Congratulations Umair, great minds thinking alike. You almost see the whole picture now. The true hideousness of our stupidity. You are about 85% of the way there.

You are still missing one key point. Here's the most important question we should have asked in 1976. When we still had a chance to stop this.

"How much CO2 will it take too raise the GMT 1.0C?" What is the safe amount of CO2 we can have in the atmosphere?

When you understand the answers to those questions, and why. Then you will understand the "whole" problem. Then you will understand just how bad it really is.

We need to act as if the Earth is about to be invaded by aliens and we get one chance to save ourselves. Because in the next 20 years, we do that or watch our civilization burn.
