So, step by step, I went full circle. If, at the beginning, I was more worried about depletion than about climate, now it is the reverse. Not that I stopped worrying about peak oil, I know very well that we are in deep trouble with the availability not just of oil, but of all mineral resources. But the recent events; the melting of the polar ice cap, hurricanes, droughts, wildfires and all the rest clearly show that the climate problem is taking a speed and a size that was totally unexpected just a few years ago. Climate change is a gigantic problem: it dwarfs peak oil in all respects. We know that humans have lived for thousands of years without using fossil fuels, but they never lived in a world where the atmosphere contained more than 400 parts per million of CO2 - as we are going to have to. We don't even know if it will be possible for humans to survive in such a world.
