I think that you exaggerate the dangers of climate change. I have been studying anthropomorphic climate change for over 30 years now, and I first publicly warned about its dangers 29 years ago. I have dedicated years to fighting the climate change deniers with scientific information. So please don’t dismiss my criticisms as political in nature.
First, there’s no hard-and-fast deadline that we must meet. Climate change is a slow, creeping threat that grows a little worse every year. We needed to start making changes thirty years ago, and every year that we put off reducing carbon emissions makes matters worse. But there’s no absolute cut-off date.
Second, climate change does not by itself pose an existential threat to civilization. We won’t bake to death. We won’t drown in rising seas. In fact, most of the effects will be boring. I’ve already incurred about $5,000 in costs due to climate change, but most of those costs were preventative measures for the future. Climate change won’t burn us to death; it’ll nickel and dime us to death. It’ll be like being nibbled to death by ducks.
The real dangers of climate change are two-fold. First, the economic costs of climate change will continue rising until we reach the point where the damages due to climate change exceed the growth of our economy. At that point, we are doomed to ever-increasing poverty. That in turn will start the hunt for scapegoats and we’ll revert to totalitarianism.
The other danger is that in our desperation, we’ll resort to geo-engineering schemes. Those schemes will have different impacts on different countries. Country A might implement a scheme that helps it but hurts Country B. Everybody will be doing this kind of thing, and we’ll eventually resort to ‘other means’ in resolving our political differences: nuclear missiles.
So rest easy: climate change won’t kill us. We’ll do that job ourselves.
I have written a detailed critique of the costs of Mr. Sanders’ proposals for climate change; you might wish to review and comment on it. I’ll write up a critique of his technical proposals later.
