Do we know what reducing solar irradiation will do for plant growth though? We might actually make the root cause worse if it decreases carbon fixation.
Yep, this. Same for any kind of solar shielding. Some are so fixed on controlling a single metric (Carbon/Temperature)that they may end up inadvertently influencing hundreds of other things.
When simple solutions interact with complex systems, complex problems arise. As it is said, for every problem there is a solution that is simple, easy and wrong.
