About

Kjetil Aas is a climate researcher and climate science disseminator with a broad scientific background.

His work focuses on modeling the climate system with the goal of better understanding climate change, its impacts, and how it can be mitigated.

An experienced climate communicator, Kjetil is motivated by making state-of-the-art knowledge about climate accessible to a broader audience.

Kjetil has a PhD in Geosciences from the University of Oslo as well as a teacher’s education in math and physics. He uses and develops climate models (particularly the Norwegian Earth System model, NorESM). With a specialization in land surface modelling, he has worked particularly on the role of vegetation and of the cryosphere (snow, ice, and permafrost) in the climate system.

Projects

EYE-CLIMA - Verifying emissions of climate forcers

The EU funded project EYE-CLIMA aims to improve estimates of emissions and removals of the most important greenhouse gases, namely, co₂, methane, N2O and six F-gases, as well as the aerosol black carbon.

CN-coESM - Permafrost, wildfire, climate change processes, interactions, and feedbacks: co-development of Earth System Models between China and Norway

Arctic-boreal regions are warming at a much faster rate than the global mean. Arctic-boreal ecosystems combined are the largest reservoirs of terrestrial carbon and have long snow covered seasons. As a result, processes involved in these ecosystems have a high significance for global climate.

PROVIDE: Paris Agreement Overshooting – Reversibility, Climate Impacts and Adaptation Needs

Overshooting the Paris Agreement 1.5°C temperature thresholds is a distinct possibility, but what does such temperature overshoots imply for the planning and design of adaptation action? The PROVIDE project will deliver information on overshoot scenarios and expected impacts and their reversibility, covering both sectors and geographical regions. The information will directly feed into adaptation action.

ESM2025: Earth system models for the future

The ESM2025 EU-funded research project aims to build a new generation of Earth system models better fitted to support the development of mitigation and adaptation strategies in line with the Paris Agreement.

Research groups

Climate Mitigation

The research group works to understand the trends and drivers of historical and future emissions of greenhouse gases and short-lived climate forcers, and their effect on the climate.

Climate System

The research group conducts atmospheric research, with special emphasis on understanding the processes and physical impacts of the climate system.
