Greenhouse gas (GHG) concentrations have reached new highs, the increase has continued in 2021 too, the past seven years are on track to be the seven warmest on record, and the global sea level rise accelerated since 2013 to a new high in 2021 according to the provisional WMO State of the Global Climate 2021 report

Record atmospheric greenhouse gas concentrations and associated accumulated heat have propelled the planet into uncharted territory, with far-reaching repercussions for current and future generations, according to the World Meteorological Organization (WMO). 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.
