Abstract:
Clouds are critical for understanding the historical and future evolution of climate. Clouds are the largest uncertainty in historical climate radiative forcing, due to uncertainties in how anthropogenic aerosols impact cloud processes and ultimately cloud radiative effects. How clouds respond to climate change is the largest uncertainty in climate feedbacks, which determine the future response of the climate system. Cloud forcing and feedback will be explored in the context of the Community Earth System Model (version 2) recently released as part of the CIMP6 process. Forcing and feedback are also key for understanding how CESM2 evaluates very well against current climate and also why CESM2 has a high climate sensitivity, outside of the 'likely' IPCC range. The applicability of these results to other models, the IPCC assessment and generality for the climate system will be explored.
What is the Joint Oslo Seminar (JOS):
Atmospheric and climate sciences have a stronghold in Oslo among the four institutions University of Oslo, the Meteorological Institute, CICERO and NILU. This joint seminar invites renowned international experts to contribute to an informal series of lectures, meant to create interaction with the Oslo atmospheric and climate science community on recent highlights and analysis in the field.
