War is reshaping our world. Will we harness that urgency for climate action or succumb to a final, deadly oil and gas boom?

NOSTALGIA FOR EMPIRE is what seems to drive Vladimir Putin — that and a desire to overcome the shame of punishing economic shock therapy imposed on Russia at the end of the Cold War. Nostalgia for American “greatness” is part of what drives the movement Donald Trump still leads — that and a desire to overcome the shame of having to face the villainy of white supremacy that shaped the founding of the United States and mutilates it still. Nostalgia is also what animates the Canadian truckers who occupied Ottawa for the better part of a month, wielding their red-and-white flags like a conquering army, evoking a simpler time when their consciences were undisturbed by thoughts of the bodies of Indigenous children, whose remains are still being discovered on the grounds of those genocidal institutions that once dared to call themselves “schools.”

This is not the warm and cozy nostalgia of fuzzily remembered childhood pleasures; it’s an enraged and annihilating nostalgia that clings to false memories of past glories against all mitigating evidence.

Climate inaction was never really about denial. Rich countries just thought poorer countries would bear the brunt of the crisis.

MANY PEOPLE HERE think they are safe from climate change, the journalist from a German newspaper explained to me. They don’t see it as an immediate threat, like Covid-19. They see the Greens as scolds who want to take away their cheap holidays. “What do you have to say to them?”

The question came via video call in late June, and I was, at that very moment, pickled in my non-air-conditioned home, gripped by a heatwave that would, before the week was done, kill about 500 people in British Columbia, Canada, and cook perhaps a billion marine creatures on scorching shorelines. Over the years, I have faced many such “why should I care” questions, and I usually try to reach for some kind of moral argument about our responsibility to fellow humans even when we aren’t immediately impacted. But because I was far too hot and angry for high-mindedness, what I had to say instead was “Give it a minute.”
