This is what I call a “hotfix” .
Re-engineering our space program towards space manufacturing, mineral extraction, and building permanent residences in space sufficient enough to support the people that would be needed to build and maintain space-based infrastructure like a reflector would be an undertaking I’m not sure humanity currently has the drive for.
Science and futurism YouTuber Isaac Arthur is going to love this. Giant aluminum reflectors are a huge part of future space infrastructure and he is happy to point this out quite often.
I believe they’re trying to chemically blocking the sun (using sulfur dioxide) rather than physically blocking it.
It is obvious we’re not gonna fix this by changing our habits, so I’m all for a technological solution. It will have unforeseen consequences and we will deal with those, too. Humankind is nothing but adaptable.
Wasnt this the start of Highlander 2?
You must be confused. The first Highlander movie was followed up with Highlander 3. There was no Highlander 2.
So we’ve reached “bargaining”. Good to know.
We will do literally anything to avoid changing our ways huh

I was reading about how carbon capture from the air is going to be a trillion dollar industry. Just SMH. It’s so much easier to not emit than it is to recapture. But since we’ll never get China and India off of coal, I guess we have to do something.
Not emitting is not that easy. We are in a transition period at the moment. Electric vehicles are here but we don’t have all the infrastructure needed to support them. Let alone the fact that battery tech is not developing as fast as we need it to.
Right now liquid fuels still have the advantage of greater energy density. If we could move to hydrogen fuels that would be cool, and we could repurpose existing petroleum facilities.
But who knows which way the tech is going to go. The only sure thing is that we are in for a wild ride one way or the other.
It’s difficult to get China and India off coal because they’re doing most of the world’s manufacturing and some processes are currently impossible without it. But ‘we’ exported manufacturing to Asia and ‘we’ buy the products the coal is used for. ‘We’ don’t get to wriggle out of responsibility by pretending that a couple of low and middle income countries are somehow responsible for ‘our’ excessive consumption.
But since we’ll never get China and India off of coal, I guess we have to do something.
This is a bad and uninformed take.
Per person, emissions in both China and India are still substantially lower than almost all developed countries. India’s per person emissions are less than one-quarter of the global average, and roughly one-tenth of those of the US. Close to a quarter of all carbon emissions come from manufacturing products which are exported and consumed in other countries. Textiles and clothes exported from India and south Asia account for over 4% of global emissions.
Labelling India and China as the chief villains of COP26 is a convenient narrative. The financial aid which rich countries promised yet failed to deliver as part of the Paris Agreement signed in 2015 was supposed to help developing countries dump coal for cleaner sources of energy. And while the world berated India and China for weakening the Glasgow Climate Pact’s coal resolution, few questioned the fossil fuel projects being floated in developed nations, like the UK’s Cambo oilfield and the Line 3 oil pipeline between Canada and the US.And that’s without even going back to look at imperialism and its impacts on those countries, and why they’re now having to play catch up with the west (who not only did our fair share of polluting during our own industrial revolutions, but still continue to do so pretty much freely), mostly to provide for the west.
This, like the overpopulation myth, are nothing more than racist distractions created by the rich and powerful to get us to blame “others” rather than look for who is really at fault - them (Edit to clarify: and by them I mean all obscenely rich and the governments they control, faux communists included).
The vast majority of pollution is from agriculture. Are you gonna quit eating meat anytime soon?
I did, and so should everyone else that claims to want to do something about the climate catastrophe.
Artificially grown meat is quickly becoming more and more viable, it’s not like it will be impossible forever to have a steak.
Western countries are just as guilty, if not more. We contributed terribly for several hundred years, and still today net carbon use is still increasing in developed countries. It’s just not increasing quite as much as before.
Yeah historically the United States has admitted the most carbon of any country to date. Other countries are having their industrial revolutions and we are hypocrites for criticizing them.

Great the solar roadways of climate change fixes.
American arrogance at its best.
taxing the rich properly would (blasphem alert) help redistribute wealth among workers and decrease inflation, and also make the world colder, since we dont have to work as much. but i guess we would be stripped from our daily dose of uv light soon. yea who needs vitamin b3 anyway ?
The EU is also thinking about the same exact measures:
This is human hubris just like how the Holocene extinction is human hubris, we don’t need to pin things on any single national entity.
I think it’s a combination of hubris and desperation. Hubris because it could still go very wrong and serve us a frozen extinction instead of a boiling one. Desperation because those who acknowledge what’s happening know that something probably needs to be done to not only stop but reverse this but the corporations might be more likely to burn it all down protecting their interests than cooperate.
The “easy” solutions will likely lead to war and might not even help anything at this point. The promising technologies still need to be scaled up (also in a way that makes sure we don’t overshoot the cooling targets or remove so much CO2 that plants die out).
The more I think of it, the more I like this desperate idea. If it does work too well, we can always just send more rockets to move whatever it is out of the way. Which we should have built and ready to go shortly after the blocker is deployed. Preferably sitting in orbit to minimize the chances of it screwing up if desperately needed.
Hmm sunlight is also a carbon reducer since it drives photosynthesis. But desperate times…
- Reduction of fossil fuels
- Literally block out the sun
we’re fucked
The UN Environmental Program’s recent report into SRM concludes that it is not currently a realistic or wise plan.
“UNEP concurs with the panel that, at present, large-scale, or operational deployment of SRM technologies is not necessary, viable, prudent or sufficiently safe, given the limited scientific understanding and uncertainty about the potential impacts and unintended consequences,” says UNEP’s Chief Scientist Andrea Hinwood.
“The review concludes that SRM cannot replace reducing greenhouse gas emissions.”
Nonetheless, the body doesn’t rule out the method altogether, with the report concluding that their assessment of the technique “may change should climate action remain insufficient”.
