It doesn’t fully stop it — we still end up with ocean acidification and an altered pole-to-equator temperature gradient, with significant impacts on rainfall patterns.
With his version yes, but i personally think it would be more efficient to “just” deploy gigantic reflecting satellites that block the sun partially. This would be with way less risks, although higher initial investment it would probably be cheaper in the long run as well.
Spraying particles in large scale into our atmosphere isn’t a good idea. Also because regulating the density of them is way harder than to send a signal to a satellite to do something differently.
We can’t actually do that though, let alone keep it functional for the hundreds of thousands of years the earth will remain warmed by today’s CO2 emissions
We only need to keep it working for at most 200 years until we switched to carbon neutral and started reverting it.
And actually satellites are pretty easy to maintain, especially outside our cloud of space junk. There is no rust and nothing that would break it, it however would need shielding against the EMPs our sun bombards us with from time to time.
It would probably be necessary to build them in space, as such large structures can’t be shot into space directly. But we do have the technology necessary. We just need to start doing it.
Its just one step of many.
This is a satellite with a surface area far larger than anything else people have ever done, in a location where you need to use energy to stay there. It’s not going to be some simple launch-and-forget thing.
And it the need won’t be done in 200 years. CO2 concentrations will remain elevated a lot longer than that.
I said we have the technologies to do that and not that it’s easy. Also nobody said it has to be one fucking gigantic one, many “small” ones would do the same. And yes, i said we have to also get to a negative carbon output, within about 200 years that is possible. Its however way less problematic than to put gigantic amounts of rare chemicals (or pounders) into the air, wich would also cause problems with many idiots.
Many small ones implies a huge and ongoing launch schedule.
And no, if we do this, we’re not going to stop burning fossil fuels, or remove significant amounts of carbon — schemes like this mostly serve as propaganda for the fossil fuels industry to create continued permission to extract and burn.
