Before 2000, the largest lake in Tibet had always been Nam Co with beautiful scenery and an area of 1961 square kilometers, but its status has been in jeopardy, because since the 1980s and 1990s, Serin Co has undergone a rapid expansion. From 1,666 square kilometers in 1976 to 2,323 square kilometers in 2010, the area increased by 39.5%, making it the largest lake in Tibet.
Behind the expansion of the area is the increase in glacial melt water, which will reveal a cruel fact
There are more than 1,500 lakes, large and small, on the Qinghai-Tibet Plateau, most of which are increasing in area. According to the preliminary research results of the Institute of Tibetan Plateau Research of the Chinese Academy of Sciences, the decrease in precipitation, glacial melt water and evaporation is due to the expansion of the area of Selin Co. main reason:
Glacier melt water: 9.5%
Evaporation reduction: 14%
It seems a bit contrary to common sense that the glacier meltwater only increased by 9.5%, but in the Selin Lake area in the hinterland of the Qinghai-Tibet Plateau, the water vapor in the Indian Ocean is difficult to reach, and most of the water vapor in precipitation also comes from the glacial meltwater. Therefore, the glaciers on the Qinghai-Tibet Plateau are increasing. The reduction in area is an indisputable fact.
According to the glacier data of the second Qinghai-Tibet Plateau scientific expedition, from 1984 to 2016, the area of glaciers on the Qinghai-Tibet Plateau has been reduced by 31.93%, and the snow-covered area on the edge of the glacier has been reduced by 73.64%. The most shocking news is 2020. Vegetation appeared on Mount Everest at a height of 6,159 meters in February of the year. Originally, it was covered with ice or snow, but now it has grown green grass.
The snow and ice of Mount Everest melted, and the cruel truth will be revealed
According to a research team from the University of Milan, Italy, Mount Everest has decreased by 43% in the past 50 years, and the rate has increased from 0.12% per year in the 1950s to 0.7% now, which is close to 6 times. The Everest glacier has greatly melted. It will bring an excellent good news and extremely cruel facts!
What’s the great good news?
Mount Everest is a popular destination for climbers all over the world. From the time when the British Edmund Hillary climbed Mount Everest for the first time, more than 5,000 people have successfully climbed to the summit, 295 of them were killed, and hundreds of others were missing. Some were found after the snow melted. For example, the famous green boots were confirmed to be the 28-year-old Tsewang Paljor who disappeared after the Indian border police expedition climbed to the top.
Therefore, after the ice and snow melt, the bodies of missing persons will be exposed every year and be found. So for the victims and their families, it is undoubtedly good news. After all, you have to see people when you die, and even if you die, Then finding the corpse is also great.
What is the cruel news?
Although the remains of the climber were found, they could not be brought back. Perhaps this is the most painful thing for relatives! Up to now, there are about hundreds of dead bodies on Mount Everest. Except for a few, they still remain as they were when they were discovered. At most, the bodies are on the only way for climbers, and they can be seen every time. By the time, I was really disrespectful to the deceased, so it was humanitarian. Some climbers moved the dead bodies of the victims to places where they could not be seen, and they also built up stones to cover them a little.
There are so many dead bodies on Mount Everest, why not transport them down?
Some people may ask, why don’t you bring so many dead bodies on Mount Everest? In fact, it is extremely difficult to bring back a corpse from Mount Everest!
From the perspective of the distribution of Everest corpses, there were some victims from 5000 meters to 8000 meters, but most of the victims were killed during the summit or retreat. The density of corpses above 8000 meters is the highest. Since the opening of Pearl in 1924 Since the summit climbed, more than 200 climbers have been killed near this height.
The total amount of oxygen here is only about 1/3 of the plain area. Oxygen is thin. Once a cold will cause pulmonary edema, or altitude sickness, or oxygen depletion, the only thing waiting for the climber is death, and the climber’s physical strength is already at this height. Almost exhausted, it is impossible to even bring a few more oxygen cylinders, so at this height, everyone can only protect themselves.
Oxygen cylinders discarded after exhaustion on Mount Everest
Once a climber is in danger, no matter how good his companion is, he can only watch him die, because the help that can be provided is extremely limited! On May 22, 1998, Francys Arsentiev and her husband Sergei Arsentiev reached the summit of Mount Everest together. During the descent, the two couples separated. The husband returned to the base camp and found that his wife did not arrive as scheduled. He realized that his wife might be in danger. Regardless of fatigue, bring an oxygen cylinder and set out to find a wife!
But unfortunately no one has seen Sergei Arsentiev again, and his wife Francys Arsentiev is already in a semi-comatose state at this time. Uzbekistan climbers met her on the way down, but at this time they could not move on their own. The team leader left part of the oxygen cylinders and supplies to her!
This is already the greatest help for a climber. After that, British Ian Woodall and South African famous climber Cathy O’Dowd met Francys Arsentiev again. At that time, they tried to help her, but at the time they were dying. The weather and the dangerous situation could only watch her die.
Her husband, Sergei Arsentiev, was not discovered by members of the Jake Norton expedition until 1999. Judging from the condition of the body, it should have been lost due to bad weather or slipped off the ice sheet and fell to death. Until now, the bodies of the two couples are still on Mount Everest, and they are far apart, which is really embarrassing!
US$70,000: You can bring a dead body
The Nepalese Sherpa guide has a special offer to bring the body, about 70,000 US dollars, some locations may be more expensive, of course, some companies responsible for mountaineering assistance will also offer prices, the price is similar, of course, this is not making money. , But it is too difficult to bring a corpse, and the climbers who are responsible for the transportation also risk their lives.
The airflow on Mount Everest is very complicated. Except for the base camp, most of the camps are not suitable for helicopters to take off and land, and even the conditions for hovering are not available, so they can only be brought down from the summit by manpower.
Further reading: Rainbow Valley
Just below the top of Mount Everest, about 8,500 meters on the north side, there is a famous Rainbow Valley. The team members who died during the summit of Mount Everest will basically roll down to this position. The colorful clothes are named Rainbow. Valley.
However, it is believed that the victims have been prepared to sleep on their favorite hiking trails since they chose to climb the mountain. The famous mountaineer Alan Arnette once said: “Climbers like always Stay in the mountains of eternal sleep”!
