what is the projected temperture increase by 2099 if carbon emissions are not reduced?What is the projection if carbon emissions are reduced?

There is unanimous agreement among the coupled climatecarbon cycle models driven by emission scenarios run so far

that future climate change would reduce the effi ciency of the

Earth system (land and ocean) to absorb anthropogenic CO2.

As a result, an increasingly large fraction of anthropogenic CO2

would stay airborne in the atmosphere under a warmer climate.
