text: The SSTs and SICs were taken from a subset of the CMIP5 transient projections performed with 
  the RCP8.5 scenario from 1979 to 2100—the CMIP5 members were selected as representative of a 
  range of outcomes for future climate change, including high and low climate sensitivity, different 
  biases in baseline precipitation climatology, and different global patterns of precipitation change. 
  Speciﬁc levels of global warming such as 1.5°C or 2°C were deﬁned on the basis of the global 
  mean temperature in the original CMIP5 projections. The time of reaching a speciﬁc level of global 
  warming, therefore, varied between ensemble members. The CMIP5 SSTs were not bias-corrected, 
  which means that the results here may be sensitive to systematic errors arising from biases in the 
  present-day SST patterns. 
  
  Atmospheric greenhouse gas concentrations were prescribed from the standard RCP8.5 
  concentration scenario. Aerosol concentrations were calculated within the model, with aerosol 
  emissions prescribed again from the standard RCP8.5 scenario. This means that the greenhouse 
  gas and aerosol concentrations, and hence radiative forcing, were the same in all ensemble
