Tying future human CO2 growth projections to human population growth projections and adding in a 30 % estimated increase in per capita CO2 emissions by 2100, gives you a CO2 level of 640 ppmv (or a bit higher than IPCC case B2).

While the above analysis yields good results for by tying past climate change to increases in human CO2 emissions, it should be cautioned that the suggested exponential time relation is not suitable for projecting the future over longer time periods, because of possible changes in human population growth rates and absolute limitations on carbon available in remaining fossil fuels.
