Figure 2.4.9 Ice extent on the North and South Poles
Deviations from the long-term averages of polar surface air temperature (A, G), arctic
and antarctic sea ice extent (B, F), Northern Hemisphere (NH) frozen ground extent (C),
NH snow cover extent (D) and global glacier mass balance (E). The solid red line in E
denotes the cumulative global glacier mass balance; in the other panels it shows dec-
adal variations. Figure from IPCC, reproduced with permission [2.2].
