Climate Doom Is Out. ‘Apocalyptic Optimism’ Is In.

Focusing on disaster hasn’t changed the planet’s trajectory. Will a more upbeat approach show a way forward?

The philanthropist Kathryn Murdoch has prioritized donations to environmental causes for more than a decade. She has, she said, a deep understanding of how inhospitable the planet will become if climate change is not addressed. And she and her colleagues have spent years trying to communicate that.

“We have been screaming,” she said. “But screaming only gets you so far.”

This was on a morning in early spring. Murdoch and Ari Wallach, an author, producer and futurist, had just released their new PBS docuseries, “A Brief History of the Future,” and had hopped onto a video call to promote it — politely, no screaming required. Shot cinematically, in some never-ending golden hour, the six-episode show follows Wallach around the world as he meets with scientists, activists and the occasional artist and athlete, all of whom are optimistic about the future. An episode might include a visit to a floating village or a conversation about artificial intelligence with the musician Grimes. In one sequence, marine biologists lovingly restore a rehabbed coral polyp to a reef. The mood throughout is mellow, hopeful, even dreamy. Which is deliberate.

“There’s room for screaming,” Wallach said. “And there’s room for dreaming.”

“A Brief History of the Future” joins some recent books and shows that offer a rosier vision of what a world in the throes — or just past the throes — of global catastrophe might look like. Climate optimism as opposed to climate fatalism.

Hannah Ritchie’s “Not the End of the World: How We Can be the First Generation to Build a Sustainable Planet” argues that many markers of disaster are less bad than the public imagines (deforestation, overfishing) or easily solvable (plastics in the oceans). In “Fallout,” the television adaptation of the popular video game that recently debuted on Amazon Prime Video, the apocalypse (nuclear, not climate-related) makes for a devastated earth, sundry mutants and plenty of goofy, kitschy fun — apocalypse lite.
