Near the end of the last ice age, the global sea level rose 12–14 meters in less than 350 years. New research traces almost half of the ice melt to Norway and the Barents Sea.

The oceans twilight zone, the dimply lit part between the sunlit surface and the dark abyss is home to mysterious ways of life. In a recent Nature comment an international group of scientists propose that the exploration of this region should be pursued in a collective joined up way across the international scientific community.

Eirik Vinje Galaasen and colleagues presents a new study in Science that reveals gradual warming could trigger the ocean circulation to enter a more variable and chaotic state. 

Inland Antarctic ice contains volumes of water that can raise global sea levels by several metres. A new study published in the journal Nature shows that glacier ice walls are vital for the climate, as they prevent rising ocean temperatures and melting glacier ice.

The freshening of the western North Atlantic from ice melt started as early as in the 1940's, new study indicates.

In the last interglacial, the sea level rose to ten meters higher than today. For the first time, researchers have now traced the extra water to Antarctica.

In the coldest years of the last ice age, the ice cap reached the British Isles and Poland. New research has revealed a green patch much closer to the North Pole. Part of a peninsula in Svalbard was free from ice.

The Gulfstream makes northern Europe warmer by transporting heat. This is well known. New research shows that the sea surface temperature also affects storm tracks as far away as the Pacific.

A newly published study in Nature Communications shows an important new understanding of the climate system that will allow us to better understand past climate variability. The results were uncovered by expeditions between the North Pole and Antarctica.

The living conditions for marine microorganisms in the Southern Ocean may dramatically worsen by the end of the century. More acidic water can make their territories shallower.

A new study provides evidence of substantial variations in past sea ice cover in the Norwegian Sea, instrumental for several abrupt climate changes between 32,000 and 40,000 years ago. 

Vannet som strømmer inn i Barentshavet og Polhavet er blitt varmere det siste hundreåret. Fra år til år er det likevel strømmens styrke som regulerer hvor mye varme sjøisen utsettes for.  

Large variability is observed in the northern extension of the Gulf Stream, but so far there are no signs of a weakened circulation.

The temperature of the subpolar North Atlantic is going lower. This implies decreasing cod stocks in the Barents Sea over the next five to six years, shows study.

The Arctic is about to shrink, shows a new study, as an important part of the Arctic Ocean shifts over to an Atlantic climate regime. The rapid climate shift occurs in the northern Barents Sea—the Arctic warming hotspot where the surface warming and loss of winter sea ice is largest in the entire Arctic. 

The Mediterranean region is vulnerable to a global warming of two degrees, a new study shows. At 1.5 degrees or less, climate models do not respond in a similar fashion.

With global warming, ocean circulation in the Atlantic Ocean is generally thought to weaken. New research shows that less sea ice off the coast of Greenland may work against this.

On TV weather maps we see low pressure centers as circles resembling tree-rings, with long tails of red warm fronts and blue cold fronts. But what came first – the low or the fronts?
