The Center for Public Integrity, a non-profit investigative journalism organization, has posted a clear and useful piece, "Climate Facts -- and Fancy," on what, precisely, the EPA has proposed to do about greenhouse gas regulation. For example, despite talk to the contrary, regulating cow flatulence is not on the list. Really.

It's a good time to know the details. It came to a head this week at the nation's Capitol as the House passed a bill to restrict the EPA's authority around greenhouse gas emissions, and the Senate rejected it. But, as the report points out:

As frequently happens during such showdowns, claims and counter-claims on both sides flew fast and furious — among them a few wily distortions and utter fictions you're likely to hear again because the dueling combatants are just getting warmed up. While the votes were largely symbolic and have no chance of becoming law, the debate allowed partisans on both sides to stake out territory they'll revisit in the run-up to the 2012 election.
