This lecture briefly focus on Global Warming Prediction. Calculate the carbon emitted due to burning fossil fuels and the CO2 concentration in the atmosphere, accounting for residence time. It is very important to account for fossil-fuels depletion when calculating Global Warming predictions. Otherwise, it might be assumed that more carbon can be put into the atmosphere from burning fossil fuels than physically possible. Calculating fossil-fuels depletion is not exact, but can be estimated reasonably well.
