    The solution to global warming, then, is clearly to just set up a massive ring of fans all pointed in the same direction in a ring around the North Pole, to keep the jet stream going

      That’s a bit like the investigation into whether lethal bear attacks are because of their teeth or their claws - probably really interesting, but not critical to the question of avoiding the bear.

      I was led to believe it’s both. Global warming causes ice loss which contributes to global warming which causes more ice loss which contributes to global warming which causes more ice loss …

    Y’all ready to be gouged for survival items until money becomes irrelevant?

    P.S. ‘A Capitalist Apocalypse’ would be a fun title for a political comedy song.

    reference

    I was trying to look up why less polar ice causes shifts in the jet stream and this article cites an active debate around our understanding on this.

    The tweet does not really address that point, and makes the cause and effect sound definitive.

      What, are you saying a website called X where I can easily share both amateur porn, shitpost, and fight with other keyboard warriors isn’t a solid source for factual information? smh what are you talking about

      Next you’re going to tell me that drinking diesel fuel is bad for my longevity or something.

      The Xcretion says that less ice “is consistent with” a weaker jet stream, which does not imply a casual relationship. If A causes B and Y, then B is consistent with Y; or, more accurately, we can produce a useful model of the system that includes both less ice and a weaker jet stream, and have it be internally consistent.

    Even as the US hits record setting lows, the temperature of the planet as a whole remains above average. If it’s -20°F across the entire US, how hot must the rest of the planet be?

    I just hope we’re not seeing the start of a shutdown of the North Atlantic current, which is likely what led to the Younger Dryas ice age, which marked a dramatic climate shift and widespread extinction event over just a couple of decades:

    The change was relatively sudden, took place over decades, and resulted in a decline of temperatures in Greenland by 4–10 °C (7.2–18 °F), and advances of glaciers and drier conditions over much of the temperate Northern Hemisphere. A number of theories have been put forward about the cause, and the hypothesis historically most supported by scientists is that the Atlantic meridional overturning circulation, which transports warm water from the Equator towards the North Pole, was interrupted by an influx of fresh, cold water from North America into the Atlantic.

    Right now, it’s looking like that may have already started: Study: Warning of a forthcoming collapse of the Atlantic meridional overturning circulation. If that’s the case, things will become very hot and then abruptly freeze, not over the course of a century, but virtually overnight.

      When you stop and actually think about our situation you realise how thin our operating margins are, we are at the mercy of whatever the planet does and our safety is subject to immediate dismissal should the conditions change. Worse of course are the random cosmic whims which could wipe us out instantly at any time e.g. comets, the sun going weird, etc.

      Ice ages typically happen due to very low insolation or the ability of solar energy to reach the surface of our planet. Insolation is a term often used when describing how much energy a solar panel can create.

      Right now we have a big problem with too many greenhouse gases, which exacerbate the insolation we already have. It is heating our oceans rapidly, thus causing the break up of ice sheets in the Arctic and Antarctica. At some point the oceans won’t be able to absorb the heat we are receiving and air temperatures will begin to rise as well. Equilibrium. Hence Venus by Tuesday.

      So maybeish, so there is the possibility that warming of the oceans will cause the large ocean currents to slow/stop. This will reduce the amount of mixing of ocean water. Causing greater salinity and temperature gradients in the oceans relative to latitude. Making the Arctic ocean colder and the tropical ocean warmer. This colder Arctic ocean would lead to lower Arctic temperatures and an increase in ice, increasing the albedo of earth. The higher albedo would reflect more sunlight cooling the planet into an ice age.

      Having said all that it is important to note, first if this happens it will be on geologic time scales. So the planet will still get a lot hotter first. Second it is just a hypothesis, we don’t know what is going to happen on a longer scale because this period of warming is unprecedented in earth’s history. Yes it has been hotter and had higher CO2 levels, but not anywhere the speed of chance we have had in the last 100years. So using past trends to predict the current change will be vague at best.

      TLDR: it is still going to get a lot hotter before any chance of getting colder.

        Correct me if I’m wrong, but this warm ocean leading to cold poles is one of the suspected mechanisms that cause repeated glacial/interglacial periods in ice ages, right?
