The Warming Earth - 2015 temperatures.
The Earth is going through an extraordinary process.... the planet is warming, the ice is melting, and the climate is changing.
There hasn't been a
new coldest year
for over 100 years, as you'll see if you click here and watch the video
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.
Most of the warming occurred in the past 35 years, with 15 of the 16 warmest years on record occurring since 2001.
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 the strongest
event, makes fifth place.
