NASA & NOAA: 2016 Warmest Year On Record

Earth’s 2016 surface temperatures were the warmest since modern recordkeeping began in 1880, according to independent analyses by NASA and NOAA, marking the third year in a row to set a new record for global average surface temperatures.

“Globally-averaged temperatures in 2016 were 1.78 degrees Fahrenheit [0.99 degrees Celsius] warmer than the mid-20th century mean. This makes 2016 the third year in a row to set a new record for global average surface temperatures,” NASA said.

“The 2016 temperatures continue a long-term warming trend, according to analyses by scientists at NASA’s Goddard Institute for Space Studies [GISS] in New York. NOAA scientists concur with the finding that 2016 was the warmest year on record based on separate, independent analyses of the data.

“Because weather station locations and measurement practices change over time, there are uncertainties in the interpretation of specific year-to-year global mean temperature differences. However, even taking this into account, NASA estimates 2016 was the warmest year with greater than 95 percent certainty.”

“2016 is remarkably the third record year in a row in this series,” said GISS Director Gavin Schmidt. “We don’t expect record years every year, but the ongoing long-term warming trend is clear.”

“The planet’s average surface temperature has risen about 2.0 degrees Fahrenheit [1.1 degrees Celsius] since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.

“Most of the warming occurred in the past 35 years, with 16 of the 17 warmest years on record occurring since 2001.

“Not only was 2016 the warmest year on record, but eight of the 12 months that make up the year — from January through September, with the exception of June — were the warmest on record for those respective months.

“October, November, and December of 2016 were the second warmest of those months on record — in all three cases, behind records set in 2015.
