    no shit eh? This seems so wildly obvious that i don't really know how to read it. the Pacific North West hasn't seen significant snow in years, instead of our daily fall rain we've been getting awful downpours that flood everything followed by weeks of dry. snowpacks gone, reservoirs are running dry, fires are more and more devastating every year.

    when are we going to acknowledge this catastrophe that we are barreling towards?

    i can only hope that things start improving. between this and government im gonna lose it

    Not to be a total downer, but probably never unless all the Republicans in the US suddenly disappear? Like, remember who the "we" is in your question. Remember what policies they stand for and what methods they employ.

    It's crazy because while the US is one of the biggest emitters per capita, it's also home of the brightest minds and have by far the most efficient research ad development capacity. So US govt. denial is a huge hit in our already tiny chances to save the planet from hell in the next 50yrs.

    Is this still true?

    China seems to be winning now. And lead in solar, and robots.

    China seems to be winning in brightest minds by what metric?

    >And lead in solar, and robots.

    And new coal, don't forget about that.

    A lot of the "brightest minds" are, and have always been, immigrants.

    Guess who is the main target of a purge in the US now.

  7. 7. drstewart||context
    Poor economic refugees from unstable countries.

    The same immigrants that Europe, Canada are now rejecting and Asia never even allowed.

  8. 8. breakyerself||context
    For decades the US has managed to be the most powerful economy in the world while taking in tons of these immigrants. Rejecting them is likely to have a negative impact. Xenophobia comes at a cost.

    The brightest minds in STEM are often loudly, proudly, confidently wrong on every single thing except their narrow specialty in STEM.

    Many of the people still rejecting climate change are scientists and engineers whose egos make them obligate contrarians.

    This.

    I'm appalled that there still seems to be the need to find _evidence_ for this.

  11. 11. kuerbel||context
    Those people are not convinced by evidence.
  12. 12. criddell||context
    Which is why it's a bummer that the last good communicator on the topic was probably Al Gore. Lots of great science that I'm happy to see done, but there's nobody out there doing a very good job of making people care.
  13. 13. breakyerself||context
    I think Al Gore did more harm than good. He made himself the face of global warming and it helped spark a partisan backlash. There was a time when Republicans were not particularly skeptical of global warming. That shifted as climate change and Al Gore became more and more synonymous in the public consciousness.
  14. 14. criddell||context
    I think Gore's road show was pretty good, but I can understand your argument.

    Probably the last person who was able to effect positive change was Nixon.

  15. 15. poidos||context
    There isn't, right? Their gameplan is to state a need for evidence to delay, delay, delay while they and their backers enrich themselves at the cost of everyone else.

    Decarbonization, reduction of produce (spending less), trash collection and reduction, less plastics… and hoping for the best that mankind wont mess it up more til 2050 - then the following 100 years (after 2050) shouldn’t be so hell as it seems so now…

    Unfortunately we as people cannot see our older ones so future planning is not so easy…

    Guns and ammo was the conclusion how to prepare for the future - in the book “10 Billion” by Stephen Emmott.

    It's pointless to look for solutions that's against human nature.
  18. 18. soco||context
    So the human nature is to kill ourselves or otherwise let ourselves die out? Sorry dude, I don't want to accept that - I don't even believe it.
  19. 19. satvikpendem||context
    You don't have to accept it but seems like that's what is happening. Humans just don't seem to have the capacity for long term collective action against individual interests. Ultimately that may be what the Great Filter for us ends up being, maybe it'd have been different were we a hive mind.
  20. 20. Timon3||context
    Or: humans do have that capacity, but our system is explicitly set up to give the most power to the greediest among us, and these greedy people in power don't have that capacity.
  21. 21. MachineMan||context
    Which means those greedy people don’t have power, but the illusion of power, and the positions at the top are gatekept by intermediaries that serve the one who actually holds the power.
  22. 22. Timon3||context
    I'm not sure how you arrive at "Which means those greedy people don’t have power". What is the "which" referring to?
  23. 23. bulatb||context
    On no other issue would this type of wishful thinking be accepted.

    If I pour some water in a bucket and come back to find it's all leaked out, and do this every day for all of human history and always get the same result, I don't conclude the problem is the water won't try hard enough to not leak out.

    The bucket has a hole in it.

  24. 24. sixtyj||context
    Law of conservation of energy can be applied here as well. So you can’t expect something else if you produce and consume more.

    I don’t dispute capitalism and democracy.

    Just trying to figure out what I (as person) really need.

    Every weekend travelling by plane just to experience something else?

    Ordering some stuff across the globe from Temu, Aliexpress just because it is cheap(er)?

    Eating e.g. tuna because it is healthy that had to be transported around the globe?

    Drinking wine from South Africa because I don’t like Californian? (Blind tests by Wine Spectator magazine confirm that even a sommelier doesn’t recognize cheap from expensive ones.)

    Global export-import statistics is staggering… just a few: all metals, honey, fish, vegetables from Spain, avocados from Peru, almonds from California, cheaper than local milk transported across Europe , bananas from everywhere you can imagine… supply and demand - a lot of people have a much more money.

    Vessel and plane trackers show so many vehicles moving around that I wonder how whales can handle this traffic.

    There is chemical and industry that is real spin doctors.

    (Almost) everyone wants to have house, car, cheap everything, travel everywhere. Those who can’t afford do everything to become rich.

    Wealth is good. Plundering to get more money not so much. And mankind plunders like there is no tomorrow. All the CSR, circular economy etc is nice but brainwashing and stuff for distraction so people could feel better.

  25. 25. noir_lord||context
    > I don’t dispute capitalism and democracy.

    I do the capitalism part, or more specifically what form of capitalism because there is a vast range between "society should work for capitalism" and "capitalism should work for society".

    I'd likely argue that on the whole capitalism in it's current form isn't working for society and the trend is towards that getting worse over time.

  26. 26. dns_snek||context
    > I don’t dispute capitalism

    But we should. This is a taboo topic but pretending that these consequences are either disconnected from capitalism or that capitalism is some natural law of the universe that should never be challenged is, for lack of a better word, delusional.

    These consequences are inherent to capitalism because people benefiting from it demand infinite growth and nobody is incentivized to care about the environment. People who care about it get outcompeted by those who don't in ruthless pursuit of "efficiency".

    We can try to regulate it to the point that people wouldn't call it capitalism anymore but the nature of a system where the only incentive is maximizing profit will always have a natural tendency to harm the environment, so it should be disputed.

  27. 27. MachineMan||context
    I personally don’t think either communism or capitalism will exist in 10 years from now. We are entering a period of total upheaval, where the very concept of a nation state has become obsolete. I expect global theocracy where robots and ai (incl nanobots) clean up the mess we made in this world, freedom becomes more limited, but abundance and security increases. There will be a renewed focus on community and human connection rather than the run away obsessive focus on materialism and innovation at a pace human beings cannot adapt to. Human labor, cognition, natural resources and policy have always been the elements that dictate whether a nation can develop into a first world country. Labor and cognition are respectively solved by robots and AI.

    Leadership by the Tokugawa shogunate saved the forests of Japan. Leadership saved the ozone layer. Leadership can save the climate, although civil war(s) maybe necessary to overthrow corrupt elites who put us all at risk.

    Earth has an immune system called the atlantic meridian overturning cycle. When meltwater dillutes the salt concentration too much, it collapses and creates an ice age. Short term catastrophe, long term it will be OK.
  30. 30. defrost||context
    > it collapses and creates an ice age.

    We're already in an ice age (there is ice at the poles). I suspect you mean this would make Europe cooler, but do nothing to reverse the trend of increasing global mean surface (land + ocean) temperature.

  31. 31. kuerbel||context
    They mean a glacial period, I guess... we are in an interglacial in an ice age
  32. 32. MachineMan||context
    Correct. This is all planned. Colossal Biosciences has already brought back the Dire Wolf and is working on the woolly mammoth. It is no coincidence that these are younger dryas animals, because they are expecting these animals to thrive in the near future glacial period. Don’t feel guilt tripped into causing this collapse, you have no control over it even though you can do some marginal things to reduce your individual footprint. Whatever needs to happen, will happen. AMOC collapse greens the desert. It also happens to be the region that dictates how affordable fossil fuels are and thus how much of the stuff is burned due to OPEC. If you are religiously inclined, that is meaningful.

    Edit: For reference: https://colossal.com/direwolf/ https://colossal.com/mammoth/

    you should look more into the wolf thing. they didn’t do that.

    Jury's vague on AMOC collapse despite the high bong appeal. Points for the furry weave.

    I think when people talk about stuff like this everyone realizes that the Earth itself will be a-okay in the long run (or hell even the short run), it's more that humans as a species are the ones that are going to go kaboom.

    We saw during the COVID lockdowns that a few months of no cars and drastically reduced oil usage in general how much things improved for nature in general, in fact. Earth will recover very quickly once we're gone, the question is more how do we avoid the "humans gone" part because we presumably want to keep the human species going.

    We're acting against our own evolutionary fitness function. Human nature is against human nature.

  39. 39. nielsbot||context
    Not sure why these reports always say things like "suggest" instead of "is".
  40. 40. defrost||context
    Because this is science, not religion.

    The thesis: Climate change is strengthening El Niño clearly uses the word "is".

    Everything else is evidence, both for and against the thesis subject to interpretation.

    Here it's "Something we can see in coral records correlates with what we'd expect given the thesis"

      The study doesn’t prove climate change is the culprit. But because the intensification coincides with rapid postindustrial warming and exceeds El Niño’s natural variability, the authors argue that human-driven warming is the leading explanation.
    
    These observed correlations may be directly or indirectly linked to the thesis, or (and this does happen) they may be an unrelated coincidence.

    As the weight of evidence in favour of a thesis builds, so does the confidence in the thesis itself.

  41. 41. phtrivier||context
    In this case, even the authors seems to agree that the finding is not "consensus-level" yet.

    That being said, consensus would not necessarily settle the thing.

    Even when the worldwide scientific community reaches a consensus and accepts using plain language (as in "It _is_ unequivocal that human influence has warmed the atmosphere, ocean and land" [1]), you still have a number of politicians begging to differ. [2]

    This is quite sad, so I've felt a bit guilty for enjoying the summer we've had in upstate NY. Local farmers seem happy even though spring was a bit wetter than optimal. The corn is looking very good and the apple crop promises to be large.

    I will not be surprised if we get a lot of snow this winter.

    And yet, every day, I see us getting removed further and further away from it.

    The western world has more or less come together to reduce emissions. If you look at US for instance emissions are down in abs terms. Not relative to gdp or per capital but total emissions. This holds even if you adjust for trade.

    The “problem” is there will always be independent upcoming nations like china and India that don’t really care to make sacrifices for collective goals. Their people are finally experiencing materially better lives and that comes w energy consumption.

    This will ultimately be solved by markets and technology. People 100y ago were concerned about horse crap flooding the streets and what solved that wasn’t some agreement to limit horses but the invention of the automobile. Same will happen here and it’s already beginning to happen

    > The western world has more or less come together to reduce emissions. If you look at US for instance emissions are down in abs terms. Not relative to gdp or per capital but total emissions. This holds even if you adjust for trade.

    It certainly is reduced per-production. China has double the carbon emission intensity of production that the USA has for example.

  52. 52. dumberquestions||context
    I'm not sure China's emissions can be considered a separate thing when the rest of the world relies on them for plenty of manufacturing. The West is still a massive emitter per capita.

    I'm thinking of the Ottomans capturing Constantinople. Very much paraphrasing: Since Ottomans had a massive cannon made with new technology. Since Constantinople hadn't hired the cannon inventor. Since Constantinople was poor. Since it was sacked by other christians in the crusades previously. So it was self afflicted by christians.

    One can see the climate crisis like that. Only global accords work, otherwise self-limiting CO2 is mostly sacrificing one's economy while others do better. USA will block all international climate accords. Because the president and half of politicians acts like climate change is not real. Because a whole party thinks that. Because voters think that. Because the media tells them that. Because the media treats fossil company propaganda like science. Because it's so cheap for a handful of companies to corrupt media or politics.

    What is the epistemology of the majority of voters... scandals, conspiracy theories, UFO:s. What shows on TV or on your feeds. I assume it's child's play for some non-western actor to cause constant infighting in the west, causing billions in economic losses or destruction of alliances. For whole planetary level issues, who's the opponent, working in the shadows? Maybe, after all, the aliens are already here...

  54. 54. jdw64||context
    With climate change, it seems like poor people will die faster from 'climate poverty.' Science clearly points to human-caused greenhouse gas emissions driving climate change, but certain groups frame it as just another natural cycle of the Earth.

    When I was younger, I learned that science was something pure. But as I've grown older, it seems like science is really about how it's used—and who gets to use it.

    The truth is, the more a developed country is positioned at the consumer end, the more inescapable these problems become in our lives. Our world relies on outsourcing the production of manufactured and consumer goods to developing nations. But separate from that structural reality, vested interests refusing to acknowledge their faults is an entirely different issue.

    Furthermore, I disagree with the radical ecological claims in the link. Humans might be developing technology that ends up destroying the public commons we call nature. However, I firmly believe there must be a better path to coexistence.

    Greenhouse gas emissions also coincide with the greatest poverty reduction period in human history.

    Climate science is pretty close to a "pure" hard science. What's not pure are the sloppy geopolitical and socio-economic predictions derived from it.

  58. 58. goatlover||context
    Do Greenhouse gases also coincide with the greatest poverty production prior to that? The human population exploded after the industrial revolution.

    Was snorkeling this winter in some tropical waters in asia and noticed how dead everything looked, compared to the same place 20 years ago. When I asked about it, the locals said "It's all from the same El Niño in 2015. It all died the same year".

    So there are vast areas of Coral that used to be fantastic in 2014 and which is dead since the 2015-16 season. It takes many decades to grow back if it ever does. And now we're about to have another.

    I think there's a certain cohort of people who, quite literally, just want to watch the world burn for whatever reason, be it greed or simply misanthropy. Unfortunately they're the ones that seem to grasp for the reins of power the world over. It'd probably help if we didn't allow boomers any power whatsoever, considering they're not the ones that have to live with the consequences of their decisions and they hardly seem wiser than most.
