Supreme Court to make big call on whether fossil fuels should be held responsible for climate change

The U.S. Supreme Court will hear Suncor v. Boulder, a case where Boulder, Colorado, sued ExxonMobil and Suncor Energy for climate change-related damages. The companies argue the suits are an attempt to regulate emissions. The court will decide if federal law preempts the claims and if the Constitution bars such suits. According to the plaintiffs, they have suffered hundreds of millions in losses from climate-related events.
