The Supreme Court takes a global warming case....

... with Justice Sonia Sotomayor recusing herself. American Electric Power Co. v. Connecticut involves the use of a common law theory of nuisance:

[Five companies] that were claimed to be the largest sources of greenhouse gases — four electric power companies and the Tennessee Valley Authority — were sued by eight states, New York City, and three land conservation groups...

Calling the potential impact of the nuisance theory “staggering,” the companies’ petition said that virtually every entity and industry in the world can be found to be partly responsible for some emissions of carbon dioxide, so they are potentially liable to be sued in climate changed nuisance lawsuits.

When it comes to carbon dioxide, we're all a damned nuisance.
