Good try but no cigar. I'll save you the calculation. Developed countries produce 70% of the total global anthropogenic carbon dioxide emissions but have less than 25% of the world's population.
Let's redo that calculation. Current World population: 6.8 Billion. By 2050, we'll say 9.1 billion with roughly 80% of that growth in developing countries. Caution - Approximation only, but not as approximate as yours
Current Situation: Developed World 1.7 billion produce 4.97 Gigatonnes of Carbon annually
Third World (5.1 billion produce 2.13 Gigatonnes of Carbon.
Using current emission rates:
2050:Developed World: (2.1 billion people) produce 6.43 Gigatonnes of Carbon
Third World (7 Billion) produce 2.93 Gigatonnes of Carbon.
So you can see that it's nothing like a magnitude of 10 as you suggest.
Even factoring in China and India doesn't appreciably change the picture.
If we have a major world famine, do you think that will affect the developed countries' population or the third world countries most, and what effect will that have on the emissions scenario?
