I really think people are sleeping on the AMOC. The first season there isn't European wine/cheese/olives because of climate change is the first season European farmers probably literally declare war on their governments, to say nothing of the fact that almost no European homes can handle this level of cold.

And for some perspective, this is only one of many other huge changes that huge populations will react violently to in the next 20-50 years. Good luck to us all.

"The first season there isn't European wine/cheese/olives because of climate change is the first season European farmers probably literally declare war on their governments,"

Unlikely. The government will be the only one who can bail them out.

jeffbee•1h ago
I am interested in your implication that European farmers would have someone other than themselves to blame for this outcome. As a whole they are at least as backwards as American farmers. They are largely deniers of climate change either as a thing altogether or as something attributable to man, or are prone to believing it helps them with longer growing seasons, and their main political activity is protesting any changes in their diesel fuel subsidies.

I guess that’s what parent meant.

But just because their your fault doesn’t hinder them to blame the government.

Who do you think will MAGA blame for the consequences of climate change?

If you look at both past and modern-day equivalents you will see that the rich do buy enough people to work as safety troops.

The reason why Putin or Kim Jong Un is not dead a long time ago is that enough of the ruling upper middle class has been made dependent on their leaders and will work to ensure the safety of said leader.

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 years ago, but right now the data seems indisputable. Even if we can't find a direct causal relationship between CO2 emissions and warming, we know the following very accurately (disclaimer: not a climate scientist): (1) amount of carbon dioxide emitted into the atmosphere per year (2) concentration of carbon dioxide in the atmosphere (3) amount of extra energy that would be theoretically retained in the atmosphere via the green house effect, due to a given increment in CO2 concentration, (4) global temperatures within the past, say 30 years. Don't we know for a fact that (1) + (2) + (3) is very well correlated with (4), and that no other potential causes correlate as well with (4), and don't current computational models demonstrate an ability to predict (4) given (3). So, exactly what is the source of skepticism?

What's that scientific saying about correlations and causations? But, yeah, let's all go back to middle ages pre-industrial economy just in case.
yoyohello13•44m ago
I’ve come to terms with the fact that there is no stopping human consumption. It is simply not possible to get enough people to reduce to make an impact. The failure of the environment movements over the last 60 years are proof. The only way is ‘up and out’ developing clean, cheap methods of energy generation and lobbying to get that infrastructure built out as quickly as possible. At this point, investing more in Fossil fuels is a joke and anyone claiming “coal” or whatever is the future is simply a conman or a clown.

clort•31m ago
Well its funny. I remember reading years ago that the big problems in Europe would start when the Greenland glaciers started melting, adding significant cold water to the Labrador Current, and pushing the AMOC to the south. Never mind the sea level rise, the temperature in Europe would drop significantly.

Now, looking at the image in the article, there is a massive cold blob right there where the Labrador Current joins the Atlantic, but no mention of the theories that I've read about years ago, just that it is mysterious

snovv_crash•28m ago
Europe might have a hiccup until warming becomes more widespread and it goes back to 'normal'. The question is how long until Texas and Florida become uninhabitable because the heat isn't being shunted out to Europe, on top of the additional heat from global warming.
metalman•23m ago
Any talk of the various climactic theorys is very³ very³ likely to be wrong³.These systems are huge, interconected, and NOT UNDERSTOOD. What we do have is some data that strongly suggests that the climate is changing, possibly at an unprecidented rate.Right now. Record territory in fact.

I don't know if it's too late to stop the worst case scenarios of global warming yet or if there's still time, but it doesn't seem to be happening anyway. The world can't deal with something that requires global concentrated efforts.

However, I do think we have time to prepare for the worst case scenarios, and individual countries and states can do that efficiently on their own.

Improve evacuation routines in floodable areas, build greenhouses to deal with cold snaps, ensure there are air conditioned buildings to deal with heatwaves, have distributed local production of electricity, keep strategic food reserves stocked, and so on.

I don't see any point in blaming individuals and small businesses when wealthy investors and politicians aren't even pretending not to be giddy about all the new trade routes that open as sea ice melts.

Nobody should ever adopt sustainable practices from which you only benefit when everybody else does, in which case a minority of people who didn't adopt sustainable practices also benefit. That's just bad economics.

And then there's all the wealthy hypocrites who criticize the middle class while they make weekly flights with private jets. And dont forget the coal powered data centers, I wouldn't be surprised if there's some hypocrisy there from the epstein class too.

i get the sense that its probably overblown, sicne we've only got a couple years worth of measured data on it.

we're jumping to a catastrophe when it might just ring, and whatever the environmentalists who prioritize it qant to do about it might change something that doesnt need changing, and result in actual catastrophe when the ringing stops

mort96•31m ago
I mean the collapse of the AMOC has been a hypothesized consequence of climate change for at least many decades. I was taught about it as something scientists think could happen in primary school; it's not new (tho it was framed in terms of the gulf stream, since that's the part of it which would affect Europe). Those fears were also founded on data-based climate prediction models.

Hmm nah, I'm thinking beyond that, like a full wipe and reset back to primordial ooze stage. Although that's pretty unlikely as humans will be fully wiped out as a species before conditions get to the point of triggering a full reset, and cockroaches at least are notorious for surviving the most inhospitable conditions ever. Theoretically, a device could be built that triggers it though.

CalRobert•27m ago
The crazy thing is that we have basically everything we need right now.

You can live in a well-insulated fully electric home powered by renewable energy and have most things you need within a walk, bike, or public transport ride away, _OR_ use an electric car for the things that aren't. If you combine that with a mostly-plant based diet (or at _least_ swapping chicken for most of your beef and lamb) and have 2 kids or fewer you're... basically there.

The main reason most people can't do this is because of political choices, not technological limitations.

Granted this doesn't include luxuries like jetting halfway around the world for a 1 week holiday or living in a 4000 square foot house in the desert and driving a studio apartment an hour to work every day, but really, is that a better life?

hypfer•23m ago
> have 2 kids or fewer

This is at odds with lots of other relevant topics that go beyond just "consumption".

2 or fewer is below the replacement rate of 2.1 This _has_ already happened, but there are a lot of voices voicing a lot of reasons why they believe that that might actually be not the best situation.

tialaramex•8m ago
Below replacement would be terrifying if there were one thousand humans, it would be worrying if there were a million, and at least worthy of consideration if there were a hundred million, but there are almost ten billion simultaneous humans, we're fine.

For this to be the most effective it really needs to be deployed somewhere like India. How are they coming along with that?

dmitrygr•9m ago
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.
Tarsul•34m ago
In most countries the public "believes" in climate change. But it don't matter: People still consume much more than the planet can bear. Because they like to consume. And because they don't want to change "if no one else does it" (tragedy of the commons). So you're asking the wrong question (maybe not for a US audience, I give you that). The real question would be: How to change the behavior of a population? My best guess would be: by reforming capitalism (and/or democracy), e.g. carbon tax (imo best way would be that there's a second currency next to money for the carbon effect of every good/service). But good luck with that.

Disclaimer: For myself, I do believe in personal changes, e.g. consuming less (red meat, flights, gas etc). Not because it makes a big impact but because that's just my personal morality and it makes me feel better to do it. On a societal level it's tougher because most/many people's brains don't work like that (I think).

yoyohello13•27m ago
I’m not sure even the how to change behavior is the correct line either. I think the most successful path is likely to be: how do we make human behavior less destructive?
esafak•17m ago
A carbon tax would change behavior in short order. The challenge is introducing then maintaining it; people can always vote it out. I think left-leaning jurisdictions should definitely give it a try.
jackyinger•29m ago
The skepticism is from people who are making money emitting CO2 and don’t want to stop making money in the same old way. It is well documented that oil companies have been sewing skepticism for decades, go figure.

anonym29•28m ago
>So, exactly what is the source of skepticism?

We should define climate skepticism, to avoid indicting a strawman. I'd start with my definition, as someone with unorthodox views on climate that often place me at odds with progressives.

It may be easier to start with the elements we agree on. Is the climate changing? Yes, obviously, visibly, measurably. Do human activities, including burning of coal and hydrocarbons, likely have a causal, contributory impact? Absolutely. Is the adoption of cleaner sources of energy: solar, hydro, geothermal, wind, nuclear, as well as investment in transmission and storage upgrades, a good thing? Unquestionably. Is climate change causing a growth in a class of threat to human life and prosperity (e.g. heat deaths, coastal flooding, extreme weather events, etc.)? Of course.

As for the areas where I diverge from progressives: Do I expect any amount of reduction in human activity, including reduction of coal and hydrocarbon combustion, reduction of overall energy usage, reduction of living standards and growth targets, to make any difference in the magnitude of the coming climate change at all in the long run? No.

The earth has both heated and cooled by orders of magnitude more than worst-case projections before humans started burning hydrocarbons.

Earth's climate is changing, yes, but historically, over the last 500 million years, the global average temperature has been as low as ~11° C at times; as high as ~34°C at others. You're reading that correctly: strictly natural processes that predate humanity itself have repeatedly changed the global averge temperature by as much as ~23°C. Ice ages occurred with zero human impact, just as the Cretaceous Thermal Maximum and global atmospheric CO2 levels exceeding 1000ppm occurred with zero human impact.

If you were to measure the full range of earth's climate variation over the history of the earth, and attempt to assign and attribute causality to all sources of that climate variation, you'd find that both the presence of all of humanity and the sum impact of all of human activity is an insignificant footnote. If this duration were a football field, humanity itself would be the last centimeter of grass in the distance of that football field; the period in which we've been measuring the climate is a thin slice of a single blade of grass.

The potential and capacity of natural processes to raise global average temperatures by 23° C has always been present, and nothing we can do will eliminate that potential and capacity.

The focus of human climate concern, accordingly, should be preservation of human life and wealth through adaptation to a changing climate, not futile efforts to prevent change itself, or an irrational alarmism that seeks to instill a widespread sense of anxiety over a process that cannot (and never could be) stopped, and for which the sum of humanity is not responsible for.

Build AC in Seattle. Set up better floodgates in New York City. Winterize the grid in Texas. Fix building codes to make houses more safe from hurricanes in Florida, and develop better solutions to stop the destruction of homes from wildfires in Colorado.

And yeah, do invest in alternative sources and production of energy. Energy is good. Energy is prosperity - it's causally linked to GDP, it's a direct requirement for quality of life / comfort / happiness. We need renewable energy. We need dispatchable energy. We need zero-emissions energy. We need energy that works at night, when it's cloudy, when we run out of oil, and when the wind's not blowing. We need better storage, better transmission. More energy, more sources, and lower costs for all of humanity.

We can't stop the world from changing, and trying to is foolish; we should accept that it is changing whether we try to prevent that or not, and focus on protecting and improving quality of life for all of humanity in the face of this always-changing environment on this little blue dot instead.

This right here, it should be a Manhattan Project level of urgency, but at global "Hail Mary" level of cooperation and effort.

And the best part is that it's not like that investment is wasted -- it's foundational and will allow us to do incredible things with it.

Meanwhile the President of the United States is actively cancelling such work and doubling down on coal. Wheee!

AtlasBarfed•25m ago
Here are the positive points, relatively speaking:

- solar/wind/batteries have a fundamental economic advantage already, and there is further runway for gains in efficiency, yield, and cost reductions. All its competitors are, generally speaking, tapped out in terms of economic costs and efficiencies

- population declines are currently an inevitability of urbanization and techno-capitalism, less people, less pollution

- contrary to #2, it is likely that life extension will start to come into play for the billionaire class, and that will mean the rich elites DO need to think about the future

However, I agree, those are glimmers of hope in the grand scheme of the current system

baq•7m ago
We can't slow down burning stuff for energy, this is politically untenable.

...so the answer is to accelerate the burning, but not for the sake of burning more, but to focus on getting to true clean energy sources which will allow us to economically unwind the mess before the whole house of cards collapses, i.e. fusion + global scale solar (maybe even space solar and microwave beam down) + boatloads of batteries.
