paleoclimate, including variability in temperature and sea level

Otto-Bliesner is a paleoclimatologist who uses computer models to investigate variations in climate in Earth's past and what that tells us about potential future climate change and sea level rise. She is particularly interested in how global climate responded to natural changes in greenhouse gases and the Sun’s output that occurred tens of thousands of years ago. She has contributed to major studies showing that the Arctic has reached its warmest levels in more than 2,000 years and that that Arctic summers by 2100 may be as warm as they were nearly 130,000 years ago, when sea levels eventually rose up to 20 feet higher than today. She was a lead author for the 2007 report by the Intergovernmental Panel on Climate Change (IPCC) and shared in the 2007 Nobel Peace Prize.
