Finally, an admission of error in the landmark report that won a Nobel Peace Price:
The UN’s top climate change body has issued an unprecedented apology over its flawed prediction that Himalayan glaciers were likely to disappear by 2035.
The Intergovernmental Panel on Climate Change (IPCC) said yesterday that the prediction in its landmark 2007 report was “poorly substantiated” and resulted from a lapse in standards. “In drafting the paragraph in question the clear and well-established standards of evidence, required by the IPCC procedures, were not applied properly,” the panel said. “The chair, vice-chair and co-chairs of the IPCC regret the poor application of IPCC procedures in this instance.”
The stunning admission is certain to embolden critics of the panel, already under fire over a separate scandal involving hacked e-mails last year.
The 2007 report, which won the panel the Nobel Peace Prize, said that the probability of Himalayan glaciers “disappearing by the year 2035 and perhaps sooner is very high”. It caused shock in Asia, where about two billion people depend on meltwater from Himalayan glaciers for their fresh water supplies during the dry seasons.
It emerged last week that the prediction was based not on a consensus among climate change experts but on a media interview with a single Indian glaciologist in 1999. That scientist, Syed Hasnain, has now told The Times that he never made such a specific forecast in his interview with the New Scientist magazine.
“I have not made any prediction on date as I am not an astrologer but I did say they were shrinking fast,” he said. “I have never written 2035 in any of my research papers or reports.” Professor Hasnain works for The Energy and Resources Institute (TERI) in Delhi, which is headed by Rajendra Pachauri, head of the climate change panel.
Models and predictions have a degree of uncertainty which will translate to errors and inconsistencies. What is troubling about this admission is that the process of validating data and supporting conclusions was systemically flawed. While it does not invalidate the entire report, this apology should be accompanied with a commitment to evaluate every claim made in the 2007 report.
Update: The vice-chairman of the UN's Intergovernmental Panel on Climate Change (IPCC), Jean-Pascal van Ypersele, states that the admission of error actually strengthens the credibility of the report:
"I don't see how one mistake in a 3,000-page report can damage the credibility of the overall report," he said.
"Some people will attempt to use it to damage the credibility of the IPCC; but if we can uncover it, and explain it and change it, it should strengthen the IPCC's credibility, showing that we are ready to learn from our mistakes," he further said.
