The 9th Circuit Court of Appeals will meet Tuesday in Portland to hear arguments in the constitutional challenge to climate change policy brought by 21 young people. The plaintiffs in Juliana v. United States were assembled by an Oregon lawyer and the lead plaintiff is a University of Oregon student. They argue that because government policy is worsening climate change, it is violating their constitutional rights to life, liberty, and property, and failing to protect vital public resources. We’ll hear what they’re thinking about the day before the judges meet to consider the case.
