A spatial reconstruction of the Paleocene-Eocene Thermal Maximum: Windows into a hothouse world

The Paleocene-Eocene Thermal Maximum (PETM; 55.8 Ma) is one of the best-studied hyperthermal events. Proxy data indicate large changes in temperature and hydroclimate during the PETM, but the data are sparse and not evenly distributed across Earth, which makes it challenging to infer spatial patterns of change. Here, we use paleoclimate data assimilation to combine information from isotope-enabled model simulations and temperature proxy data spanning the PETM to produce the first spatially-resolved reconstruction of PETM temperature and hydroclimate.

Dr. Jessica Tierney is an Associate Professor in the Department of Geosciences at the University of Arizona. She specializes in reconstructing past climate change, using organic geochemistry and statistical techniques. She is a Packard Foundation Fellow, an American Geophysical Union Medalist, and Fellow, and served as a lead author on the recently-released IPCC Sixth Assessment Report.
