Description
Madeleine Stow and seven co-authors use rhenium isotopes in two thousand twenty-six to track an ancient warming event. The event, the Toarcian Oceanic Anoxic Event, took place in the Early Jurassic. Weathering of rock can draw down carbon dioxide, but it can also release it when carbon in rock is oxidized.
The team measured isotope values in marine sediments laid down across the event. Values fell during the warming, and their model links that fall to faster oxidation of rock carbon on land. Earth warmed by about six to seven degrees at the time. They estimate the process sent a huge amount of carbon to the oceans and air. Weathering, they conclude, can amplify warming rather than only damp it.
