2016 Was the Warmest Year on Record

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.
