To improve global sea level projections by accounting for the coupling between atmosphere, ocean, ice sheets (Greenland and Antarctica), icebergs and land processes we conducted a series of fully coupled scenario simulations with the earth system model LOVECLIP. LOVECLIP is a three-dimensional coupled climate-ice-sheet model which is based on the earth system model of intermediate complexity LOVECLIM and the Penn State University Ice Sheet Model (PSUIM). In addition to a 5,000 year-long control run, 10 forcing and sensitivity experiments were performed (see below) with 10 ensemble members each. Using a doubled subsurface Southern Ocean (SSO) anomaly could result in a different climate equilibrium. So new initial conditions were created for the Re_SSP585_2xSOTA and Re_SSP585_2xSOTA_MWOFF experiments. The initial conditions were obtained by applying the doubled SSO anomaly setting, and running the model for 650 years with fixed pre-industrial CO2 concentration.
