I agree that we need to plan for climate adaptation (preparing for predictable problems) and resilience (preparing for unpredictable problems), but I have a few kneejerk responses:

- Although it's looking increasingly unlikely that we can avert climate disaster, we can never give up. For example, 8 degrees of warming would be much worse than 4 degrees of warming, and could mean the difference between human extinction and the mere collapse of our civilization. The lives of billions hang in the balance, and even if some will inevitably suffer and die, we can't just throw up our hands and let everyone die. Climate change mitigation, cutting emissions as quickly and thoroughly as we can, must remain a priority for the rest of our lives, even if we can no longer reach the best/safest scenarios. Every little bit of avoided global heating matters.

- This post, as dire as its predictions are, may underestimate the difficulty of computing in 2050, given current trends. If you are/were living in Ukraine recently, programming is not most people's top priority, they have other problems. Famines, extreme weather events, and resource wars will affect programmers who live in comfortable locations today. It's not just your users/audience who might be computing from a shitty mobile phone in a refugee camp, it could be you. Don't forget that we're not only dealing with climate change, but with the reaction of other people to climate change: they might want to kill you for your water. And heatwaves are predictable in India/Pakistan, but look at the freak heatwaves in Canada recently, nowhere on Earth is safe, the climate crisis is a global problem.

- Why are we programming what we're programming? Shouldn't our activities and their purposes change given the dramatic change in circumstances? Isn't there something wrong with the system that produced this result, the impending destruction of the biosphere that supports us? Fighting valiantly to preserve the functionality that is killing the world may not be a wise or ethical use of your time. (And if you're programming something for a fossil fuel company, now is a good time to reconsider.)

It's true that programming was not a top priority outside of survival, though to many programmers in Ukraine, it was still a major one.

This report (source: https://www.cnbc.com/2022/03/04/ukrainians-are-built-differe...) from CNBC in March documents this: "Those developers, along with other Ukrainian civilians in the country, are now being forced to defend their homes and cities while sheltering from Russian bombs. But many are still continuing to remotely work for their employers, supporting the local defense effort by day while sending in their deliverables by night.

“Yes our teams are sending deliverables from a f—ing parking garage in Kharkiv under heavy shelling and gunfire in the area. Amazing humans,” Logan Bender, chief financial officer at a San Francisco-based software licensing company, said in a story posted to Instagram on Tuesday by venture capital meme account PrayingforExits. "

I would personally prioritize survival over work at that point, and avoid praising sending deliverables in a warzone as a moral good (over ensuring the safety of your family), but it's evidence that even in extreme conditions, people still want to program as part of their work. As for why there would be a want to program in extreme conditions, some discussions on Reddit and Slashdot in response to the article suggested that programming was a way for these workers to get their minds off their current situation.

I don't know, maybe a war is a bit different. For the first two weeks of it I could not really focus on anything work-related. Worrying whether your city gets captured by the enemy or heavily shelled, being constantly interrupted by air raid sirens, worrying how to replenish supplies, worrying about safety of your family, etc.

Even after I evacuated my family further from the action, we still had missile strikes and air raid warnings. Being away from home, learning about horrible things happening in your country, those things do not help with being productive.

How do you imagine human extinction being an outcome? It seems to me that the worst case scenario is large loss of population which would decrease greenhouse gas output. There would still be some increase in temperature even once we stop emitting, but wouldn't people in colder climates still survive?

There's some fairly absurd doomerism going on in the "climate catastrophe tomorrow" camp where climate change will (somehow) turn earth into a barren rock and we're inches away from triggering a self-reinforcing climate resonance cascade of unforeseen consequences.

It's of course a very urgent issue, but I think exaggerating it until it becomes a threat to "all life on earth" levels is a) dishonest b) does nothing to convince sceptics that it's a real issue, quite the opposite c) is not really all that actionable (at least not in a good way).

> where climate change will (somehow) turn earth into a barren rock and we're inches away from triggering a self-reinforcing climate resonance cascade of unforeseen consequences.

The "barren rock" is a bit of a strawman. Very few if any people believe that the elimination of all life on Earth is in the cards. Human life, on the other hand, is certainly possible.

For the vast majority of major extinction events in history it looks like rapid climate change was the major trigger, and at some point small changes lead to a "self-reinforcing climate resonance cascade of unforeseen consequences", and we currently don't know exactly what the limits are.

This is the focus of a huge amount of the work of Peter Ward and he has written plenty both for scientific and a popular audiences.

Now he may, of course, be wrong. But his work is credible enough that you have to at least take into account that the real risk of extinction is possible.

Re:Programming in the Apocalypse by goatlover on Tuesday May 31, 2022 @12:44AM (#31566186)
It's hard to imagine how climate change would lead to human extinction, since humans have inhabited such a wide range of environments across the globe for thousands of years, have technology to help cope with extreme climates, and are vary adaptable. What would make every single environment unlivable for humans? I don't believe there is a single climate model that does that.

And how many climate scientists actually believe extinction is on the table? I've seen some say collapse of global civilization and mass death is a possibility under the worst case scenarios, but not really anyone claiming all humans would die. Anyway, the latest IPCC report puts the upper range of warming at 3.7°C. Which is bad, but not the apocalyptic hot house Earth scenario. But even with that, some environments will still be livable. People live on mountains, near likes, far inland, way up north and all over the place. Earth isn't going to turn into Venus, and it was a lot hotter when the dinosaurs evolved. Plants and animals still survived after the Permian die off.

Human life today is mostly maintain with infrastructure (water, food, security, health, etc). A cascade of failure due to climate change can destroy all but very local and small infrastructures. With society eventually returning to a pre-industrial conditions. It is not the end of humanity but the pre-industrial world economy can't support food, water safety and health care for 9 billion people. In pre-industrial era world population were less than 1 billion, we might return to these numbers. That means death of the large majority of human. Not extinction but the biggest threat in human history.

Well, hundreds of millios displaced and/or dead would be enough. Doesn't have to "turn earth into a barren rock".

And as for "suddenly", many systems tend to have a breaking point, especially systems, like the environment, which have feedback loops that can easily feed into each other and make things worse fast. Collapse is seldom linear or a nice gradual curve.

Actually, yes it does. The OP specified "human extinction". We're arguing that single point. The fact that thousands/millions/billions might displaced isn't being contended.

40% of insect species are declining and 1/3 are endangered. In terms of biomass, we're losing 2.5% of all insects every year at the current rate. Insects are essential contributors to the biosphere, both as pollinators and as food sources.

If that's not a "threat to all life on earth," I don't know what is. And that's just what I could find with 5 seconds of googling.

The point the OP is making is that wiping out all life on earth is an impossible and silly benchmark. No-one sane thinks 'oh, but we don't have to do anything about climate change because some worms will survive around the thermal vents on the ocean floor'

To 'wipe out' life on earth, you have to crash the moon into it or do something similarly ridiculous - remember that a giant asteroid wasn't enough.

Wiping out all human life is possible, but again I don't think that anyone is comforted by the idea that 0.1% of the population might survive in an arctic cave.

Where we seem to fail is in communicating to folks that don't want to spend money to fix the problem today how their life will become miserable tomorrow.

Re:Programming in the Apocalypse by actually_a_dog on Monday May 30, 2022 @08:41PM (#31565073)
If we lost all the insects in a ~100 year period, the result would be close enough to losing "all life on earth" for anyone who doesn't have a microscope (or, more likely, a telescope). This is not an exaggeration in any sense of the word.
Re:Programming in the Apocalypse by goatlover on Tuesday May 31, 2022 @12:50AM (#31566216)
We won't lose all insects. They didn't all die off when a massive rock took out the non-avian dinosaurs 65 million years ago, and that was far more catastrophic (worse than any human nuclear winter scenario).

Might’ve taken a while to grow back though.

The loss of insects isn’t caused by climate change, it’s too much pesticide use and people trying to have lawns instead of native plants.

The temperature and co2 levels have been much higher in the past. The earth has been much more tropical as well as an ice world. Humans can adapt to change quite effectively - we did invent air conditioning, as well as the land of The Netherlands which is reclaimed and existing beneath sea level.

What is the greatest tragedy is how much worry and anxiety climate change causes. The earth is not a thinking thing - “Mother Nature” is not a being. The planet will exist and doesn’t care about humans. A century after the last human lives nature will swallow up almost everything we built. Earth exists for humans because we live here and make it so. We will adapt to whatever climate exists.

It doesn't matter what Earth was like at some point in the distant past. There weren't 8 billion humans living on it. It's not easy or cheap to move cities with populations in the millions because sea level rise puts them below water.

Humans can adapt to climate change but it's very likely to be very painful and very expensive.

There are a large number of things that could kill everyone, but I think the top threat will always be ourselves. It's very easy to imagine some resource war degenerating into a nuclear war. A few self-induced crises like that on top of the climate crisis would be enough to finish the survivors (who might have made it if the only danger were the environment).

Think of the world population's size and global distribution as hedges against disaster: the fewer people who live, in fewer habitable places, the more likely it is that some disaster will affect everyone remaining and leave no one unaffected. We have fewer rolls of the dice, and there may come a day where they're all snake eyes.

This why many are excited about the idea of "making humanity an interplanetary species", as I once was until I realized how hard it would be to make a working biosphere anywhere else, given how bad we are at maintaining one that already works. If we don't figure out how to save this biosphere, we won't have enough time to make more.

True human extinction doesn't seem plausible, but in a worst-case scenario we can imagine a > 99% drop in population, roughly to what is sustainable without technology, in a dramatically harsher world.

("Without"? Well, nobody today knows how to build a cast-iron plough.)

I don't believe this scenario is likely. For one thing we're not headed for 8C of heating; for another, technological change seems to be coming just in time to head off the very worst outcomes, assuming we struggle hard enough.

Re:Programming in the Apocalypse by skyfaller on Monday May 30, 2022 @03:25PM (#31562660)
We probably aren't headed for 8 degrees of heating, based on what we know today. There are a lot of "out there" scenarios that don't make it into sober, conservative scientific reports from the IPCC, because they recognize how important it is that people take their warnings seriously, and they don't want to mention anything they don't have very clear evidence for already.

One of my "favorites" is the "world without clouds" scenario, which for the record, I consider unlikely, but is horrifying to imagine: https://www.quantamagazine.org/cloud-loss-could-add-8-degree...

What we're dealing with are "unknown unknowns": what tipping points might exist that we don't know about, that might result in more warming faster than expected based on today's science? We shouldn't take those kind of existential risks.

The comment section is full of clueless numpties that do not understand what 4 degrees REALLY means, and think it won't lead to collapse.

When the world was 4 degrees COLDER Chicago was under 900 meters of ice. Toronto was under two Kilometers of ice.

Do you think that would cause collapse of civilisation? How are you going to adapt to a glacier covering all the farmland? No technolgy, not even nuclear bombs, can remove the billions of tons of ice that would be covering all the farmland. We could not even protect cities, the moving wall of ice would buldoze every structure we've build and then whoever didn't freese to death would die of famine.

We are headed for a 4 degree change in the OTHER direction. That's what we are headed for by the end of the century

The biggest mistake climate scientists have done is communicated their change in terms of degrees, so people think about their everyday experience with weather, which obviouslty changes much more than that, and think they will just sweat a bit more in the summer.

Re:Programming in the Apocalypse by XorNot on Monday May 30, 2022 @10:37PM (#31565594)
To be very specific: people who think increase isn't dangerous need to look up web-bulb temperature [1].

There are regions of this planet where an average 4 degrees increase will mean that for periods longer then 24 hours, multiple times a year, the wet-bulb temperature will exceed 35 degrees C. That is unsurvivable by human life. Your only options in that environment are to not be in that environment by either escape or technological means.

There are cities built in areas where this is a risk, and if it happens they will just be depopulated: it is not possible for millions of people to escape an urban area under a heat wave. If they're somewhat built up, then they might survive it provided the electrical grid holds out - which, as recent experience globally should show - is questionable. Remember: under these conditions, no repairs to external infrastructure are going to be possible - you would need active refrigeration to move around outside and survive. We are not remotely adapted to that sort of hostile environment.

Most likely we are a decade or two out from a climate-forced mass casualty event, probably in the Indian subcontinent, with more minor (slightly less mass death) occurring in parts of Asia earlier.

We have 28 years left and emissins are still increasing. We have to reduce emissions by like 40% per decade, which is not happenning at present.

You misread their statement. They said "8 degrees". With 8 C increase in temperature, what they described could very much happen. We expect 4 C worst case, which is why we do not need to worry about extinction. I think they are saying that we do not need to worry about more than 4 C increase exactly because people in the past fought for the cause, and if they stopped fighting the same way today some people feel resignation and want to stop fighting, even 4 C would have been too optimistic. The fact that people in the past did not resign themselves to the status quo is why we do not need to worry about an 8 C increase.

If you read mainstream publications, then you will gradually form an opinion, which is that there is a climate emergency, but not that humanity will be destroyed.

Humanity probably will not be wiped out, but the current global civilization will collapse like it happened to many other civilizations before because they reached the ecological overshoot. I also thought that something "could be done" on a large scale, but after studying the problem in depth (starting with the IPCC report), I began to prepare on the community level for the impact in the next 10-20 years. That's the only area where something can be done.

By the way, BBC is not a reliable source, like other neoliberal propaganda they bet on continuing "business as usual" while coming up with some innovative solutions (so-called "techno-hopium").

I'm assuming celsius, not farenheit.

I'm curious why a mere 8 degrees increase leads to human extinction.

Is that "8 degrees evenly over the globe"? If so, that most certainly would leave the majority of land arable and comfortably livable.

Is that "8 degrees average with such a high deviation that no land is left with a year-round range of 0 degrees to 30 degrees"? If that is the case, where can I read/view/see the model that produces such an extreme outcome?

Few models deal with warming beyond three degress, in itself a point of some consideration, but the references are all there and here's the synopsis for the book.

> At one degree - the world we are already living in - vast wildfires scorch California and Australia, while monster hurricanes devastate coastal cities. At two degrees the Arctic ice cap melts away and coral reefs disappear from the tropics. At three, the world begins to run out of food, threatening millions with starvation. At four, large areas of the globe are too hot for human habitation, erasing entire nations and turning billions into climate refugees. At five, the planet is warmer than for 55 million years, while at six degrees a mass extinction of unparalleled proportions sweeps the planet, even raising the threat of the end of all life on Earth.

Some possible runaway events include the aforementioned loss of clouds which in turn won’t reflect back that much sunlight (which currently can account for 30-70% of sun light not hitting the ocean water), melting ice will free lots of trapped CO2, changing climates may alter currents and winds causing very large-scale changes to certain areas (and might also affect cloud formation), etc. We are in a big, closed jar and that 8C change may not be a problem locally, it is that much more heat trapped globally.

But one should add that life is unlikely to die out in even the worst predictions (life, finds a way), but you still don’t want to find yourself in the situation where you will have to literally hunt down other humans because they may have food, or try to migrate with 100s of millions of other agitated, hungry people to nations which won’t be friendly to you because they themselves have enough problems to begin with.

It doesn’t. It’s an extrapolation based on the limited insights of a PhD who by any reasonable definition spends too much time with simulations.

If you want to think of a way it could be possible, though, think of those areas that would be habitable, realize that they would be highly contested, are mostly presently permafrost, and consider your own ability to both protect and survive on melted tundra and reproduce there, given you will starve in a single season without food.

I actually did consider that first - that maybe at +8c humans will kill each other, but that's just pure speculation.

And, sure, food is necessary daily and constantly, but the situation you outline isn't an overnight thing. Hell, it isn't even a 100-year change, +8c is a lot longer.

That gives you plenty of time to move, and at +8c, as long as it is stable at +8c, you'd still have enough arable and livable land to ensure that humanity is nowhere close to extinction.

So if it isn't lack of land, and it isn't the temperature range that causes human extinction, what does?

I think it is incredibly unlikely personally. We have evolved nearly beyond environmental dependence, certainly beyond local environmental problems, and it is difficult to imagine our extinction as long as there are some plants and insects that survive. Possibly we could even persist on algae farming.

But if you add the fact that antibiotics will be in short supply, novel zoonotic diseases will ramp up, and most knowledge of how to survive in the wild has been lost and probably can’t be reconstituted in a couple of violent generations, I can see how it could come about.

There is also the social and psychological impacts of that scale of loss, and there are some other sort of scary indicators you could lean on (Calhoun rat experiments) to indicate that there are limits to what animal populations will reproduce through.

I’m not worried about it — we seem like a pretty robust system from my perspective. But it is interesting to think about abstractly.

> For example, 8 degrees of warming would be much worse than 4 degrees of warming

You should review where you got those figures and whether they are representative enough of current scientific consensus regarding the most likely scenarios.

As fas as I know and assuming that current pledges are fulfilled, most plausible estimations tend to be around 2 or at most 3 degrees of warming above pre-industrial levels (we are already well over 1°C).

While it is clear that this increase in temperatures will have severe consequences, I fail to see how it would lead anywhere near the civilization collapse that you seem so confident in predicting.

See for example: https://www.nature.com/articles/s41586-022-04553-z.epdf

That's a pretty big assumption, to assume that current pledges will be fulfilled. Last I heard, it was just, like, Gambia that was on track to meet Paris Agreement pledges. https://www.cnn.com/2021/09/15/world/climate-pledges-insuffi... None of the G20 countries are on track.

The point of the Paris Agreement pledges is to prevent catastrophic global heating, so it would be great, although in my opinion inadequate, if the world community met them. Sadly, we're not heading in that direction right now.

I expect that people will still write software because it needed and pays well. However, the jobs that people get paid to do could become rather different.

Consider what happens in a war. The people working on drones aren't just hobbyists, they're part of the war effort. Wars are not good for the environment, either.

So my guess is that, if it gets really bad, these jobs will focus more on short-term needs. Are people who are really focused on preparing for heat waves and drought and flooding going to give a hoot about being carbon neutral? An overloaded hospital is going to focus on the patients, not global environmental issues.

Both "it's needed" and "pays well" are the case now - not necessarily the case at that point. So they can't be used as arguments that people "will still write software" (it would be taking for granted what must be proven).

Then again, demand for fossil fuels is also part of the equation. You get a remote programming job, demand to travel by car potentially goes down. So there's potentially a net reduction in emissions.
