Yesterday I was in Paradise, California, a town that was nearly destroyed by a wildfire that killed 86 people. Climate change is lengthening wildfire seasons, increasing the heat and drought that fuels the fires, and putting more towns and lives at risk. If there’s any silver lining in this terrible tragedy in this beautiful town it is that, I hope, the people of the United States, the people of the world, understand that we need bold and aggressive action — a Green New Deal — to combat climate change.
