<Massive simplifications ahead> You can ballpark this yourself a 288 K black body in equilibrium is radiating as much energy as it receives, at T^4. To drop that by 1C to 287K means blocking 1- ( 287^4 /288^4) or roughly 1.4% of all sunlight. As the earth’s radius 6,371 km ignoring the atmosphere, the classic sunshade at L1 idea needs a surface area of something like 1.7 million km^2. And that’s assuming we didn’t keep dumping any CO2 into the air and ignore the fact the earth isn’t in equilibrium it’s warming etc etc.
A few ideas for getting various things into the upper atmosphere have been considered but reflecting an extra 1.4% or more sunlight would be a true ly Herculean task with any of those ideas and you couldn’t stop as they all decay over time.
We already are massively stressing the biosphere: mass extinctions, mass destruction of habitat, mass disruption of migration patterns, warming, plastic pollution, invasive species.
And the suggestion is to reduce incoming photosynthetic energy by percentage points????????
I get that photosynthesis happens in a narrow band of frequencies compared to other solar radiation that would be absorbed then emitted back/trapped as IR radiation... but still, geoengineering should focus on methods that explicitly track the bound/removed CO2.
Note I do not for a second believe that schemes for sequestration by pumping CO2 deep underground won't have huge amounts of ignored/undetected leakage, especially since it is a petroleum industry scheme that already pretends massive methane leaks aren't occurring far more than is accounted for in current petrol extraction.
Since the sulfur dioxide goes away after a year or two, if it does start to cause a problem then you can simply stop emitting it. However, if you absolutely want to avoid potential impact on crops, another proposed method is to use a fleet of wind-driven ships, seeding low-lying clouds over the oceans.
As for storing CO2 underground, there is one method that might work: pumping it into basalt formations, where it turns into rock in about a year. There are several pilot projects doing this.
I'm not trying to demonize you pointing this out, but the semantics of this is interesting and typical of modern engineering, and it is in the same blind spot that economics has...
No I'm not interested in crops as all. I don't care about farm yields, profitability, market fluctuations, food supply or all.
I am concerned about the stability and long term survival of the biosphere. Yes, so that we don't go extinct, but more that that, so that we aren't living in domes in a no longer life supporting planet.
Of course, engineering (and economics) are disciplines that can only work on the basis of things they can measure. Your statement basically refers to something that is measurable: crops and crop yields.
But do we have economic or engineering measurements of the health of local and global biomes, beyond "wow they are a lot worse than they used to be"? Do we have any way of saying "this engineering project or economic policy will result in this degradation to the almost infinitely complex natures of habitats and biomes? We do not. We don't even really have good approximations.
What is disturbing is that the approximations we DO have, like species extinctions, population declines in top species, qualitative observations of ecosystems, go functionally and absolutely ignored in policy, and by economics. Engineering, which produces the only hopes of technological solutions to our problems, still is riddled with the "make it work, don't worry that much about side effects" (well, since that's all the management and budget economics allow).
I harp on engineers in this case because in my experience they are strangely conservative and republican, and by extension, anti-environment. I believe this is because every large engineering project has this stage:
"The environmental impact review"
Which is a huge blob of uncertainty, and engineers hate uncertainty. And therefore, by human nature, they hate the thing the uncertainty surrounds. And so they hate environmental reviews, and they hate the environment.
This really really really needs to change.
At this point, sadly, geoengineering may be a necessary part of protecting it. We're on the verge of positive feedbacks that could take things out of our hands, as the planet starts emitting vast amounts of greenhouse gases with no more help from us. If all we do is stop emissions, there's a good chance that we'll cross that tipping point before we're done. It's possible that we've already crossed it.
How long does it take for the carbon to affix? This I imagine is like the olivine scheme?
Any big change like this would seem to me to hint at some large effects later on. In Russia alone, the changes have the potential to be huge.
I guess it is still kind of "New Year" and people are hunkered down with COVID all over the world.
Furthermore Siberia will not be exempt from climactic instability, meaning unpredictable weather events (limited seasonal regularity) making YoY farming planning extremely difficult.
Not only that, but the thawing creates extremely unstable ground, leading to very irregular subsidence.
As long as you have money, water, sun, heat, and something better than bedrock, I wouldn't call it unrealistic.
On a longer time scale, the thaw absolutely has impacts on many things. Over time the soil WILL develop fertility, if we are around or not at that point idk.

You obviously have no idea what you are talking about.
Current atmospheric CO2 level is 400ppm which already has a measurable impact on performance on tasks (compared to 250ppm couple decades ago).
Increasing it to just 1000ppm further degrades performance. And 2500ppm makes it difficult to concentrate on anything complex.
Even slight increase in concentration could lead to drastic changes over time when you consider everybody gets a little dumber.

EDIT: kragen, I am being throttled so here is my response to your below comment:
When there is plenty arguments and scientific consensus to the contrary, and the person presents numbers obviously derived from thin air, I think it is fair to state the person does not know what they are talking about.
Toxicology is a complex topic. But it is safe to say CO2 becomes toxic way before it becomes lethal. Which is to say you see adverse effects even before the concentration reaches lethal level. It may maybe take hundreds of times before it becomes immediately lethal but it is already toxic at about current concentration or 2-5 times current concentration, depending on who you ask, and not "hundreds of times" higher.
That's why the NOAEL is set at 25000 ppm, at which point CO₂ starts to cause visual disturbances, which I think fall short of "toxicity"; it's more like a recreational drug effect. If the Earth's atmosphere reached 100 times the current level, 40000 ppm CO₂ (4%!), you still wouldn't have a CO₂ toxicity problem in humans. However, you probably wouldn't have a biosphere much longer either, and at that point toxicity to humans would be a moot point.
Also, by the way, the quality of the discussion would probably be significantly improved without you saying, "You obviously have no idea what you are talking about." Sometimes people might disagree with you because they know things you don't, for example because their information doesn't come from science popularizers, rather than because they don't know things you do. If you don't keep that in mind, you are likely to embarrass yourself frequently. Believe me, I have a lot of experience doing that.
Less sneering, please.
Amen.
It is now socially more acceptable to post obvious falsehoods than to point it out. Think about it.
This flaw in human comprehension is responsible for a lot of what’s wrong with our society.
My criticism is not about how something was said. My criticism is specifically about what was said, in that I found it irrelevant.
I’d like to learn more about the topic, but I can’t learn anything about the topic from personal judgements made about an interlocutor. It’s just noise and detracts from the argument being made.
It will take probably 100 years to get to 1000ppm.
I’m all seriousness, earth seems to find a balance when it goes through these types of events. Whether we’ll make it through the ride is to be seen.
Unfortunately, it seems oceans are loosing their ability to buffer CO2 and this may cause sharper increase in atmospheric CO2.
Keywords: Plumes; Oceanography.
The trouble with CO2 is that already the amount of it in atmosphere starts making us measurably dumber and it is only going to get worse.
1000ppm is a badly ventilated room that causes headache and poor performance on tasks. Imagine experiencing this for your entire life. Imagine ALL kids having trouble with concentration, entire Earth's population getting dumber. As if we did not have problems already...
Our atmosphere weighs ~5 quadrillion (5x10^15) tonnes. We are talking about an apparatus that can suck that amount of gas and process it to remove CO2 that is already very dilute.
"As levels of carbon dioxide rose from 550ppm to 945ppm to 1400ppm, subjects’ scores under most headings declined substantially. (Problem-solving ability also seemed to suffer as levels of volatile organic compounds rose.)"
"2,000-5,000 ppm: level associated with headaches, sleepiness, and stagnant, stale, stuffy air; poor concentration, loss of attention, increased heart rate and slight nausea may also be present. > 5,000 ppm: This indicates unusual air conditions where high levels of other gases also could be present."
"Based on preliminary analysis, the global average atmospheric carbon dioxide in 2020 was 412.5 parts per million (ppm for short), setting a new record high amount despite the economic slowdown due to the COVID-19 pandemic."
hmm
there's ambiguity on how long we have left.. but we're headed towards extinction or nearly... maybe a few million survive to rebuild..
but life as we live today is completely unsustainable...
I don't see a way that we plausibly reverse course, when nearly every government, the people running them, and the private sector leaders are all just doing an end-run to accumulate as much as they can, planet be damned. Every "climate target" gets re-evaluated and pushed back every five years, and nobody seems to be held accountable for it.
Barring moonshot tech breakthrough or militant scaling-down of consumption worldwide, how can we survive?
Try watching a french film called Demain (Tomorrow) ...plenty of immediate great solutions out there
We did need a moonshot tech breakthrough, namely scalable affordable renewable energy. But that breakthrough has already happened: both PV and wind are cheaper than fossil fuels now in much of the world, and PV definitely can scale up to replace fossil fuels, and wind probably can too. So in 8–16 years we enter an era of unprecedented energy abundance, similar to the First Industrial Revolution. There are relatively straightforward ways to use this abundant energy to capture atmospheric CO₂. I outlined one in https://news.ycombinator.com/item?id=29327736.
It's a complex adaptive system where different regions/countries have already drawn their own geologic, solar, and atmospheric straws. Just because PV and wind are pushing back fossil fuels at market rates now doesn't mean entrenched fossil-fuel-deposit-rich nations will throw up their hands, turn off the pumps/mines, and go all-renewable. If wholesale fossil remains unit-profitable to extract and burn for some purpose (say, converting into crypto--or just because 40% of the value of your oil reserves minus cost is still greater than what you have in the bank), there will be a reason to burn it.
On the other side, too, there will be people whose livelihoods come to depend on a different kind of extraction.
Yes, undoubtedly ExxonMobil and Mohammed bin Salman will try to arrest this trend, just as Peabody Coal did. They'll fight like the devil. But they can't force their customers to pay them more than those customers would pay to get the same energy, ammonia, or Bitcoins from a renewable-energy-powered source. If it costs less to replace coal with solar power than to dig it out of the ground, it will stay in the ground. And that's why Peabody went bankrupt and ExxonMobil has been losing money since 02019.
It isn't necessarily the same as the logic of nation-states sitting on finite resources that may, from some point, only fall in total value.
Or the logic of money launderers, who are perfectly willing to make terrible deals in order to convert undesirable resources into desirable ones.
I suppose that math can get very weird if countries factor in expected appreciation of crypto they plan to hold. And even weirder if they end up perceiving a geopolitical stake in maintaining a certain fraction of the global hash rate.
When I mention the logic of money-launderers, I mean something more like https://www.elliptic.co/blog/how-iran-uses-bitcoin-mining-to...
Maybe what we need is radical capitalism, but all we have the balls for is corporate nepotism?
Perhaps you need more specificity in what "take a break" means.
Where are you getting your Swiss suicide statistics from please? How are you de-coupling assisted deaths from other suicide?
"Everyone in a nursing home would be dead after a few days," this statement I don't understand, I've been in EMS's as the french speakers call them.... and beyond having a high cost, many of those old people could be adequately cared for at home...or use a helper occasionally in a much more efficient/economical manner
"No food would be planted or harvested, so even when the truckers and supermarket workers began to work again the starvation would not end" Figures say ...? 6% of imports are food and beverages..., when people have time they cook, so use of basic foodstuffs would go up, that of expensive, overly packaged foodstuffs (dissapear) one would hope, I answered this question inasmuch as pointing out food in general is cheap... Switzerland is currently sitting on a huge amount of wealth that is stuck in real estate, pressure for an appreciating CHf (on which they are using debt to counter more than 2k per Swiss person)
"no one is staffing the supermarkets, no one is driving trucks to deliver food to supermarkets, no one is farming at commercial scale" Open markets are a thing, self driving trucks too, automatic check outs ...vending machines...as for commercial farming it's gotten out of hand... I studied horticulture and personally avoid supermarket food in Switzerland, it's tastless, expensive and in many cases over packaged... come to Eastern Europe...for flavour,
If people were to have more free time, don't you think, the great outside , gardening, cooking and sharing good food would be one of their préoccupations?
A simple google search turns up
"It has one of the highest sucide rates in Europe, in 2014, 1,029 people committed non-assisted suicide (754 men, 275 women), for a rate of 12.5 per 100,000 (18.5 male, 6.6 female). Not included are 742 assisted suicides (320 men, 422 women); most of the assisted suicides concerned elderly people suffering from a terminal disease."
Tldr I understand the misgivings my "naive" statements produce, but plead for people to open their minds to other potential lifestyles that could really help combat CC...
Your fundamental error is that you think food, medical care, etc., are bought with money. In fact, they are bought with labor, natural resources ("land"), and capital goods, all three of which are necessary. Money is just a consensual hallucination, a board game people play to allocate the labor and food and so on. If nobody is laboring, there will be no production, so money can only buy things which have already been produced. Food will stop being cheap immediately if it is not being produced.
Taking the metaphor literally...
You have a family and you need shelter. You need to figure out how to survive without shelter. You need to see what you can salvage. Which means still trying to put the fire out so that some of your things or some of the materials can be salvaged so you can consider rebuilding. You need to start clearing out the rubble so that you can think about eventually rebuilding your house on that land.
Yes, it's discouraging, yes it's demoralizing. But humanity (and individual humans) has faced all sorts of extreme adversity over our history. As living creatures we have a survival instinct that requires us to continue fighting. Yes, this particular crisis is our own creation. Yes, it will damage the Earth and our specific ecosystem more than any other action we've ever done in our short time here. Yes, we might have a generation or several generations globally who will have a worse quality of life than the previous one for the first time in several hundreds of years. Yes, it's frustrating that this was caused by selfish greedy humans who will never be held accountable for it, and who will most likely have to coexist with, and collaborate on solutions when they finally decide when it's too late.
Nevertheless, we persevere, and we each do what we can to minimize the damage, to innovate solutions that may protect that what remains, and we think long-long-term.
Our ancestors frequently knew that they were a part of something much bigger and that the impact they could have had on the world or improving the lives of their children were miniscule. Yet they did so anyway. We have been brought up in a generation of boundless optimism thinking that we would all change the world for the better, while living in continuously growing prosperity. Not all of that turned out to be true. That's okay. We still keep going.
Understand, I did not start out with this point of view. I'm not an optimist by nature. I spent years being depressed and fatalist as you might be. I chose this mindset as a survival tactic. But I do believe everything I wrote.
I also think neither democracy or capitalism is well equipped to ask people to make large sacrifices for the benefit of future generations. I think we should stop talking about people making sacrifices, and put effort into engineering our way out of this problem.
Ultimately it took a external event like Covid to shake things up and show the way...ie less work, less consumerism, less flying and polluting Cruise ships... but the machine/auto industry continues to dominate, as do inefficient work practices which just serve to feed the bank accounts of the middle class....
I'm currently in Egypt living on 300$ a month, learning arabic and enjoying life... why freeze yourself/heat the planet, instead of WFH or not at all a few hundred miles south... people are dumb and the internet is generally making them dumber The Shallows: What the Internet is Doing to Our Brains, by Oliver Carr
https://en.m.wikipedia.org/wiki/Sortition#:~:text=In%20gover....
For most of history of democracy and capitalism, individuals made altruistic choices for their own future generations - not for humanity, but for their own children.
It's only during the post-war boom (and only in the countries that were undamaged by the war) did automatic prosperity become the ubiquitous expectation.
And even in that context, immigrant parents made similar sacrifices.
Just bare with it? The frequent storms, and severe weather frequenting USA in recent years are nothing special in East Asia.
1m Downpour rainfall is an annual event in much of India.
Snowstorms where you see no more than a few meters are also very survivable, and people can adapt to live with them.
Kilometers long storm surges, and multi-decade coastal errosion are also something people learned to live with.
