The scarey thing is that technology is so advanced that the government using it may soon actually be able to affect the climate and if, as happens with scientific and tech advances, it can be done then it will be done even before we have any idea about dealing with unforeseen results of such meddling which may well be beyond technology and science for another century, assuming the results of the meddling don't shut down civilization and sci&tech.

A barge can be built with the equipment powered by sun, wind and waves to spray the water. Such a barge could be built for under 1 million. 190 of them for 190 million.

The other 8.81 billion is to pay off the concerned activists, most, but not all, of whom can be bought off.

A side benefit to spray is that more water will evaporate into the atmosphere. If these are located upwind from deserts, there will be more humidity, and more rain on the dry areas. That will cause more vegetation to suck up more CO2.

An alternative is to shoot reflective confetti into orbit. It could be selectively located to cool the polar regions or wherever.
