Thanks for the link. People are starting to realize that the ice age was the result of the carbon being stripped out of the biosphere and buried forever, leaving Earth a cooler and cooler place, with a greatly reduced tonnage of living things.
I don't think we have even a very remote chance of overshooting and creating runaway cooking into a Venus-style oven.
Any fossil hydrocarbons we extract were alive once upon a time. CO2 levels were much higher millions and a billion years ago, not to mention heaps of methane in the primordial world. The planet never cooked. It has cooled. When it cooled enough and life got going, there was a halcyon era of intense life.
But gradually, limestone deposits built up, coal deposits, shale, heavy oils, gas and lighter oils were all stripped and stored, much of it forever, reducing the carbon available to keep the place livably warm. Life was being reduced to an narrow equatorial belt during increasing glaciations.
We don't have a hope in hell of getting out more than a small fraction of the fossil carbon. We are fighting a rearguard action and can't succeed other than for a thousand years or two, which is long enough for the next stage of evolution, which is under construction now. Cyberspacoids and It! CDMA and CDNA, together to the end. CDNA = cyber deoxyribonucleic acid aka genetic engineering. No more natural variation and guesswork of human mating. We take over now.
