Major reform for climate body (Nature)

Intergovernmental panel aims to become more responsive.

IPCC chairman Rajendra Pachauri faced calls to quit after errors were
found in a key report.

After months of soul-searching, the Intergovernmental Panel on Climate
Change (IPCC) has agreed on reforms intended to restore confidence in
its integrity and its assessments of climate science.

Created as a United Nations body in 1988 to analyse the latest
knowledge about Earth’s changing climate, it has worked with thousands
of scientists and shared the Nobel Peace Prize in 2007. But its
reputation crumbled when its leadership failed to respond effectively
to mistakes — including a notorious error about the rate of Himalayan
glacier melting — that had slipped into its most recent assessment
report (see Nature 463, 276–277; 2010).

That discovery coincided with the furore over leaked e-mails from the
University of East Anglia’s Climatic Research Unit in Norwich, UK (see
Nature 462, 397; 2009). Some e-mails seemed to show that leading
climate scientists, who had contributed key findings to previous IPCC
reports, had tried to stifle critics. This put the panel — especially
its chairman, Rajendra Pachauri — under intense pressure. The
InterAcademy Council, a consortium of national science academies, was
commissioned to review the structure and procedures of the IPCC and to
suggest improvements to its operations (see Nature 467, 14; 2010).

The council identified the lack of an executive body as a key factor
in the IPCC’s failure to respond to the crisis. It also urged the
panel to improve the transparency of its assessments and to make its
communication and outreach activities more professional. The IPCC
adopted several minor changes at a meeting last October (see Nature
467, 891–892; 2010).

More substantial reforms were signed off last week in Abu Dhabi at a
meeting of delegates from IPCC member states. An executive committee
will be created to oversee the body’s daily operations and to act on
issues that cannot wait for full plenary meetings. The 13-strong
committee will be led by the chairman, and includes the vice-chairs
and co-chairs of its working groups and technical support units.

A new conflict-of-interest policy will require all IPCC officials and
authors to disclose financial and other interests relevant to their
work (Pachauri had been harshly criticized in 2009 for alleged
conflicts of interest.) The meeting also adopted a detailed protocol
for addressing errors in existing and future IPCC reports, along with
guidelines to ensure that descriptions of scientific uncertainties
remain consistent across reports. “This is a heartening and
encouraging outcome of the review we started one year ago,” Pachauri
told Nature. “It will strengthen the IPCC and help restore public
trust in the climate sciences.”

The first major test of these changes will be towards the end of this
year, with the release of a report assessing whether climate change is
increasing the likelihood of extreme weather events. Despite much
speculation, there is scant scientific evidence for such a link —
particularly between climate warming, storm frequency and economic
losses — and the report is expected to spark renewed controversy.
“It’ll be interesting to see how the IPCC will handle this hot potato
where stakes are high but solid peer-reviewed results are few,” says
Silke Beck, a policy expert at the Helmholtz Centre for Environmental
Research in Leipzig, Germany.

The IPCC overhaul is not yet complete. Delegates postponed a decision
about the exact terms of office of the group’s chairman and head of
the secretariat. Critics say that these terms should be strictly
limited to the time it takes to produce a single assessment report,
about six or seven years. With no clear decision on that issue,
Pachauri could theoretically remain in office beyond 2014, when the
next full report is due for release.

But the Indian economist says he has not considered staying on that
long. “My job is to successfully complete the next assessment,” he
says. “That’s what I’m solely focused on.”

Anthropology and Climate Science Controversies

Brad Walters (Mount Allison U.)

Enormous research effort has been invested in the study of climate change. Many scientists reveled in the acclaim that followed last-year’s awarding of the Nobel Peace Prize to the Inter-governmental Panel on Climate Change (IPCC). This year, some of these same scientists have faced an onslaught of criticism as a result of a few mistakes found in published reports of the IPCC and leaked emails from an eminent, UK-based science group that revealed an all-too-human side of the scientific endeavor (so-called “climate-gate”).

The editors of the pre-eminent science journal Nature commented that these supposedly explosive revelations would be laughable were it not for their policy consequences. Like many, they recognize that the real scandal has little to do with climate change science, but everything to do with its political ramifications.

The scientific consensus on climate change is rock solid on the most critical issues: greenhouse gas emissions from human activity are now warming the earth’s climate at a rate that is extremely rapid by historical and recent geological standards and this poses increasingly serious risks our well being (Union of Concerned Scientists, March 2010, “U.S. scientists and economists’ call for swift and deep cuts in greenhouse gas emissions,” http://www.ucsusa.org). The evidence for this general conclusion is so broad, diverse and compelling that virtually no reputable scientist doubts it.

Yet, large swaths of the American public and many opinion leaders continue to doubt the reality of climate change. A major reason for this is that the controversies over the credibility of climate science are to a large degree intentionally contrived by people and organizations with vested interests in the economic status-quo and fear of government regulation, particularly members of the oil, gas and coal industries. What we are witnessing today, according to authors James Hoggan and Richard Littlemore (Climate Cover-Up: The Crusade to Deny Global Warming) and George Monbiot (Heat), is a similar but much more ambitious replay of the tobacco industries’ campaign in the 1980s and 1990s to sew doubt about the scientific consensus on the health risks of smoking. These climate deniers understand what many social scientists do: where there is uncertainty in the minds of the electorate, the political cost of inaction falls while the cost of decisive action rises.

These climate controversies raise intriguing questions for anthropologists who may have interests in issues of public knowledge formation, risk perception, and the application of expert and non-expert knowledge in policy making. But, what motivated me to write this column is a different question: do many anthropologists also not trust the credibility of the scientific “experts” on the matter of climate change?

I came to this question as a result of recent exchanges on the Environmental Anthropology (E-Anth) List-serve that revealed a far less solid consensus on the matter than is found within the mainstream climate science community, which is dominated by natural scientists. Specifically, postings by some list members revealed a surprising lack of trust in the credibility of scientific bodies like the IPCC and the National Academy of Sciences. Even more troubling was their referencing of scientifically un-credible sources—climate skeptics’ blogs, for example—as the basis for their opinions on the status of climate science.

Anthropologists are not alone in having within their ranks credentialed scientists who espouse views on climate change that are totally unsupportable in any reasonable scientific sense. But is it possible that anthropologists are particularly vulnerable to this kind of anti-scientific way of thinking about the issue? Has the disciplines’ deep emersion in subjects like the social construction of knowledge produced social scientists with so little trust and respect for the work of natural scientists that they won’t (or can’t!) distinguish between peer-reviewed research and politically-motivated blog postings?

There is a point reached—and we are now well passed it in climate science—where theoretical arguments and empirical evidence are so overwhelmingly compelling that positions contrary to the scientific consensus are simply untenable. Perhaps it is time for the AAA to step-up as a body and officially state their position on this most critical of issues.
