2016 was the hottest year on record, continuing a decades-long warming trend. Scientists at NASA’s Goddard Institute for Space Studies (GISS) analyzed measurements from 6,300 locations and found that Earth’s average surface temperature has risen about 2 degrees Fahrenheit (1.1 degrees Celsius) since the late-19th century, largely a result of human emissions into the atmosphere. Scientists at the National Oceanic and Atmospheric Administration (NOAA) separately analyzed the data and came to the same conclusion.
Eight of the 12 months – from January through September, with the exception of June – were the hottest of those respective months on record. October, November and December of 2016 were the second hottest of those months on record – in all three cases, behind records set in 2015.
