Kelsey Juliana, of Eugene, Ore., a lead plaintiff who is part of a lawsuit by a group of young people who say U.S. energy policies are causing climate change and hurting their future, greets supporters outside a federal courthouse, June 4, 2019, in Portland, Ore. A federal judge ruled on Thursday, June 1, 2023, that a lawsuit brought by young Oregon-based climate activists can proceed to trial years after they first filed the lawsuit in an attempt to hold the nation’s leadership accountable for its role in climate change.
