State of Climate in 2021: Extreme Events and Major Impacts

The past seven years are on track to be the seven warmest on record, according to the provisional WMO State of the Global Climate 2021 report, based on data for the first nine months of 2021. A temporary cooling “La Niña” event early in the year means that 2021 is expected to be “only” the fifth to seventh warmest year on record. But this does not negate or reverse the long-term trend of rising temperatures.
Global sea level rise accelerated since 2013 to a new high n 2021, with continued ocean warming and ocean acidification.
