The animation below shows the main components of the dry atmosphere, with the increasing fraction of CO2. Each pixel represents 1 part per million (ppm). Two 50 year projections for CO2 levels are also shown, one with the Kyoto Protocol and one without. Note that both of these projections ignore the likely increases due to industrialization of China and India. However, the difference between these two projections, shown in the final frame and labeled “This is the amount of CO2 that Kyoto would keep out of the atmosphere in the next 50 years” would be little changed, since both China and India are exempt from the limits imposed on the industrialized countries.

*The pre-industrial CO2 levels are typically given as 280 ppm. It is now about 380 ppm. I estimated the 50 year increase with the Kyoto Protocol by simply increasing the CO2 at a rate 5.2% less than the increase rate of 1990
for 50 years. This ignores increases by China and India. I estimated the 50 year increase without Kyoto by simply adding 2.25 ppm per year for 50 years. This also ignores increases by China and India. The difference between the two estimates is essentially independent of China and India.
