Did it actually say it will DOUBLE the CO2 concentration? Definitely past the point of no return. I guess us millennials WILL actually see the worst climate cha

  In my home town back in Russia they now easily grow the stuff of my unreachable back then in USSR childhood dreams - apricots, cherries (the large sweet ones). The children there though don't do backcountry skiing like i did 40+ years ago because there is no snow these years there. And Russia pumps out fossil fuels without any care. They feel that things like opening of the Northern Passage and more agriculture on the previously hardly suitable lands are great for their future (they aren't climate change deniers, they are believers. Like everybody else there, I was taught about climate change as a clearly established scientific fact in the 6th grade in 1985). So, until somebody brings out 10+ aircraft carriers and enforces global climate accord, i don't see any progress happening here.

      I don't think Russia is unique here. I was talking about it because i know it. i can't talk this way about say China or Argentine (or basically any other country except may be US where 25+ years of residence give me some knowledge to talk about).

        FWiW and with no judgement attached .. Russia will likely be benefited more by AGW climate change than many other countries. Already people anticipate vast cattle ranches, cowboys and and rodeo clowns across Siberia.

    I see the major problem isn't that there will be just warmer temperatures, but that the climate will become unpredictably changeable. For the moment, it can be beneficial for agriculture in some areas, but it's likely that our global food production will have to massively change to take into account times of drought and flooding that will destroy crops in some areas. Whereas now we can just grow crops in fields, we may have to grow food in greenhouses just to be able to provide the plants with consistent growing conditions.

      There are a lot of variables here, and one is the sun. The other is time. We can certainly, even without genetic engineering breed crops more suited for shorter growing time frames. There are a lot of corn hybrids, some mature fast, others far slower. Some require more sun, others less. For example, some of the faster growing varieties only take 60 days to mature, others 100+. But here's the thing. Those are 60 "good weather" days. As in not too much cloud, not too unseasonably cold or warm, reasonable amounts of rain and water, and so on. As corn takes time to grow and mature, it doesn't matter how much sun you throw at it, it still only grows so fast. Up North, even if it's warmer, you still need enough sun too. Compressing the sun around the summer solstice doesn't help. Giving it 22 hour long days of sun doesn't just magically make the corn grow 2x as fast as an area with 11 hours of usable sun. And the spring is still "rainy season". Some crops can't take too much rain. Where I live, a local farmer grows traditional yellow corn, as some prefer it over newer, 'peaches and cream' hybrids. But some years? It just doesn't mature. Too much cloud, or other inclement weather (too hot, too cool, to much sun, etc) and being further north means there is little wiggle room in the growing season. I guess my point is, Northern areas will require only certain crops. That's fine of course, and it will indeed feed people, but some crops won't be on the table. One thing that may have already helped Russia, is the extensive work the Soviets put into breeding crops to grow further north: https://solar.lowtechmagazine.com/2020/04/fruit-trenches-cultivating-subtropical-plants-in-freezing-temperatures/ https://solar.lowtechmagazine.com/2020/04/fruit-trenches-cul... While I do not doubt the weather is more mild in Russia these days, it's also quite erratic. At least it is here in Canada. Some winters mild, then bam a winter of "old". So I wonder if the above breeds have given Russia a leg up on taking advantage?

    > So, until somebody brings out 10+ aircraft carriers and enforces global climate accord, i don't see any progress happening here. If we look at the enforcement and outcomes of former climate action „plans“ this is unfortunately a valid option.

  The keyword here is "Long term" I suppose, that can mean anything. I couldn't actually find where this claim comes from. The referenced paper doesn't seem to say anything about doubling CO2 concetrations.
  • SwtCyber 1y ago
    Still serious, but yeah, the headline might be running ahead of the data a bit
  • bertili 1y ago
    If it "Short Term" becomes obvious that we are past the point of no return it doesn't really matter if "Long Term" units is 100 or 1000 years. Most future living things will be suffering. There could have been more future things than past things to enjoy this beautiful planet.

    In climate science parlance it means it's a conservative guess and will likely happen faster than anticipated.

        30 years ago I learnt in school in chemistry class that earths oil reserves will be used up in 30 years.
        • panstromek 1y ago
          That was true back then though. It boils down to how oil "reserve" is defined, which is all about oil we know how to extract.
          • lynx97 1y ago
            It didn't turn out to be true though. "True back then" seems like a weird way to phrase "wrong".
            • panstromek 1y ago
              No, it wasn't wrong, because "oil reserves" are defined as: "quantities of crude oil and natural gas from known fields that can be profitably produced/recovered from an approved development", which means they change over time, when we find new oil or develop new technologies. And that's also what happened.

  It's fine... Gen Alpha will figure it out by asking AI.

  > Definitely past the point of no return. We don't really know at what point that is. It's probably something we can only identify in hindsight. I find it bewildering that our approach is basically FAFO.

  The timeline isn't some far-off sci-fi scenario anymore. Millennials and Gen Z are basically the frontline generations

  We've been past the point of no return since the mid-90s.

  At double the current ppm it'll start to impact our cognitive abilities, we're not doing much about it now but wait until the average joe drops another 10 IQ points...
