Short summary
The Eocene–Oligocene climate transition (EOT) is one of the most drastic climate changes of the Cenozoic era and the final stage of the shift from ice-free to icehouse Earth. Here we present high-resolution records (geophysical, geochemical and sedimentological proxy data) of the EOT from lake deposits to detect the atmospheric expression of the EOT via the hydrological cycle. Such records provide strong constraints on climate modeling and on our comprehension of the forcing mechanisms of EOT.
