To interpret what is happening in more detail, the following is a useful key
Year. In the centre of the circle is the year of the observations, starting in 1900.
Global temperature trend: top right of the picture.
Temperature anomalies. Moving out from the centre are five concentric rings, corresponding to the size of the anomaly: from – 2.0oC through –1.0oC, 0.0oC, +1.0oC, to +2.0oC. Individual country values are expresses as spokes emanating from the centre, with colours expressing the scale of the deviations, (negative = blue, positive = red)
Geography. The individual countries should be visible in full screen mode, but for a quick impression of what is happening in global differences, note that the quadrants can be summarised as follows. Moving clockwise from 12.00, we find:
Bottom right: Africa
Bottom left: Europe
Top left: The Americas and Oceania
The animation has the virtue of demonstrating in visual form the potential significance of global warming in provoking increasing numbers of extremes, which may nevertheless vary substantially from year to year, country to country, and continent to continent.
