Global albedo modification happens today its just not very directed (eg. pitch black tarmac next to concrete sidewalk there is significant difference in temperature on sunny days, AC bills would be probably bit cheaper we didn't have tarmac).
Yeah I'm sure it'll be great and we will think about every single potential side effects, just like with asbestos, DDT, lead in gas, freon in fridges, &c.
We're most likely utterly fucked whatever we do unless we go back to live like pre industrial revolution humans
