Temperatures above 50C used to be a rarity confined to two or three global hotspots, but the World Meteorological Organization noted that at least 10 countries have reported this level of searing heat in the past year: the US, Mexico, Morocco, Algeria, Saudi Arabia, Kuwait, Iran, Pakistan, India and China.

In Iran, the heat index – a measure that also includes humidity – has come perilously close to 60C, far above the level considered safe for humans.

Heatwaves are now commonplace elsewhere, killing the most vulnerable, worsening inequality and threatening the wellbeing of future generations. Unicef calculates a quarter of the world’s children are already exposed to frequent heatwaves, and this will rise to almost 100% by mid-century.

    If the world was warming even faster than scientists thought it would, seemingly jumping years ahead of predictions, would that mean even more crucial decades of action had been lost?

    Yes. Yes it would.

      Rivers in Alaska have been running bronzish-orange… because the permafrost is melting.

      The ‘perma’ frost, is melting.

      That has huge amounts of methane locked up in at.

      Which is 8 to 80x more effective at being a greenhouse gas than CO2.

      And also ancient bacteria that could cause previously unknown kinds of diseases in wildlife and possibly humans, they now may or may not be seeping into the environment.

      We have already had a consecutive 12 months at or above 1.5C global average temps, as of last month.

      Shit’s looking pretty bleak.

        And thereby eliminating a whole bunch of other species than just humans as well.

        Although I’m totally in for the occasional misanthropy, I don’t like seeing it as “just a fever” anymore as too many species will go down. Life will probably persevere in the end, but so will probably a bunch of rich shitpieces, who are significantly responsible for this fever in the first place.

          Our world has gone through many life cycles in the past. At the beginning, was darkness, at the end, probably the same (unless it’s a Futurama time cycle).

          The earth will continue on and life will find a way. At this time, we, as humans, have screwed the pooch and now the pooch will screw us. We used the earth and culled it’s resources. We are taking no consideration to the world around us, and instead focus on ourselves alone.

          All of the movies about aliens are true. Humans are selfish, greedy, parasites.

      And I’d be ok with this. I see that humans are failing the test. I think it would be totally fair for us to take some really huge losses as a consequence of our collective hubris. But the thing that makes me sad and angry is that we’re taking down everything else with us.

      There’s such a huge diversity of life, basically just minding its own business in a totally sustainable way. It’s been like that for billions of years. More than 1,000,000,000 years. But then humans work out that burning stuff is an easy way to do mass-production, and in less then 1000 years things start turning to shit - for everyone. That’s so unfair. If it was just our own house we were burning down, I’d say its fair. But we’re burning down the whole world. We’re already causing mass extinction, and by all predictions it is going to get much much worse.

        Other organisms and natural disasters do that, too. Ice ages, meteors, waves of diseases. The difference seems to be we have the consciousness to predict consequences, then decide whether to embark upon a path of behavior, or continue it when latent consequences emerge. I guess the question ends up being whether the course chosen is “natural,” and how can we know, since plenty of organisms kill the host, while also surviving and even propagating? Then observation also changes the behavior of things. And we don’t kill everything. Just whatever life is left continues to evolve in expected and unexpected ways.

    The reason nothing will be done is because the only realistic option we have to save our planets ability to sustain life is economic degrowth.

    We don’t have enough of the minerals we need to go fully nuclear or renewable and even getting close would use up vast amounts of the very same energy were looking to save in the first place.

    As the record levels of equality directly after ww2 showed, economic degrowth due to nearly all the men being at war, only results in the loss of the super rich which is why they’ll never allow economic degrowth.

    We all work too much, produce too much and pollute too much. Worse, we’re all forced to produce the very wealth thats used to force us into wage-slavery and kill our planet.

    The answer is and will always be the strategic refusal of labour, above what we need to survive and have a good quality of life. This, by default, will result in economic degrowth.

    Want to sit around and do nothing to save the planet? Well, now you can.

      Uranium is extremely common on Earth. What minerals are we lacking to go nuclear? If you were arguing that we need to switch the type of reactors we use, I could see that. A lack of fissile material isn’t an issue.

        If I remember correctly, we don’t have enough of it to go fully nuclear with our current energy demands. More so, we’ve mined nearly all of the soil thats anything above 0.02% uranium. As such, not only do we not have enough on the planet, getting it and refining it would almost defeat the whole point of doing so in the first place.

        It is a problem in that there might be plenty of it but that doesn’t mean there’s enough.

        Just to be clear, I’m not saying we have to go back to the stone ages. Its just that we can’t afford the super rich anymore.

          Pretty sure there’s enough weapons grade plutonium to run the US for 100 years in decommissioned nuclear weapons alone.

          I think 100 years is enough time to build pumped hydro storage and renewables like solar/wind.

            The problem is that there a major, major shortage of one of the isotopes needed to re-enrich weapons grade uranium (pu 238). Thats before you get to the vast energy inefficiency of doing it which isn’t a problem, if you’re just decommissioning them anyway and you don’t care about energy consumption. However, in this instance, you would need to worry about energy consumption as well as the isotope there won’t be enough of to convert even a fraction of it.

            Again, even if you had 100 years, there aren’t enough of the specialist minerals needed for hydro storage and renewables.

            Essentially theres" a hole in our bucket."

            The only answer is degrowth.

                I’m not saying it can’t be converted or that the amount couldn’t, if refined, potentially fuel America for a number of years. So, I’m not sure what the link was for. I said its not feasible, due to the inefficiency of doing it on mass.

                What about the energy transition materials like lithium, nickel and cobalt? We don’t have enough of those. All the windmills in the world won’t help, if you can’t convert motion into electricity.

                Even then, copper looks to be facing an impending shortage. More still, refining enough silicone to supply the world with and keep up with increased demand of energy would have a colossal carbon footprint, almost big enough to cancel out the benefit. You’ll have to start refining soil thats 0.000000000001% silicone before you got even halfway through. Yeah, we have loads of these things but getting enough of it, in a pure enough form, to power the whole world simply isn’t realistic.

                We can’t keep up with the speed that we increase our energy usage with the resources we have on the planet. Its a circular problem with only one solution. I’m not saying we have to go back to the primitive. We just have the treat the planet as though its resources are finite.

                They’ll sell us any flavour of distraction other than “work less, do less, slow down and enjoy life more.” Whatever way you cut it, its the only answer.

                  We literally don’t need any of those. Grid scale storage I don’t think has used Nickel and Cobalt for some time, as the best way is to use Lithium Iron Phosphate batteries which need fewer replacements (longer cycle life) and are less volatile (explosive). Sodium batteries remove the need for even Lithium. Sodium is many times more abundant btw. As bad as they are Lead Acid batteries are also an option, as well as many other battery technologies made with less rare earth materials. Heck you could just do pumped hydro and not worry about batteries at all.

                  You also don’t need any of those materials to make electricity from motion. A generator is a fairly simple device needing only coils of wire and a few moving parts. Some need permanent magnets but even that isn’t hard really. Storing power was always the problem, not making it.

                  Likewise current reactors are a joke in terms of fuel efficiency. Basing any estimate on current reactor technology being used is kind of silly, as we already know we can do so much better. The majority of earth’s nuclear fuel is in fertile materials, not fissile materials. We have known this for a long time by the way. Decades ago countries like the USA and Japan were doing research into reactors using U-238, more than 100 times as abundant as U-235. It has been demonstrated that breeder reactors for Plutonium from U-238 are feasible even 50 or 60 years ago. The reason we don’t do this is because U-235 reactors were determined to be cheaper, and probably safer. I think sacrificing some safety and cost is necessary when up against something like climate change. With modern technology I am sure safety issues could be reduced or eliminated. Likewise Thorium is a thing, but that’s more experimental than U-238 to Plutonium technology.

                  If we are talking about solar panels: just don’t. Solar panels are mostly glass and silicon. I believe some rarer materials are needed to make them as efficient as they are now, but that doesn’t mean they are actually needed. In fact why bother with solar panels at all? They aren’t even the most efficient way of turning solar power into useful energy. Solar systems that work using mirrors to heat molten salt have their own energy storage built-in, and don’t require exotic materials, and are more efficient anyway. They might require more investment, or be more complex to deploy, but overall they are a great option.

                  Degrowth might be necessary in the short term. Long term wise though humanity very much has room to grow further. We haven’t even talked about mining the moon yet, and if we can’t do that we are very much screwed anyway. Being dependant on one planet is horrifically bad for long term survivability. You think climate change is an extinction level event? Try a gamma ray blast from a pulsar.

                  All you’ve really demonstrated is that you don’t understand technology specifically renewables and nuclear. There is a real concern with lack of rare materials, but not for renewables. The real issue is computers. Modern computers and especially smartphones need a lot of rare things. So constantly replacing your smartphone might not be practical anymore, and things like battery life and processing speed might actually get worse for a while as we are forced to use alternative materials. Not really a huge deal in the scheme of things though.

                  Also thinking the rich elite are the only people consuming things at an unsustainable rate is hilarious. They use more resources per person obviously, but the number of them is also really small. If you actually looked into it you would probably find that lost of the consuming of resources is to support the lower and middle classes. Don’t get me wrong oil executives are a real issue because of how they effect government policy and the behaviour of the rest of society. They do deserve a significant share of the blame. Not every rich person is an oil executive though. Having ultra rich people around is bad but this isn’t the reason why.
