Carbon System research theme

Understanding climate
for the benefit of society

icon carbon climate

The processes that regulate the flows of carbon in the earth system on multiple timescales.

Research focus

How much of the human induced CO₂ emissions are taken up by the ocean?
What are the consequences of the oceanic CO₂ uptake in terms of ocean acidification?
What controls natural variations of the carbon cycle?
What do biogeochemical tracers tell us about water mass formation and ocean circulation?
What are the feedbacks between the climate system and biogeochemical processes in the ocean and on land?
How to include the marine sedimentary paleoclimate record in global ocean models?
How to include vegetation and soils in global climate models?

Keywords: carbon cycle, climate feedbacks, sustainability, glacial cycles, nutrients, oxygen.

Outlook

“The transformation to a low carbon society has to happen in the next ten years and insight into the carbon system is essential for this process”, says Are Olsen, leader of the Carbon System research theme.

“It is essential for defining the risks associated with the various possible emission pathways, for planning climate actions, and for evaluating their efficiency in reducing atmospheric CO₂.

Our central goal is to provide this insight to society by developing and using the best possible models and observations.”

New PhD thesis solves mysteries around large abrupt climate changes

Henrik Sadatzki defends on Friday 15.02.2019 his thesis for the PhD degree at the University of Bergen. The thesis is entitled: “Sea ice variability in the Nordic Seas over Dansgaard–Oeschger climate cycles during the last glacial – A biomarker approach”.

Caroline Clotten defends on Thursday, December 7th 2017 her PhD dissertation at the University of Bergen with the title: "Pliocene sea ice evolution in the Iceland and Labrador Sea – A biomarker approach".

That the ocean slows down global warming by absorbing CO2 from the air, is pure chemistry. But to find out how much, you have to know how the ocean moves. Friederike Fröb's PhD shows that both weather and ocean currents play a role.

The researchers at the Bjerknes Centre for Climate Research work with observations, theory and climate models. The research is organised in four thematic groups:

Global climate – led by Stefan Sobolowski
Polar climate – led by Kerim Nisancioglu
The Carbon system – led by Are Olsen
Climate hazards – led by Marius Årthun
