The past predicts the future: Lessons on climate sensitivity
Equilibrium climate sensitivity is a key predictor of climate change. However, it is not very well constrained, either by climate models or by observational data. The reasons for this include strong internal variability on many timescales, non-stationary forcing and the climate system being out of equilibrium with the changes in the radiative forcing. Geological records could potentially provide an additional constraint on climate sensitivity, but slow and fast feedbacks complicate the interpretation of those records. In the geological past, the forcing timescales were different than at present, suggesting that the response may have behaved differently. Do these insights constrain the climate sensitivity relevant for the present day - and eventually help to predict future climate? In this presentation I will review the progress made in theoretical understanding of climate sensitivity and on the estimation of climate sensitivity from geological records.
Anna heeft Natuurkunde in Duitsland gestudeerd en is daarna in de Physics of Fluids group bij de Universiteit Twente gepromoveerd op turbulente stromingen. Na haar promotie heeft ze haar focus op oceaan stromingen en klimaat gelegd en is in Utrecht bij het IMAU komen werken. Ze heeft een Veni beurs ontvangen om oceaanstromingen in het geologische verleden te onderzoeken.
