Monday's Supreme Court decision to repudiate the Bush administration's denial of the government's authority to regulate greenhouse gas emissions is a great step forward in battling climate change. However, at this point it's a more of a symbolic victory since the EPA could stall for years (or at least until the next administration comes in). In an ABC News on-line article, the Sierra Club's Josh Dorner said, "It puts a process into motion that essentially compels the EPA to at some point issue regulations on carbon dioxide. I think, obviously, that process will be a slow one and we might see some action in Congress before that process comes to full fruition."
The only skeptics quoted in this article were the four dissenting justices.
The Washington Post notes another environmental case, Environmental Defense et al. v. Duke Energy Corp. et al ., in which the court unanimously supported a Clinton-era initiative to force old coal-powered power plants to install pollution-control equipment.
The L.A. Times called the high court's ruling a victory for California.
The NYT called the ruling a "strong rebuke" to the Bush administration.
