Last week, United Nations General Secretary António Guterres coined an arresting new term. The era of global warming has ended, he declared dramatically, and the era of “global boiling” has arrived.

Marine heatwaves are devastating the world’s third-largest coral reef, off Florida. And as greenhouse emissions keep rising, it means many even hotter summers await us.
