Climate-gate, scepticism, and Pachauri’s potboiler

Cross-posted from Daniel Cressey on The Great Beyond

Just in case you think that the IPCC/climate-gate story has petered out in the last few days…

Phil Jones, the University of East Anglia scientist whose stolen emails caused the worldwide ‘climate-gate’ kerfuffle, has told The Sunday Times he contemplated killing himself.

“I did think about it, yes. About suicide,” he says. “I thought about it several times, but I think I’ve got past that stage now.”

Indian Prime Minister backs IPCC

Quirin Schiermeier

Indian Premier Manmohan Singh has backed the work of the Intergovernmental Panel on Climate Change (IPCC) and its chairman, Rajendra Pachauri, who has come under fire for his dealing with a recently discovered error and a number of other alleged inaccuracies in the last IPCC report.

The IPCC had mistakenly stated in its 2007 report that all Himalayan glaciers are likely to melt away by 2035 as a result of global warming. The error, and allegations of conflict of interest against Pachauri, who also acts as director of The Energy Research Institute (TERI) in Delhi, have resulted in calls for Pachauri to resign as chairman of the IPCC.

Addressing a TERI-hosted meeting in Delhi on sustainable development Singh acknowledged that "some aspects of science reflected in the work of the IPCC have faced criticism".

But he said that "India has full confidence in the IPCC process and its leadership and will support it in every way."

Pachauri conceded last month that the IPCC's Himalayan estimates were wrong, but asserts that he was not personally responsible for the error.

Quotes of the day

Cross-posted from Mark Peplow on The Great Beyond

“Sanjay put his arms around her and kissed her, first with quick caresses and then the kisses becoming longer and more passionate.”
UN climate change supreme Rajendra Pachauri gets physical in a line from his novel, Return to Almora, published last month. The Telegraph has some more – ahem – graphic extracts.

“We need to work differently, making more data available and making our assumptions clear. Everything needs to be more and more open and we will be striving to do that in the future.”
Phil Jones, former director of the Climatic Research Unit at the University of East Anglia, UK, on the need for a change in attitude amongst climate scientists. (The Times)

The road from Copenhagen

Olive Heffernan

The latest issue of Nature Reports Climate Change, online today, takes a look at what is next for climate policy post-Copenhagen. I put together a round-up of responses from several experts on what they consider to be the most important milestones on the road from Copenhagen. I was curious as to where that road should lead to: Mexico in November, South Africa in 2011, or some destination outside of the UN calendar of scheduled conferences? Do we need a different route altogether, considering the failure of the UN to deliver an agreement in Copenhagen that everyone, well, agreed on.

But first of all, an admonition: I did actually invite responses from experts outside of the ‘male, white, middle-aged and living in the developed world’ category, but sadly none of these responded within our timeframe for the piece. Despite the relatively uniform appearance of our respondents, their views are, however, quite diverse on how we should move forward on tackling climate change from a legislative standpoint.

The full article is available here [free access], but I’ll flag up some of the highlights here:

Mike Hulme of the University of East Anglia says we need a more radical approach to climate policy, one in which different forcing agents are treated in different ways. “One could have two separate treaties: one controlling short-lived agents such as black soot and methane, and one concerned solely with carbon dioxide”, says Hulme. He also said to me that uncoupling powerful short-lived agents from carbon dioxide would also have the distinct advantage of dissociating part of the problem from the political issue of energy. Presumably, in that way, we would solve part of the problem without getting embroiled in all of the politics of vested interests.

Aside from that, Hulme says he thinks that we need near-term targets that are pragmatic and technology-based, rather than aspirational targets driven by IPCC science. “It’s better to be pragmatic than to be overly aspirational; surely the lessons of the 12 years since Kyoto tell us that?”, asks Hulme.

Roger Pielke Jr of the University of Colorado in Boulder agrees on the need to step away from aspirational targets and timetables for emissions reductions. “It is often said that the definition of insanity is doing the same thing and expecting different results. [Yet] many in the climate debate seem ready to put the Copenhagen experience out of their minds and gear up for doing it all over again in Mexico City”, says Pielke Jr.

Jonathan Lash, president of the World Resources Institute in Washington DC, is far more optimistic about the UN process and says that a legally binding climate treaty, hopefully delivered in Mexico, is still the ultimate goal. Lash says there will be nearer-tern milestones to watch out for on the road to Mexico, however, including China’s twelfth Five-Year Plan, due out this spring. Also if the US passes domestic climate legislation, this will be an important landmark on the road to international legislation, says Lash.

John Schellnhuber, climate advisor to the German government and director of the Potsdam Institute for Climate Research, Germany, says we should be looking to the UN meeting in Bonn this summer as a crucial test-bed for avenues beyond the Copenhagen quagmire. But ultimately, says Schellnhuber, what’s needed for the UN process to work – and to forge a global deal that will be tolerated by everyone - is co-operation between the US and China.

IPCC: in need of a rethink?

Olive Heffernan

Today on Nature.com, my colleague Quirin Schiermeier reports on the allegations that have, of late, been plaguing the UN body that assesses the science of climate change. Aside from Glaciergate and other claims of inaccuracy in reporting the science, now Rajendra Pachauri, chair of the Intergovernmental Panel on Climate Change, is under pressure to resign because the institute he directs, the Energy and Resources Institute in New Delhi, has ties with companies that could benefit from climate policies, writes Schiermeier.

In response, many climatologists have been considering how the body might reconsider its rules and procedures in an effort to reduce errors in the final product and create policies on potential conflicts of interest.

The next assessment report, known as AR5 and due out in 2013, will follow the same basic outline as its last one, with three working groups to tackle three areas of interest: the physical science of climate change, the impacts such change is likely to have and how these might be mitigated. There are two review editors for each chapter and the whole thing will be checked before publication, first by expert reviewers and then by governments.

Those closely involved in the process insist that it works well, but others say there is room for improvement. Kevin Trenberth of the National Center for Atmospheric Research in Boulder, Colorado, a lead author of the 2007 report, told Schiermeier that critics have grossly underestimated the rigour of the IPCC review process. But, he says that the reports from the three working groups could be better coordinated.

"IPCC reports are written by humans," says Jürgen Willebrand, an oceanographer at the Leibniz Institute of Marine Sciences in Kiel, Germany, and a coordinating lead author of the 2007 report. As such, some errors will creep in, he says. "I have no doubt that similar errors could be found in earlier IPCC reports, but nobody has bothered to look in detail because at the time of these reports the IPCC was less visible to society, politics and media." But he says the IPCC should have a more formal process for ensuring each flagged error is dealt with promptly.

Willebrand also calls for the IPCC to develop a policy on potential conflicts of interest. Schiermeier says any changes to the structure or leadership of the panel would need to be approved in its next plenary session, which will take place in October in Busan, South Korea.

Constructive communication

Olive Heffernan

The past two months have been an unnerving time for the international climate community. Once seen as one of the most esteemed scientific organizations in the world, the Intergovernmental Panel on Climate Change has, of late, suffered some serious blows to its reputation.

The first of these — dubbed 'Climategate' — saw thousands of emails obtained illegally from the University of East Anglia in the United Kingdom and posted on the Internet. Carefully timed ahead of international climate policy negotiations, the emails showed apparent attempts by a handful of IPCC climatologists to withhold data from climate deniers and to exclude contentious information from the panel's report. Unsurprisingly, this cast doubt on the credibility of the UN body.

Now, the process by which the IPCC assesses climate science has again been called into question. Over the past two weeks, the panel has admitted that a key statistic quoted in its 2007 report — that Himalayan glaciers could disappear by 2035 — was in error, and its source of dubious origin. Hard on the heels of 'Glaciergate' are fresh claims that the same report oversold the link between increasing natural disasters and human-induced warming.

None of these unfortunate events calls into question the evidence that warming is unequivocal and that human activity is the primary cause. But they undoubtedly create confusion among the public and, in this regard, their timing could not be worse. The UN negotiations in December failed to deliver an agreement that would prevent dangerous climate change, and the world now lacks a unified vision of the way forward for climate policy. The passage of US domestic legislation also hangs in the balance.

To some extent, the end of the IPCC's exaltation was inevitable. Any organization or individual that is placed on a pedestal will eventually come a cropper. That hard lesson is being learnt as much by the Nobel prize-winning US President as by the Nobel prize-winning IPCC.
