As discussed elsewhere on this site, modeling studies indicate that the modest cooling of hemispheric or global mean temperatures during the 15th - 19th centuries (relative to the warmer temperatures of the 11th - 14th centuries) appears to have been associated with a combination of lowered solar irradiance and a particularly intense period of explosive volcanic activity.
In addition, we investigated the relationship between asymmetry in intra-hemispheric intrinsic connectivity and language hemispheric dominance, including a potential effect of handedness on this relationship, thanks to an FMRI acquisition during language production from which an hemispheric functional lateralization index for language (HFLI) and a type of hemispheric dominance for language, namely leftward, ambilateral, or rightward, were derived for each individual.
These findings suggest that asymmetry in intra-hemispheric connectivity is a variable phenotype shaped in part by hemispheric lateralization for language, but possibly also depending on other lateralized functions.

Like I say, you see a richness of behaviour in the models including in some occasions behaviour that at first sight looks not dissimilar to that highlighted in the observations by the Thompson paper and this on top of the «external control» as we called it in our 2000 paper in Science of the external forcings in a particular model which drives much of the multi-decadal hemispheric response in these models and which, in terms of the overall global warming response, is dominated by greenhouse gases.
