America; where every dystopic idea becomes government policy. What a fucking nightmare. Is the White House not aware that the earth's atmosphere does not actually belong to America to fuck with in the first place?
Well let me know when another county is in a position to stop America from doing anything.
I can't see any possible way that this could backfire
Once again I'll mention "A Time Odyssey" series by Arthur C. Clarke and Stephen Baxter and to be exact, the second book in the series Sunstorm. In which Earth is preparing to mitigate - as much is possible, a massive solar eruption with megascale engineering projects. The major outer space idea is to reflect this eruption with a giant shield made of Fresnel lenses fully built in space and installed at Lagrange 1 point
If we're now talking about blocking sunlight from space, why not block it with solar panels? The power can be beamed back to Earth to drive carbon capture devices, along with powering AC and everything else. I wouldn't have a problem with it as long as it can be made safe. Some have said it can here on HN. Indeed even if global warming wasn't an existential threat we should be doing that to capture more low entropy energy from the sun with solar stationary panels in the same orbit as earth. Long term we could join them together with carbon nanotube cables to make a partial dyson sphere. Why should all this energy be wasted out of the solar system?
You can block sunlight with nothing more than a bunch of mylar confetti. It's easy and cheap, and requires no additional infrastructure.

It's a terrible idea, but it at least merits a formal study ruling it out, because we're rapidly reaching the point where the only remaining ideas are terrible.

We don't need special space solar panels. Terrestrial solar panels suffice. It requires some earthbound infrastructure, but it does not require any novel inventions, just money and effort.

But we're rapidly reaching the point where even a completely decarbonized economy won't suffice, and emergency measures would be needed to keep large swathes of the earth habitable. Every one of those emergency measures are stupid and dangerous. But we're busy doing stupid-and-dangerous now by pumping more CO2 into the atmosphere every year, and we may require stupid-and-dangerous ways to limit the damage.

Sure, but it's predictably sunny 24/7 in space. Electricity generation would become stupidly cheap. With that you could turn all that CO2 into all sorts of useful stuff. e.g. food or building materials or indeed rocket fuel.
I bet if you could make stupidly cheap electricity, you could sell a lot of it, but you might ask yourself why someone isn't already doing it.
Yup, I know what you mean. It's no wonder we've regressed technologically over the last 20 years with such protectionism. What happened to the disrupt capitalist mentality so praised in sillicon valley?
> White House opens the door to study blocking sun’s rays to slow global warming

For many years it was dark. And then, one day, it was suddenly light. /s

Easy, just block them at night
I thought they were saying "Boo-urns".
If nothing else this should qualify the US as rogue state.

more great leadership from the Biden team.... Maybe a few on the team snorted too much powder in the White House? A reasonably sized volcano will serve the same purpose...
Reminds me of the dystopia featured in the 2nd season of Picard: rather than solve the environmental problems, they just used technology to block out the effects.
Please let me continue with my unhealthy sedentary lifestyle and give me pharmaceuticals to keep me alive. /s
No body mentions here the end of Dinosaurs TV television ...
