Figure 2 How much, and in what sense regional temperatures have systematically changed, around the world, in the last fifty years. The contours express the temperature change in degrees C: in this case, the difference between the mean temperature for 1981-1997 and that for 1951-1980. The mean temperature increase in this time, averaged over the globe, was about 0.4°C. The greatest changes, as expected, were generally at higher latitudes, although surface readings over isolated portions of the North Atlantic and North Pacific Oceans have cooled by about as much.
