Not if Count Binface wins the elections.

First the UK, then leadership of Europe via behind-closed-doors politics, then a gentle colonization of both the east and the west using our amazing cheese, bread that is baked rather than synthesized from fossil fuels, and 30 days of paid vacations per year. The path forward is clear.

No, excessive fossil fuel use is the cause by an immense margin. It's completely dominated by commercial shipping (boats), followed by planes. Then I think it may actually be gas from cattle before cars. Bitcoin and AI are so recent and still relative to everything else small.

I really feel like if the US really wanted to support US shipbuilding (like what the Jones act was supposed to do) it would subsidize building a fleet of nuclear shipping boats.

Lots of manufacturing projects, lots of related industries boosted, a renewed investment in nuclear engineering bringing a lot of nuclear job experience, and a way to potentially dig deeper into the backbone of global trade again.

scottLobster | an hour ago

I love the theory, but the security concerns around nuclear anything are a big deal when we're talking ships that sail around the world.

Imagine if even one of the tankers hit in the strait of Hormuz was nuclear.

vel0city | an hour ago

Would Iran be as likely to have hit one of these ships if the result was potentially a nuclear meltdown close to their shoreline? It would pretty radically change the costs to them for such an attack, wouldn't it?

Ekaros | an hour ago

If you sink nuclear ship you won't get nuclear meltdown. You have enough thermal mass to cool down anything if you are underwater. Some level of loss of nuclear material would happen. But meltdown is not something that would happen.

vel0city | an hour ago

Its not like all the ships hit by attacks in the Straight of Hormuz sank. A ship could potentially become critically damaged and become unable to operate the reactor and still be floating.

Either way, "loss of nuclear material" is the real concern isn't it, instead of just the nature of how that loss happened?

The question still stands. If a country knows they're potentially going to cause a nuclear disaster by hitting one of these ships on their shoreline, are they as likely to shoot at them?

scottLobster | 16 minutes ago

The hardliners might want to cause a nuclear incident to keep the strait closed longer.

And even among the non-hardliners mistakes are rampant in war. It's not about what they're likely to rationally do, it's about what some local, demoralized missile officer who graduated in the bottom 20% of his class does when he's cut off from command and drinking too much.

Widespread use of nuclear power for civilian merchant shipping is a non-starter. It's simply too expensive to train and pay enough qualified nuclear engineers. The US Navy barely manages this for a few dozen nuclear powered vessels with a huge budget and limited concern for cost effectiveness.

Plus there are the security concerns. Every civilian nuclear power plant has armed guards on duty around the clock. Those guards have to also be trained and paid. Many foreign countries have laws against bringing weapons into their ports.

If we want to reduce CO2 emissions from merchant ships then use nuclear or renewable power on shore to manufacture carbon neutral synthetic liquid fuel. Use that to run the ship engines.

othello | 2 hours ago

This is completely incorrect. Aviation contributes 2.5% of global emissions (but is terrible on a per capita basis, as only around 10% of the world's population travels on any given year). Global shipping accounts for 2.3% of global human-made emissions [1].

In transport emissions, passenger vehicles dominate by far (with around 12% of global GHG emissions), even more so in developed countries. Then freight by road with 7.5% of total emissions.

Maritime shipping is actually the least carbon intensive way to transport goods over long distances by at least two orders of magnitude [2].

atoav | 2 hours ago

Sure. But you have to weigh any application relative to (1) how useful it is and (2) how easy it would be to rely on a carbon-neutral alternative.

And I would argue the usefulness of bitcoin is negative from the viewpoint of a free society.

AI is to a certain degree a different story, but also there it depends what you're doing.

We live in a thin atmospheric skin around the planet, and that skin has a finite volume. If earth was the size of an apple, the atmosphere is thinner than the Apple's skin in proportion.

Pretending we can do whatever we like for infinitly long inside an finite volume is completely unhinged. The financial and political elites, who some frame as the true geniuses point to technological solutions that are always "just around the corner" for the past decades with some of them even eying to leave the planet behind entirely.

All of that while we know how to address the issue.

On the topic of thousands needlessly dead, look at the UN's suggestions:

Useless yapping about opening windows at night, protecting the vulnerable, limiting global warming to 1.5C, and not drinking caffeine.

Is any of this "Call to Action" actually actionable?

Obviously not; and it is pathetic.

What should be actioned:

- remove regulatory hurdles to AC installation

- mandate such installation in residences that otherwise reach unbearable temperatures

- make funds available to subsidize the installation or train more workers for AC installation

That would 'protect the vulnerable'.

Talking about opening windows at night or climate change does nothing, and is performative only.

user43928 | 2 hours ago

Sure, but this should be an afterthought here.

You cannot talk about thousands dying today, neglect to mention the actionable solution, and talk only about climate action which will help on a time frame of decades to centuries.

bsian | 2 hours ago

The thousands dying are just a means to an end. They don't really care about them.
I grew up in the 90s and there was a book in climate in my shelf that talked about thousands dying today, nearly three decades back. At some point we should stop pretending this is a new and surprising danger and start treating it as the risk we willingly steered ourselves into.

If you live next to a road and every other month a car crashed through your living room wall you'd probably fix the root cause after the first time it happened. If you are clever you fixed it even before it occurs. What you would not do is only deal with the damage caused month for month and pretend there is no need to address the root cause.

The reason why many pretend our only option is handing out band aids while the blade keeps spinning, is because it is hard to imagine anything else, if your salary depends on you not addressing the problem.

It feels more and more like watching a bus driver playing chicken against a solid, immovable concrete wall. It is obvious who wins, the only question is into which directions the scrap explodes most, while the driver eyes for the ejector seat. And all the kids pretend driving into the wall is the only reasonable option.

It is possible for humanity to create unsurvivable conditions in our earths atmosphere. Should we do that if there is enough profit in it? If not, where would you draw the line and how would you set/enforce the limits?

I think we can all agree that if we just stop talking about climate change, maybe it will go away.

I've been reading up on the inevitable collapse of the AMOC (the potsdam institute has a number of really good videos covering the subject).

Everyone hears 'winters will be up to 10C cooler', but few realize that this will also cause the jet stream to be more wavy, and exacerbate the number of heat waves as well.

Sad that europe's mild climate is about to get a whole lot worse...

What in that link do you think is saying it is not inevitable?

user43928 | 2 hours ago

Even if you read just the conclusion at the bottom it seems obvious that there is no consensus about a collapse being inevitable:

> Overall though, there is some common ground in recent research: evidence for AMOC weakening having begun is growing, albeit is not clear in every AMOC metric; a substantial decline is expected with current emissions, that over centuries could potentially push the AMOC to a slow ‘shutdown’ state; and there remains a real but uncertain chance that this slowdown could pass a tipping point beyond which this shutdown is locked in, even if warming is halted or even declines. Exactly how much and quickly the AMOC is weakening, and the likelihood of it reaching a tipping point, remain much more uncertain, but what we do know is enough to justify concern and action to reduce the risk of AMOC shutdown

wing-_-nuts | an hour ago

I am just repeating the 'gist' I've gotten from my research on the topic, but the risk of AMOC shutdown has gone from a low probability / high impact prediction by 2100, to 'we think there's a strong chance of hitting a tipping point by 2060'. I wish I could point you to a specific paper, but I'm going entirely off memory, and that is fallible

The % likelyhood by x date predictions have swayed back and forth as we've adjusted our predictions of which emissions path we actually wind up following.

I'd highly recommend the analysis I linked if you did not yet check it, he discusses various papers and differences in definitions.

wing-_-nuts | 33 minutes ago

Took a min to read the link, that was a surprisingly good summary.

My whole concern with the AMOC is that given it's a non-linear system, and we've seen evidence of 'fast shutdowns' in the climate record before, I fear we are sleepwalking towards an event that could have catastrophic consequences for the global south, and problems there do not stay there. People flee rather than starve.

I also worry what happens to western liberal democracy under the weight of that influx if we're already seeing populism from today's level of migration.

Erasing any datacenter ever built (and planned) would do almost nothing to stop climate change.

What we need is (global) electrification of transport and heating, CO2 free electricity and CO2 neutral concrete and steel.

Very effective ways to make this happen would be high prices on emissions, enforced on every local industry and all imports.

But too many people love their cheap fossil-based transport too much and are unwilling to make even small sacrifices to keep the climate stable; sad reality.

athrowaway3z | an hour ago

If only Al Gore warned us about AI as well! /s

Thinking these are at their current level relevant to climate change, is a level of ignorance that I'd almost put on a tin-foil hat to discuss how the fossil industry is feeding an anti-AI campaign of ignorance.

The warming is terrible and deadly, AND ALSO Europeans are negligent in not protecting themselves however they can.

The idea that Europe could slow warming by not using air-conditioning is absurd, when the emissions mostly come from elsewhere. France, in particular, gets most of its energy from nuclear power, but also makes it very hard to get climatisation.

Arodex | 2 hours ago

>Europeans are negligent in not protecting themselves however they can.

Well, if the people in charge say or think global warming isn't real, that's what you get: not "other" solutions to the "unacceptable propositions" the Green parties suggest, but no proposition at all, as there is no problem.

The current situation is a direct consequence of pure negationism from conservative parties, not a disagreement on how to deal with climate change between the Right and the Left. The Left proposed solutions you may not agree with, but the Right has been completely rejecting the reality of climate change.

BTW, how do you propose Europe protect not only people from the heat, but also forests from burning, rivers from drying up, fields from being unfit for cows and sheep, lakes from blooming with algae, nuclear plants from being shut down due to river water being too hot and seawater being full of jellyfish, etc, etc, etc? In the end, there are so many things to "adapt" that it would cost less to try to organize a global effort to lower CO2.

[H]ow do you propose Europe protect not only people from the heat, but [all these other things]?

Why does it have to be framed as all-or-nothing? I agree that using air conditioning to reduce the number of people who die from the heat does nothing to help with the problem of jellyfish, but how is that relevant, exactly?

Honest question. How could effective global climate action look?

myrmidon | an hour ago

Put a significant price on CO2 emissions (think like $300+/ton, instead of <$100), then tax every import from countries that take insufficient actions (or run a low CO2 emission price). Likewise, tax any export into countries that take no action.

Electrify everything where possible (especially transport and heating), get electricity CO2 neutral, get concrete and steel production CO2 neutral (lots of those would be an inevitable consequence of the emission pricing).

This would allow western democracies to basically fix the global situation on their own, by exerting economic pressure on developing countries (those want/need market access, like China).

It would make goods (and especially individual transport!) more expensive though (even if you re-emit the tax income), so you can be sure it's not gonna happen, because too many people are too selfish.

I will say this - air conditioning costs to establish room temperature are inversely proportional to the degree the building is insulated. If your whole country is comprised of uninsulated or barely insulated housing stock, you have a MUCH larger project than simply buying some small window units for a few hundred euro per person and then paying a few hundred euros extra per year in energy costs.
Don't they have to heat them in the winter too? That also costs more and creates more emissions without insulation.
Some of these places don't get very cold, others rely on coats, others south facing window solar gain. Very old buildings are common. I'm not claiming all of Europe is uninsulated, just a large enough portion to render heatwave safety a much bigger problem.

When I lived in a rather hot area of Spain for a year, I was shocked to find out that many apartments don't have an air conditioner. In a place where a similar heat wave happens every year, for months. A friend of mine moved there from Germany and being somewhat frugal, rented a place without and aircon. Let me just say that he didn't enjoy the summer nights one bit.

I myself had one, but I could probably rent a car for the cost of running it.

atoav | 2 hours ago

If you can't run one fifth of your nuclear plants, because the water levels are to low or the water temperatures too high in the rivers used to cool them, you may want to reconsider whether that is truly the best choice here¹

In the meantime my fathers solar roof allows him free AC cooling, because as it turns out AC generally needs most energy when the sun shines the most.

I am not arguing nuclear plants do not have benefits, I just argue that solar with storage may be a much better fit for powering ACs.

¹: https://www.euronews.com/2026/08/12/heatwave-and-jellyfish-a...

People live longer in many parts of Europe than the USA. Does that mean the USA is somehow negligent?

Excess deaths due to heat are primarily the in the elderly. The excess numbers we are seeing now are because the proportion of elderly people in France, Germany and Spain are higher than in the USA.

If the population pyramid in the EU was more similar to that of the USA the number of excess deaths would be lower. I'm not sure negligent is the correct word to use. Climate change will reduce quality of life. Because of these changes people will not live as long.

That's how excess deaths work.

Somehow, somehow, everyone’s heads are still in the sand. Desperately trying to bury them deeper. It’s like CICO denialism.

I expect this to be a deeply unpopular take here, but solutionism will fail. Magic technology will not come to save us. All of our industrial tekhne has been in the service of rolling down the stored-energy hill faster and faster. To put the genie back in the bottle, to take apart the CO2 and turn it back into hydrocarbons, we’d have to do more work than everything that was done in the last two centuries. And that’s an extremely conservative lower bound.

It’s so dire. I don’t think most people understand that everything around them is made out of petroleum. Not just your ability to travel, or your clothes. Your food is made of petroleum. Your institutions are made of petroleum. Your gender equality is made of petroleum. Your freedom is made of petroleum.

There is no putting this thing in reverse. If the AI doesn’t get us first, thermodynamics will topple all of this.

kldavis4 | an hour ago

While it is true that reversing combustion would require more energy than was released burning it, I don't think anyone reasonable is proposing it. The proposal is to redirect future energy production away from fossil extraction and into cleaner sources (solar, wind, nuclear, geothermal) which is a completely different thermodynamic problem. The constraints are things like grid storage capacity, permitting timelines, and critical mineral supply chains - not physics.

If we overcome these very real contraints, we reduce the rate of new additions to atmospheric CO2. We will still need to do the thermodynamically hard work of removing CO2 at gigaton scale, but deferring that until removal tech is more mature is the right sequencing.

Of course, this assumes that we are actually working towards the CO2 output reductions right now and really committed to CO2 removal in the near future.

I agree that it’s a little weird, insofar as people don’t talk about it, but I’m not sure it’s very woke at all. It’s in a lot of tension with conventional woke ideas.

The usual way people talk about all this is more or less idealist (as opposed to materialist): people thought hard and got better morals (or worse morals, if you have a reactionary bent). The claim I’m making is that it’s not a coincidence that egalitarian norms happened to be correlated with the falling cost of energy. It’s basically the same idea as “God created men [and women]; Sam Colt made them equal.”
