NOAA chief backs UN climate panel


The IPCC’s credibility is important because its work helps form the basis for numerous climate change policies and proposals. It is among the major sources the Environmental Protection Agency relied on in crafting its late 2009 “endangerment finding” that greenhouse gases threaten human health and welfare. The EPA finding is a precursor to planned emissions regulations.

Climate skeptics and opponents of climate legislation have pounced on the IPCC glacier error and other alleged flaws in the vast 2007 report. Sen. John Barrasso (R-Wyo.), a leading Senate opponent of climate change legislation, this month called for the resignation of IPCC Chairman Rajendra Pachauri.
