From the AP:
Officials of 18 states are taking the EPA back to court to try to force it to comply with a Supreme Court ruling that rebuked the Bush administration for inaction on global warming.
In a petition prepared for filing Wednesday, the plaintiffs said last April's 5-4 ruling required the Environmental Protection Agency to decide whether to regulate greenhouse gas emissions, including carbon dioxide, from motor vehicles.
The EPA has instead done nothing, they said.
"The EPA's failure to act in the face of these incontestable dangers is a shameful dereliction of duty," Massachusetts Attorney General Martha Coakley said.
The petition asks the U.S. Court of Appeals for the D.C. Circuit to require the EPA to act within 60 days.
