Abstract
As the world warms, there is a profound need to improve projections of climate change. Although the latest Earth system models offer an unprecedented number of features, fundamental uncertainties continue to cloud our view of the future. Past climates provide the only opportunity to observe how the Earth system responds to high carbon dioxide, underlining a fundamental role for paleoclimatology in constraining future climate change. In this webinar, Jessica will review the relevancy of paleoclimate information for climate prediction and discuss the prospects for emerging methodologies to further insights gained from past climates. She will show how advances in proxy methods and interpretations pave the way for the use of past climates for model evaluation.

Jessica Tierney holds a PhD in Paleoclimatology and Organic geochemistry from the Brown University. From Rhode Island she moved at the Lamont Doherty Earth Observatory (Columbia University) as a postdoctoral fellow and then at the Woods Hole Oceanographic Institution as an Assistant Scientist. She is now Associate Professor with tenure at the Department of Geosciences University of Arizona (Tucson, USA). Jessica is a climate scientist, paleoclimatologist & leaf wax isotope expert. She combines geochemical proxy and model investigation to reconstruct past climates. She started on Quaternary climates of tropical Africa, working especially on the paleoclimatic archive of lake sediments. Then she focused mainly on using paleoclimate archives to study climate sensitivity, working on the PETM and Eocene hyperthermals, on the Pliocene warm period and on the Last Glacial Maximum.
Jessica was awarded a James B. Macelwane Medal for early career scientists (American Geophysical Union) in 2014, a Pieter Schenck Award from the European Association of Organic Geochemists in 2015 and a Packard fellowship in Science and Engineering, also in 2015.
