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?

Um, I think you need to QA check these. They seem to be a bit afflicted with hockey stickism ;-)
ReplyDeleteIn particular, the "All Pacific" data give 0.48 as the max value in 2010 for dT/dt cumulative, while your graph has it at a little under 1.5 c and the 'zero touch' in '93-'95 looks like 0.5, 0.75, 0.5 C to me ...
Haven't checked the others yet, but they look more tilted that I would expect...
