Whoa! Stopped home for lunch today, and what do I find, but that the Supreme Court has ruled (5-4) against the US EPA's refusal to regulate greenhouse gases. Grist has a quick overview here, and you can read the whole opinion, including two dissents from Chief Justice Roberts and Justice Scalia, here.
This is big, but I think it can go in two general ways. First, the EPA puts up some perfunctory regulations, whose primary result is a lessening in urgency to act. Second, this could give moderate Republicans and Democrats the impetus and/or cover to support stronger regulations formulated by Congress, such as Henry Waxman's Safe Climate Act.
I was going to say that it's wait-and-see time, but that's not really true. I think this ups the case for action. April is chock full of opportunities to get involved--to rally, to discuss, to make commitments. I'll be posting about upcoming events throughout the month--consider coming out to show your support or find out what you can do.
