I'm skeptical of any claim so big and contrarian, but it does fit with The Adams Law of Slow-Moving Disasters. Simply stated, my observation is that whenever humanity can see a slow-moving disaster coming, we find a way to avoid it. Let's run through some examples:
Thomas Malthus famously predicted that the world would run out of food as the population grew. Instead, humans improved their farming technology.
When I was a kid, it was generally assumed that the world would be destroyed by a global nuclear war. The world has been close to nuclear disaster a few times, but so far we've avoided all-out nuclear war.
The world was supposed to run out of oil by now, but instead we keep finding new ways to extract it from the ground. The United States has unexpectedly become a net provider of energy.
Can anyone give me an example of a potential global disaster that the general public saw coming, with at least a ten year warning, and it actually happened as predicted?
