The United Nations Environment Assembly this week considered a resolution on solar radiation modification, which refers to controversial technologies intended to mask the heating effect of greenhouse gases by reflecting some sunlight back to space.
Honestly, I can’t see that we speed up somewhere. All I read is that last year was a new high in CO2 emissions. There‘s simply no time to buy anymore. I assume Geoengineering is the only way we can somehow keep the climate reasonable. Even it comes with additional dangers. That’s how humankind keeps progressing. E.g. Anyone going to stop AI? Or even social media? No!
This doesn’t solve all the problems caused by high CO2 levels.
One example is the acidification of the oceans. Higher CO2 concentrations in the air leads to the oceans absorbing more of it, which then gets turned into carbonic acid, which is not fun for marine life.
Reflecting light is not going to solve that.
I’m not necessarily looking for a magic bullet solution. It’s more this is not really a solution at all. All it is, is just treating a symptom. And rather poorly at that.
Also, even if we did move forward with this, how are we going to increase the reflectivity? And where? The only viable option is to paint roofs white since it can significantly reduce cooling costs in the summer. But outside of that, there’s no realistic option.
There is also the fact that trying to reflect the light back into space means reflecting it through the atmosphere a second time, giving it a second opportunity to heat it even further.
And a giant space mirror is not practical either. The resources that would go towards that could have easily gone towards more effective solutions on the ground.
Significantly more effective solutions would be to reduce our reliance on cars in western countries (simply switching to EV’s is not enough); switch to greener power sources like wind, solar, and nuclear; redesigning our products to last longer and to be more repairable; etc.
If you want something a bit more direct to donate to and support, you could check out environmental programs. I, myself, donate to Mossy Earth. They focus on rewilding and re-establishing ecosystems throughout the world. They also have a Youtube channel where they post about their projects along with updates. If Mossy Earth isn’t your thing, I know there are many other groups out there with like-minded goals. Find those groups and support/join them if you can.
Well, Snowpiercer did it for sure. I’m not sure Highlander 2 counts, but it did predict a future where everyone is miserable even though the world was technically saved from climate collapse so it’s got that going for it!
The article describes several strategies to reduce albedo and each one has significant knockdown effects that could cause significant ecological problems beyond just a warning climate.
?
Albedo modification is a completely valid response to a problem partly caused by albedo decline.
That said, you should do both.
Yes, but it also poses a risk that our politicians and public will think “we solved global warming” and not move away from fossil fuels.
This is a great way to buy time, not a permanent solution.

What WOULD we do if the bar is “solves everything with one action/solution”?

I see you haven’t watched Highlander III (or was it II?).
