A comparison of CMIP5 Climate Models with HadCRUT4.6

Overview: Figure 1. shows a comparison of the latest HadCRUT4.6 temperatures with CMIP5 models for Representative Concentration Pathways (RCPs). The temperature data lies significantly below all RCPs, which themselves only diverge after ~2025. Modern Climate models originate from Global Circulation … Continue reading

How to normalise temperature anomalies

Update 2/7/17: I used the wrong GISS data (land only) in the comparison as pointed out by @cce! Agreement now is reasonably good for all temperature series. This is my crib sheet for comparing temperature anomalies across ground and satellite … Continue reading
