Reply to comment by Sleepdprived in Controversial Proposal to Reduce Global Warming Could Threaten Ozone Regeneration by Rear-gunner

The earth receives far more sunlight than plants or animals need to survive and thrive. Reducing solar insolation by a few percent will have zero impact on life.

“Zero impact” would be false. You can’t change something like that by “a few percent” and have a 0% change.

Of course. Obviously we’d be doing it to lower temperatures and prevent climate collapse. I mean to say that it would not be harmful to life.

It would have no meaningful impact on the ability of any biosphere on Earth to function as it currently does. We get about 50% more sunlight than we need. The majority of that sunlight (and I mean the enormously overwhelming majority) is converted into ambient heat.

We know this because when the sun dims by several percent over the course of years, nothing happens on Earth, except global temperatures very slightly drop.
