Last month was the hottest January on record over the world’s land and ocean surfaces, with average temperatures exceeding anything in the 141 years of data held by the National Oceanic and Atmospheric Administration.
The record temperatures in January follow an exceptionally warm 2019, which has been ranked as the second hottest year for the planet’s surface since reliable measurements started. The past five years and the past decade are the hottest in 150 years of record-keeping, an indication of the gathering pace of the climate crisis.
According to Noaa, the average global land and ocean surface temperature last month was 2.5F (or 1.14C) above the 20th-century average. This measurement marginally surpassed the previous January record, set in 2016.
