  • Soil respiration is the primary path by which CO2fixed by land plants returns to the atmosphere. Estimated at approximately 75 × 1015gC/yr, this large natural flux is likely to increase due changes in the Earth's condition. The objective of this paper is to provide a brief scientific review for policymakers who are concerned that changes in soil respiration may contribute to the rise in CO2in Earth's atmosphere. Rising concentrations of CO2in the atmosphere will increase the flux of CO2from… CONTINUE READING
