Climate Change Chronicles

A photo of Levi Draheim on a sunny day standing in front of a beach. His green shirt says "Climate Change is Real"

Twenty-one young people — including Levi Draheim, 11, from Satellite Beach, Fla. — have sued the U.S. government for actions that they say contributed to climate change.
