2010s warmest decade on record, NASA/NOAA say; 2019 second hottest year

The 2010s were the warmest decade on record, government researchers announced on Wednesday, as global surface temperatures continued their rise linked to greenhouse gas emissions. The five warmest years on record occurred in the last five years, the researchers said, including 2019, which was second-warmest, exceeded only slightly by 2016.

Studies released by the National Aeronautics and Space Administration and the National Oceanic and Atmospheric Administration showed that global average surface temperatures last year were nearly 1 degree Celsius (1.8 degrees Fahrenheit) higher than the average from 1951 to 1980.
