The Wikipedia article “Human” says that it’s been 200,000 years since anatomically modern humans developed in Africa.
Taking an average of 20 years for one generation, that leaves us with about 10,000 human generations in our history until now. The last 200 years in which most of the fossil fuel burned until now has been used account for only 10 of those, or only about 0.1 percent.
It is quite obvious that if humans want to survive another 10,000 generations, we need to phase out fossil fuels sooner or later. There is not enough left for even another 10 generations at present consumption rates.
It is an interesting question what percentage of the fossil fuel treasure these 10 generations already burned through. I am quite sure that is is substantially more than 0.1 percent, but I am not able to give an exact figure right now. I may want to come back to that question in a later post.
Anyway, once you look at the big picture (10,000 generations), it becomes super evident that humanity needs to phaseout fossil fuel anyway, even without our little global warming problem.
The only question is how fast that will happen. And, from my point of view (phaseout profit theory), if the fossil fuel companies will deal with the phaseout in a way that makes them money.
Which is to reduce production faster than necessary anyway, so as to increase prices early on in the transition.
