A judge in Washington DC has blocked oil and gas drilling on almost 500 square miles in Wyoming. He says the US must consider climate change impacts more broadly as they lease huge sections of public land for energy exploration. The order reflects the latest in a string of court rulings over the past decade faulting the governments lack of consideration of emission when they issue energy leases. This time, U.S. District Judge Rudolph Contreras went further saying the US must consider the impacts of emissions nationwide. The ruling is linked to a lawsuit challenging leases issued in Wyoming, Utah and Colorado in 2015 and 2016.
