As the ice was retreating at the end of the ice age, the melting was suddenly interrupted. A cold period of more than a thousand years followed.

Ocean currents have brought more heat into the northern seas after 2001. The northern extension of the Gulf Stream has warmed and probably also strengthened.

When the last ice age was over, a large glacier covering the 1000 meter deep Hardangerfjord collapsed. These events at the end of the ice age in Norway, resemble what we are about to witness in today’s Greenland.

Widespread sea ice decline within 250 years unleashed abrupt climate change during the last glacial period. A new study documents that the cause of the severity of the changes resides in the ocean. 

The jet stream is a highway for cyclones, while the sea ice edge has been thought to be a fuel station. Erica Madonnas new study shows that the fuel for cyclones is not simply linked to the ice edge.

You have very likely heard about the Gulf Stream. The Iceland-Faroe Slope Jet, you have never heard of. This current is the newest one on the map.

Exceptionally large export of sea ice through the 1300 might have triggered the onset of the Little Ice Age. Such abnormal behaviour might happen "out of the blue" from internal variability within the climate system, Martin Miles and colleagues suggests in a new study. 


Unormalt store mengder sjøis i drift sørover i byrjinga av 1300-tallet kan ha satt i gang den vesle istida, og viser eit nytt studie. Tilfeldige og spontane klimaendringar kan vere grunnen til at det kom så mykje is – som igjen sette i gang mange hundre år med kulde i Europa.

New projections of the effect of greenhouse gas emissions on Greenland and Antarctica’s role in sea level rise, gives estimations beyond the amount that has already been set in motion by Earth’s warming climate.

It is far from the Arctic to Tibet. A new study shows how variations in sea ice may influence the transport of air pollution into the Tibetan Plateau.

A new study published in Nature Geoscience shows that temperature in the Southern Ocean was more tightly linked to the extent of Antarctic glaciation during past greenhouse climates than previously thought.

A new study shows that the recent Arctic warming compares to abrupt climate change events in the distant past.
