Can You Even Call Deadly Heat ‘Extreme’ Anymore?

David Wallace-Wells: “For a few years, I’ve startled people by pointing out that over half of all of the emissions from the burning of fossil fuels that have ever been produced in the history of humanity have been produced in the past 30 years — since Al Gore published his first book on warming; since the U.N. established its climate-change body, the I.P.C.C.; since the premiere of ‘Friends.’”

“But it is perhaps even more astonishing to consider just how fast the temperature is rising. As recently as 2015, the 10-year average of global temperatures showed, according to the I.P.C.C., warming of 0.87 degrees Celsius above the preindustrial average. Just five years later, it had jumped to 1.09 — 25 percent higher in half a decade.”
