Many fundamental evolutionary cycles on Earth - including the dispersal of supercontinents and the global carbon cycle - are driven by our planet's dynamic engine, plate tectonics. Geodynamic processes hold important implications for climate science since CO2 is released from Earth’s interior into the atmosphere. In order to link plate tectonics and complex lithospheric deformation to the global carbon cycle we combine plate tectonic reconstruction with numerical carbon cycle simulation. This allows quantifying the tectonic evolution of plate boundaries as well as tectonic CO2 release rates through deep time with profound implications for long-term climate simulations.
