Future experiment (2106-2115) representing a climate warmer by 2.0°C than under pre-industrial conditions (1861-1880) following the AMIP design described by Taylor et al. (2012) [1].
Natural external forcing conditions are the same as those in the current decade experiment of this CERA experiment except for sea surface temperature (SST) and sea ice coverage (SIC). SST is calculated by increasing the SST used in the current decade experiment by the difference between the climatological monthly mean results computed as a weighted CMIP5 Multi Model Mean (MMM) during 2091-2100 in RCP2.6 and RCP4.5 and the results of the CMIP5 MMM during 2006-2015 in RCP8.5. The weights are chosen such that the SST corresponds to a warming of the global near-surface temperature by 2.0°C compared to pre-industrial conditions. SIC is calculated from the SST using correlations between observed SST and observed SIC in 1996-2015. The same weights are applied to the logarithms of the atmospheric CO2 concentration from RCP2.6 and RCP4.5 of the last decade of the 21st century. Other anthropogenic external forcing conditions are the same as those in the 1.5°C experiment of this CERA experiment.
The experiment includes 100 realizations contributed by the CCCma with CanAM4.
