which would mean either increases or decreases in surface temperature, which makes Tallbloke's and others» critique that Dressler ignores the reflective effect of clouds on surface temperature glaringly obvious.

The net effect of human - generated aerosols is more complicated and regionally variable — for example, in contrast to the local warming effect of the Asian Brown Cloud, global shipping produces large amounts of cooling reflective sulphate aerosols: http://www.sciencedaily.com/releases/1999/08/990820022710.htm

It is my understanding that the uncertainties regarding climate sensitivity to a nominal 2XCO2 forcing is primarily a function of the uncertainties in (1) future atmospheric aerosol concentrations; both sulfate - type (cooling) and black carbon - type (warming), (2) feedbacks associated with aerosol effects on the properties of clouds (e.g. will cloud droplets become more reflective?)

Methane seems to be picking up a bit, but then again, given the Asian Brown Cloud, so should the negative effects of reflective aerosols.

Increased numbers of aerosols provide additional locations for droplet nucleation and, all else being equal, result in clouds with more and smaller droplets hence being more reflective to solar radiation (a cooling effect).

The ONLY greenhouse type of effect occurs as a result of the effects of clouds, especially the large and reflective type which are generally cumulous (low) clouds and to some extent cirrus and stratos, but mostly the low clouds.

They assume «positive feedbacks» from GHGs that trap heat, but understate the reflective and thus cooling effects of clouds.

Perhaps somehow the extra opacity of the atmosphere causes thick low clouds to form, having little greenhouse effect and much reflective capacity.
