extrapolate this estimated volatility function to large values for the asset’s price, where this information is not (and cannot be) available from tick data. Using this extrapolation, one can check the rate of increase of the volatility function as the asset price gets arbitrarily large. Whether or not there is a bubble depends on how fast this increase occurs (its asymptotic rate of increase).”

If it does not increase fast enough, there is no bubble within the model’s framework.

The authors test their methodology by applying the model to several stocks from the dot-com bubble of the nineties. They find fairly successful rates in their predictions, with higher accuracies in cases where market volatilities can be modeled more efficiently. This helps establish the strengths and weaknesses of the method.

The authors have also used the model to test more recent price increases to detect bubbles. “We have found, for example, that the IPO [initial public offering] of LinkedIn underwent bubble pricing at its debut, and that the recent rise in gold prices was not a bubble, according to our models,” Protter says.

It is encouraging to see that mathematical analysis can play a role in the diagnosis and detection of bubbles, which have significantly impacted economic upheavals in the past few decades.

Doctors Can Learn Empathy Through a Computer-Based Tutorial (Science Daily)

Uncategorized, , , ,

ScienceDaily (Oct. 31, 2011) — Cancer doctors want to offer a sympathetic ear, but sometimes miss the cues from patients. To help physicians better address their patients’ fears and worries, a Duke University researcher has developed a new interactive training tool.

The computer tutorial includes feedback on the doctors’ own audio recorded visits with patients, and provides an alternative to more expensive courses.

In a study appearing Nov. 1, 2011, in the Annals of Internal Medicine, the research team found that the course resulted in more empathic responses from oncologists, and patients reported greater trust in their doctors — a key component of care that enhances quality of life.

“Earlier studies have shown that oncologists respond to patient distress with empathy only about a quarter of the time,” said James A. Tulsky, MD, director of the Duke Center for Palliative Care and lead author of the study.

“Often, when patients bring up their worries, doctors change the subject or focus on the medical treatment, rather than the emotional concern. Unfortunately, this behavior sends the message, ‘This is not what we’re here to talk about.'”

Tulsky said cancer doctors have many reasons for avoiding emotionally fraught conversations. Some worry that the exchanges will cause rather than ease stress, or that they don’t have time to address non-medical concerns.

Neither is true, Tulsky said, noting his research shows that asking the right questions during patient visits can actually save time and enhance patient satisfaction.

“Oncologists are among the most devoted physicians — passionately committed to their patients. Unfortunately, their patients don’t always know this unless the doctors articulate their empathy explicitly,” Tulsky said. “It’s a skill set. It’s not that the doctors are uncaring, it’s just that communication needs to be taught and learned.”

The current gold standard for teaching empathy skills is a multiday course that involves short lectures and role-playing with actors hired to simulate clinical situations. Such courses are time-consuming and expensive, costing upwards of $3,000 per physician.

Tulsky’s team at Duke developed a computer program that models what happens in these courses. The doctors receive feedback on pre-recorded encounters, and are able to complete the intervention in their offices or homes in a little more than an hour, at a cost of about $100.

To test its effectiveness, Tulsky and colleagues enrolled 48 doctors at Duke, the Veterans Affairs Medical Center in Durham, NC, and the University of Pittsburgh Medical Center. The research team audio-recorded four to eight visits between the doctors and their patients with advanced cancer.

All the doctors then attended an hour-long lecture on communication skills. Half were randomly assigned to receive a CD-ROM tutorial, the other half received no other intervention.

The CD taught the doctors basic communication skills, including how to recognize and respond to opportunities in conversations when patients share a negative emotion, and how to share information about prognosis. Doctors also heard examples from their own clinic encounters, with feedback on how they could improve. They were asked to commit to making changes in their practice and then reminded of these prior to their next clinic visits.

Afterward, all the doctors were again recorded during patient visits, and the encounters were assessed by both patients and trained listeners who evaluated the conversations for how well the doctors responded to empathic statements.

Oncologists who had not taken the CD course made no improvement in the way they responded to patients when confronted with concerns or fears. Doctors in the trained group, however, responded empathically twice as often as those who received no training. In addition, they were better at eliciting patient concerns, using tactics to promote conversations rather than shut them down.

“Patient trust in physicians increased significantly,” Tulsky said, adding that patients report feeling better when they believe their doctors are on their side. “This is exciting, because it’s an easy, relatively inexpensive way to train physicians to respond to patients’ most basic needs.”

Although the CD course is not yet widely available, efforts are underway to develop it for broader distribution.

In addition to Tulsky, study authors include: Robert M. Arnold; Stewart C. Alexander; Maren K. Olsen; Amy S. Jeffreys; Keri L. Rodriguez; Celette Sugg Skinner; David Farrell; Amy P. Abernethy; and Kathryn I. Pollak.

Funding for the study came from the National Cancer Institute. Study authors reported no conflicts.
