What happens if you set this up and then something (like a comet or asteroid) suddenly knocks those bubbles out of L1?
I assume that Earth would heat up more rapidly than ever in human history. This would be especially bad if we keep on emitting vast quantities of greenhouse gasses in the meantime.
Seems like a misguided idea to me, and one which wouldn’t solve the root cause of our climate problems.
In a crisis the name of the game is triage: solve enough incidental problems to buy yourself time to deal with systematic issues. This proposal, ignoring whether it's suitable or not, appears to be squarely in triage territory.
I think you might be responding to something I didn't write. I was trying to draw attention to the distinction between triage and the projects that go into triage versus work that addresses issues systematically. The GP's comment correctly noted that the idea under discussion doesn't necessarily address the systematic problem at hand, which is true, but that doesn't mean that triage is not valuable. I also specifically said that the proposed bubbles in space idea may or may not be viable; it's irrelevant to the point I was making.
