"BELEM, Brazil — The world has changed dramatically in the decade since leaders celebrated a historic climate agreement in Paris a decade ago, but not quite in ways they expected or wanted.

Earth’s warming climate has gotten nastier faster than society has been able to wean itself from burning the coal, oil and natural gas that emits carbon pollution that triggers global warming, several scientists and officials said.

There’s been progress — more than a degree Celsius (2 degrees Fahrenheit) has been shaved off future warming projections since 2015 — but the lack of enough of it will be a big focus for the next two weeks as diplomats gather in Belem, Brazil, for annual United Nations climate negotiations.

“I think it’s important that we’re honest with the world and we declare failure,” said Johan Rockstrom, director of the Potsdam Institute for Climate Research in Germany. He said warming’s harms are happening faster and more severely than scientists predicted."
