Revising all my skiing "East Coast/Ice Coast" jokes to be "More like Iceberg Coast, am I right?". Of course assumes it will still be cold enough to have ice...which is not a fact entered into evidence.... (this sucks)

36% of the US population lives reasonably close to these sinking coasts. The real estate is worth trillions. There's no way to refill the aquifers. There's no way to reverse the oncoming sea level rise. Once you scrape away the terror and doom, you're left with really basic questions: What's to become of us? How will cities adapt? Where will all the people go?

We have this dumb collective inability to recognize that shoreline changes naturally, which compounds our issues with human acceleration of change. The difference between 17th century Boston shoreline and now was pretty interesting. Humans want to see how it is now and assume it always was and always will be just like this. Makes it really hard to get buy-in to the idea that decades from now, things will Not Be Good. So we keep doing dumb things like building on barrier islands or draining aquifers or cutting shipping lanes through salt marshes and wonder why things keep changing for the worse…

combine this with the fact that sea level rise on the (northern) east coast is exacerbated by the warmer waters being um, thicker? (sea level is rising faster there due to water water being more expansive). so yeah, storm surges, flooding etc., will be worse, which is not a great look on aging infrastructure.

BlueHorse one thing at least that they don't have to worry about on the East Coast is a subduction zone. (shhh nobody tell the PNW about Cascadia Subduction Zone)

People will move inland and it will be chaotic. We should start planning for that now, and have retreat scenarios that support the people who will need new homes, using projections of future population pressures/housing needs, etc.

I mean, we can handle this, if we want to. The US is big, we have room to move people and communities inland, though it won't be as simple as "move NYC 20 miles northwest" but we don't have to just wring our hands and wait for chaos and suffering.

We could plan!

We could build more housing, accelerate working from home/robust internet so people/business could stay stable regardless of location, provide moving support via government for affected communities, even make it more positive because there's a lot of half-abandoned, dying small towns in the interior of the U.S. that might be great places to help people move to and revitalize.

We could invest more in water reuse and stop pumping out irreplaceable groundwater. We have that tech already.

We could deploy environmental scientists to talk about how to best handle our coasts; move dangerous chemicals and industrial stuff away from the water, encourage wetlands, preserve historical artifacts that need to be moved, and so on.

We can and could do a lot of things, if we want to.

Well, we'd need to do all those things. And a whole lot more. And for some reason there are a whole bunch of people out there who get mad when we do these things, and try to stop them in various ways, a lot of which have proven very effective.

So it's not just neglecting to do stuff we could be doing if we had the gumption. Let's not make light of the challenge we're facing, or the consequences should we fail to overcome it.

It's humanity trying to organize our species at an entirely unprecedented level to face an extinction event.

We don't actually know how to survive this. As this article points out, we don't even know how hard it's going to be yet; we haven't figured out all of the consequences of the changes we've made to our environment.

And for some reason the wealthy and powerful have spent the past half a century acting exactly like you'd expect them to if climate change couldn't be stopped. While getting really good at building bunkers and life support systems. And propagating a propaganda campaign that pits the people who don't believe in climate change against the people who think it can be stopped.

People want to stop climate change. A lack of want isn't the problem here.

seriously though, we should be planning now (but we are not), moving not only people but crucial and vulnerable infrastructure. it will only get more expensive the longer it's put off.

but like, what about Florida? nearly the entire population (20+ million) is going to have to move, eventually. where the hell will they go? the Mid West can only accommodate so many...

We have the same problem back home in Western Australia where too much water has been withdrawn from Perth's superficial aquifer, the Gnangara Mound. It's devastating local wetlands as well as the local cave systems.

The solution so far has been a shift to desalination and drilling bores down to the two lower aquifers (Yaragadee's saturated layer is ~2km/1.25 miles thick, the Ogallala Aquifer in comparison is 300m/1000ft at its thickest) and drawing more from there along with pumping in treated waste water into back into the highest superficial aquifer. They aim to rebalance the whole system by 2032 to stop any further degradation but I don't see any sort of urgency about aquifer overuse here in Mass.

There are other places where this much worse. These Cities Are Sinking Into the Ground (National Geographic). Mexico City (8.8 million) is sinking over a foot a year. Jakarta (10.5 million) has an annual relative sea level rise (sea rise + subsidence) of 10 inches in some areas.

No amount of engineering can solve that, though we'll try. Indonesia plans to:

* Move the capital to a new planned city (a al Brasilia I guess)
* extend the coastal wall and build an island in Jakarta

The NG article talks about how many cities are built near river deltas, which have very compressible soil. But the root cause is pretty much emptying the aquifer. And not to get deep into the argument above, but yes resources are incredibly unfairly distributed in the world and yes there are still too many people for our ecosystem and biological equilibrium, and no that doesn't imply some sort of eugenics or black helicopters program even though some past and current ZPG people have been super racist and terrible. We have definitely overstepped our carrying capacity by a lot, especially considering that fossil fuels are required to sustain the agricultural revolution and we insist on enormous cities where the resources under and around them do not and cannot keep that many people at a reasonable living standard.

Sorry, I did go into the population derail ... the main thing is that no matter how much climate (and environmental) reporting is finally catching up and highlighting this stuff, the actual reality in the next 20-50 years is going to be messier and maybe worse than the moderately concerning FPP link. We should all keep fighting the good fight, though, as it's not all or nothing: every little thing we do to solve the problems is going to make the world some tiny percent better and reduce future suffering by some other tiny amount. It's just pretty tough for a lot of people, including me, to grapple with.

Please keep posting this stuff!

Just because it's flat doesn't mean it at risk of sea-level rise...it may be flat but it's still 200+ feet above sea level, unlike the coasts which are at sea level. There may be other reasons you dont want to move to the midwest but this is a pretty weird one to cite.

we need a planned economy, and that planned economy absolutely must prioritize keeping folks alive and keeping the world from melting over all other concerns, even though the results this planned economy must yield must more closely resemble the economies of the old eastern bloc rather than the economies of the 20th century western liberal capitalist countries.

this cannot be done via a market economy, because no matter how hard you try there’s no way to get a market to yield eastern bloc results. and so we must get rid of our “efficient” market systems and replace them with clunky inefficient hilariously dimwitted planned economies or we are all fucked.

for my part, i would give up a whole lot to live in an economy where no one has all that much, where everyone has to stand in long queues sometimes, where you’re stuck using the same damn razor for six months cause none of the stores ever have any in stock, where no one works quite so hard as most people most places work these days, where no one gets paid more than peanuts, and where the world doesn’t melt. a whole fuckin’ lot.

i started out as an lumpenproletarian ragamuffin indifferently raised by neglectful-at-best criminals (not the good type) whose candleless pumpkinheads were both beslimed on the inside with a spicy melange of undiagnosed mental illness and raw viciousness, and despite my best efforts to dodge money all my life i have somehow become a petit-bourgeois mortgage payer with a stack of money in the bank and a job that pays far too much for what it is. even so, the relative comfort i experience as someone paid dumb amounts of money to do a graeberian bullshit job is palpably far, far less than the comfort I’d experience in an economy where everyone was brokeass and no one starved and everyone had a shitty rundown apartment and no one was homeless, where no one works all that hard and no one gets paid all that much. this is because i know for a fact that there are a large number of plausible catastrophes that could knock me all the way back down to the “do street crime or starve to death” demographic at any time — most especially i am always aware that it could all go away in a split second if too many of the mental illness timebombs that my bad parents and their bad genes and their neglectful-at-best parenting planted in my brain go off at once.

so, yeah, give me the economy of east germany circa 1985. give me the economy of cuba circa right now. being relatively wealthy in a first-worldish economy feels like shit even before taking into account that all the knick-knacks and unsatisfying luxuries that this economy wants to throw at me despite my best efforts to dodge money are also precisely the things that are gearing up to sink new york forever.

give me comfortable poverty and a healthy safety net or give me death. give everyone comfortable poverty and a healthy safety net, at gunpoint if necessary, or the very efficient market will very efficiently consign us to graves under hot seawater.

If you have a slow stock market, and skyscrapers are uninhabitable (which, I mean, that's not going to happen tomorrow or ten years from now, but it's coming), (oh, and the insurance industry collapses) then our entire modern conception of wealth becomes very tricky.

I mean, we can handle this, if we want to.

I completely agree, but the "we" part is sticky, because the covid pandemic, among other things, has demonstrated that a significant chunk of the U.S. population doesn’t want there to be a “we.” Of course I mean the right-wing contingent that votes Republican; though of course not all Republicans and many who claim to be centrist, Libertarians, etc. (It’s somewhat simplistic to label them as MAGA, but it works as a shorthand.)

Or rather, MAGAs want “we” to mean a select group of people that only the approve of, and they seem to disapprove of those of the wrong color, sexual orientation, etc.

Something as “simple” as going to the doctor and getting a shot forces people to draw a line in the sand and fucking die over, so what will it mean to uproot entire cities and relocate them in new areas. I can already imagine the issues and problems and nightmares that MAGAs would cause when it’s people and neighborhoods and homeowners and careers, and just life uprooted. I would love for everyone to gain empathy for everyone else in such a situation, but some people just want to watch the world burn.

It's humanity trying to organize our species at an entirely unprecedented level to face an extinction event.

And the longer we persist in the parochial delusion that the extinction we need to be acting with the most urgency to prevent is that of H. sap specifically, the worse our descendants are going to fare.

There are eight billion of us on this planet right now and rising, which is more than its web of life can carry over the long term. We've got away with it over the few centuries it's taken this population bomb to go off by killing off indigenous peoples and drawing down irreplaceable reserves of fossil fuels and water but we can't keep on doing that for more than another few generations, either because the non-renewable resources themselves are disappearing (non-renewable, duh) or because using them has destructive side effects like climate change.

A sustainable planetary population of H. sap is going to be more like two billion than eight, because we need to leave room for everything else to thrive as well.

Whether we manage to ease our population down to that kind of figure gently via natural attrition and voluntary birth rate self-control, or whether we continue to do our best impersonation of a mouse plague and just eat everything until there's nothing left and we crash, is up to us. But whichever way we go about it, we're going to continue making other species go extinct just from the pressure our sheer numbers exert on all the resources they rely on.

If we manage to wipe ourselves out as well - and for the foreseeable future that's a pretty big if, given the staggering population base we're starting from - then we're well down at the tail end of the extinctions queue, and the most likely ultimate cause of our extinction will be the ecological impoverishment we've inflicted on ourselves by killing off everything else before getting to that point. Get it badly wrong and we could plausibly drop the carrying capacity for H. sap of this planet and any accessible Planets B from billions all the way down to millions.

It ought to be manifestly obvious that the more diversity of life we can maintain on this planet, the better all its occupants - us included - will do over the long term. And the single most consequential decision any of the present eight billion can make on an individual level with respect to that aim is whether or not to leave behind a tree of descendants of some unknowable size greater than zero.

We're the smart ones, yeah? Are we not the ones capable of understanding that every allele we possess is already more than thoroughly represented already across the existing populace? Or understanding that each one of us sharing 99% of our genetics with any randomly selected orangutan calls for a fairly radical re-imagining of what "family" and "tribe" and "us" should mean? Or deploying convenient forms of contraception that decouple our actual reproduction rate from the hardwired urges that would otherwise doom us to the boom and bust cycle seen in every top predator that has come before us?

So yeah. We need to organize ourselves not just to face the current, ongoing extinction event but to do our level best to slow it down. Make room! Make room!

And the more resources any of us currently has access too, the stronger becomes the moral imperative to hand that access on to somebody other than an immediate biological descendant. It's not like existing kids in desperate need of a stable and loving family environment are in short supply.

eviemath - "Canada is not quite the vast storehouse of untapped natural resources that some Americans seem to picture it as.)

As I age, the metaphor of Canada as "America's attic" becomes more literal.

I now own a barn. All of my people own barns, this is a hard fact. We used to build them but the residential housing stock in our community has now exhausted the option - every property has a barn on it, now.
When we bought our homestead I was especially impressed with the quality of the barn. The previous owner had done it right. The entire thing was built out of lvl headers. I postulate that the family who built the barn owned an lvl header manufacturing operation. Anyway.

I told my spouse the story of our barns. "They fill up with shit." My partner was distracted, I could tell they weren't really paying attention. "Seriously," I said, "it seems impossible, but within a few years they are floor-to-ceiling bullshit."
They dismissed my concerns. "Well, don't fill it up with shit." I nodded - but in my brain I said, "you don't understand."

I studiously avoided putting any bullshit in the barn. I was approached on three separate occasions by proximate family members who wanted to store shit in my barn. Literally yesterday I participated in a group-text chat where it was clear that I was being shamed for not storing their shit in my barn.
"It's a Jenny Lind bed, it's been in our family for ages. Your brother can't take it - he lives a thousand miles away! It would be so sad if it ended up in a dump."

So help me God I will build a moat around my barn.

Yet it haunts me. The empty space. Last week I went up into the barn. So beautiful and precious, so empty.

What I'm saying is, Canada: don't let us in. Don't do it. The pressure will become unbearable. Don't do it, there is no returning. Interminable, the shit is interminable, it flows in one direction - into the barn. Avoid this at all costs.

Yes, in order to keep the biosphere habitable we'd have to not only stop, but reverse the sixth extinction event, which is already in progress.

The idea that our species has the power to do that seems like a patriarchal delusion to me.

What if world peace doesn't suddenly break out? What if the wealthy and powerful don't change their behavior completely and learn to collaborate for the common good? What if our species can't organize at a high enough level to take on a challenge of this magnitude?

Perhaps we should be humble enough to build some contingency plans that account for these possibilities.

Like, you know, bunkers.

But in the meantime, good luck convincing most of the major religions in the world to reverse their position on human fertility.

The population of the world was two billion in 1927. It had doubled by the time I was seven in 1975, 48 years later. By the time I was 55 last year—another 48 years later—it had doubled again.

It's unlikely to double again by 2071. The rate of growth has slowed. Between 1951 and 1993 world population growth was never below 1.5% a year, and often closer to 2%. Between 1994 and 2012 it was never below 1.25%, but never above 1.5%. Since 2020 it hasn't been above 1%. That's better than past rates of growth, but it still suggests we'll hit 10 billion around the middle of the century.

What's especially striking is looking at the absolute growth figures. Every year since 1951, the world population has grown by between 43 million and 93 million people. Last year it grew by 70 million people. We've been adding a large country's worth every single year for seven decades.

Harry Harrison's Make Room! Make Room! (which flabdablet referenced above), written from the vantage point of a world of 3.4 billion in 1966, predicted a world of seven billion people by 1999. He was only a billion over, or twelve years too early, depending which way you look at it. He overestimated the rate of US growth, though. The book ended with a Times Square billboard on new year's eve announcing that the US had reached 344 million citizens. The chances are it'll reach that figure this year.

We aren't going to get back down to two billion in any kind of timely way voluntarily. To get back there by mid-century would require the global population to fall by 5% a year every year for the next 25-30 years: 400 million this year, a bit less next year, and so on down to a mere 100 million drop in the final year.

Our usual human methods of eradicating each other won't get us there. Estimated deaths in World War II were 70-85 million, 3-4% of the global population of the time, and that was over six years.

As for involuntary means, Covid won't get us there. The estimated global deaths in the pandemic have been somewhere in the region of 15-30 million (7 million confirmed to date), a fraction of a percentage point.

It would take something almost but not quite as bad as the Black Death: 50% of Europe's population dying in the space of seven years was a loss of around 10% a year. At a loss of 5% a year it would take 13-14 years to halve a population. So we need two plagues in succession, each of them half as bad as the Black Death.

Or a series of equivalent events as awful and as devastating as that.

The_Vegetables that is at the current rate of rising. if (as is likely) the rate of rising increases (say a collapse of Antarctic ice sheets, all of Greenland's land ice melting etc.,) combined with this land subsiding...then you throw in the occasional hurricane, and you will have Sandy level events becoming a regular feature.

This is not catastrophizing (I do that too, but I know the difference) this is just what is coming, and people/governments/whatnot should be preparing for it.

Much of Hawaii has higher elevation than the midwestern US.

Because all these numbers can be a little hard to visualize, I'll share my favorite link for this, NOAA's Sea Level Rise viewer. It's very easy to plug in different values, and see what areas will be affected. One suggestion to start, choose one of the optimistic projections, where we maintain 1.5 C heating and have only a 55-cm rise. (Avoid turning the scale much higher than that unless you want to be depressed the rest of the day.)

Stuff we can do on the population overload issue that's also good for people:

* make sure all women / possible baby-havers are in charge of their reproductive choices
* embrace increased but orderly immigration to countries with declining birth rates
* (the hard one) phase out capitalism/growth economies in favor of sustainable ones. Capitalism is the main reason aging populations and declining birth rates are portrayed as a "crisis". There are plenty of humans available to take care of the old people if we value that.
* Spend 100x as much on statecraft and conflict resolution for wars and conflicts as we do on weapons production rather than the other way around (made-up ratio)
* Outlaw or heavily tax industries that use water and other resources without providing a benefit to humanity as a whole (crypto, luxury goods, unnecessary duplicate goods - esp. plastic)
* Related to last one: use laws, taxes, and social pressure to decrease resource use by developed world consumers (anyone remember the very first SUVs that we mocked and were outraged by? what happened there?)
* find out how to focus on local communities over large systems without going back to the bad kind of tribalism
* ???

Maybe it's time to revisit that floating turtle before the water rises.

This time, let's not forget the unicorns.

In 2023, the crude death rate for the world was 0.755%, and the crude birth rate was 1.669%, giving net growth of 0.914%. Even if no children were born ever again, at a 0.755% decrease per year the world's population would fall by only 25% by 2062, to around 6 billion, and then would plummet to zero in the space of a decade as women age out childbirth. In the meantime, we'd all be living in Children of Men, with a particularly grim 2050+ to look forward to.

If we (a bit more than) halved the current global birthrate, like we have since the late 1980s, world population would then plateau, which on its own isn't going to relieve our current level of environmental damage. But we'll still have thirty-odd years of population growth in the meantime, unless we pick up the pace. So will we plateau at 9 billion? Ten?

Much, much more needs to change than population, and much, much faster. The only plausible ways of getting us to where we need to be by mid-century, in terms of total human impact on the planet, are drastic changes in everyone's lifestyle, horrifying plagues or natural disasters, and wars beyond all human experience. I'm guessing we'll see a bit of each, alongside attempts to carry on with business as usual for as long as possible (ten, twenty years?).

Sorry, I hadn't meant to be such a downer. It depresses me to think this through, too.

I didn't think that through. It would take five or six more decades for the population to reach zero, once the last people born this year died. But during that time, there'd be no hope of recovery (by natural means, anyway). Half a century of hopelessness in old age.

Mexico City has an elevation of 2,240 m, so sea level rise shall never concern them, but sinkholes or other uneven sinking sucks. Jakarta has an average elevation of 8 m, so subsiding plus sea level rise is hugely problematic.

It'd be nice if this impacted the US east coast fast enough to prompt some climate action, but zero chance of that.

The idea that our species has the power to do that seems like a patriarchal delusion to me.

Is the fact that we had the power, as a species, to cause the problem in the first place a patriarchal delusion?

What I'm saying is, Canada: don't let us in. Don't do it. The pressure will become unbearable. Don't do it, there is no returning. Interminable, the shit is interminable, it flows in one direction - into the barn. Avoid this at all costs.

I kind of disagree. And not just because I’m an American who emigrated to Canada ‘cause that’s where I found work. There’s a crucial difference between letting people in and letting wealth out, via exploitative resource extraction. Sharing on an equitable basis is good; and in particular, Canada is also currently dealing with some regressive xenophobia around immigration that the fascists here are trying to stir up to help them gain more political power, and that is very bad. But one can be compassionate toward members of our global community who are in need while also building and protecting robust, sustainable local economies and preserving environmental health and quality.

But my main point was that, literally, Canada doesn’t have the amount of water that some Americans seem to imagine is has. The Canadian prairies have the same seasonal drought issues as the US plains; the Western Canadian mountains and coastal region are impacted by the same seasonal snowpack issues as the US West Coast. The Canadian Maritimes have been impacted by drought and wildfires to similar levels as New England, and have the same issues around Nestle extracting “artesian” water for next to nothing to sell at a huge profit, impacting local home wells, etc. The strip of Canada along the southern border where the majority of people live isn’t that different from the northern US; the parts of Canada farther north are not snow-covered year round (for water extraction) and also have minimal snow cover (so agriculture can’t just shift north as climate changes); mining is already causing significant environmental degradation in many parts of northern Canada, and I’ve read that the Alberta tar fields have passed or will soon pass their peak oil production. It’s simply not a store of infinite natural resources, regardless of whether it’s Americans or Canadians or anyone else profiting from exploiting them.

We broke it. That doesn't mean we can fix it.

And that's what gets me. It's that kind of thought that's at the basis of the whole "of course we can fix the climate" conclusion. And it's so obviously, blindingly nonsense. Ask a toddler to fix the computer they broke, see what happens. Ask your beagle mix to put the garden back together.

I mean seriously, ask yourself how you can believe that the fact we broke the climate in any way suggests that we have the ability to fix it. You're so much smarter than that. Doesn't that make you wonder why you believe what you believe about climate change?

The saying isn't "you broke it, you fix it." It's "you broke it, you pay for it."

I think we're a young, dumb species. I don't think we know how to organize at a level that would allow us to face a challenge at this scale. I think we've done a great job with civilization so far, given that we're making it up from whole cloth with no guidance and no examples, but I think fossil fuels turned out to be a trap that we simply weren't prepared for.

So now it's survival of the species time. I hope we make it.

For what it is worth, if we hadn't found fossil fuels, we wouldn't have any trees now because we'd have burned them all.
