Thermohaline Circulation
If the large-scale ocean circulation is disturbed by processes altering heat and salinity in the Arctic Ocean, the consequences may be felt worldwide. The mechanism involved is the world-encompassing meridional overturni...

The Cryosphere, components and world maps
Snow and the various forms of ice - the cryosphere - play different roles within the climate system. The two continental ice sheets of Antarctica and Greenland actively influence the global climate over time scales of mi...

Regional changes in Arctic and Antarctic sea ice
There are major regional differences for the Arctic sea ice, with the strongest decline in ice extent observed for the Greenland Sea (10.6 per cent per decade). The smallest decreases of annual mean sea ice extent were f...

Change in sea level as a result of changes in ocean density and circulation
Changes in sea levels resulting exclusively from changes in ocean density and circulation patterns, results of atmosphere-ocean general circulation models (AOGCM) for climate change scenario A1B (this scenario assumes fu...

Sea Level Anomalies
Melting and warming will have consequences on ocean circulation. Additionally melting of inland glaciers and continental ice sheets on Greenland and Antarctica, and the thermal expansion of ocean waters are causing sea l...
