Kenya: «A decrease in the annual precipitation on the order of 150 mm in the last quarter of the 19th century, followed by a secular air temperature rise of a few tenths of a degree centigrade during the first half of the 20th century, together with associated albedo and cloudiness variation, constitute the most likely cause of the Lewis Glacier wastage during the last 100 years.»
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?).
However, higher temperatures do cause an increased chance of heavy precipitation events, and it is likely that the flooding in some of this year's U.S. flooding disasters were significantly enhanced by the presence of more water vapor in the air due to global warming.
The way I think about is that for precipitation there is a shift in distribution caused by increased water vapor.

the attribution of a specific heavy precipitation event to human - caused GHG's is not an extra development in science that is needed to add to the burden of proof regarding the human influence on climate already provided by the current scientific evidence.»
We propose that the recent disproportionate rise and fall in CO2 growth rate were caused mainly by interannual variations in global air temperature (which altered both the terrestrial biospheric and the oceanic carbon sinks), and possibly also by precipitation.
Also part of the explanation is the claim that more humid air results in more precipitation, but again I'm unclear on why warmer air can cause more water to be evaporated, but warmer air does not by the same mechanism prevent the same water from condensing.
These facts help explain why, in spite of the Earth's air temperature increasing to a level that the IPCC claims is unprecedented in the the past millennium or more, a recent study by Randall et al.
