Young environmentalists won a landmark climate change ruling in Montana. Will it change anything?

Young environmental activists prevailed in a closely watched Montana lawsuit that said state officials weren't doing enough to protect them from climate change. Legal observers called it a landmark victory for the 16 plaintiffs: It marks the first time a court in the U.S. has declared that a government has a constitutional duty to protect people from climate change. State District Judge District Judge Kathy Seeley said officials violated Montana's highly protective constitution by refusing to consider the impacts of greenhouse gas emissions when they've approved coal mines, oil drilling and new power plants.
