Scientists misread data on global warming controversy

"If you can keep your head when all about you are losing theirs and blaming it on you," then, with apologies to Kipling, you might not be a climate scientist.
Well-publicized troubles have mounted for those forecasting global warming. First, there was last year's release of
hacked e-mails from the United Kingdom's University of East Anglia, showing some climate scientists really dislike their critics (investigations are still ongoing). Then there was the recent discovery of a botched prediction that all Himalayan glaciers would disappear by 2035 in one of the Nobel-Prize-winning 2007 Intergovernmental Panel on Climate Change (IPCC) reports. Instead, the glaciers are only shrinking about as much as glaciers everywhere, twice as fast as they did 40 years ago, suggest results from NASA's GRACE gravity-measuring orbiter.
The recent controversies "have really shaken the confidence of the public in the conduct of science," according to atmospheric scientist
Ralph Cicerone, head of the U.S. National Academy of Sciences. Cicerone was speaking at the American Association for the Advancement of Science meeting last month on a panel calling for more communication and release of data to rebuild lost trust for scientists. IPCC chiefs have made similar calls in the handling of their reports.
Scientists see
reason for worry in polls like one released in December by Fox News that found 23% of respondents saw global warming as "not a problem," up from 12% in 2005. Also at the AAAS meeting, Yale, American University and George Mason University released a survey of 978 people challenging the notion that people 18 to 35 were any more engaged than their elders on climate change. Statistically, 44% in that age range — matching the national average — found global warming as either "not too important" or "not at all important," even though they grew up in an era when climate scientists had found it very likely that temperatures had increased over the last century due to fossil fuel
