I'd have to look more into why the thermal inertia is greater in models with higher climate sensitivity than in models with lower climate sensitivity. (illconsidered.blogspot.ru)
The possibility of higher climate sensitivity to CO2 in the face of inevitable increases in atmospheric CO2 concentration should be considered within the framework of climate adaptation policy. (climatestate.com)
Was this due to a particularly high climate sensitivity of this model? (realclimate.org)
