Climate Change - 2015 - Warmest Year in Modern Record

The year 2015 ranks as Earth’s warmest year since records began in 1880.

This is reported by scientists from NASA and the National Oceanic and Atmospheric Administration. 

The average surface temperature has risen about 1.0 degree Celsius since the late-19th century.

Globally-averaged temperatures in 2015 beat the previous record set in 2014 by 0.13 degrees Celsius

NASA analysis estimates 2015 was the warmest year with 94% certainty.



2015 was the first time the global average temperature was 1 degree Celsius or more above the 1880-1899 average.

Global annual average temperature relative to 1961-1990 based on the three major global temperature datasets (HadCrut4, NASA GisTEMP and NOAA).

9 of the 10 warmest years in the record have occurred in the 21st century.

From earlier years, only 1998, affected by a strong El Nino event, makes fifth place.
