‘A deranged pyroscape’: how fires across the world have grown weirder

As the planet heats, combustible landscapes will dry and ignite. Less fire-prone lands, such as Greenland, will start catching fire, too. Environmentalists now urge us to imagine the whole world aflame. If our old picture of climate breakdown was a melting glacier, our new one is a wildfire. Its message is simple and urgent: the higher we crank up the heat, the more everything will burn – call this the “thermostat model”. With headlines reporting enormous fires from Sacramento to Siberia, it’s easy to feel that we’re already on the brink of a devastating global conflagration.
