The icebreaking date for the Tornio River in Finland has been recorded since 1693. With the increased greenhouse effect, impacts on the cryosphere are likely. One impact will be less ice on rivers and lakes. Freeze-up dates will be delayed, and break-up will begin earlier. The period of river-ice could be shortened by up to a month. Many rivers within the temperate regions could become ice-free or develop only intermittent or partial ice coverage...

Climate change, due to increased concentrations of greenhouse gases in the atmosphere, has not lead as clear changes in the Antarctic as in the Arctic. Some of the ice shelves of the Antarctic peninsula have split up and started moving more rapidly, but the analyses of the Antarctic ice sheet are inconclusive. The projected climate situation in 2090 are presented in this figure, the temperatures are annual values from the NCAR-CCM3 model, ensembl...

Changes in the polar regions can cause more warming in the entire planet earth system through feedback effects. One such effect is the reduction of ice and snow due to warmer temperatures. When the white and gray snow and ice disappears, less sun rays are reflected out and instead the heat is absorbed by land and sea - which causes further increase in the warming.

Climate change, due to increased concentrations of greenhouse gases in the atmosphere, has lead to increased temperatures and large scale changes in the Arctic. The Arctic sea ice is decreasing, permafrost thawing and the glaciers and ice sheets are shrinking. The projected climate situation in 2090 are presented in this figure, the temperatures are annual values from the NCAR-CCM3 model, ensemble averages 1-5 for the SRES A2 experiment. The ice ...
