 The Montana Supreme Court heard oral arguments this week in the state's appeal of a landmark climate ruling. Montana Public Radio's Alice Julin reports. The state is asking the Montana Supreme Court to overturn a district court ruling that found Montana's fossil fuel-friendly policies have violated the 16 youth plaintiffs' constitutional right to a clean and healthful environment. Attorneys for the state said the court can't address the harms to young people because climate change is a global issue.
