| Abstract: | The spatial extent and volume of global snow and ice cover at present and during glacial conditions are reviewed for each of the principal components (snow cover, land ice, sea ice and permafrost). The state of global monitoring of snow and ice conditions is shown to be adequate for some variables, but unsatisfactory for others. Recent trends are reported and expected changes projected for increasing concentrations of greenhouse gases are examined. |
