Climate science, not to mention the need to set the economy on a self sustaining and equitable trajectory, should tell us that a Green New Deal is long overdue. Its realization, in its robust version, will take something similar to what it took to legislate the New Deal in the 1930s — an aroused and informed public, an engaged labor movement, a multi-racial coalition of the many, and a political realignment at the national level in a progressive and left direction. A big challenge, but within reach.
