Using climate models, we develop predictions for the coming season as well as the coming century. Our scientists investigate the foundation for such predictions as well as how to best produce them.

 

Long-term projections

 

Producing long-term climate projections, means considering yet unknown emissions and societal development. That is why projections of the climate for decades or centuries ahead are done by running climate models under a range of emission scenarios.

 

This does not generate one answer, but a span in future temperatures or sea levels, depending on CO₂ emissions as well as land-use changes.

 

Such predictions are called climate projections, as they portray a future depending on specific conditions.

 

Predictions for the coming year and decade

 

We also develop climate predictions on shorter time scales, such as the coming season, year or decade. 

 

These predictions can be seen as something in-between weather forecasts and long-term climate projections. Both increasing emissions and natural variations in e.g. ocean currents must be taken into account.

 

To develop skillful climate predictions, the Bjerknes Climate Prediction Unit (BCPU) aims to bridge the gap between weather forecasting and long-term climate change projections.

 

BCPU has developed the Norwegian Climate Prediction Model (NorCPM), which is based on the Norwegian Earth System Model (NorESM).

 

Climate Futures, a center formed with a basis in the Bjerknes Centre, develops long-term predictions from ten days to ten years ahead – aiming to handle climate risk in vulnerable sectors. The idea is to establish a long-term cooperation between businesses and industry, governmental organizations and research institutes.
