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

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.
