 The Montana Supreme Court heard oral arguments this week in the state's appeal of the 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.
