Abstract

Stimulation of terrestrial plant production by rising CO 2 concentration is projected to reduce the airborne fraction of anthropogenic CO 2 emissions. Coupled climate–carbon cycle models are sensitive to this negative feedback on atmospheric CO 2 , but model projections are uncertain because of the ...
