In a sign of the tough road ahead for the Biden administration’s ambitious energy policy, a group representing fossil fuel producers sued the administration Wednesday. The Western Energy Alliance alleges that the pause on oil and gas leases on federal land and waters exceeds presidential authority. The suit comes as the administration rolled out a series of executive orders to address climate change.

U.S. climate envoy John Kerry said, “The stakes on climate change just simply couldn’t be any higher than they are right now. It is existential.”
