What’s missing from this discussion:

Anthropogenic stratospheric aerosol injection would cool the planet, stop the melting of sea ice and land-based glaciers, slow sea level rise, and increase the terrestrial carbon sink, but produce regional drought, ozone depletion, less sunlight for solar power, and make skies less blue

There are plenty of other criticisms of SAI,[0] including the potential impacts on human health as well as smaller organisms that would be even more sensitive like insects and krill; the impacts on cloud formation patterns; disrupting seasonal weather patterns leading to widespread flooding or drought and more.

It’s important to note that even the advocates of SAI pretty universally acknowledge it as a necessary evil (even if we stopped emitting CO2 tomorrow we’d still have to take some measures like these to fight back against the runaway effects that have already begun). And those scientists that oppose it are generally of the opinion that the negative impacts would outweigh the positives. One thing both sides agree on though is that we definitely don’t know enough still

I’m sure this bullshit will have no unforseen repercussions.

I think we have to accept the fact that we’re going to have to do geoengineering if we’re to avoid complete and utter climate breakdown at this point. It’s pretty clear that there is no way we’re going to cut emissions at a rate we need to cut them at, and that means we need to start considering ways to cool down the planet to give us enough time to transition off fossils. People tend to freak out at the idea of geoengineering, but we’re already doing that right now by burning fossils.

In an ideal scenario I would be down but the incompetence of the “developed world” that has been at display since the pandemic means that I just don’t trust them to do something that would benefit the whole human population.

I’d certainly be much more comfortable with China taking charge on something like this. It’s good to know that these options exist though.

My issue is that as soon as you do any successful geoengineering the incentive to change the economic system and problems inherent to it go away. They will burn everyone in the global south and save the global north with geoengineering and call that a success while continuing with the system that made that happen.

Sure, but thing is that we’re literally at a risk of going extinct at this point. Meanwhile, western economic system is collapsing as we speak. With China becoming the dominant power in the world I have high hopes for socialism becoming the norm going forward.

I should need to remind you what happened when the Weimar system collapsed, and it did so in an environment of much stronger left opposition than currently exists across the west. Fascism is far more likely than any idea on the left, followed by ww3 waged against the enemies of the existing system. I’m really not confident in what will emerge after the nuclear hell.

It’s obviously a volatile situation, but there are many possibilities other than a nuclear holocaust as well. The west is largely deindustrialized now greatly limiting its ability to wage any sort of war against peer competitors. The internal economic situation is also becoming increasingly volatile which is more likely to result in civil unrest than any sort of a unified front against China. Even the capitalist class is largely divided on this given how many companies are now dependent on China. Personally, I choose to remain optimistic and deal with problems as they come. There are never any guarantees in life, but all we can do is try and work towards a world that we want to live in.

Humans reducing CO2 output instead of researching highly unpredictable geoengineering challenge (IMPOSSIBLE)

I’ve always expected this to be a route we would take (another study explored pouring reflective chemicals into the ocean). It’s a shame we’ll never get clean air again (I haven’t seen a smog-free sky in almost a year where I live)

Possibly worse actually. It’s still a big scientific debate and there’s plenty of scientists who are of the opinion that the disruption to seasonal weather patterns, the impacts on ecosystems, the increased ozone depletion, the effects on cloud formation pattterns, etc might end up outweighing the benefits of SAI
