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?
