These set of future climate scenario experiments were performed with the Max Planck Institute for Meteorology Earth System Model version 1.2 in coarse resolution (MPI-ESM-CR). The model includes the spectral atmospheric model ECHAM6.3 at T31 horizontal resolution (approx. 3.75°) and 31 vertical levels, the land surface vegetation model JSBACH3.2, and the primitive equation ocean model MPIOM1.6 with a nominal resolution of 3°. The model has been extended with a full methane cycle, including a simplified atmospheric chemistry, as described in Kleinen et al. (2020) and Kleinen et al. (2021).

                The model was integrated from a preindustrial state to 3050CE following the SSP scenarios SSP1-1.9, SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5 with CO2 and N2O following Meinshausen et al.(2020) until 2500, followed by an extension until 3050CE we obtained using the CLIMBER2 model, as described in Kleinen et al. (2021).
