Population and global warming with and without CO2 targets

The sensitivity of future global warming to variable population growth rates is reexamined as part of an ongoing debate over the extent to which climate change should be added to the list of concerns surrounding population growth. The UN 1992 low, medium and high population projections out to the year 2150 are run through an integrated climate-economics model which allows the effect of population variability to be traced through to CO2 emissions, concentrations, warming and economic growth.
