>But our local "system" has a gigantic miasma of incandescent plasma on our doorstep. The Earth itself should not need to worry about entropy for a long while yet...

I interpret GP's reference to thermodynamics/entropy as generating the "arrow (asymmetry) of time,"[0]

Which exists (at least for us matter-based beings) as remembering the "past," but not the "future," and local fluctuations in entropy don't affect that at all.
