Climate Models compared to Hadcrut4

Estimates of future climate change are based on the mean ‘projection’ across an ensemble of models. This is based on an assumption that each model is equally likely, but is that really true?  Surely it is far more likely that just one of the models … Continue reading

Global Warming for US & Canada ?

  The above animation shows decadel averaged temperatures for Norh America as calculated by the GISS-E2-R1_r1i1p2 model for RCP8.5 emissions scenario. GISS-E2 is my favoured model because it best reproduces a fit I made a year ago to HADCRUT4 (see … Continue reading

Future warming in Europe?

The following animation shows the 23 decadel averaged temperature from 1861 to 2100 based surface temperatures calculated by CNRM-CM5 (the French GCM) using the RCP8.5 emissions scenario. CNRM-C5 has an average CMIP5 climate sensitivity and predicts a net warming of ~4C … Continue reading
