A detail of the West Facade of the U.S. Supreme Court is seen in Washington, Monday, March 7, 2011. The court is taking up a climate change case for the second time in four years. On Tuesday, April 19, the court will hear arguments in the case American Electric Power Co. v. Connecticut, 10-174. The Obama administration is siding with American Electric Power Co. and three other companies in urging the high court to throw out the lawsuit on grounds the Environmental Protection Agency, not a federal court, is the proper authority to make rules about climate change.
