Sensitivity of global carbon cycle to CO2 rise

Analogous to 'climate sensitivity' one can also define a 'carbon sensitivity' that characterizes how strongly the land and ocean carbon storage changes upon a doubling of atmospheric CO2. In this bachelor thesis this carbon sensitivity shall be computed by a Gregory type method from simulation results of the CMIP ensemble (CMIP5 and/or CMIP6) using the output from the 4xCO2-experiment (CO2 is abruptly increased to four times the pre-industrial concentration). The result of this bachelor thesis will demonstrate how strongly carbon cycle dynamics differs between state-of-the art Earth system models in reaction to CO2 rise.
