Title: What Earth’s past can tell us about our watery future

Speaker: Andrea Dutton, Professor, Department of Geoscience, University of Wisconsin-Madison

Abstract:
Human experience is shaped and sometimes forever altered by the extremes we experience in our lifetimes. Living through an era of rapid global warming brings with it new extremes that impact our lives and our livelihoods in myriad ways. One of the more visual impacts of climate change is the increased frequency of coastal flooding as sea level rises. The greatest uncertainty in projecting the tempo and rhythm of future sea-level rise is knowing how the Antarctic ice sheet will respond to sustained warming in the atmosphere and oceans. I will describe how our ongoing research using fossil coral reefs helps to inform us about the dynamics of ice sheet retreat during past warm periods and what that means for the future of coastlines around the world.
