"How stable is West Antarctica?"
Sarah Neuhaus
One of the major concerns for the future is being able to predict sea level rise. The main contribution to an error in sea level projections comes from uncertainty in ice loss from Antarctica. Antarctica is built up from two separate ice sheets, the East and West Antarctic Ice Sheets. In this talk, I will address the stability of the West Antarctic Ice Sheet. Recent findings indicate that it is actually more dynamic than previously thought. I will constrain the timing of catastrophic retreat and recent re-advance of the West Antarctic grounding line. Understanding how this ice sheet behaved in the past allows us to better understand how it will respond to climate forcings in the future.
