Here at the U.N. climate talks in Katowice, the U.S., Saudi Arabia, Russia and Kuwait have blocked language “welcoming” October’s landmark IPCC climate report, which warned of the catastrophic effects of a global temperature increase of 1.5 degrees Celsius—or 2.7 degrees Fahrenheit—beyond which global crises could unfold at a rapid pace. The four countries rejected using the word “welcome,” insisting that members instead “note” the findings of the widely cited U.N. report.
