Indian climatologist disputes charges over Himalayan projection
London’s Sunday Mail reported that it had reached the author of a chapter in a purportedly authoritative 2007 climate-change assessment and learned that this scientist – Murari Lal – deliberately used unsubstantiated sources for conclusions about the rate of glacier melting in the Himalayas. Lal doesn’t dispute that mistakes were made – ones that likely exaggerated projections of glacier melting. But he does challenge the newspaper’s charge that those mistakes were politically motivated.

IPCC’s Himalayan glacier ‘mistake’ not an accident
A London newspaper reports today that the unsubstantiated Himalayan-glacier melt figures contained in a supposedly authoritative 2007 report on climate warming were used intentionally, despite the report’s lead author knowing there were no data to back them up.

Feds propose banning giant snakes
Today, the U.S. Fish & Wildlife Service announced plans to ban the importation and interstate transport of nine species of giant snakes. It’s a good idea, but a little like closing the barn door after the horse — or in this case, the pythons and anacondas — got loose.

BPA is regulated . . . sort of
Food and Drug Administration officials “say they are powerless to regulate BPA” because of a quirk in their rules, according to a story that ran Sunday in the Milwaukee Journal Sentinel. It comes from a reporter who has made an award-winning habit of documenting the politics that have helped make the hormone-mimicking bisphenol-A a chemical of choice for many manufacturers.

IPCC relied on unvetted Himalaya melt figure
British newspapers have uncovered what appears to be an embarrassing fact-checking omission by the Intergovernmental Panel on Climate Change, or IPCC. It regards the degree of glacial melting in the Himalayas — information that said parts of the area could be icefree a quarter century from now.
