A three-judge panel of the Ninth U.S. Circuit Court of Appeals heard oral arguments in San Francisco...in the case of Kivalina v. ExxonMobil. Kivalina filed suit against Exxon and 23 other oil companies, coal companies and power companies, alleging that they are responsible for global warming, which is destroying sea ice, which means that Kivalina must be moved at a cost of anywhere from $95 million to $400 million...Kivalina claims that the companies have damaged the village by their actions and some of them have engaged in a conspiracy to spread falsehoods about climate change. The defendants in the case say that the attempt to blame selected companies for "contributing" to the "alleged nuisance" of global warming is without merit.
