Geophysical Research Letters" recently published a report entitled "carbon sequestration" desert hidden under the article pointed out that the earth may have a huge desert containing carbon sequestration potential in the aquifer, equivalent to about 1.25 times the carbon content of all plants on land.

Researchers at the Chinese Academy of Sciences Xinjiang Institute of ecology and geography researchers and the Woods Hole Research Center were collected in the Tarim basin water samples, including upstream glaciers melt water, desert below the water samples and agricultural irrigation water, carbon and carbon were measured for each inference in water samples.

Desert crops absorb carbon dioxide from the atmosphere, some of which are released into the soil and into the roots of plants, researchers believe. At the same time, microbes can increase carbon dioxide levels in the soil by breaking down sugars in the soil. Farmers over irrigated land also cause salt to dissolve into the ground with water dissolved carbon dioxide, creating huge carbon sinks. It is estimated that the annual loss of carbon in the Tarim desert is almost 12 times the amount of carbon stored in agriculture.

The researchers pointed out that the understanding of carbon position, can improve the prediction model of future climate change, improve the calculation accuracy of the carbon budget, not clear in the total temperature of the earth caused by fossil fuels under the condition of major changes in human combustion.
