The world is facing a huge crisis, scientists: the Qinghai Tibet Plateau Lake is about to fade!

The Qinghai Tibet Plateau is the largest plateau in China and the highest in the world, known as the “roof of the world”. Its total area is about 2.5 million square kilometers, generally between 3000-5000 meters above sea level, with an average altitude of more than 4000 meters; the lake area of the Qinghai Tibet Plateau is 36899 kilometers, accounting for 45.2% of the national Lake area. It is the inland lake with the highest altitude, the largest number and the largest area in the world. The water resources of the lake account for 70% of the whole country. It is also one of the two most densely distributed lakes in China, known as the “Asian water tower”.

Most of the water in the Qinghai Tibet Plateau comes from melting glaciers, as well as atmospheric precipitation, surface and underground runoff. The Qinghai Tibet Plateau lives in the inland, and most of them are inland lakes. Because the running water carries a large amount of salt into the lake, it can only be discharged by evaporation. After a long time, it will become a salt lake. The lake water in the Qinghai Tibet Plateau is the birthplace of many rivers in China, and the Qinghai Tibet Plateau also makes use of its rich water resources Yuanyuan has helped us in many arid areas. It can be said that it has raised thousands of Chinese people.

Now, news is constantly coming out that the color of the lake on the Qinghai Tibet Plateau is slowly fading, and the lake is about to fade. What is the reason for this? According to the data in 2014, in the past 20 years, the area of inland closed lakes on the Qinghai Tibet Plateau was 25600 square kilometers, and now it has increased to 32300 square kilometers. In the 1980s and 1990s, the lake water on the Qinghai Tibet Plateau has been shrinking, but in 1976, it gradually changed from less than 1667 square kilometers to 2319 square kilometers. In the past decade, the water level has been rising every year However, all these are caused by global warming, accelerated melting of glaciers, increased precipitation, less evaporation, and significant increase in the area of most lakes. All these are important reasons for the desalination of lakes on the Qinghai Tibet Plateau. The Qinghai Tibet Plateau, which used to be “too high to be cold”, has become one of the most typical regions of global warming.

Many natural disasters are also coming. If the expansion is rapid, it will cause floods, debris flows and other natural disasters. In 2016, an ice avalanche occurred in Aru glacier in Ali Region, Tibet, causing serious casualties and threatening the fate of the Asian water tower. Many residents in the lower areas need to move, because the lake water is likely to submerge their villages. Many plants in the Tibetan Plateau also need to move Climate warming will lead to the thawing of frozen soil, which may also reduce the function of carbon sequestration. Climate warming has also caused potential risks to the agricultural ecosystem. If people do not take measures in time, the consequences are really unpredictable.
