First it was Climategate in which leaked emails revealed major scientific corruption at one of the world’s leading global warming research centers.  Then, the U.N. was forced to recant on its claims about the melting of the Himalayas.  And now?  Well how about the U.N.’s main science body, the IPCC, being forced to admit that an alarming 2007 report regarding 40% of the Amazon being in danger from climate change was based on unsubstantiated claims by environmental activists.  The IPCC had claimed even a slight change in rainfall could turn swaths of rainforest into savannah grassland, but this was based on an earlier report that wasn’t even about global warming but about drier forests being more prone to fire.  Talk about going from bad to worse.
