The United Nations warns in a new report that record levels of heat-trapping greenhouse gases led to planetary-scale changes on land, at sea and in the atmosphere in 2022. The World Meteorological Organization’s State of the Global Climate report, released on Earth Day, found the years 2015 through 2022 were the eight warmest on record, despite the cooling impact of La Niña over much of that period. Antarctic sea ice fell to its lowest extent on record, glaciers retreated at an accelerating pace, and ocean heat content reached a new record high last year. The WMO warns sea level rise due to human activity is set to continue for millennia.
