(plaintiffs claimed that defendants were at least partly the cause of "global warming" via the emission of greenhouse gases and had conspired to create a public nuisance by contributing to "global warming" and allegedly misleading the public about the consequences of "global warming"; trial court dismissed case on basis that plaintiffs lacked standing for failure to trace their injury directly to the defendants; on appeal, court affirmed; Clean Air Act (CAA) precludes public nuisance claims under public nuisance law in the realm of greenhouse gas regulation; court referenced U.S. Supreme Court opinion holding that federal common law addressing greenhouse gas emissions has been displaced by Congressional action; plaintiffs inadvertently admitted that "global warming" had been occurring for hundreds of years - before the advent of the industrial revolution and the internal combustion engine; court stated that plaintiffs could not "pick and choose amongst all the greenhouse gas emitters throughout history to hold liable for millions of dollars in damages").
