Abrupt Climate Change


Overview

Over the last two decades the climate dynamics community has come to realize that climate change is often abrupt relative to climate forcing. A recently completed National Academy of Sciences study (Jonathan Overpeck was a participant/co-author) makes the case that abrupt climate change also poses a serious future threat to society, both in developed and developing countries.

An overarching goal of our research is to contribute to a better understanding of abrupt climate change, both during glacial/deglacial periods and interglacials. As with other research foci we are pursing our goal via the collection of new records, synthesis, and modeling studies.
