HELENA, Mont. (AP) — Young people challenging Montana officials over inaction on climate change are expected back in state court on Tuesday in a first-of-a kind trial of a lawsuit that environmentalists hope will spur changes in the fossil fuel-friendly state.

State officials have sought to downplay Montana's contributions to global warming as the trial that opened Monday is being closely watched for possible legal precedents even though the scope of the lawsuit has been narrowed in earlier rulings.
