Antarctic Ice Sheet Stability During Warm Periods: Integrating Numerical Modeling with Geologic Data

The Antarctic ice sheet is a major contributor to sea level rise, but its response to future warming is uncertain because modern and projected CO2 concentrations are unprecedented during human existence. Geologic records offer a glimpse of prospective Earth landscapes. Specifically, past warm periods provide a window into the feedbacks and instabilities that govern ice sheet dynamics under a fundamentally different climatic state. I integrate process-based ice sheet modeling, climate modeling, and remote sensing observations along with geologic data to explore the stability and behavior of the Antarctic Ice Sheet during past warm periods.
