On May 14, the U.S. Court of Appeals for the Fifth Circuit released its decision in a case involving Hurricane Katrina and global warming, upholding a previous decision to dismiss the lawsuit. Residents of Mississippi on the Gulf Coast filed a suit against energy companies, saying their emissions contributed to climate change which worsened the effects of Hurricane Katrina. The U.S. District Court for the Southern District of Mississippi dismissed the case because the plaintiffs had already sued the companies in 2005; the appellate court agreed with the decision to dismiss the case.
