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.

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.
