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
