This makes one of the biggest threats to humanity's survival being buggy software. If a software glitch from one side or the other suggests nuclear weapons are incoming, they will almost certainly retaliate in kind. And once the bombs are away, the other side will definitely respond, and that's pretty much gg humanity. In fact this exact thing very nearly happened in 1983. Soviet instrumentation indicated that the US had attack the USSR with multiple nuclear weapons. The technician on duty, Stanislav Petrov, [correctly] judged that what was happening was an instrumentation error, and disobeyed protocol - refusing to escalate it to his superiors who very well could have ordered retaliatory strikes.
For some context this had happened at once of the highest levels of tensions between the US and the USSR. This was in the era of the 'Star Wars program', which was to be a US missile defense shield, leading the Soviet Union to become paranoid about intentions of a preemptive nuclear strike attack. Those tensions had already led to the downing of one 747 that had inadvertently veered into Soviet territory, while carrying a US Congressman at that. Given this context it's highly probable that his superiors would have ordered the retaliation. So he's one of very few people who can be reasonably said to have saved the world.
If the president wants to launch a nuke, the only thing that stops them is their cabinet simply not relaying the order. This happened several times when Nixon got shitfaced.
Like nearly everything in american government, this is just a "norm". The only thing preventing an insane american president from doing pretty much anything, at least for a while, is "norms" and customs. Nixon wanted to nuke pretty much all of Vietnam pretty much all the time, and it was only his cabinet that prevented that. But there is no precedent, or legal reason, to actually force that to be the case. So what happens if you then get a president who has surrounded themselves with a cabinet that explicitly thinks Nixon was right, that Nixon had the right to burgle the Watergate hotel because the president should be able to do anything (this is a real faction in US politics right now) and have openly put together a plan to fire damn near everyone on day one and replace them with explicit yes men?
As for Nixon, he was literally playing the madman as part of a strategic goal [2] (arguably the exact same thing North Korea is doing in modern times), but privately was the one who ultimately scrapped a plan that involved nuking Vietnam. [3] A nice quote from the Madman article (from Nixon), "I call it the Madman Theory, Bob. I want the North Vietnamese to believe I've reached the point where I might do anything to stop the war. We'll just slip the word to them that, "for God's sake, you know Nixon is obsessed about communism. We can't restrain him when he's angry—and he has his hand on the nuclear button" and Ho Chi Minh himself will be in Paris in two days begging for peace."

The Project 2025 agenda targets the Pentagon as being "woke" and full of "Marxists" and will likely result in a purge of generals and officers. Anyone who has ever signed off on anything they can call a diversity program will get ousted on day 1. The vacancies will then be filled with Trump supporters.
It already started, billions of dollars in losses, with no real solution in sight.
Regarding the solution, stratospheric aerosol injection would be the most immediate and effective solution to rising temperatures. It's been estimated that current increases in CO2 have a radiative forcing effect of about 2 watts per square meter, compared to the total solar irradiance of 1361 W/m2. If CO2 levels doubled to 800 ppm then it's estimated this would have a radiative forcing effect of 6 W/m2. This scenario would require mitigation strategies like stratospheric aerosol injection to reduce solar irradiance by about 0.4%. In the context of plant growth this reduction in sunlight would be negligible given that photosynthesis is only 1 to 2% efficient. If anything we should see significantly accelerated plant growth by about 10 to 50% due to the CO2 fertilization effect at 800ppm.
About the only thing that gives me hope is SRM, but it's a half-assed solution at best. A world with 800ppm CO2 and a dimmed sun via aerosols is not the Earth that I was born to; it is probably not possible to fully understand the affects.

There is no perfect solution. One of the benefits of stratospheric aerosols is that they only stay suspended for 10 years or so, reducing the risk of long term effects. They are also an exceptionally cheap strategy, on the order of a few billion a year to cool the entire Earth. Compare that with the many trillions needed to just get to carbon neutral, while significantly reducing economic growth and living standards.
The world we were born into will not exist in any scenario. As they saying goes, you never step in the same river twice. CO2 emissions show no sign of decreasing, especially as China, India and Africa continue developing. Furthermore, we are on the cusp of AGI within the next decade or so, which will radically change reality far more than the Earth possibly getting a bit warmer in a 100 years or so. The IPCC does not even predict major cataclysm, and expects only sea level rise of a couple feet in the worst case scenario.
And then what happens? Earnest question.
It is a terrible idea which will almost certainly happen.
We don't know how bad the climate will be at 800 ppm. 300 millions years ago, during the Carboniferous era, there were vast forests and very high CO2 levels, around 1000 to 5000 ppm. If the Earth gets too hot we will simply do stratospheric aerosol injection. If climate change turns out to be overhyped, then we get the CO2 fertilization boost for free, win-win.
Regardless, the real solution is next level energy production from advanced fission, deep geothermal, and ultimately fusion power. With a vast surplus of energy we could do wildly impractical things like filter sea water for gold, and of course extract extremely diffuse gases from the atmosphere. Renewable energies are very low energy density, and more akin to farming from a physics perspective. They make sense in certain situations, but are not reliable for powering an advanced industrial civilization.
I also suspect people's intuitions are out of perspective in terms of time scales. It seems likely AGI will arise within the next 20 years. Climate change is nothing compared to the singularity and rise of superintelligence.
If that’s true, there should be global evidence of this happening already- are you aware of any publications confirming this effect?
You say accelerated growth like it’d be a good thing, but I don’t think we should wish for it or expect that to mitigate any damage… getting to the point of doubled CO2 would probably be extremely bad. If CO2 levels doubled, we’d for sure lose significant amount of our ice sheets, and some coastal cities along with it. Some of that is already happening anyway, but tripling the radiative effect will make it go much faster and much farther. As it stands, any increase in plant growth isn’t in any way making up for the rate we’re cutting down and paving over all the plants, and it’s not clear that 10 to 50% accelerated plant growth would make up for it either… even assuming that accelerated plant growth actually leads to more plants and a greater volume of oxygen cycle, and not just earlier blooms.

There is. https://www.nasa.gov/technology/carbon-dioxide-fertilization... for instance.
"From a quarter to half of Earth’s vegetated lands has shown significant greening over the last 35 years largely due to rising levels of atmospheric carbon dioxide, according to a new study published in the journal Nature Climate Change on April 25."
Interesting observation: Trillions of dollars have been spent to date on emission reduction with many incurring a consequent lowering of quality of life. Some would say this is inevitable but better to survive than the alternative. To date (as far as I can tell) there has been no discernible reduction in the rate of increase in CO2 as measured at Mauna Loa station. When will this paramount metric relate to measures taken? Any guesses?
"The beneficial impacts of carbon dioxide on plants may also be limited, said co-author Dr. Philippe Ciais, associate director of the Laboratory of Climate and Environmental Sciences, Gif-suv-Yvette, France. “Studies have shown that plants acclimatize, or adjust, to rising carbon dioxide concentration and the fertilization effect diminishes over time."
The beneficial effects of increased CO2 will also be more than counteracted by other problems as the world temperature rises, such as greater heat stress and lower soil moisture.
> Trillions of dollars have been spent to date on emission reduction with many incurring a consequent lowering of quality of life
It's cheaper to avoid the warming in the first place rather than deal with the consequences, so complaining about the cost is a false economy.

It's possible that we've reached peak CO2 emissions:

...however we need to cut them significantly.

Seems like we're moving directly and rapidly towards a real solution. Perhaps not rapidly enough, but the only way to change that is billions more in "losses"
If we EVER want to get back to today's climate, you know, "normal", it requires removing gigatons of CO2 from the air. From a pure chemistry energy of reaction standpoint, that will be enormously expensive. There is zero technology that can change the physics fact that combining CO2 with something that will sequester it will take more energy than we ever got out of it.
Petroenergy is explicitly a loan. We have to pay that back
If people cared enough to make huge sacrifices, we could absolutely do it right now. Now the technology to make it effortless, so it happens automatically without people doing anything expensive or difficult? E.g. pulling carbon from the air to make things becomes cheaper and superior to pulling oil from the ground? Indeed, we are a ways from that.

Let’s be honest here. Climate change was a completely predicable problem with known causes causes and solutions. It was detected early and alarms were raised in a timely manner. Literally nothing happened. In fact, even today, nothing happens. Why? Money. Because the billionaires would rather have us all die than not buy a tenth superyacht. (NB: Go Team Orca!)
The problem was not, and is not, science. It’s money and who has it. Now those same folks and their apologists promote quite laughable ideas like carbon capture and geoengineering. Could we have gotten cheaper lithium batteries earlier with more investment? Probably, but what did we get instead? Fracking. Literally the opposite of what was needed.
Science is not magic. Even if it was, the nature of the problem means it gets exponentially more difficult every day that passes. You mange to repeal the second law of thermodynamics and somehow got the carbon pollution industry to spend enough money to make it viable? Great! Oh, oops! The permafrost melted and now 10x more powerful methane has been released, so… yeah. Too late!
It’s just Pollyanna talk that actively harmful as it not only directs resources from mitigation and migration to wasteful handouts while simultaneously giving cover for just staying the course.
But hey. Maybe I’m just a doomer, and those Titanic passengers should have just sciences up more lifeboats instead of drown. Maybe all of this just… “needs more study”.
