ABSTRACT
Interactions between the carbon cycle, climate and human societies are subject to several major vulnerabilities, broadly defined as factors contributing to the risk of harm from human-induced climate change. We assess five vulnerabilities: (1) effects of increasing CO on the partition of anthropogenic carbon between atmospheric, land and ocean reservoirs; (2) effects of climate change (quantified by temperature) on CO fluxes; (3) uncertainty in climate sensitivity; (4) non-CO radiative forcing and (5) anthropogenic CO emissions. Our analysis uses a physically based expression for , the peak warming associated with a cumulative anthropogenic CO emission to the time of peak warming. The approximations in this expression are evaluated using a non-linear box model of the carbon-climate system, forced with capped emissions trajectories described by an analytic form satisfying integral and smoothness constraints. The first four vulnerabilities appear as parameters that influence , whereas the last appears through the independent variable. In terms of likely implications for , the decreasing order of the first four vulnerabilities is: uncertainties in climate sensitivity, effects of non-CO radiative forcing, effects of climate change on CO fluxes and effects of increasing CO on the partition of anthropogenic carbon.
