"U.S. EPA Administrator Lisa Jackson today defended the science underpinning pending climate regulations despite Senate Republicans' claims that global warming data has been thrown into doubt.
'The science behind climate change is settled, and human activity is responsible for global warming,' Jackson told the Senate Environment and Public Works Committee. 'That conclusion is not a partisan one.'
Jackson's comments came as the Senate panel scrutinized President Obama's $10 billion budget request for EPA. The administration's fiscal 2011 proposal would cut the agency's total funding by about $300 million from 2010 levels while allotting $56 million -- including $43 million in new funding -- for regulatory programs to curb greenhouse gas emissions."
