Gardere Wynn has published an interesting new "alert" on a recent Texas trial court ruling said to have - in dicta - embraced the idea of applying the public trust doctrine to air as well as to water. The alert provides a nice update for anyone lacking the time to keep track of what's going on in the global warming cases.
Here is Walter Olson's recent post linking to articles and underlying documents regarding California's voluntary dismissal of its appeal in its global warming lawsuit against car makers. Here, Jenner & Block provides some older commentary on other rulings in the area. For pro plaintiff coverage, see the warminglaw blog that is here and an old post here includes a link to the district court's opinion.
