U.N. climate chiefs apologize for glacier error
By Matthew Knight, for CNN
STORY HIGHLIGHTS
* The IPCC has apologized for publishing "poorly substantiated estimates" about Himalayan glacier melt
* Information in 2007 IPCC report was sourced to speculative claim made in a UK science journal
* Climate scientists remain convinced of global warming trend
* Glaciers "best proof that climate change is happening

(CNN) -- The U.N.'s leading panel on climate change has apologized for misleading data published in a 2007 report that warned Himalayan glaciers could melt by 2035.
In a statement released, Wednesday, the Intergovernmental Panel on Climate Change (IPCC) said estimates relating to the rate of recession of the Himalayan glaciers in its Fourth Assessment Report were "poorly substantiated" adding that "well-established standards of evidence were not applied properly."
Despite the admission, the IPCC reiterated its concern about the dangers melting glaciers present in a region that is home to more than one-sixth of the world's population.
"Widespread mass losses from glaciers and reductions in snow cover over recent decades are projected to accelerate throughout the 21st century, reducing water availability, hydropower potential, and changing seasonality of flows in regions supplied by meltwater from major mountain ranges (e.g. Hindu-Kush, Himalaya, Andes)..."
"The chair, vice-chairs, and co-chairs of the IPCC," the statement continued, "regrets the poor application of IPCC procedures..."
The apology follows a growing storm of controversy which initially forced the IPCC to concede that data relating to the Himalayan glacier melt included in the 2007 report was not backed up by sufficient scientific data.
Speaking at the World Future Energy Summit in Abu Dhabi Wednesday, the IPCC chairman, Rajendra Pachauri admitted errors had been made but said it was not an excuse question the legitimacy of all global warming science.
"Theoretically, let's say we slipped up on one number, I don't think it takes anything away from the overwhelming scientific evidence of what's happening with the climate of this earth," he said, according to Agence France-Presse.
The controversy centers on a paragraph in Chapter 10 of the 2007 report which states: "Glaciers in the Himalaya are receding faster than in any other part of the world, and if the present rate continues, the likelihood of them disappearing by the year 2035 and perhaps sooner is very high if the Earth keeps warming at the current rate. Its total area will likely shrink from the present 500,000 to 100,000 square kilometers by the year 2035. "
But is has recently emerged that the IPCC statement on Himalayan glaciers, which was based on information from a 2005 report by the World Wildlife Fund, was in turn gleaned from a article that appeared in the popular UK science journal, The New Scientist in June 1999.
In the article, "Flooded Out," Indian glaciologist Syed Hasnain speculates that that the Himalayan glaciers could vanish within 40 years as a result of global warming.
A glacier expert interviewed by CNN explained that the data published was flawed.
Michael Zemp from the World Glacier Monitoring Service said: "There are simply no observations available to make these sorts of statements."
Zemp says that the figures quoted in the report are not possible because 500,000 square kilometers is estimated to be the total surface area of all mountain glaciers worldwide.
"The other thing is that the report says the glaciers are receding faster than anywhere else in the world. We simply do not have the glacier change measurements. The Himalayas are among those regions with the fewest available data," Zemp said.
In defense of the IPCC, Zemp says "you can take any report and find a mistake in it but its up to the next IPCC report to correct it."
Zemp also believes that the errors shouldn't shake people's belief in climate science.
"Glaciers are the best proof that climate change is happening. This is happening on a global scale. They can translate very small changes in the climate into a visible signal," he said.

In the interest of fairness, here is a letter from a friend:
Hi Rabbi Gottlieb,
After reading your "Climate Science" post on your blog, I thought I'd share the following.
Although I found myself not wanting to see a video that took the climate scientists viewpoint of the hacked emails story, I finally couldn't resist. I must say that it shook my resolve a bit:
http://www.youtube.com/watch?v=7nnVQ2fROOg
The fellow in the video makes the best case so far I've seen (although not without a couple of problems) that the CRU emails scandal isn't really as scandalous as many so-called deniers make it out to be. Be that as it may, I do NOT believe that the "science has been settled."
If I may, I'd like to share a quote that I really think you'll like. It's from Eisenhower:
http://www.americanrhetoric.com/speeches/dwightdeisenhowerfarewell.html
Today, the solitary inventor, tinkering in his shop, has been overshadowed by task forces of scientists in laboratories and testing fields. In the same fashion, the free university, historically the fountainhead of free ideas and scientific discovery, has experienced a revolution in the conduct of research. Partly because of the huge costs involved, a government contract becomes virtually a substitute for intellectual curiosity. For every old blackboard there are now hundreds of new electronic computers. The prospect of domination of the nation's scholars by Federal employment, project allocations, and the power of money is ever present -- and is gravely to be regarded.
Yet, in holding scientific research and discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite.
