We here present montly sea surface temperatures from a large ensemble of 30 ensemble members of the GFDL-ESM2M. These simulations were performed at the University of Bern and span the time from 1861 to 2100. Until 2005, the model was forced with CMIP5 historical forcing datasets. From 2006 onwards, the model was forced with forcing data from the high-emission scenario RCP8.5.
