The relentless challenge of global heating has again been underscored by the tally of a passing year, with 2022 ranking as one of the warmest years ever recorded and the past eight years now collectively the hottest documented by modern science.
Last year’s average temperature was about 1.15C warmer globally than levels seen in the pre-industrial era, according to the World Meteorological Organization (WMO), with searing, record heat enveloping much of Europe and Asia, which both experienced their second hottest years on record. Europe had its warmest ever summer.
The cooling influence of La Niña, a periodic climate event now in its third year that delivers brisker temperatures to parts of the globe, helped take some of the edge off the 2022 heat, with the year ranking as either the fifth or sixth hottest year on record.
