A positive step

Today's Supreme Court ruling on its opinion in Massachusetts v. EPA, ordering the federal government to look at regulating greenhouse gasses, is a positive step. While I harbor no illusions about this administrations willingness to make any substantial effort on global warming, they've lost one excuse for doing nothing.

WASHINGTON (AP) -- The Supreme Court ordered the federal government on Monday to take a fresh look at regulating carbon dioxide emissions from cars, a rebuke to Bush administration policy on global warming.

In a 5-4 decision, the court said the Clean Air Act gives the Environmental Protection Agency the authority to regulate the emissions of carbon dioxide and other greenhouse gases from cars.
