Europe GISS Temps Since 1880
UPDATE: A separate post with graphs for each region of the world is here. (Including Europe, plus North America, South America, Africa, and Pacific regions). [end update]
Below are graphs of data from Chiefio's blog, for Europe since 1880, showing "first differences" for annual average temperature from GISS data. The first chart shows the temperature difference, year-on-year. The second chart shows the cumulative differences.
The rise around 1989 on the Cumulative chart is due to the consecutive years 1988 and 1989 having fairly high year-on-year changes. The changes were 0.79 and 0.73, respectively. Did Europe have two heat waves in succession? Or is there some bust in the data?
