2015 Annual Global Climate Report

January-December 2015 Global Temperature Percentiles Map

The globally averaged temperature, over land and ocean surfaces for 2015, was the highest since record keeping began in 1880, according to NOAA scientists. During the final month, the December combined global land and ocean average surface temperature departure from average was the highest on record for any month in the 136-year record.

This summary, developed by scientists at NOAA's National Centers for Environmental Information, is part of the suite of climate services NOAA provides to government, business, academia, and the public to support informed decision making.

In an independent analysis of global temperature data, also released today, NASA scientists also found 2015 to be the warmest on record.
