Claims of Himalayan Glacier Disaster Melt Away

Hugh Pickens writes "VOA News reports that leaders of the United Nations' Intergovernmental Panel on Climate Change have apologized for making a 'poorly substantiated' claim that Himalayan glaciers could disappear by 2035. Scientists who identified the mistake say the IPCC report relied on news accounts that appear to have misquoted a scientific paper — which estimated that the glaciers could disappear by 2350, not 2035. Jeffrey Kargel, an adjunct professor at the University of Arizona who helped expose the IPCC's errors, said the botched projections were extremely embarrassing and damaging. 'The damage was that IPCC had, or I think still has, such a stellar reputation that people view it as an authority — as indeed they should — and so they see a bullet that says Himalayan glaciers will disappear by 2035 and they take that as a fact.' Experts who follow climate science and policy say they believe the IPCC should re-examine how it vets information when compiling its reports. 'These errors could have been avoided had the norms of scientific publication including peer review and concentration upon peer-reviewed work, been respected,' write the researchers."

Four YEARS?

According to the NY Times article, a scientist (Georg Kaser) warned the working group in 2006 that the findings were erroneous. How did it take four years to bubble up?

I'd call that a pretty glacial response time. (rimshot)

Gpasp, there was a TYPO in a summary report, and the editing process didn't catch it.

A typo.

About as much a typo as your claim. If you RTFM (I know, asking a lot on /.), you will see that the UN Panel wrote the number in the report based on "a 2005 publication by the World Wildlife Fund. The WWF itself had picked it up from a 1999 magazine article based on a phone interview with an Indian scientist". In other words, the UN Panel read a random non-scientific report and used the erroneous prediction presented there. There is a massive failure here -- by the UN Panel when they relied on non-scientific sources for important predictions.

What are you talking about? The IPCC claimed the Himalayan glaciers would be gone by 2035. They based this on an article, based on an article, based on offhand speculation of a single scientist, who admits is was pure speculation with no supporting fact.

This wasn't a typo. It was damningly shoddy work on the part of the IPCC.

The paragraph starts, "Glaciers in the Himalayas are receding faster than in any other part of the world." Cogley and Michael Zemp of the World Glacier Monitoring System said Himalayan glaciers are melting at about the same rate as other glaciers.

From the AP report:

The mistakes were found not by skeptics like Michaels, but by a few of the scientists themselves, including one who is an IPCC co-author.

The report in question is the second of four issued by the IPCC in 2007 on global warming. This 838-page document had chapters on each continent. The errors were in a half-page section of the Asia chapter. The section got it wrong as to how fast the thousands of glaciers in the Himalayas are melting, scientists said.

"It is a very shoddily written section," said Graham Cogley, a professor of geography and glaciers at Trent University in Peterborough, Canada, who brought the error to everyone's attention. "It wasn't copy-edited properly."

Cogley, who wrote a letter about the problems to Science magazine that was published online Wednesday, cited these mistakes:

• It says that if the Earth continues to warm, the "likelihood of them disappearing by the 2035 and perhaps sooner is very high." Nowhere in peer-reviewed science literature is 2035 mentioned. However, there is a study from Russia that says glaciers could come close to disappearing by 2350. Probably the numbers in the date were transposed, Cogley said.
• The paragraph says: "Its total area will likely shrink from the present 500,000 to 100,000 square kilometers by the year 2035." Cogley said there are only 33,000 square kilometers of glaciers in the Himalayas.
• The entire paragraph is attributed to the World Wildlife Fund, when only one sentence came from the WWF, Cogley said. And further, the IPCC likes to brag that it is based on peer-reviewed science, not advocacy group reports. Cogley said the WWF cited the popular science press as its source.
• A table says that between 1845 and 1965, the Pindari Glacier shrank by 2,840 meters. Then comes a math mistake: It says that's a rate of 135.2 meters a year, when it really is only 23.5 meters a year.
