Mass-extinction events in Earth's history

Mass-extinction events are among the most dramatic events in the history of life on Earth. We are interested in understanding their causes, in particular how climate changes relate to the observed loss in biological diversity.

End-Cretaceous extinction event – end of the dinosaurs

66 million years ago, the end-Cretaceous extinction event ended the reign of the dinosaurs. We have performed coupled climate model simulations showing severe cooling due to sulfate aerosols from the Chicxulub asteroid impact at that time, see the animation below.
