On Monday, I participated in a panel discussion at the Brookings Institution on the Massachusetts v. EPA case. Other participants were Stuart Taylor; David Doniger of the Natural Resources Defense Council; David Sandalow of Brookings; science journalist Gregg Easterbrook; and environmental transaction lawyer Robert Reynolds (of Alston Bird). A transcript (uncorrected) of the discussion is available here. The discussion turned out to focus less on law, my particular expertise, than on environmental policy, but I found it worthwhile nonetheless. Note there is a discussion of Pat Michaels' climatologist amicus brief for the EPA at the very end of the transcript, during the Q&A period: the "speakers" in the brief exchange over that brief are David Doniger and me.
