Global warming

Here you can find the data for global warming for the years 1880 to 2017.
The following graphics and tables show the global warming. For every month from 1880 until 2017 the deviations from the 1951-1980 mean temperatures are displayed.
Units are degrees Celsius.

Data source

The data are from the Goddard Institute for Space Studies of the NASA. The data are compliled on a monthly basis.


The data refer to the land-surface air temperature (without oceans). The data from 6000 weather stations are used. Some adjustments are made, e.g. to minimize nonclimatic factors in urban areas.

Latest data

November 2017 +1.07° Celsius above the average value for November from 1951 - 1980.
November 2017 is therefore the 3rd warmest November since 1880 (Beginning of the global temperature records).

Year 2017 +1.14° Celsius above the average value from 1951 - 1980 from January to November.
Year 2017 (January to November) is therefore the 2nd warmest year since 1880 (Beginning of the global temperature records).
