          The dinosaurs got wiped out by a catastrophic meteor impact (or so we think). This is different. We are changing the climate at an accelerated pace that’s never been seen before. Species adapt to things over time. You can’t adapt if the weather isn’t stable, and things dip between super hot and super cold, or visa versa, they stay super hot or super cold. We have other examples of worlds like that in our solar systems, and they are dead worlds.

            There have been at least five major mass extinction events in the history of this planet. What will be after us in the future won’t look like it does right now, but right now doesn’t look anything like it did before any of those five events either.
            As the saying goes, life finds a way. We just won’t be around to witness it.

            Permian Triassic extinction event is the one most similar to current situation.

            The level of atmospheric carbon dioxide rose from around 400 ppm to 2,500 ppm with approximately 3,900 to 12,000 gigatonnes of carbon being added to the ocean-atmosphere system during this period.[22] Several other contributing factors have been proposed, including the emission of carbon dioxide from the burning of oil and coal deposits ignited by the eruptions;[27][28] emissions of methane from the gasification of methane clathrates;[29] emissions of methane by novel methanogenic microorganisms nourished by minerals dispersed in the eruptions;

              We know what the climate was like in the past by looking at layers in the earth, tree rings, even carbon dating can sometimes given evidence of how the composition of the atmosphere was in the past. There a lot of neat chemistry that we can use to learn what composition the atmosphere and climate had. Obviously there is some amount of error in models, but we do know.

                I think there are a lot of errors in the models. Tree rings can only go back so far because most of the early trees are now coal. And trees, while they do live for a long time, don’t live forever. Fossilization is rare and I don’t know if we can get weather data from fossilized tree rings. Carbon dating is useful for organic matter up to 60,000 years ago. The other methods used to determine what the atmosphere was in the past include studying ice samples from Antarctica but that’s only good for the time Antarctica froze till now, it was tropical at some point. Since most scientist think complex life has been around for 500 million years I don’t think we can really say we know exactly what the climate was like and how it changed anywhere past a certain time period.

                  I think …

                  That’s the problem. Thinking without actual evidence to back it up = your opinion. Having an opinion is fine. But in a discussion such as this you need to come into it with factual data.

                  It’s the equivalent of showing up to a gun fight with a knife, believing you have a chance of winning.

                  Tbf, the average billionaire negatively impacts the environment on a level that is hard for people to comprehend. Most people are really, really bad at understanding volume and scale. Like the difference between a millionaire and a billionaire.

                  Example: In 2023, 50 of the world’s richest billionaires took an average of 184 private jet flights per year, emitting as much carbon as the average person would in 300 years. Elon Musk’s two private jets alone emit 5,497 tonnes of carbon dioxide per year, which is equivalent to 11 average people’s emissions in their entire lifetimes.

      Humans are pretty resilient. Adaptable to any climate, even the mess of a climate we created.

          I’ve seen some of the same estimates. I settled on 2K because that’s what is estimated to have survived the To a supervolcano. Or rather the non-African population that survived.

    So, what does this all mean for us? It means we have even less time to get our act together. Reducing emissions isn’t just a good idea — it’s crucial.

    I don’t think this will motivate countries to dramatically increase emissions reduction efforts, but I think it will motivate countries to begin geoengineering. Geoengineering is cheaper and easier than rapid emissions reduction, and the results are more immediate. Yes, it doesn’t solve the core problem, which is the concentration of GHGs in the atmosphere, but it treats the symptom, albeit temporarily. Why put a lot of time, money, and effort into fixing the core problem when you can spend comparatively less time, money, and effort just treating the symptom? Then you can just pretend the core problem doesn’t exist and go about business as usual.

    Edit: sorry, I should have added the /s.

          I’m way more worried about mean sea level raising above much of our lower elevations. We’re already raising dikes, also making them wider so they can easily be made even higher in the future, accounting for the most pessimistic of projections, but you can’t really keep water out with dikes when the sea is pushing groundwater up. You can do it like the Dutch but if their pumps ever fail they’re royally fucked. Electricity, availability of huge amounts of energy in general, is not something you want to rely on in these matters if you can avoid it.

          We’re probably going to end up with large areas of salt march interspersed by towns on mounds and a couple of lakes to construct those mounds, the dikes only making sure that they’re high, not low, salt marches – not elevation-wise but regarding how salty they are, how often they get flooded. The alternative would be to give up the marches completely and knowing our Frisians no that won’t happen. Barley and sugar beets are naturally salt-resistent, btw, more plants are getting bred for it. Not to mention tasty veggies that allow you to retire your salt shaker

          tl;dr: Wat mutt, dat mutt. Imagine Sisyphus happy.

        As someone who whe experienced both-ish, I tend to agree. There is a point where you just get sick when it’s too hot and humid and it’s way worse than being cold. Your system just shuts down and you feel so bad, and if you don’t get away well you die.

          Heat pumps work at >100% thermal efficiency.

          Air conditioners dont.

          An air conditioner is a heat pump… That just works in one direction. It uses refrigeration just the same.

          They both rely on creating a thermal gradient between two heat exchangers. And they are both negatively affected by extreme temperature gaps.

          The heat exchanger facing outside with a heat pump must be colder than ambient temperature by a reasonable margin. The opposite goes for an AC. These qualities break down in extreme ranges for typical hardware.

          This also, as expected, reduces the efficiency.

      China is better in implementing countermeasures than especially the USA (also looking to the dark future ahead) but if they would take it seriously they would need to do quit a bit more especially driving something like a global CO2-tax, but AFAIK they were the ones blocking such measures (not that other nations are much better). THIS would be effective.
