The fact is that the planet is already massively geo-engineered. There is no cyclical ecology from which we could withdraw in order to allow it to go back to its homeostatic balance and order. The problem is thus not whether to refuse to geo-engineer. It is rather to choose how to geo-engineer. Are there ways in which the vast global infrastructure already in place can be qualitatively transformed in order to make something else? Could there be a geophysics rather than a geopolitics of hibernation?
