According to the ever reliable NYT, The E.P.A.’s administrator, Lisa P. Jackson, said Monday

that the finding was driven by the weight of scientific evidence that the planet was warming and that human activity was largely responsible.

“There have and continue to be debates about how and how quickly climate change will happen if we fail to act,” Ms. Jackson said at a news conference at the E.P.A.’s headquarters. “But the overwhelming amounts of scientific study show that the threat is real.”

The “overwhelming amounts of scientific study” was created by a small cabal of climatologists who faked their data and used computer models that were complete garbage. Lisa P. Jackson is a typical Obama fan, living in a fantasy world. The world would be much better off if she stopped emitting CO2, at least in public.
