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.

    Late or not, we have to do all we can to stop runaway warming and ecological collapse. We know corporations and populations won’t do anything voluntarily. That is why legislation is the only way. EU is taking the lead on this. I’m hoping world countries will follow.

      A lot of companies won’t even allow remote work which would put a huge dent in commuter related pollution. Will that fix everything by itself? Nope, but it’d be a step in the right direction.

      But they won’t even do THAT. This one little thing that’d be better for a lot of people and reduce car dependence related pollution for people in areas with little to no public transit access.

      I have a hard time believing the US will ever catch up to green initiatives since corporate lobbying pays corrupt assholes more…

      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.

        I can at least alleviate your worries of ancient bacteria.

        Even our weakest antibiotics could wipe them out as they have evolved zero resistance to it. That’s assuming they can even infect humans in the first place.

          Have you ever looked up how long it takes for bacteria to evolve resistance after exposure to an antibiotic?

          2-3 years… Yeah…

          More concerning is a virus in my opinion. Jumping species is common and it’s the novelty to the immune system thats the danger. How much damage would an influenza strain from 3-4000 years combining with modern strains cause?

            If that was all there was to it, no bacteria would be affected by antibiotics anymore. And yes, they’re less effective, but it’s far from an obsolete tool. We just have to be smarter about using them.

            Horizontal gene transfer is a thing amongst bacteria, so yeah, possibly (except in no way whatsoever like a wolf dog hybrid, entirely different mechanism).

            There’s also ancient viruses, which are much more terrifying and probably have a better chance at having been preserved.

            That’s not how bacteria multiply. There is horizontal gene-transfer, but that would be a very slim chance.

            No ancient bacteria aren’t the problem, multi-resistant strains that have already evolved and are evolving in our clinics are the real problem, some bacteria that haven’t been an issue for quite some time, because our antibiotics simply killed them, have now developed resistances and are suddenly becoming deadly again.

            E. Coli, Staphylococcus aureus and Salmonella, some of the most prevalent bacteria in humans are rapidly becoming multi-drug-resistant and resistant to desinfectants like chlorine. These superbugs already account for a shockingly high number of deaths in healthcare facilities and the situation is only getting worse as more and more countries use increasing amounts of antimicrobials, kickstarting microbial evolution into overdrive.

                Contraceptives exist, as do abortives in case the first ones fail.

                The only two reasons anyone would have kids as the world is going are ignorance, or a sadistic desire to watch said kids suffer. In which case the fun is certainly not consensual (or shared) on the victim’s part.

          I haven’t seen anything from climate scientists that agrees with that level of doomerisim. They want to keep fighting against every 0.1C of warming we can, because that’s a worthwhile fight. Succumbing to climate nihilism is unhelpful, unscientific, and a self-fulfilling prophecy.

            With the release of this much methane this fast, we might as well be out of equation at this piont. And by this fast, I mean on a earth’s climate timescale, not a human one. How could we possibly stop what is already snowballing? We HAD our chance to stop this and we did nothing. It is too late now to do anything but survive the new world we have made.

      The issue here is that leading climate scientists are saying our current models aren’t accounting for the actual reported climate, and they’re not sure why it’s off. They’re hoping the new NASA climate program will provide more data for the causes. Currently it’s not explainable by CO2 emissions, sulfur from boats, volcanoes, etc, all of which when factored in still don’t account for more than 90% of how much warmer it is getting.

      Yes, human caused global warming is real and happening. The big concern right now is it’s happening much faster than expected and we have no good, proven theory as to why. That’s a problem.

      This isn’t just climate deniers though - even those that were expecting significant climate shifts are still seeing higher than expected. This isn’t “huh, things are getting hotter, who would’ve thought?” This is “we knew it would get hotter, but we predicted it would take longer.” We thought we were fucked, but we’re actually double fucked.

    The answer is aluminum roofing! I was a the beach a couple of weeks ago and you just couldn’t step on the hot magma for any amount of time. But if you sat down on the shadeless aluminum benches provided by the idiots at the government, you were welcome to the best feeling of freezing your ass off while searing your nuts off. It’s aluminum, we know it can reflect like 90% of all incoming light including heat and UV…and Wi-Fi. But I much rather have antennas that allow phone communications than to have to run the AC non stop even when the house has more insulation than my fridge.

      Aluminum oxidizes and no longer reflects after long term exposure to moisture. It would have to be painted white, which is really no different than current metal roofing.

      Which does bring up a good point though… all we need is some really environmentally friendly and long lasting white paint (that doesn’t get dirty) and we could easily slow down climate change. Unfortunately white paint gets dirty real quick and the dirt absorbs radiation the same as a dark paint.

        Anodized aluminum absorbs some heat, but that’s only one single light pass. Or well two passes. But that’s way better than aluminum with white bird poop on it which is easily cleaned. Clear anodized aluminum or white reflective aluminum would be quite superior to anything out there.

        But it isolates radiated heat. You’ll have to pump heat built up inside. But also, aluminum radiators pointing upward can help reduce climate temperatures similar to the way trees do. Trees absorb the heat and shade the ground. These would shade and reflect heat creating a cooler area underneath if heat is not actively being generated…no humans or computers or pets. So not a silver bullet but just makes me so puzzled to see people using tar, which pollutes the ground, and steel which perfectly absorbs heat. No, the best solution is to use aluminum.

          steel which perfectly absorbs heat. No, the best solution is to use aluminum.

          Aluminum is far more thermally conductive and makes both a far better radiator and absorber of heat. Ultimately it’s a coating that does the absorbing though, as shiny metal reflects IR regardless of the material. Source: I work with this stuff

          Light coloured or reflective roofs do make sense though and that’s why traditional homes in most hot climates are painted white.

            Yes. Ideally you want a sandwich aluminum -steel - aluminum. But that’s not ideal. Sometimes you see this in heat shields around exhaust systems. But nothing beats experience. The fact is that if you put a sheet of tar roofing, a sheet of steel and a sheet of aluminum under the sun, the tar will get melty, the steel will get fucking hot and the aluminum will be nice and cool to the touch. Sure you can spray aluminum onto the steel or the tar but it won’t be as efficient and you won’t get the reflective properties that aluminum has. Remember the wavelength of heat is past the 0.1um and it’s up to 100um, so most coatings are not that thick and most roughnesses are not that rough locally where it matters. Machined aluminum for example will have a local roughnesses less than 25um, sometimes under 1um.

      Living and dying are the same process. You can’t be born without dying. You could say biology condemns us all - very loosely - to a cult of death, as we must all participate.

      Capitalism is worse than that. Capitalism is an ideology of exploitation. I’m fine with dying, it’s my fault for being born. I don’t see why I must submit to exploitation while I do, temporarily, exist.

                i mean you probably influence them, but much like dreams, are they really representative of anything other than your mind left to its own devices?

                Human conception may start at the sperm race, but human consciousness doesn’t begin until a few years into childhood, so at the end of the day, who knows.

                  Can thought be considered a process that begins after being affected by an external stimulus? And without prior experience on which to base our response, we can only react according to the conditions set by that stimulus?

                  So is it truly we who control our thoughts or are we just acting in a predetermined set of reactionary impulses based on the accumulation of our personal experiences and gained knowledge over our lifetime so far?

                  We who are so easily influenced into outrage by trigger phrases specific to our fears or spurred into action by resonating soundbites promising our desires, are those our thoughts or are they just the mind left to its own devices?

                  I really don’t know. But it’s probably some food for thought in a way.

    Its cause none of these systems are static or by themselves in a vacuum. There are feedback loops in all parts of our environment. Its not a coincidence that the temperature started to accelerate after the recent series of MAJOR volcanic eruptions in the many parts of the worlds oceans. Throw in the absolute monstrosity that is human industry and well the feedback there is more heat from industry combined with greenhouse gases means the the heat in those areas rises. What does heat do? It rises and moves outwards until it reaches equilibrium. Where is it cold? The arctic and antarctic. What’s happening in those places recently? Oh yeah huge spikes in temperature that are causing shifts by over 40-50 degrees Fahrenheit or about 8-10 degrees celsius. Sure it’s technically still freezing over the arctic and antarctic for portions of the year. However the arctic has, for the last several years during summer, been almost entirely ice free. The North fucking Pole is ice free during the summer time. That’s fucking insane. Everything feeds into everything else with our environment and climate.

    Until more people in power actually understand these facts, we are all going to suffer needlessly.

    There are also some comments about aircon not being a good answer if solely relied on, including:

    One of the key effects of heatwaves, which send demand for electricity soaring and cause extreme storms that stress electrical grids, is to cause blackouts. Blackouts mean no more air-con. A recent study suggested a blackout lasting just two days could hospitalise more than half of Phoenix residents and kill 12,000, mostly in their own homes. This is why the author Jeff Goodell warns of a “heat Katrina”: you thought the hurricane in New Orleans was bad?

      Further, what happens when everyone knows the power isn’t coming back and instead the roads out of Phoenix all get backed up and people die in the heat of their cars trying to escape the heat of Phoenix. Because heat can kill a lot of vehicles, and a lot of people have ill-maintained vehicles, meaning roads being completely blocked from escape can happen fast.

      I really think Phoenix will become the first mass casualty event from climate change in the USA.

        That’s one of those nightmare thoughts - when the power goes out, what do people usually do for a while? Wait for it to come back on. Someone is coming to fix it, right? Much of modern society is built upon such assumptions, and it mostly works. So I think you’re right for some, but many would perish at home, trying to outlast the day (and what if the night doesn’t cool?)

            Water also disappears. At some point water is being pumped by a power source. I suppose that’s more when people get driven out, by hunger and thirst than by just curiosity or a plan. So much easier to leave before things go bad, but like Katrina showed, mobility is a class thing, some people can’t leave like that.

        Realistically it’ll be when people can no longer insure their homes when we see the first mass migrations. Florida is already at the point where only state insurance will cover hurricane prone areas, and it sounds like that currently costs $7k/year. Anyone have any bets for if it’ll be the southwest suffering more frequent more severe fires that gets it first or Florida and neighboring states from more severe hurricanes?

          Most people buy the cheapest car batteries they can get. As a Floridian I can tell you, the heat destroys these things faster than most people realize. Everyone is already strapped for cash so they’re going to be driving around with batteries that barely start their car for months before it finally leaves them stranded.

          Car radiators have fans. They can idle indefinitely. You’re more likely to eventually run out of gas.

          Edit: oh you mean because of the heat. I don’t think that’s going to be an issue, ambient temp is still going to be far below the roughly 200°F of an engine.

            This assumes a car with a working cooling system. How many people have old cars with bad head gaskets or a radiator leak and “just fill it with water” and not fix the problem, only to find that pure water isn’t enough, as modern cars will walk up and down from 185-235F, which will blow steam before the fans kick on. They never noticed because they only drove a few miles a day, not long or hard enough to find out there is a real problem and not a nuisance.

            Do you not live in the USA? Do you not realize how many people are driving around old beaters that can absolutely get overheated in such an environment?

            In my hometown more than half the driveways are filled with multiple beater-ass cars, most of which don’t work and are just sort of rotting. They just keep adding new ones by buying more shitty vehicles that die quickly and doing the same cycle over again.

              I do live in the USA. I’m pretty sure that no parts of the US are predicted to remotely approach 200°F air temperature.

              I actually drive a beater myself. But if the coolant pump or radiator fan aren’t working, you’re not going to be driving it very far, regardless of air temperature.

        That’s when it becomes Rita as opposed to “heat Katrina”.

        For folks who don’t remember/know about Rita because they didn’t live through it, less than a month after Katrina a record-breaking cat 5 hurricane was heading for Texas. Everyone still had Katrina on their minds and panicked. Millions of people (literally estimated as 2.5–3.7 million) evacuated, or tried.

        The highways out of Houston came to a total standstill. About 100 people died before the storm even hit land because of the evacuation. And then the hurricane itself was nbd; the evacuation was literally the worst part.

      I keep an old evaporative unit in the shed just in case. It only needs 70 watts and can thus run for quite a long time off a car battery or similar. Add a basic camping solar panel and you’re more or less set for the day as long as you have water and don’t live in a really high humidity place.

      Frankly, I am amazed it has not already happened in Houston, Dallas, San Antonio, or Austin. The power grid here in Texas is a disaster and the weather conditions are unforgiving. At least in the desert you can do evaporative cooling. That doesn’t work where its hot and humid.

        It has. Some weak ass cat-1 hurricane killed like a dozen people in TX earlier this year. The winds didn’t harm anyone directly but it knocked out power for a few days in places. That’s all it takes when temps are well above 100F.

          Yeah, I was in that storm. We were without power for 3 days. Fortunately it was not over 100f that during that stretch but It would have been so much worse if it had been. I personally know people who were without power for almost 2 weeks after it came through. Centerpoint was negligent in maintinging their equipment, right of ways, and getting their crews where they should have been.

          I get downvoted for asking for cars with manual roll up windows because spending electricity on rolling up a car window is negligent when its easy as fuck to do by hand.

          But if you add up all the electricity used since automatic windows were invented, power used to roll up and down windows, in aggregate its no small amount. It adds up.

          But nooooo manual roll up windows is a step too far.

        Wait really? Do you mean by the electricity generation or by a refrigerant process?

        I know those processes are inefficient and create overall heat in the system as they can’t create cool but only push heat, there should be no green house emission, just heat generation.

        Are you saying extra heat will stay in the atmosphere? That’s not good but it’s not the same as carbon which allows heat to build up.

          The power used by AC is responsible for ~3% of global emissions. I can’t find data about the impact of refrigerants ATM, but I assume it’s significant because of their extremely high “global-warming-potential.” I’m guessing a significant amount of emissions come from the manufacture of refrigerants, and a significant amount of refrigerants leak out of systems when they fail (or are improperly disposed of).

      oh it’s much worse than that. not that it isn’t also that and them doing that isn’t the reason we didn’t get started mitigating this shit seventy years ago when we wouldn’t have needed substantial sacrifices.

      see, climate scientists are scientists. that means they can only announce what they KNOW, what they can be very confident in, what IS in the data.

      the thing about climate change is; it’s full of unknowns, most of them bad. so they can’t say “we have had this many unknown unknowns pop up and fuck our shit up, and expect (range of numbers) more”, because that’s predictive, and it’s useful, but its not SCIENCE, because science is inherently a very conservative bedrock-of-knowledge try-not-to-give-permission-to-fuck-up paradigm of knowledge. that’s not a flaw generally, it’s why we can trust it and why it’s hard to compromise, but generals and combat sports athletes do not choose their actions scientifically-it’s too fucking slow, and they would all fucking die/get punched in the face and lose literally every single time.

      so while they have calculated the known dangers of the path we’re tumbling down, they can’t really include the assumption that there was a military base here during a civil war 20 years ago, and both sides in that conflict really liked land mines. they can only point to specific mine fields they know about, even if that’s way less than any other site that was involved in that conflict.

      so however bad a climate scientist says it’s going to be, dude, holy shit, it’s going to be so much fucking worse. however much time they say we have, we have less than that. how much worse? how much less? no fucking clue.

      no way to know unless we sit on our asses and let it happen, at which point everyone dies.

    The new evidence that Greenland lived up to its verdant name in the not-so-distant past may represent an exciting scientific breakthrough, but it also heralds ominous possibilities for the future of humanity. Present-day atmospheric carbon dioxide levels are higher than they’ve been in millions of years; evidence of an ice-free Greenland in the more recent past means that it could take even less warming than once expected to deplete the continent’s all-important ice sheet. The frozen stronghold that covers Greenland contains enough fresh water to raise sea levels by 23 feet — a staggering volume that would reshape coastlines around the world.
