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.

The ocean is a questionable babysitter. Kristine Flacké Haualand takes us to the cradle of midlatitude cyclones.

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.

Supercoolness is less exceptional than you may think. Seals diving under Antarctic sea ice came back with data proving they live in the supercoolest part of the world.

Though sea-level contributions may be the same, increasing the spatial resolution in models provides more details about outlet glaciers. Heiko Goelzer writes about a new study of the Greenland ice sheet. 

Stephen Outten and Ingjald Pilskog run the Bjerknes Centre for Climate Research podcast and recently talked to Igor Ezau about heatwaves and their dangers.

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.

Big data demand new tools. To find out how much CO₂ the Atlantic will take up in the future, researchers pick up an old one. The legacy of Mendel. 

Margit Simon and her colleagues have detected anthropogenic CO2 from the 1950s and onwards in sediments from the Icelandic shelf. Here she writes about their new study.

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 project will help crops and reduce flood risk for region of 365 million people.

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.

From autumn 2021, Kerim Nisancioglu's climate and sustainability course enters a whole new campus: aboard the tall ship Statsraad Lehmkuhl, in the Caribbean. But before she sets sail, Meike Becker will install observation instruments to collect data from the sea surface all around the world.

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

Development of the Norwegian Earth System Model (NorESM) is a core activity in climate research at the Bjerknes Centre. The new infrastructure project INES takes charge of the Norwegian modelling activity. 

The medal collection of three generations of Bjerknes researchers find their place at the Bjerknes Centre for Climate Research and the Geophysical Institute at UiB. See the opening June 23rd.

Whether Arctic warming influences mid-latitude weather is debated. A new study shows that the response to heating may depend on how high up the air is heated.
