Why is this downvoted when the oceans warmed up nearly an entire degree after we stopped dumping sulfur into them? It is very likely that 2024 will be the hottest summer in two thousand years.
China is responsible for 70% of new coal power plant construction, meanwhile greenhouse gas output in the US (whether measured per capital, against income, against gdp, or against fuel consumption) has been dropping for almost 30 years. The ai hype could help if it means increasing automation, as compute is cheaper than commute.
> The ai hype could help if it means increasing automation, as compute is cheaper than commute.
Don't compare AI with commute. Compare AI with (human) remote work. AI will never be cheaper than remote work and AI can't replace any work that can't be remote work.
Fun fact: It could have been cooler than the hottest summer in your region in your lifetime, while also being the hottest summer, globally, in two thousand years. And at the same time, too! Isn't that neat!? :D
But economy, china, developing nations, my personal right to consumption, factor x is making this metric seem worse than it should be, another political thing is more important, technological solution Y will save us, technological solution Z won't help or has flaws... endless list of arguments that derail discussion and end up in effective inaction.
Humanity's capacity to handle an slow creeping existential threat appears to be very bad. Especially when preventing it requires simply stopping / doing less some of the things we are doing.
Apparently the production of greenhouse gasses has gone up in past years regardless of the negotiations aimed at reducing them.
I suspect geoengineering is where this will end up when things start to get really bad.
Question, what are the most viable / cost effective / low risk geoengineering tools?
> Question, what are the most viable / cost effective / low risk geoengineering tools?
Inject sulphur dioxide into the stratosphere. This can be done by adding it to airplane fuel. We have a good idea of the consequences, as ships did the ~same thing (less effectively) until recently—they're now filtering it into the oceans instead.
After we stopped dumping sulfur into the oceans the average temperature went up nearly an entire degree![1]
This will heavily affect the size of cyclones and other weather related disasters (not just heatwaves). 2024 might finally make people realize that the end is near once parts of the world in developed countries start to be slowly wiped off the map due to non stop natural disaster events.
One thing that seems obvious, but hasn't been repeated enough IMHO is that injecting more energy (heat) into a chaotic system (climate), won't simply make the average energy (temperature) higher BUT will also proportionally strenghten the chaotic fluctuations (disasters).
interesting you bring developed countries and not developing countries into the picture here first. Is it because such large scale disasters like the cyclones you mention tend to hit US more than any developing nations?
I ask because I hypothesize that the impact of these raising temperatures will be seen more widely and adversely in parts of developing countries given their population density and inability to address the same.
Well the non developed countries have suffered from these for the better part of few decades and nobody cares. My reasoning is that this happening to a developed nation would be significantly more widespread as this requires global action.
Not to mention that non developed nations tend to have other issues they're trying to solve and climate change is not even on their list (except for very few).
I struggle to see how even the worst predicted outcomes of climate change are an existential threat to the human species or our civilization. In the worst case a few billion people die or are displaced. Our species will carry on.
Losing the means of food production in the most fertile parts of the world would pretty much wipe out more than "a few billion people". It's likely that we'd lose the means to support even a billion human lives and would have to redirect our efforts into survival rather than progression setting us back hundreds of years.
edit: not to mention everyone going into war with each other for securing the small amount of places that are able to produce food.
New fertile areas will become available, Siberia and northern Canada for instance. Do you have a serious scientific source that projects the loss of agricultural capacity to the degree you're suggesting?
The land itself has to be fertile that's why the moon-belt is called like that and is currently where most of the wheat (in europe at least) is being produced. This process happened over thousands of years and is not easy to 'move' or 'prepare' land like that.
New regions would struggle to cultivate new land without fertilizers and the current fertilizer sector would struggle to operate (current sector is built around the availability of ammonia as far as I'm aware).
Your best bets would yes: Siberia, Canada. But it would take maybe few millennia before that land could be used for agriculture and it would effectively become the new oil of the world sparking a new wave of conflicts as I mentioned before.
Our current food supply could be destroyed in decades not millennia given enough heatwaves and other natural events.
I don't think so, civilization has progressed basically unidirectionally for all of history. We've never gone "back to the stone age" or regressed in any meaningful capacity, despite catastrophes of various scales.
Humanity as a whole has never gone back an age. Once we learned to cultivate plants, domesticate animals, smelt iron, we've never unlearned. We'll similarly never unlearn how to build nuclear reactors or microprocessors. I'm happy to entertain such a suggestion, but I don't see a mechanism by which climate change can destroy enough people and infrastructure to create such an effect. Our knowledge is too distributed and resilient.
I understand your point, but the scale of the potential effects of climate change combined with all the societal structures in place, and the number of people required to keep that structure "fed", that allow for the knowledge to be passed down makes me feel that even one generation worth of a significantly depleted humanity (something like 10% of current, spread around the world) who are largely occupied with just ensuring enough food and shelter to survive, will see those societal structures need to be rebuilt from scratch.
A kid famously built a neutron emitter in his suburban shed in the 90s[1]. His goal was to build a breeder reactor.
I don't personally know how to do these things either. I know how to program computers, and could teach that. My point is that I am a small component of a vast, distributed system of knowledge that is very hard to destroy. It doesn't seem practical to kill every nuclear physicist and destroy every copy of every document that describes nuclear physics. I don't see how climate change could do this.
> It doesn't seem practical to kill every nuclear physicist and destroy every copy of every document that describes nuclear physics. I don't see how climate change could do this.
It's actually very simple: climate change destroys crops and then people kill each other for food. I don't expect physicists to survive. Thugs will. And thugs can't read physics books.
PS: Microprocessors and nuclear physiscs knowlegdge is not that well distributed. I expect there are only a few hundred people in the world who know how it's done and each knows a tiny piece of it. For example one knows MCU design, but knows absolutely nothing about silicon waffers manufacturing. If they don't meet - no complete complete knowledge to build a microprocessor.
It seems you're suggesting that every structure resembling a nation state will be destroyed and we'll end up in a Max Max style dystopia where books are used exclusively to start fires. This is a bit reductionist and simplistic. I'm failing to see how food shortages and displacement, even significant enough to affect a billion people, will destroy all of global civilization. There are estimated to be close to a million nuclear physics PhDs, and millions more non-PhD experts. Nuclear reactors are being constructed on every major continent. And while there is a global bottleneck for current-generation silicon, there are hobbyists who produce previous-generation microprocessors[1].
I've never disagreed that these events will be disruptive to supply chains, create shortages, stall innovation, or force us to reconstruct lost cutting-edge expertise or infrastructure. All of these seem like relatively small hiccoughs, not civilization-ending catastrophes. Recall that the Black Death, which killed nearly half of Europe, was shortly followed by the Renaissance.
In the past 6 degrees of warming was predicted. We're now down to a prediction of 4 degrees of warming; stopping at 2.5 degrees is both possible and practical.
The safest path is undo what we did, somewhat stop adding more fossil carbon to the system, and capture the excess that we added since preindustrial times, and then some extra to unwind what some positive feedback loops added by their own. It it looks hard, impractical, expensive and a lot of more ugly words, but it goes right to try to push the system to the previous stable state.
Other “solutions” try to short term deal with one perceived problem without taking into account how the whole system is changing and how our “solution” will change it even more. With very complex systems shortsighted and not holistic approaches could bring to the table far more problems, some of which we may not have a way to deal with.
Unburning (my spellcheck marks that as a misspelling which says something even on its own) all the fossil fuels that gave rise to the industrial age we now reside in is I suppose possible in theory, but it would require a nearly limitless source of energy, and even if such a breakthrough occurred, I can't help but feel that all the energy would be directed towards ever more elaborate crypto-mining setups or AI chatbots.
The half-ass solution will be to dim the sky which I suppose will buy some time; enough to see me out I hope.
Yeah, I completely agree. But.. keep in mind: the idea that we _shouldn’t_ do geoengineering.. that ship has sailed at least a couple of decades now. Yes, dimming the sky is a more direct measure than the geoengineering we did so far. But I’m not even sure it’s less predictable than our first attempt
Letting the patient worsen his health by doing nothing, try to improve things slowly in something rational but that by now it may take longer for him to survive or giving him this potential snake oil that you don't know if it will kill him in the short term?
So far climate and related things in this complex system is full of surprises, even for experts. We are finding out that something seemingly innocent that had a clear positive impact by one metric worsened a lot of other things. I don't know if I could call engineering something with so much uncertainties on the outcome.
"If you got it, a truck brought it" is a pretty common sentiment in the transport industry because it's quite true, especially in the US. The thing is, between the economy/built world we've created and the effects on the climate, we've pretty much created a no-win scenario for humanity. Sorry kids.
I've long been thinking geoengineering is the most likely way for humanity to survive this mostly unscathed.
And this scares me a lot. The technology makes nuclear weapons look like pussies. Letting 1 country control who has which weather where is unacceptable for almost any country.
We need global cooperation to the point of becoming 1 huge global superstate, or we're having all out wars between the most powerfull nations of the world, while dealing with climate change at the same time.
And that's making the assumption that no mistake is made, with a completely new technology field, and mistakes easily killing millions of people.
> Apparently the production of greenhouse gasses has gone up in past years regardless of the negotiations aimed at reducing them.
Second derivatives matter. The growth in CO2 emissions from 2013 to 2023 was like 1/4th of the growth from 2003 to 2013.
And it's now being driven by the profit motive, not by treaties that might be reneged on at any time, so there's no reason to believe the trend will stop. All that's needed is for governments to not actively screw things up. (Which I guess is a possibility in the US due to the hyper-partisan nature of their politics, but China and India are what really matter, and both stand to gain so much from cheap energy that it's hard to imagine them being willing to stop the transition just out of spite.)
Honestly, there has probably not been more cause for optimism on climate change in like three decades.
Yet the population in developed economies will fall drastically in the next 50-100 yrs. Let developing nations have their chance at improving quality of life through cheap energy like developed nations did. Mass immigration is but bandaid at maintaining population and the resulting economic demand within the existing order.
Developing economies account for a negligible percentage of global emissions at the moment. By the time they catch up, some iterations of nuclear energy research will have resulted in more efficient energy production.
You’re probably not even kidding, it’s part of a good solution. However, take a 360° look on the other aspects of this solution:
- We seek to raise every person in poverty to the average consumption level. Through charities, political programs, etc. Should we stop?
- If you don’t drive people to earn, you don’t drive people to work. And you get a dysfunctional society which consumes a lot but does not produce a lot.
- It’s the same philosophical problem as if you started to be fair towards men, then they’d stop striving. I assure you that you don’t want that.
- Would you be ok with solving climate change at the expense of other social targets? If not, congrats, you’re a leftist not a scientist.
At-least in US we are looking at average age of presidential candidates 79y, senate 65y, house 60.
50% of wealth is owned by Boomers. They control majority of wealth and policy.
Even the current generation will be long dead before they have to reckon with climate change.
Until we get a big shock event where millions die, and the death from extreme natural causes is very evident, it won’t be something most governments take seriously.
All major governments dragged their feet through 2020 regarding Covid.
The thing that truly made me realise just how fucked we are is when the Guardian sent out a survey to the scientists behind the IPCC report. About half of them responded:
> 77% of respondents believe global temperatures will reach at least 2.5C above preindustrial levels, a devastating degree of heating;
> almost half – 42% – think it will be more than 3C;
> The financial opportunity of building in this space is massive: an estimated $3-10 trillion in EBITDA will be up for grabs. Recent legislation will also significantly accelerate the existing market trends.
Yeah, I don't think these will be part of the solution. We're not going to get out of this by making more money. Trying to make more money is how we got here.
I recently read some opinions about carbon credits for example, and boy does it look like it's just a scam to take money from governments into private pockets, while at best doing greenwashing.
> We're not going to get out of this by making more money.
I absolutely think we are going to get out of this by making money.
The incentives preventing action on climate change are not moral/ethical, but economic.
Countries and individuals use fossil fuels because they are cheaper, and are unwilling to make decisions that put them in a worse position relative to others.
While de-growth naively sounds appealing, the results are horrendous – countries with approx. the same GDP that they had 20 years ago are not places you would want to move to.
You might also point to the ozone layer issue in the late 80s and argue an accord will fix our current problem, but fossil fuels are far more fundamental to our way of life than CFCs were.
Simply (and obvious) question: Of the recent climate change, how much is human-made and how much is natural?
2000 yrs ago, the world population was a fraction of what it is now. Tbere was no mass burning of fossil fuels. And yet the temps were at record highs. Do we have enough reliable data to judge the climate properly?
If it's an obvious question to you, don't you think that climate scientists who have been looking into this for going on a century might also have thought of it and perhaps written about it?
2) The Media - and its scientist (?) pundits - would ease up on the "this is absolutely 100% human-made" narrative.
3) People who have suggested that maybe it's not "absolutely 100% human-made" would not be ridiculed, marginalized, canceled, etc.
So if you can help out with any of these, it would be appreciated, sincerely.
p.s. And per the article, the climate data that was being used prior, was incomplete, unreliable, and too small a sample size. And yet how many leaders and scientists have been basing big stroke ideas on that? We can't demand The Science, and then cherry pick bullshit because it perpetuates a narrative. Or can we??
As an ignorant outsider, I just notice that the sun gets intense and someone tells me that on the news they read that the sun is having a solar storm or something. I'm guessing the fossil fuels are responsible for reducing our protection from this storm? Cause otherwise to me it looks like the sun is the deciding factor in setting heat records.
I still can't stand plastics and pollution so I still do my bit just from a cleanliness(?) point of view rather than climate change.

Civilisation is quite the fragile structure, built slowly and carefully over centuries of large scale cooperation between much of the populated world.
