Now, as climate scientists warn ever more urgently that humanity must immediately transform and decarbonize our economies to avoid an unlivable future, this idea’s political moment has finally arrived. A new generation of progressive activists and lawmakers has forced debate over a Green New Deal into the national conversation. Likely 2020 Democratic presidential candidates Bernie Sanders and Cory Booker are just two of the scores of elected officials who have endorsed a Green New Deal.
