Papers like 1, 2, etc. and the work of Axel Kleidon (e.g. 3) suggest that the the biosphere increases the production of entropy of Earth but I'd like to know if we could quantify this in a simple way. What would the entropy production be without life? If we knew that then the difference between what it is estimated to be would be easy to calculate.

  • $\begingroup$ This sounds like a better fit to the biology stack. $\endgroup$ – John Apr 29 at 20:28
  • $\begingroup$ I suggest going to the biology stack and asking a much simpler question that will give you the same answer. "how much energy is consumed by all life on earth combined" $\endgroup$ – John Apr 30 at 1:31

    $\begingroup$ I think that the thermodynamics and entropy of Earth's entire biosphere is of more interest to today's Earth Scientists than today's Biologists. $\endgroup$ – uhoh Apr 30 at 7:01

    $\begingroup$ @MooseSmart can you link to something in the help center or meta that says that Earth Science SE questions must "mention something geographical (Like Volcanism, etc)"? Thanks! $\endgroup$ – uhoh May 6 at 2:08

    $\begingroup$ Imo this a good question, a very complex one. Maybe one day someone comes along who has a better understanding and gives an answer, if that exists. $\endgroup$ – Earthworm May 6 at 14:50
