Spurred by climate change and heat from a monster El Niño, the global average surface temperature last year was 0.94 degrees Celsius (1.69 degrees Fahrenheit) higher than the 20th century average of 13.9° C (57° F). That slightly edges out the previous titleholder, 2015, by 0.04 degrees C (SN: 2/20/16, p. 13). Eight months during 2016 set new all-time highs, including July and August, which tied for Earth’s warmest months on record, scientists from the National Oceanic and Atmospheric Administration and NASA reported January 18.
