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.
