Temperature variability revisited

Here's another way of looking at worldwide temperature for a single year. Each dot shows a comparison between actual temperature in 2010 and average temperature.

Temperature Analomies

The average temperature shift for LAND SURFACES in 2010 was 1.7 degrees, and for OCEANS was 0.9 degrees. You can see though that this shift was unevenly distributed. Large red circles show places where the temperature was 4 or 5 degrees hotter than the base period -- mainly Canada, Saharan Africa, and the Middle East. Blue dots show where the temperature was cooler, including Europe, part of Siberia, and the Eastern Pacific Ocean.
