We present a sea-ice record from northern Greenland covering the past 10,000 years. Multiyear sea ice reached a minimum between ~8500 and 6000 years ago, when the limit of year-round sea ice at the coast of Greenland was located ~1000 kilometers to the north of its present position. The subsequent increase in multiyear sea ice culminated during the past 2500 years and is linked to an increase in ice export from the western Arctic and higher variability of ice-drift routes. When the ice was at its minimum in northern Greenland, it greatly increased at Ellesmere Island to the west.

Sea levels could rise up to 5 feet by the end of this century, driven by warming in the Arctic and the resulting melt of snow and ice, according to this study by the International Arctic Monitoring and Assessment Program (AMAP). This is more than two and a half times higher than the 2007 projection of a half to two feet by the Intergovernmental Panel on Climate Change.

On 27 May 2010, with crude oil gushing into the Gulf of Mexico after the explosion of BP’s Deepwater Horizon oil rig, the Obama administration announced it would pause offshore drilling plans in the Arctic Ocean, one of the planet’s most pristine ecosystems.

Ice Loss Started In Early 20th Century And Accelerated Over The Last Three Decades, Say Researchers

Washington: Arctic sea ice is at its record low in the recent geologic history, a major international study has claimed. The first comprehensive history of Arctic ice, carried out by a team of scientists from five countries, found that the recent retreat is the worst in thousands of years.

Our current concepts of abrupt climate change are strongly influenced by compelling palaeoclimate evidence for events like the Younger Dryas, in which massive changes in climate occurred essentially instantaneously.

A thousand years after the last ice age ended, the Northern Hemisphere was plunged back into glacial conditions. For 20 years, scientists have blamed a vast flood of meltwater for causing this

Every winter the Arctic ice cap is penned in by curved barriers of ice spanning the straits that lead out of the Arctic Ocean. Now it seems that some of these ice arches are failing to form. The resulting exodus of sea ice into the Atlantic and Pacific could affect ocean circulation and marine life.

The frozen Arctic provides immense services to all nations by cooling the earth

Detailed studies of ancient climate have revealed that the onset of Europe's "Big Freeze", 13,000 years ago, was anything but glacial.
