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...

Uptake of Carbon Dioxide from the Atmosphere
Arctic marine systems currently provide a substantial carbon sink but the continuation of this service depends critically on arctic climate change impacts on ice, freshwater inputs, and ocean acidification.

Minimum arctic summer sea ice extent
Sea ice has decreased sharply in all seasons, with summer sea ice declining most dramatically — beyond the projections of IPCC 2007.

Anomalies in Northern Hemisphere Snow Cover
Snow cover extent has continued to decline and is projected to decline further, despite the projected increase in winter snowfall in some areas.

Glacier Mass Balance
Glacier mass loss has been observed across the Arctic, consistent with the global trend.

East Siberian Arctic Shelf
The degradation of arctic sub-sea permafrost is already releasing methane from the massive, frozen, undersea carbon pool and more is expected with further warming.

Antarctic References
Images of Antarctica (left) and Greenland (right) to scale. Antarctica is 50 per cent larger than the United States or Europe. Greenland is 7 times smaller than Antarctica. There is enough ice in Antarctica to raise glob...

The Arctic Ocean
The Arctic Ocean experiences much less exchange with the atmosphere than other oceans; momentum exchange (wind drag), heat exchange and freshwater exchange are limited due to the sea ice cover.

Global Sea-level Rise
The loss of ice from the Greenland Ice Sheet has increased and will contribute substantially to global sea level rise.

Gas Arctic
The temperature regime of sub-sea permafrost is determined by the annual temperature of the surrounding seawater, just like the thermal regime of terrestrial permafrost is determined by the arctic surface temperature.

Global Carbon Storage in Soils
Arctic terrestrial ecosystems will continue to take up carbon, but warming and changes in surface hydrology will cause a far greater release of carbon.
