The Earth’s climate between 60 and 50 million years ago was punctuated by several abrupt warming events, the largest of these being the Palaeocene–Eocene Thermal Maximum. Carbon isotope records from the Bighorn Basin, Wyoming, document these events in the terrestrial realm, and show a consistent scaling between marine and terrestrial records across the three main events.
