Abstract

To predict what type of Earth lies ahead of us, we scientists usually turn to complex computer simulations. But how can we test whether these models are remotely accurate? Perhaps the best solution is to turn to instances in the geological past when Earth’s climate experienced similarly rapid warming. One such event is the Palaeocene-Eocene Thermal Maximum (PETM) that occurred 56m years ago.

In our latest research, we have identified the cause of this well-known warm period. Its links to present day climate change are clear.
