People of State of California v. BP p.l.c.--Oakland and San Francisco brought claims against fossil-fuel producers re climate change; defendants removed the case to federal court and Oakland and San Francisco asked for a remind to state court. The federal court denied the request, stating among other things,"Plaintiffs’ claims for public nuisance, though pled as state-law claims, depend on a global complex of geophysical cause and effect involving all nations of the planet (and the oceans and atmosphere). It necessarily involves the relationships between the United States and all other nations. It demands to be governed by as universal a rule of apportioning responsibility as is available.”
