Like so many others, I’ve been energized by the bold moral leadership coming from newly elected members of Congress like Alexandria Ocasio-Cortez, Ilhan Omar, Rashida Tlaib, and Ayanna Pressley in the face of the spiraling climate crisis and the outrageous attacks on unarmed migrants at the border. It has me thinking about the crucial difference between leadership that acts and leadership that talks about acting.

I’ll get to the Green New Deal and why we need to hold tight to that lifeline for all we’re worth. But before that, bear with me for a visit to the grandstanding of climate politics past.

It was March 2009 and capes were still fluttering in the White House after Barack Obama’s historic hope-and-change electoral victory. Todd Stern, the newly appointed chief climate envoy, told a gathering on Capitol Hill that he and his fellow negotiators needed to embrace their inner superheroes, saving the planet from existential danger in the nick of time.
