Frozen Soil is getting lesser and lesser on Qinghai-Tibetan Plateau due to global warming

It is reported that the frozen soil which is also called tundra on Qinghai-Tibetan Plateau are disappearing. Frozen soil less than 10 meters will disappear in 7 years.

Frozen soil is good for plants to grow and good for keeping the land wet by providing humidity to the surface on earth, which is the best thing to prevent desertification. The report says that seasonal frozen soil has reduced to 2.8 meters from 3.2 meters in the last 30 years.

Many short root plants will die as a direct result of the reduction of the frozen soil. This will cause desertification, solifluction which will endanger the Qinghai-Tibet Railway, road and people's life on the plateau.

30% of land in China is desert and 37% of the land had problems of water and soil erosion, plus 0.1% of the rest of the "good land" is "desertized" every year. (the circle on the picture are the region of Qinghai-Tibetan Plateau)

The two major rivers, the Yangtze River and Yellow River are originated from Qinghai-Tibetan Plateau, with the desertification of origin of these two rivers, what do you think will happen to China? The flood, the drought, the three gorges dam, the life….. I can't imagine.

We are endangered by global warming. What can we do as a tiny human being? Maybe it is time for us to consume lesser one-off wooden chopsticks and to visit Tibet before the desert does.

  2. As an American, I apologize for the above comment. Despite our democratic government, we terribly mismanage our water resources. Over government is dominated by commercial interests - noncommercial properties and resources get short shift. As a consequence, Lake Mead, a water resource for large populations in the Southwest, is drying up. As re: the thing about God - I believe in God as a transcendent force that is dispassionate; God is the source of all life on this earth; I don't believe God favors those who speak English and I don't believe that humans can really fathom God. In my view, one can know more about God from looking at the creation and understanding how it is, not from translated copies of religious text from misunderstood cultures.
