Funded Activity Summary

Tectonic versus biological processes: What controls the long-term global carbon cycle? A major debate in Earth system analysis concerns two competing hypotheses on the driving forces behind dramatic changes in atmospheric CO2 over geological time. One hypothesis considers tectonic/geological processes to be the major driving force. The other argues that it is the competition between plants and animals that drives the long-term CO2 cycle. We propose to test these hypotheses using a novel set of global oceanic palaeo-age grids and subduction models for the last 180 million years. This will allow us to appraise key tectonic carbon cycle components such as mantle degassing, seafloor weathering and sediment subduction.
