American Association for the Advancement of Science (AAAS) A novel approach to a question that's been widely investigated reveals more insights about the environmental forcings associated with the end-Cretaceous mass extinction, suggesting that volcanism and other biological changes imparted stress on the global carbon cycle across the Cretaceous/Paleogene (K/Pg) boundary. In addition to providing new insights into the factors that contributed to extinction, the approach could be useful in disentangling other complex perturbations in the Earth system and their associated climatic and biological impacts.
