Climate Change - July 2015

July 2015 was the warmest month in the modern temperature record.

The average temperature for July 2015 across global land and ocean surfaces was 1.46°F (0.81°C) above the 20th century average, according to the United States National Oceanic and Atmospheric Administration.

They said: "As July is climatologically the warmest month for the year, this was also the all-time highest monthly temperature in the 1880–2015 record, at 16.61°C, surpassing the previous record set in 1998 by 0.08°C."




Globally-averaged temperatures for the year 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).
