Western nations reducing will DO nothing - it is too small a fraction of greenhouse emissions. The large fraction is coming form india and china. And they do not have electric everything. they don't even have running water in most places.

Your view is outdated. China is building renewable power generation at an extremely high rate, and also exporting cheap solar panels worldwide. China has a higher share of electric vehicles in cities than most of Europe and America does. It appears their emissions are now starting to go down as a result, although the economy keeps growing. India still has a long way to go, but China is doing the right things. Same ca…

China's solar industry has some growth pangs right now but will recover: https://www.reuters.com/business/world-at-work/chinas-solar-... (Aug 2025) + https://archive.is/6hCFU + (May) https://www.carbonbrief.org/chart-why-chinas-solar-boom-is-s... (June)

Most individual and collective consumption driving polluting production is overwhelmingly traditional western/first-world economies, though China is catching up.

I'm interested in AMOC and other aspects of the problem, and this recent video by RealLifeLore was very informative for me, unlike other;s like this OP article and the like. I definitely recommend it if previously you saw only two extreme points of view about AMOC. Basically the current is weakening, yes, but it's shutdown will happen neither soon nor unexpected. In fact there are several ocean wide monitoring stations which don't rely on a guess work that much and there is a clear data trend about AMOC power and shutdown requirements.

If you really want to save time on watching the video, stations began monitoring in 2004 and in 20 years since the AMOC current calculated "bandwidth" dropped from 18 points to 16 points and physicists estimate that the drop is about 1 point per decade, and that AMOC will begin shutdown phase only after dropping to 6 points or less. In about 100 years if the trend holds. Even assuming gigantic errors or extreme climate change acceleration , it still won't decrease 100 year time by x10-x20 times less to make it happen in one decade.

So in short, it's all bad and the trend is always bad to worse, just like the real emissions (unlike estimated PR "emissions" which are usually discussed by politicians). But AMOC specifically almost certainly won't stop in our lifetime. Our kids, though, won't be as lucky.

Meh who cares? Let it all burn and flood. Earth gets a fresh start, and hopefully whatever "intelligent" species evolves to be dominant in the next 5-10 million years is a better custodian. Rinse and repeat until that's the case. Heck, who knows if this is actually the 1st or 100th iteration...

From what I recall, there will be no easy energy once our civ dies out. Whichever civilization rises after us, it will face a limit to what heights it can reach.

Part of why it'd be better to have a reset back to the beginning of evolution, so everything can happen again over all those years, and also so there are 0 traces of "tech" or trash from the past ~400,000 years to present to corrupt them. Although there being no easy energy would trigger innovations as well that'd blow all we've done out of the water, with the historical knowledge of why their predecessors became extinct and so aim for a better path to avoid that fate.

>This whole comment rests on a very big assumption that these rates will never recover. J The opposite, actually. Your assumption is that the rates bounce up and down, mostly because you don't want to believe there's a problem. The rates are transmissible, older generations to the younger. No one growing up in a world where people have few or just one child will say to themselves "hey, you know what, I want 10 kids w…

> The rates are transmissible, older generations to the younger. No one growing up in a world where people have few or just one child will say to themselves "hey, you know what, I want 10 kids when I'm an adult!"... but that's what would have to happen. And yet this exact thing happened, in reverse, everywhere in the world as certain social conditions were met. So it's not just not impossible, it's by far the likelie…

>And yet this exact thing happened, in reverse, everywhere in the world as certain social conditions were met.

No. It's never happened in the history of the human species. It's unprecedented. When human population dropped, it recovered... but only because the fertility rate was still high. Fertility rate isn't population... a sub-replacement fertility rate is literally and exactly "this population no longer grows at all".

You're gibbering nonsense right now, and somehow it sounds intelligent to you.

>This is wildly wrong. Children of 16 years should NEVER reproduce, it's an awful thing that this happened for so long of human history

It's non-ideal. Awful? Dunno. But they can, it's documented fact, and a mere 20 years after that it becomes functionally impossible at scale. That's the window of reproduction, but I guess it's easy to try to change the subject because if people start thinking about icky teenage pregnancies then they can stop thinking about their looming extinction.

>a shameful reality that will hopefully never happen again

I can promise that it will soon never happen again, because your entire species will become extinct in just a couple centuries. Your perfect utopia is coming, and more quickly than you might have hoped.

>And as health has increased, women have become able to reproduce (with some medical aid) well into their 40s

No. They've become able to in exceptional circumstances. This isn't the same thing as "able to reproduce". For it to matter, it would have to be every woman capable of this, every time. This problem won't go away because 1 in 60 affluent women will have a geriatric pregnancy.

>This is absurd hyperbole for the exact reasons above.

It's not hyperbolic. Not even a little. One of us is, but it's not me. And it's bizarre that you think it is... I live among lunatics. Go back and read your horseshit... you're talking about how there's nothing wrong and everything's just fine because some women can carry babies to term at age 74.

I recently finished rewatching The Three Body Problem in which (spoilers follow) the world panics and goes into overdrive because an alien invasion is due in... 400 years. If the current climate trends continue, vast areas of the Earth may not be suitable for habitation within half that time, and we still can't seem to convince some people this is real. Granted I was a climate change skeptic myself until about 10 yea…

If we could plan and avoid/solve clear problems that are just 5-10 years out, we’d be in a much different world.

Getting anyone to look beyond the next quarter or year is almost impossible. Decades out ?

People want the products. Industry wouldn't exist, or not at this scale, without that. The easiest way to see this is air travel. The vast majority of it is unnecessary - business trips that could be a zoom call, vacations, shipping, etc. People got to every place on earth using trains and ships before air travel. Possible exceptions are medical transport and some types of products, which are tiny by comparison. So y…

No it's not on consumer choice. The US government is SUBSIDIZING gasoline when it should be taxing it at a higher rate because of the environmental side-effects. This is standard economics theory, you tax any form of an environmental damage (e.g. carbon) at the rate of what it costs to clean it up.

Gasoline is heavily taxed as well, far in excess of the subsidies it receives compared to typical consumer goods. Jet fuel itself has almost no tax net of its subsidies, however passenger aviation is also heavily taxed compared to most consumer goods. It is for sure incorrect in both cases to say that these goods are “heavily subsidized” as a way to absolve consumers of any responsibility for their ecological choices.

This whole comment rests on a very big assumption that these rates will never recover. Just because you can fit a trend line doesn’t mean the projections will pan out. It could just as easily be the case that once population starts meaningfully decreasing, the opportunity cost of children will also decrease and fertility rates will recover. This happens all the time in nature. Our population absolutely exploded over…

When will the trend recover? When civilization falls to the point that nobody can make birth control pills, if not before.

> When civilization falls to the point that nobody can make birth control pills, if not before.

This won't save us. By the time civilization can't make birth control pills, it also means we've lost advanced medical care and now maternal/infant mortality kicks in. Nearly every baby born now survives into adulthood, barring rare misfortunes. But the idea that obstetrics will still be cruising along while we can't crank out simple pharmaceuticals is nonsense.

The trend is accelerating. We'll see 0.1 fertility rates in our lifetimes, you and me, and I'm old. We'll see central Africa hit sub-replacement fertility rates in 25 years. And even then we'll still have to listen to retarded jackasses tell us how it's no big deal, population will bounce back once things clear out. Buried deep in the human psyche is some truly superhuman level of obliviousness and denial of reality, and no logic or long term observation or plain facts are a match for it.

>Below replacement would be terrifying if there were one thousand humans, The funny part is that it should terrify you whether there are 10 humans or 10 billion. At the current rates, it's over in about 12-13 generations regardless of the number you start with. That's how it works... no matter how big the starting number, it's how many generations you have left. Think of it this way? You know the dumb story they taug…

No, this should absolutely not terrify anyone, at all. The only reason it is a concern is that our economic system is built on infinite growth, which is going to fail one way or the other eventually. It's better it fail by people voluntarily having fewer kids than any of the other possible fail states. The solution is to fix the economic system, not to worry that teenagers aren't getting accidentally pregnant so much…

>The only reason it is a concern is that our economic system is built on infinite growth,

This is plainly, factually wrong. A sub-replacement fertility level isn't "the growth has stopped". It's "rapid shrinking has started, shrinking of the sort that causes even more shrinking". That's the concern.

> It's better it fail by people voluntarily having fewer kids

If they have fewer than 2.1 on average, that's not better. It's literally "you should die out and become extinct". That's what you're telling them.

>The solution is to fix the economic system

What you're pushing doesn't fix the economy, it makes it worse. When there aren't enough workers to maintain infrastructure, there will be rolling brownouts. It's food rationing because there aren't enough workers to keep agriculture going. It's "there are no more consumer goods because the factories were hollowed out"... which leads to "there is no retail and no retail jobs".

A shrinking, aging population wrecks an economy.

>Productivity is increasing all the time, and we're very likely on the verge of another huge productivity increase with LLMs and robotics.

"Robots will save us!" is juvenile fantasy. You're deluded.

>The idea that we need to constantly increase the number of humans

No one was talking about "increase the number of humans". Maybe you're just really bad at math. We're talking about "keep the number of humans steady, because shrinking locks us into a never-recovering vicious spiral of shrinking til we hit 0". Which is where we are now.

>The crazy thing is that we have basically everything we need right now. Have you travelled? This doesn't describe most of the world. Most of the world would need to increase carbon emissions to live the way you're describing. You aren't describing a zero carbon lifestyle, you're describing a lower carbon lifestyle. And we still use carbon in building the things in your scenario: the building, the car, etc. Lower car…

The idea of average individuals being the relevant actors in global carbon emissions is pure misdirection. They're not, it's systemic with industry being the main culprit and the rich being the ones who benefit from that socialization of pollution costs. The AMOC shutdown isn't merely "possible" and due "this century" either. The math of the dynamics of complex systems shows the current behavior to be signs of a phas…

This isn't true at all. If all of the global rich immediately became carbonless monks....we would cut only a portion of emissions. And continuing to emit increases global warming. Even if you estimate that the top 1% use 70% of our carbon (implausible) that still just pushes threshold back a few decades.

And if industry stopped producing with carbon billions would starve. Industry makes stuff for people. Energy is useful, we aren't just taking oil, coal and gas and burning it in factories for fun.

It’s disingenuous to imply “industrialists” are the only ones unhappy. Anyone who doesn’t want to die a stranger in their own land is also concerned.

If the concern is one that sounds horribly like eugenics, perhaps this hypothetical "people" should indeed go the way of the dodo.

An agreeable platitude, but such a people are not born, they’re made as their neighborhoods close off, their favorite restaurants and stores disappear, their children are excluded from playdates with school friends, and they’re rejected from employment in favor of one of the tribe.

Also do consider that you’ve advocated for the elimination of people holding a belief that is far more common in the world in aggregate than in the few high HDI countries
