摘要：
Atmospheric CO2 concentrations can be reduced by storing carbon in vegetation. However, this lowers the concentration gradient between the atmosphere and other potential carbon reservoirs, such as the oceans, and thereby reduces the subsequent inherent rate of removal of CO2 from the atmosphere. Hence, storage of carbon in temporary reservoirs can reduce atmospheric CO2 concentrations in the short term, but if the carbon is released again, it will increase concentrations in the long term. It must, therefore, be considered when, or, indeed whether, to store carbon in vegetation sinks.To determine an optimal strategy, the exact nature of climate-change impacts needs to be considered first. Impacts can be mediated by:
