(Black) global annual mean combined land and marine surface temperature anomalies from the reference period 1961–1990 given by the HadCRUT3 data (Brohan et al.
2006, Rayner et al.
2006) in K, (dashed red) CMIP3 and (solid red) CMIP5 simulated temperature for the first member of the ensemble of twentieth century simulations. The red shaded area indicates the range of values simulated by the ensemble of 10 CMIP5 simulations done with CNRM-CM5.1. The thin gray line pictures the ensemble mean. Model data are interpolated on the HadCRUT3 grid and only grid points where hadCRUT3 data are available are taken into account to calculate the global means
