Explain what about thermodynamics allows for a closed system to progress forward in time without increasing disorder please. Or are you proposing we export the

  There's a very large difference and lots of possible expressible dynamics between "no entropy increase" and "lots of entropy increase". Keep showing us how little you know about the topics on which you comment. PS the Earth is not a closed system either. The incident sunlight is the only thing that keeps the Earth warm at the macro scale, and energy radiates back out mostly in the infrared range. The amount of greenhouse gases can differ and the global temperature will differ as a result.

    And does our specific position on that gradient matter, at all? Again, I’d love to hear your explanation of how we’re exporting this entropy. Black body radiation? I don’t think that’ll be enough.

        The earth has a certain amount of energy sequestered. The sun provides a certain (constant) amount additional per year. Black body radiation emits a certain (variable, proportionate to temperature, perhaps) amount per year. Everything else is just meaningless argument about constant factors.

          > Everything else is just meaningless argument about constant factors. For the inhabitants of Earth, it most certainly is not meaningless, and the whole point is that they're not constant factors. For one, the composition of the atmosphere plays a huge role, and it is not constant thanks to both natural and human-driven processes.

            I’m an inhabitant and it’s meaningless to me. What about it holds meaning to you?

  It's not a closed system, we import massive amounts of energy from the sun every day. Some of it escapes back into space, depending on the atmosphere/albedo/etc. Anyways, how do you think radiators work on space stations?
  • jakear 3y ago
    So you’re saying we’re doomed to an increasingly unpredictable and disorderly existence, regardless of our actions? I agree.
    • tiedieconderoga 3y ago
      No, I explained how your earlier comment was facile to the point of being incorrect, like you asked. How you interpret that is up to you.
      • jakear 3y ago
        I may have missed your point, was it praying to the almighty god “black body radiation”?
        • stouset 3y ago
          Sarcasm layered on top of staggeringly proud willful ignorance just isn’t the winning combination you seem to think it is.
          • jakear 3y ago
            “I know the answer but I’m so smart that I won’t explain it” is equally useless.
            • stouset 3y ago
              You might wish to reread the comments in reply to you—in good faith this time—and realize that people have in fact tried to explain it to you. Perhaps you were too busy knocking over chess pieces and strutting around on the board victoriously to notice?

  The earth isn't a closed system. It receives energy from the sun which can be used to decrease entropy here on earth. Like an organism receiving energy from eating other organisms can regulate its own entropy. Sure you can't escape entropy because the sun will eventually die too, but that's a while away.
  • jakear 3y ago
    What is the mechanism by which excess energy is used to permanently sequester/export entropy?
