I don't know if the Earth's climate is as delicate as we fear. Our infrastructure is far more delicate when it comes to the Earth climate. The Earth is able to function within a homeostatic range (say, established over the past billion years) far more effectively than our infrastructure (established over the past few hundred years). The biosphere may also be involved with this, which has been raised in the Gaia theory line of argumentation.
