The global political battle over climate change was also being fought at the US Supreme Court on Wednesday as judges bickered over the role of greenhouse gas emissions in global warming and disagreed on whether the Environmental Protection Agency had the power to refuse to regulate such emissions.
Hearing a case that could have a big impact on emission politics in the US Congress and beyond, judges listened to a Bush administration official defend the notion that the Environmental Protection Agency (EPA) should stay out of greenhouse gas regulation. They also heard from the state of Massachusetts, which insists that its coastline will be threatened unless the EPA steps in.
