If the small amount of warming we have experienced were such a catastrophe, why has everything gotten so much better? Fossil fuel-driven prosperity has cut extreme poverty around the world by nearly two-thirds, allowed us to dramatically increase food production and cut hunger and malnutrition around the world, spread access to electricity to billions of people on every continent, cut child mortality in half, and added 7 years to average life expectancy. If you could have prevented the fossil fuel use at the cost of never having experienced all this progress, would you have done so?
