FILE - Lead plaintiff Rikki Held testifies during a hearing in the climate change lawsuit, Held vs. Montana, at the Lewis and Clark County Courthouse, June 12, 2023, in Helena, Mont. A Montana judge in August 2023 sided with young environmental activists who said state agencies were violating their constitutional right to a clean and healthful environment by permitting fossil fuel development without considering its effect on the climate. The state's effort to overturn the ruling is now before the Montana Supreme Court. (Thom Bridge/Independent Record via AP, File)
