Projected rise in the Mean Annual Surface Air Temperature
1990 2090 in degrees centigrade
29. Arctic warming: mean annual air temperature rise projected
for northern latitudes between 1990 and 2090 according to the
Arctic Climate Impact Assessment (2004). Darker shading indicates
relatively great temperature changes in the Arctic
parts of the globe behave differently. In the polar regions, for
example, the warming trend has been greater than elsewhere;
and according to recent estimates, Arctic warming over the next
century may be double the global average. Figure 29 shows the
projected surface air temperature rise for northern latitudes
from AD 1990 to 2090 according to the Arctic Climate Impact
Assessment (ACIA). The temperature rise is likely to be greatest
