The study looked at how carbon burial in Bosten Lake has changed since 1950 due to climate and human activities. They found that the amount of carbon being buried has been increasing over time, with more inorganic carbon being buried compared to organic carbon. The increase in organic carbon burial was likely due to warmer temperatures and increased human activities. However, in recent years, there has been a decrease in inorganic carbon burial due to lower biological activity and a drop in the lake level. This shows that the storage of carbon in lake sediments is important for the carbon cycle, especially in arid regions like northwest China.
