Reply to reviewer ESDD-1-C135-2010 comments on “Assessing lifeʼs effects on the interior dynamics of planet Earth using non-equilibrium thermodynamics” by J. G. Dyke, F. Gans and A. Kleidon

This manuscript provides some very interesting and thought provoking models of the interaction between Earthʼs interior and surface, between biotic and geologic activities. The simple models are very interesting and I believe the work presented in this manuscript deserves being published. Still I have so major comments concerning the presentation. Indeed, the equations are simple but the assumptions used and the notations are very often simply not explained. It is very cumbersome to try to guess what the authors have assumed, what is the meaning of the symbols and then try to get the same equation. Quite often, some assumptions are given at the end of the problem (example line 4 page 213) not at the beginning.
