Short summary
In this study, we propose an additional climate model validation procedure that assesses whether causality signals between model drivers and responses are consistent with those observed in nature. Specifically, we suggest the method of conditional dispersion as the best approach to directly measure the causality between model forcing and response. Our results show that there is a strong causal signal from the carbon dioxide series to the global temperature series.
