The month of September was the hottest on record around the world in a year that is expected to be the hottest in history after the warmest-ever global temperatures during the Northern Hemisphere summer.
September's average surface air temperature of 16.38 degrees Celsius was 0.93 degrees above the 1991-2020 monthly average and 0.5 degrees above the previous record set in 2020, the European Union’s Copernicus Climate Change Service (C3S), said in a report published Thursday.
