But the regional effects can potentially contribute to a much lower global sensitivity than people would expect if they intuitively assumed that sensitivity (with «feedbacks») can't be negative. (judithcurry.com)
Such mechanisms probably only produce regional negative net «sensitivities», and while they could add up to a negative global sensitivity, they almost certainly don't (IMO). (judithcurry.com)
Note, however, that their maximum global sensitivity of 2.9 ºC lies well within the accepted range. (pik-potsdam.de)
