Pressure continues to mount on Congress to get its act together on climate change. The latest salvo came on Thursday, as 626 groups delivered a letter to every member of Congress laying out their support for a Green New Deal and their demands. The list of groups includes heavy hitters in the climate and policy world like Greenpeace, the Center for Biological Diversity, 350, and Indivisible. Representative Alexandria Ocasio-Cortez popularized the proposal for a Green New Deal to wean the U.S. off fossil fuels in a little over a decadeduring the midterm election, and protests on Capitol Hill have galvanized support.
