      Well said. Ultimately knowing that it is too late (for those with the power) to prevent the feedback loop is not truly defeatist - or its opposite. Defeat and victory are no longer relevant here, the Climate Change Game (which we were never playing) is over, the scores are tallied.

      I don't need to believe that 'my civilisation' will successfully survive after I die in order to want to improve it somewhat, or prepare for potential future generations. I try not to attend to such matters out of the expectation of success/reward or failure/punishment (y'know barring the part where me-want-eat), but because it is preferable for the world to be harmonious regardless of its fate. It's a happy coincidence that adaptation to climate/biodiversity collapse is also extremely compatible with, if not contingent upon, the kinds of systemic transformations I work towards.

      We are all going to die.

      We're not all going to die. Which is to say we are all going to die, but everyone has always been all going to die forever, so we're not unique or special in that regard.

      We are unique and special in that we have foresight into the string of natural catastrophes that's going to kill billions of people, and that's well underway, but that's a far-cry from an extinction event. Way more of a slower, preventable Black Death for someone in the imperial core.

          I mean when you lament that are not people 'are not getting it', you seem to indicate you think they should also think that. Which, why are we wanting people to take the Denethor route on this again?

          I mean, if you want to adopt this floating point gnosticism of "the models say we're all going to die horribly, so we need to take that as a given", you're welcome to, but I don't think we should want that to be the default leftist position because it's bad science and bad philosophy of science

              The world being utterly fucked because if the climate is more or less the default consensus of climate forecasts. How is it bad science?

              Because contrary to depictions like "The Martian", numerical models don't output things like "world is utterly fucked". They spit out norms and aggregate quantities and if you're lucky interval estimators. "World is utterly fucked" is editorializing, defensibly if "utterly fucked" is conservatively construed and indefensibly if utterly fucked is liberally construed.

              Look, it's not going to be pleasant, you're going to see billions of premature deaths from this, but the who and where of those deaths are all inexact, inductive predictions. Absolutely none of models and I doubt any of the scientists (certainly not the ones I know personally) are saying we're all going to die (from this).

                  I'm a philosopher of science specializing in climate models. I think your presentation was fine. The models are very clear that we're entering a regime that will cause vast swaths of the Earth to become hostile to human life for large parts of the year. This is a catastrophic emergency.

                  700 other things, will work will come to be will impact and change the climate and our lives specifically

                  See, you can't do that, because no one can, because these systems are coupled in inexhaustibly complex ways. Even the coupling of system of climate models is inexact. I know this because I have my PhD work was in numerical models of systems very similar to climate models. I know enough about it to not let someone else's finite-element NS solution ruin my weekend.

                  It's cheap, easy and free, to say online that 'we're all going to die of climate change', but it's one of ways of saying something that sounds smart without ever actually saying anything at all. It's the tired twitter-style argumentation of offhandedly making a prediction that will not and cannot be validated that no one will remember when the bill comes due.

                  Negligicing the death of billions is cool too, yeah one way to put it is definitely that it "will not be pleasant".

                  200 million people died in the 20th century due to the combined effects of alcohol and tobacco, but no one makes it a personality facet to post online about "death stalks the land, great bilious clouds of poison and tar churn out of every dive bar while inside men are drowned in cirrhotic frenzies, it's only a matter of time for me". We have a moral obligation to do what (little) we can to stop the capitalist death machine that is driving this climate catastrophe, and to help individuals in it's path when and where we can, but I'm also not terribly impressed by your pretending to deeply, personally care about abstracted projected megadeaths to shore up a shoddy intellectual position.

                  Look, 700 migrants just drowned off a single boat in the Med, for reasons adjacent to and attributable to climate change. Neither of us are doing anything about it, so I don't see what moral benefit your or my doomerism offers them.

                      Damn I guess I gotta ignore all the climate reports that conclude that we are all going to die,

                      Show me a single report that says this verbatim please.

                      Same goes for sticking your head in the dirt saying "well be fine actually".

                      "Billions will die" is not "everything is fine". "It's not going to be pleasant" is not "everything is fine". I don't know if any particular individual is going to die from climate change or not, because I understand the models model aggregate behavior. I could die of climate related reasons, or I could get hit by that jerk in the pickup. I don't know. You're the one who's willing to tell everyone "you're going to die of climate change driven starvation" without grappling with the inherent complexity and inexactness of the models.

                      People being displaced due to hunger, famine, and battles for territory as livable space becomes less and less available is unrelated to climate change, ok

                      Literally said the opposite.

                      "You claim to be worried about the apocalypse, but you did not decry the people already dying from starvation, curious

                      My point is the apocalypse is already happening, and has already happened for large swaths of humanity. You're hyperfocusing on a single (albiet important part) as some sort of weird internet subculture. Which is fine, but not a requirement for leftism.

                          So to sum up, you're frustration of 'people not getting' stems from them not feeling about the future what you feel about the future despite the fact you acknowledge your feelings don't really reflect the reality of what is going to actually happen in the future?

                          WHAT THE FUCK? Do you go into a post about how to make pizzas and complain when people discuss what type of flour is best to use???

                          You talk about being frustrated that other people don't feel the same way you do about a specific form of doom, and I so I tried to explain why a lot of people wouldn't feel that way about that particular form of doom given the wide variety of dooms to choose from and the inexactitude of predicting anyone's actual form of doom.

                          Seems apropos to me, but then again, just some guy.

                  I mean I think it's important to be clear when stated positions don't hold up to rigorous logical scrutiny, not because we have any obligation to have logically coherent positions (because no one does certainly not me lol), but because they're a certain type of impressionable dweeb (me 10 years ago) that will adopt positions because they seem ostensibly logically sound, and I don't really think we should evangelize doomerism.

                  When I was like 10 a documentary on the big crunch at the local planetarium left me horrified for like 6 months. So when someone says thinks like "we're all gonna die", I am gonna caveat it all to heck as appropriate just as a matter of principle.

                      I mean I'm not sure I agree with your post. I agree that things are gonna get continuously worse for large swaths of the population likely including myself, but I don't think that means we're all doomed or that I should spend too much time thinking about that or aligning with an internet subculture that hyperfocuses on that.

                          Right, and I don't think you're a bad person or dumb or even terribly wrong about any specific factual claims that underlie the doomersism, and I still think it was a conversation worth having.

                              I think it's important, both socially and politically to combat the notion that emotional doomerism is an intellectual necessity so we're going to have to agree to disagree there as well.

                                  You did not ever say it was a necessary, but I think that a plausible (not the only or even intended) reading of your post made the implication that the sheer weight of facts should compel a person to that position. And so I jumped into make sure that everyone was clear that it's not the only defeasible position to hold, and I'm glad to hear we might be in agreement on that fact.

      We are all going to die.

      this isn't true in the most literal sense. we have a couple of opportunities to avert the worst crises, but even beyond that, we won't all die. most will and it will be bleak but people have been finding ways to survive against impossible odds for at least 2 million years. our way of life has an expiration date and our society, as presently constructed is doomed, but many people will survive. probably not most, and the vulnerable among us are fucked, but it's not going to be all of us, even if the earth warms by 6 degrees.

          idk mate, that discussion doesn't really clarify anything. "we're all going to die" is indisputably going too far and it's a meme that needs to die. it's an agency murdering nihilism - we can do things in the present to limit the damage. it's a rhetorical point but I think it undercuts your argument. you can't cite science and slip to vibes without people rightly calling you on it.

                          I disagree with the factual claim - I've seen no data to support it. you've said both that it's how you feel and that it's a factual claim, separately at different times. if this is purely about how you feel, I suggest in the future not trying to lean on the science. if you have studies that show that an extinction level event is plausible or likely, I'd like to read them.

            No it's not. It's not going too far to recognize a very real possibility, even if there is still hope that we might be able to avert it. And it is absolutely NOT agency-murdering nihilism to not stick one's head in the sand and pretend it can't happen. To me, the possibility (even likelihood) that our limited time is nearing its limit, encourages me to do everything I can to improve people's lives and material conditions here and now and bask in the fleeting time we do have on this globe, both as individuals and as a species.

              Look either you're talking about how we're all going to die generally, in which case there's nothing we can due to avert it, or you're saying "we're all going to die of climate change", which implies a Venus level degradation of the biosphere that none of the models seem to pointing toward, or you're inappropriately assigning probabilities of death of unspecified large numbers of people to specific individuals.

                    Climate change has an actual and real potential to end our species in the relatively near future. We have already kicked off a mass extinction event that has only just begun. I "offered backing" for this in other comments in this thread, discussing it with someone who demonstrated a willingness to have a conversation, not just debate-bro-reddit-style demand evidence from me for something any decent climatologist would straight up tell you.

                      Climate change has an actual and real potential to end our species in the relatively near future.

                      A gamma ray burst has an actual and real potential to end our species tomorrow. Yet it would be wildly irresponsible for me to tell people that they're going to die in a gamma ray burst.

                      not just debate-bro-reddit-style demand evidence

                      The implication that it is somehow rude to insist that you back up positions that can actively cause distress in other people is not one that I'm going to accept, so complain about "debate-bros" at your leisure but don't expect me to care.

                      something any decent climatologist would straight up tell you.

                      And yet neither you nor anyone else here can point an actual example of any of them actually saying human extinction is very likely based on their projections. My climatologist friend is getting married in August. I'm going to the wedding. They're planning to have kids.

                        Ok, here's the first result in a duckduckgo search:

                        Catastrophic climate change outcomes, including human extinction, are not being taken seriously enough by scientists, a new study says. .

                        Second result

                        Will Humans go Extinct? Death by ecological contamination or the climate emergency would be slower but still within the realm of possibility. .

                        Third

                        Climate endgame: risk of human extinction ‘dangerously underexplored’ .

                        Happy now? I hope you realize how reddit-tier it is to demand sources like that when you can easily do a search without forcing the person you're talking to to do it for you with the implication that they're full of shit if they don't do your homework. Not to mention the "well my best friend is [expert in field being discussed] so nyeah."

                          From the study cited in two of those articles.

                          This caution is understandable, yet it is mismatched to the risks and potential damages posed by climate change. We know that temperature rise has “fat tails”: low-probability, high-impact extreme outcomes (9). Climate damages are likely to be nonlinear and result in an even larger tail (10). Too much is at stake to refrain from examining high-impact low-likelihood scenarios. The COVID-19 pandemic has underlined the need to consider and prepare for infrequent, high-impact global risks, and the systemic dangers they can spark. Prudent risk management demands that we thoroughly assess worst-case scenarios.

                            lol. So you quote one of the articles as a gotcha? The one that talks about another "low-risk" event that DID HAPPEN and that literally just killed off tens of millions of people? Yeah, that's a great refutation of my statement about climate change induced extinction being a very real possibility... by pointing out a low possibility but very real threat that literally just happened. And is still happening... despite mass denialism. Wow. Please, by all means, prove my point further by trying to own me some more.

                              A roulette wheel came up red 32 times in a row in 1943, so you should go buy a lottery ticket right? It is a very real possibility that you could win, and anyone that claims such "I am going to win the lottery tomorrow" is not supported by probability is being needlessly pendantic right?

                                To use the example you were using from the article to apparently try to own me... Covid was the red 32 times in this analogy. It happened. Funny how in retrospect, they are both actually something of an inevitability if the warnings of people who did predict them aren't heeded. Just like rolling red 32 times is if you have millions of wheels continuing to spin without stopping, guess what... odds go up. No, I'm not going out to bet my life savings on 32 red in a row tomorrow. The same way I'm not nor did I *ever imply we're all literally going to drop literally dead literally tomorrow. But 32 red actually happening somewhere in the world at some point in the very past? Yeah... hmm.. it happened, go figure. Thanks for reminding us all that even seemingly low probability events actually really do happen.

                                    Sorry for the late reply, I actually didn't log in for the last couple days after this.

                                    Hey thank you for digging into this as well. The pedantry is tiring.

                                    Thanks for doing the lions share of trying to push back and reason with the deluge of pedantry, in this thread but also in others I've seen too. I'm convinced that when people start using that as a tactic in their argumentation, they're no longer arguing with me anymore so much as their own cognitive dissonance. They know on some level they're just plain wrong. But that's too hard to own up to, so instead they try to find something to nitpick at in your wording. If they can shift the argument into focusing on some insignificant hole in your phrasing or onto an analogy you used that isn't a complete and perfect 1-to-1 example, they can feel emotionally safe in writing off your position. Then they can likewise feel emotionally safe in not having to examine their own position and can continue feeling Right and Correct that they know the Truth.

                                    I know I'm not saying anything new, but it helps to remind myself of that when having to put up with the kind of bullshit you were getting swamped with in this thread (that I also waded into). It's especially frustrating to have to put up with it here. And from a mod apparently too. cringe

                                        the "we're all going to die" was something someone else said if you're so caught up on that kind of ridiculous cringey pedantry, but what they were referring to was human extinction as a result of climate change. If you are truly incapable of understanding context or anything but the most literal and absolute interpretation of any combination of words ever used, your qualm is with them. No one, not even the person I was disagreeing with who said that, believes anyone was ever saying "every person reading this is going to die tomorrow and it is 110% absolutely unavoidable."

                                        What is being discussed here is climate change ending the species. Which remains a very real possibility, which is what I said, which is what everyone here who reads this, even you, knows is what is being discussed. It is not only NOT irresponsible to point out this very real possibility, it is irresponsible and foolish denialism to imply otherwise.

                                        Now kindly sod off, you bad-faith-arguing, asinine pedant. I won't be reading anything else you say to me.

                            hahah my god, I am back on reddit. I thought I had gotten away from that. I wonder where the goalposts are going to be moved next. Doesn't matter, I'm just going to refer you back to what I actually said several comments ago: "Climate change has an actual and real potential to end our species." As for the demand of specific scientists, they're referred to right there in the articles I already presented, which I shouldn't have gone to the trouble of finding for someone obviously unwilling to engage in actual discussion.

                              Climate change has an actual and real potential to end our species.

                              This is true, and if had been where we started, I wouldn't have objected. Where did we start actually though?

                              "we're all going to die" is indisputably going too far and it's a meme that needs to die. No it's not. It's not going too far to recognize a very real possibility

                              very real possibility implies a probability threshold that you absolutely cannot substantiate. Telling people they're all going to die of climate change is a far cry from the much more reasonable claim "climate change driven extinction of the human race a possibility in the coming centuries".

                                I substantiated it by giving you articles that said it's a very real possibility. You quote one of those articles that is saying "yes, it's a very real possibility" but because they also use the words "low probability" of that very real possibility, you think... you've refuted something I said. One specifically talking about a low-probability event that was a very real possibility... because IT HAPPENED. This is... I can't even... picard

                                  So when you say "very real possibility", you don't mean to imply anything about the probability of that event. You just mean "possible possibility"?

                                  The article doesn't even say 'very real possibility' for the record so I don't know why you're treating that as a verbatim quote to show correspondence with your position.

              anything is possible - we can't know the future - but I've read no studies that suggest that literally everyone is going to die. I encourage you to read the whole of the IPCC reports. the summaries leave a lot out and the actual data paints a bleaker picture than what's in the top-level summaries - but I saw nothing that supports the idea that an extinction level event is likely. the clatharate gun would have to go off for that to happen and all indications at present are that the thawing of the permafrost is not resulting in a spike in methane levels because plants are growing in the former permafrost and repurposing the methane.

                the actual data paints a bleaker picture than what's in the top-level summaries

                There's a reason for that. I've read of meta studies that show climate scientists deliberately downplay how bleak the situation really is, mostly because of political pressure but also because they are afraid of mistakenly spreading paranoia.

                What any good climate scientist will tell you is that we fundamentally don't know all the feedback loops we have already tripped and know even less about ones that will inevitably be tripped. For example, it's looking likely that Venus was once a lot more Earth-like in terms of what we consider habitable but now for reasons (volcanism?) that aren't entirely clear, it's surface is utterly inhospitable even for extremophiles. We could have already tripped a runaway greenhouse effect without yet recognizing the exact mechanism, but we do know we are changing the climate in ways faster than at any other time outside of mass extinction events. (And we are in the midst of a mass extinction event already, just at the very beginning of it - hence the term anthropocene). Earth has been cold enough in the past, likely several times, that it was completely frozen over, with maybe the exception of a narrow band around the equator. Earth has also been hot enough that animal life has only been able to survive at the poles. Humanity would not survive this. Humanity, despite our spread and obvious adaptability, is also an extremely fragile species for reasons similar to why technology that requires complex supply chains is fragile to sudden shifts.

                Human extinction in the next few centuries is not by any means far fetched. That's not to say it's guaranteed, of course, but pretending like it's not in the cards is naive.

                  yeah, that's my read as well.

                  We could have already tripped a runaway greenhouse effect without yet recognizing the exact mechanism, but we do know we are changing the climate in ways faster than at any other time outside of mass extinction events.

                  the present models do their best to accommodate for these unknowns. they're likely wrong and things might be even worse than predicted - we can only account so well for the things we don't know - but the worst case models for runaway CO2 warming don't lead to the earth becoming Venus. they lead to the Earth becoming something like what it was during the Jurassic. it's methane warming that will actually annihilate humanity and the current data on that front is cautiously optimistic (see my earlier point about plants absorbing the methane trapped in the permafrost).

                  Humanity, despite our spread and obvious adaptability, is also an extremely fragile species for reasons similar to why technology that requires complex supply chains is fragile to sudden shifts.

                  this contradicts the biological record. human species have adapted to thrive in more environments than literally any other species on earth, excepting the extremophiles. that's not to say that extinction is impossible, only that it's going to take more than displacing the vast majority of people and a collapse of the food chain. if plants are growing, pockets of humanity will find a way to eke out an existence.

                    I agree with pretty much all of this except for the last bit, which is a lot to get into right now (other species that existed globally going extinct, the surprising youth of our species, genetic bottlenecks pointing to how insanely close we've already come to extinction when climate change wasn't an issue or was so much slower as to hardly be a comparison now, etc.) All that aside, taking everything you said into account, it's still folly not to recognize human extinction in the near future (geologically speaking) as a real possibility and worth considering. Especially given how many unknowns still exist with respect to feedback loops.

                    But what I was mostly refuting when I first replied to you was the claim that recognizing human extinction as a possibility is "agency-murdering nihilism." And I hope I did that. Again, for me that recognition has gone quite a ways towards making me a better leftist.

                      I'm not saying that it's impossible for us to go extinct. but the climate is going to have to approach Venus levels of bad for even small pockets of humanity to disappear.

                      recognizing the possibility is natural and good - that billions are going to die should give everyone cause for reflection. my point was more about the conviction and certainty of the claim. it's just not in line with the best science available right now. saying "our civilization is likely doomed" is a defensible claim. so is "it's possible we go extinct" is also defensible. saying "literally everyone is going to die", without qualification, is nihilism. it's a philosophical path that leads to accelerationism or other forms of reaction.

                        but the climate is going to have to approach Venus levels of bad for even small pockets of humanity to disappear.

                        No. If Earth's climate begins to approach Venus levels of bad, humanity will be done and gone long before that. Extremophile bacteria right now wouldn't be able to survive on the surface of Venus where it's hot enough to melt lead. There is no reason to think this isn't also possible for Earth (in fact it's an inevitability, just far enough out that humanity is statistically likely to have gone extinct for other reasons first). I really don't think most people comprehend how narrow the range is for continued habitation of animal life, let alone mammalian, let alone one species of mammals. The whole idea that "even with catastrophic environmental collapse, we intrepid humans will find a way! We'll eke out an existence and pull through!" strikes me as the same kind of thinking that allow Musk fans to talk about colonizing Mars as if there's even a remote chance even within the next couple generations. Imo, the failure to recognize human fragility is a kind of anthropocentrism and unintentional hubris. Yes, we have spread over much of the globe but only during a brief (geologically speaking) time when everything was nearly perfect for us. And even then we came so close to extinction where literally only a few thousand individuals existed on Earth and as a result we have very very little genetic diversity (which tangentially, unrelated to this conversation, is another fun fact to throw in the faces of racist reactionaries). Many other species have spread more effectively and over far more of the globe than we have and the vast majority of them are already exinct.

                        Again, Earth already has gone through climatic events that humanity, even with all our current and modern technology, could not survive. Humanity wouldn't live through a "snowball earth" which has already happened. Humanity wouldn't live through a permian-triassic equatorial pangaea which has already happened. The latter included a runaway greenhouse effect - something we may have already tripped. It's not even the first time that life is what caused it's own mass extinction. Human extinction level climate change is in the worst-case-scenario realm. But something else you probably already know about, something heard often in climate-aware circles, is how many of the projected "worst case scenarios" of the last few decades have turned out to be what actually came to pass.

                        saying "literally everyone is going to die", without qualification, is nihilism.

                        Humanity will last longer than the lifespan of anyone here, even the children of anyone here, I think it's safe to say. But it will not and can not last forever. Why is it philosophically acceptable when the fact that an end of humanity will happen is qualified with whatever sufficiently large epoch you personally want to put on it, but it is unacceptable "nihilism" to suggest it could likely happen in the next couple millenia or so?

                        it's a philosophical path that leads to accelerationism or other forms of reaction.

                        Why? Does someone given a terminal cancer diagnosis necessarily want to just go out and (CW) intentionally end their lives all the quicker (accelerationism)? Or decide they may as well become self-serving assholes and do their damndest to take everyone else out too (reaction)? I'm sure it's happened but it's obviously not the norm. It's difficult, it's painful, it's terrifying to contemplate when the end is nigh (on a personal level, a civilizational level, or at the level of a species), but it's not nihilistic to accept it. On the other hand, it would be philosophically naive though understandable if a person couldn't accept it.

                        The only thing that my so-called doomerism has changed as far as my behavior is inspire me all the more to try to do what I can to increase human well-being and the well-being of all sentient life while I still can. And I know I'm not the only one, I'm reminded of Breht O'Shea from Rev Left Radio who has frequently talked about the difficulty he's had in reconciling with the reality of climate change but how much better of a leftist and person it's made him.

                        Climate "doomerism" is not and does not necessitate nihilism, and it definitely isn't in conflict with being a good leftist.

      It’s good to organize now because we still have to live and aren’t dead yet. Being a bloomer is unnecessary unless you’re trying to make people comfortable. rust-darkness
