The sheet is a mass of glacial land ice and is an integral part of Earth’s climate system helping to reflect the sun’s warm rays and keep the Arctic cool, regulating sea level, and influencing ...
The recent arctic blast has pushed ice cover on the Great Lakes to levels not seen since 2022. Lake Erie in particular has become mostly ice covered in quick order. As of January 23, ice cover has ...
Younger ice (first-year ice) is shown in darker shades, while older ice (four-year or older) is shown in white. This visual shows the Arctic sea ice change and the corresponding absorbed solar radiation change during June, July, and August from 2000 through 2014. The Arctic ice pack is the sea ice cover of the Arctic Ocean and its vicinity. The ...
Russia's Arctic and Antarctic Research Institute has compiled ice charts dating back to 1933. Today, scientists studying Arctic sea ice trends can rely on a fairly comprehensive record dating back to 1953, using a combination of satellite records, shipping records, and ice charts from several countries.

Sea ice in the Arctic region has declined in recent decades in area and volume due to climate change. It has been melting more in summer than it refreezes in winter. Global warming, caused by greenhouse gas forcing is responsible for the decline in Arctic sea ice. The decline of sea ice in the Arctic has been accelerating during the early ...
Svalbard, a chain of Norwegian islands located well inside the Arctic Circle, experiences total darkness for several months of the year. Add heavy snow, way-below-freezing temperatures and the ...
The Arctic sea ice covers less area in the summer than in the winter. The multi-year (i.e. perennial) sea ice covers nearly all of the central deep basins. The Arctic sea ice and its related biota are unique, and the year-round persistence of the ice has allowed the development of ice endemic species, meaning species not found anywhere else.
For now, at least, the north pole is covered in sea ice 365 days per year. If C02 emissions are reduced considerably moving forward, ice will remain in the Arctic over most summer months.
