WOW! Great minds (?) do think alike. I just posted a parallel piece in reply to a critique of a comment I made on collapse2050.com, which you may wish to review. It was regarding a James Hansen piece reviewed by Sarah Connor and went into some detail regarding the thermodynamic issues of global heating and the human contribution, which I estimate at 11,000 BTUs at near rest daily, so 11 X 10e3 times 8.1 X 10e9 or 89 X 10e12 BTUs, and about double this for our domestic animals, so 1.88 X 10e14. Thanks for your interest in this all important subject and good to know you! Have a blessed day! Gregg
Interesting take on the second law of thermodynamics and entropy. You could also look at Lord Kelvin's dynamical theory of heat: "heat is not a substance, but a dynamical form of mechanical effect, we perceive that there must be an equivalence between mechanical work and heat, as between cause and effect." https://zapatopi.net/kelvin/papers/on_a_universal_tendency.html
You are familiar with the heat death of the universe (also known as the Big Chill or Big Freeze)?
Hi KB. Excellent comments! When I think of heat, I always see in my mind's eye the infrared photographs of the earth from space, unfamiliar views to those of us reared on the "blue marble" depictions of the early space age. A different planet is revealed- swirling bands, almost Jupiterian, of heat. Nothing to do with GHGs except as derivatives. I also think of the ISS photos on clear nights of our cities glowing with their lights in vast webs, all of them heat islands.
