About

Gilles Ramstein is a leading figure in climate science, renowned for his groundbreaking work on past climate dynamics and the role of ice sheets in Earth’s system. His research primarily focuses on paleoclimatology, using advanced climate models to reconstruct ancient climates and understand the mechanisms driving major climatic shifts, such as glacial-interglacial cycles. A key contribution is his pioneering use of coupled climate-ice sheet models to demonstrate how changes in atmospheric CO₂ and orbital forcing trigger ice sheet collapse, profoundly influencing sea level and global circulation. His work has been instrumental in revealing the sensitivity of the Greenland and Antarctic ice sheets to warming, with his most cited papers collectively amassing thousands of citations. Notably, his studies on the Eocene-Oligocene transition and the Pliocene warm period have provided critical insights into future climate scenarios. Ramstein’s achievements include leading major international modeling initiatives and receiving the prestigious Milankovitch Medal, cementing his legacy as a visionary who bridges deep-time climate history with urgent contemporary challenges.
