Slide Words: Net Carbon Accumulation by the Ecosystem Over Time

Slide Image: On the left side of the slide is a flow chart showing the Carbon Cycle. Arrows go from boxes labeled “Atmospheric CO2” to “Vegetation Biomass” to “Soil Organic Matter” and back to “Atmospheric CO2.”

On the right is a graph representing a time of 100 years, which shows an example of cumulative effects of warming on carbon stocks. A positively sloped line labeled “Coupled Carbon-Nitrogen dynamics” shows how there will be net sink of carbon to the land under warming; a negatively sloped line labeled “Carbon-only dynamics” indicates a net source of carbon to the atmosphere under warming. This is a single-point example for temperate deciduous forest.
