Temperature effect on erosion-induced disturbances to soil organic carbon cycling

Erosion exerts control on soil organic carbon (SOC) and both erosion SOC are affected by climate. To what extent temperature controls the coupling between these erosion–C interactions remains unclear. Using 137Cs inventories from catchments spanning different climates, we find that increasing decomposition rates with result in efficient replacement of laterally lost eroding areas but lower preservation deposited depositional areas. When combined at landscape level, erosion-induced C sink strength per unit lateral flux increases 0.19 g (g C)−1 0 °C to 0.24 25 °C. We estimated global 0.050 Pg yr−1 induced water croplands 7% because climate change. Our results reveal a negative feedback loop change disturbance cycling. The authors demonstrate interacting impacts warming Under warming, they project increased SOC, an overall increase erosion.
