On Earth, atmospheric CO2 is
absorbed by precipitation --- by rain — and forms a very weak solution of carbonic acid, a very mild form of acid rain.
Not exact matches
In addition to adding mass to a glacier,
precipitation has an indirect effect on glacier mass balance
by changing the amount of sunlight the glacier
absorbs.
I was thinking instead perhaps more easily controlled polar - orbit satellites might be used, which would rotate with some fixed ratio to their orbital period, casting greater shadows at higher latitudes... or some other arrangment... for a targetted offset polar amplification of AGW especially and in particular perhaps avoiding the reduction in
precipitation that can be caused
by SW - radiation - based «GE» (although aerosols that actually
absorb some SW in the troposphere while shielding the surface would have the worst effect in that way, I'd think)... strategic distribution of solar shading has been suggested with
precipitation effects in mind, such as here... sorry, I don't have the link (I'm sure I saved it, just as Steve Fish would suggest — but where?).
Earlier I pointed out that it could / should be better to specifically block solar IR, or in particular those wavelengths
absorbed by H2O vapor, other gases and clouds, in the troposphere, rather than block all solar wavelengths indiscriminately (because selective shading could reduce the effect on convection and
precipitation — caveats about cloud and H2O distribution... etc.).
Generally speaking, greenhouse gases tend to suppress
precipitation, and an offsetting reduction in the amount of sunlight
absorbed by Earth would not restore this
precipitation.
In warm climates for example, the net IR heating at the surface (up minus down) goes to nearly zero and the maximum evaporation /
precipitation is constrained
by the
absorbed solar radiation.
