Warm 2022 makes the past eight years hottest ever recorded

World Meteorological Organization data shows last year’s average temperature was 1.15C more than pre-industrial levels

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.
