State of Connecticut, et al. v. American Electric Power Co., Inc., et al., 582 F.3d 309 (2nd Cir. 2009)

(in reversal of trial court, court holds that plaintiff states may bring common law public nuisance claim against electric utilities in attempt to force reductions in carbon dioxide emissions to combat supposed "global warming"; emissions need not be "poisonous" or "noxious" in nature or capable of producing immediate harm to be challenged in court; issue not merely a political question).
