The (apparent) slower rate of projected model warming for a higher absolute temperature may be related to other factors like cloud amount and geographical distribution at higher absolute humidity, or increases in convective transport (due to more atmospheric instability) at higher absolute humidity.
[Response: At the dawn of coupled modelling, errors that arose in separate developments of ocean and atmospheric models lead to significant inconsistencies between the fluxes that each component needed from the other, and the ones they were getting.
Given that the other important variables (sea surface temps, depth of the warm layer, and atmospheric moisture) are all predicted to increase, it seems hard to make the claim that tropical cyclones will be unchanged, just as it seemed unwise to claim that Lyman et al's «Recent cooling of the upper oceans» meant that climate models had fatal flaws.
