 The state appealed the decision, saying Montana is not solely responsible for climate change, so the state cannot fix it. Montana's case was the first youth-led climate lawsuit to go to trial last June. This hearing comes on the heels of similar climate litigation led by the national law firm Our Children's Trust. A group of young people in Hawaii recently settled with the state's transportation department, and cases are pending in Alaska and Utah. For NPR News, I'm Ellis Julin in Missoula.
