对西伯利亚东北部70°N附近纬度的土壤CO2排放量进行了测量，其水平足以解释该纬度冬季大气CO2浓度的最大值。这种二氧化碳是由永久冻土层上方活动层底部的生物活动产生的。生态和人类学因素可能在刺激这种二氧化碳排放方面发挥作用。
Soil CO2 emissions at latitudes near 70°N in northeastern Siberia have been measured and occur at levels high enough to account for the observed winter maximum in atmospheric CO2 concentrations in this latitude. This CO2 is produced by biological activity at the bottom of the active layer above the permafrost. Ecological and anthropological factors may play a role in stimulating this CO2 emission.
