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.

Extreme stratospheric events impact weather at the surface. New research suggest the troposphere causes the events.

Record breaking heat wave in Siberia amidst of COViD-19 pandemia may seriously exacerbate the death toll

Due to the world social distancing situation, the annual Ocean Outlook goes online with virtual presentations on topics and scoping the next full meeting: The near future of our oceans.

The water entering the Barents Sea is not as cooled down as it used to. This has a large effect on the climate in the area and may lead to fish and other marine life migrating, shown in a Nature Climate Change study.

This week, the University of Bergen became part of a group of the world's leading climate research institutions.

The Arctic sea ice is on the move all year. It expands to its maximum during March and reaches its minimum in September. The variation during the year, and from year to year, depends on wind, weather and ocean currents. But the Arctic is changing.  
 

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.
