Sediments are archives of past climates – provided you know when they were deposited. Sevasti Eleni Modestou uses lead to clock past events.

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.

24 meter deep sediment core gives the image of a surprisingly rich flora.

“The warming threshold for significant Greenland Ice Sheet retreat could be less than 1°C above the present”

Autonomous ocean gliders on a year-round journey to unravel mysteries about the Lofoten Vortex

"Imagine turning into a liquid on a hot summer day", writes Willem Van der Bilt. To avoid that, some algae change their body fat. Fat in fossile algae reveal that Svalbard was seven degrees warmer 10,000 years ago.

The conference Arctic Frontiers in Tromsø gathers politicians, business and scientists on Arctic issues the last week of January. Not in Tromsø? Find the live streams here. ​

Professor Camille Li on what leads storms like Brendan or Didrik our way.

Perhaps nowhere is the difference between cities and their surroundings greater than in the Arctic. Igor Ezau writes about a new study attempting to connect the environmental impact of Arctic cities with socio-economical decisions and policy governing city growth and decay.

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

Leaving Christmas preparations and northern winter storms behind, geologists from Bergen have travelled to the far south. On the Kerguelen Islands in the Southern Ocean, they will search for the westerlies of ancient times. 

Kristian Vasskog's group found marine sediments higher on the island Karmøy than they thought the sea had reached. Southern parts of the island must have escaped the ice age much earlier than areas nearby.

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.

Changing winds influence the heat exchange between the atmosphere and the ocean. A new study by Fumiaki Ogawa and Thomas Spengler shows how important it is to consider extratropical cyclones and cold air outbreaks when calculating air-sea fluxes.

In a number of European countries, there is a clear imbalance between long-term disaster risk reduction and short-term preparation, new study finds. More data allows for better planning, but is not enough. Jenny Sjåstad Hagen emphasizes the importance of data interoperability. 

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.

Erik Kolstad and Scott Bremer organise training in transdisciplinary climate adaptation research for early career researchers.

The yearly lecture at the Norwegian Academy of Letters and Sciences.

The natural climate system has mechanisms that can abruptly trigger change. New research suggests that spontaneous cooling may have caused Arctic glaciers to grow long before the Little Ice Age, without external forcing.

This summer has produced extreme melts on the Greenland ice and Arctic sea ice. The researchers of the ice2ice project sees parallels to prehistoric, extremely rapid changes in climate.
