Increase in soil temperature will negatively impact SOC, but primarily in higher latitudes  . Experiments have shown that warming can accelerate litter mass loss and soil respiration  and reduces the soil recalcitrant C pool . SOC losses may speed up soil structural degradation, changes in soil stoichiometry and function , with downstream effects on aquatic ecosystems. The rate and extent of SOC losses vary greatly depending on the scale of measurement , soil properties, climate, land use and management practices .
