Just taking since life developed, our planet has been being hit by sun for 4.2bn years. If Earth had no way of dissipating heat, we’d have burned to a crisp by now. No?
Digging that oil up from the ground and the burning it does a tremendous amount to free up all that energy stored in a low-entropy system.
The book Into the Cool makes an interesting case regarding this overall concept.
> Of particular importance, although planets and stars (including the Earth and Sun) are neither in thermal equilibrium with their surroundings nor perfect black bodies, black-body radiation is still a good first approximation for the energy they emit.
Fine, you win Timon3, earth is not a blackbody because blackbodies don't actually exist.
It's fine to say "the earth behaves similarly to a black-body" or "a black-body is a good approximation for the earth". But that's different from "the earth is a black-body".
