Dear all,

The next BCCR Monday Seminar will be given by Jorge Alvarez-Solas from the Institute of Geosciences in Spain. He will present his work on "Modelling Earth's ice sheets stability diagrams". The seminar will take place in the usual BCCR seminar room (4th floor of the West wing) at 11:00.

We hope to see you there!

 Best regards,

Julia and Robin

 
Abstract

Previous work has shown that both the Antarctic Ice Sheet (AIS) and the Greenland Ice Sheet (GrIS) display hysteresis behavior, which means that if ice is lost due to an increase of temperature, a comparatively larger decrease is needed to recover the original state. This implies that the ice-sheet volume is multistable with respect to temperature and that the ice loss could be largely irreversible. I will show quasi-equilibrium simulations of these ice sheets together with the Laurentide and Eurasian paleo-ice sheets ran with the 3D thermomechanical ice-sheet model Yelmo. Then by finding the adequate mathematical shape of the stability diagrams I will focus on how an emulator can be built for the transient modelling of these ice sheets throughout the Quaternary

 Speaker information

I did my PhD in the LSCE (Laboratoire des Sciences du Climat et de l'Environnement) in France, focusing on the millennial abrupt climate change of the last glacial period. I continued with several post-docs in the faculty of physics of the Complutense University of Madrid, where I became Assistant Professor in 2019. Then, in 2023, I moved to the Spanish Research Council at the Geoscience Institute, also in Madrid. My research interests include ice-sheet and climate modelling for Heinrich and Dansgaard-Oeschger events, but also the glacial cycles and the future of the climate-cryosphere interactions
