According to the National Oceanic and Atmospheric Administration, 2015 easily broke the previous record for the warmest year that had been set just the previous year.
During 2015, the average temperature across global land and ocean surfaces was 1.62 Fahrenheit (0.90 Celsius) above the 20th century average,” said the NOAA report.
“This was the highest among all years in the 1880-2015 record.”
Compared to 2014, last year was 0.29 Fahrenheit (0.13 Celsius) warmer, the “largest margin by which the annual global temperature record has been broken.”
