Experts talk about glaciers in various places: the last line of defense to protect climate change requires the world's efforts

At 18:00 on August 12, 2022, the Central Meteorological Observatory issued the first highest -level high -temperature red warning, and high -temperature warning continued. As a "window" for climate change, glacier melt in various places has continued to pay attention. Shen Yongping, a researcher at the Northwest Ecological Environment Resources Research Institute of the Chinese Academy of Sciences, believes that climate change is not a matter. surroundings.

Global heating waves are coming

Since the summer of 2022, the rare extreme heat waves have occurred in China, the United States and Europe, which has caused disaster effects on the human socio -economic and natural ecosystems. Continuous high temperatures have caused problems such as shortage of electricity, crop production, and thermal radiation disease in many places.

One consequence of global warming is the increase in extreme weather events, such as heat waves, droughts, floods, cyclones and wildfires. Some of the severe heat waves that have occurred in the past few decades have made heat waves a hot topic of climate change research. "Heat" has a dual meaning: high temperature and high scientific activities. In Germany, some glacists said that 2022 will be a record of melting of glaciers. It is speculated that due to factors such as rainfall, decreased snowfall and drought, and hot weather, the melting volume of glaciers in the Alps this year may increase by about 50%compared with previous years.

Shen Yongping noticed that under normal circumstances, Iran and Qinghai -Tibet Plateau blocked the high -pressure heat waves in the west, and the western region of my country would not suffer too much high temperature weather. In June this year, after the heat wave came from the Iranian plateau, the Qinghai -Tibet Plateau approached the Qinghai -Tibet Plateau, which was affected by high pressure and high temperature and circulation abnormalities. High temperatures were concentrated in northwest, North China and the Yangtze River Basin in my country. Sichuan and Chongqing, located in the Yangtze River Basin, are affected by El Nino's phenomena that are relatively small. Extreme weather incidents are frequent. Drought, rainstorms, floods, and forest fires are frequent.

From last winter to this spring, the entire Qinghai -Tibet Plateau rainfall was relatively small, and there were fewer snow on the mountains, and those who encountered strong glaciers were not just the western region.

China Glacier resources are distributed in Xinjiang, Tibet, Qinghai, Gansu, Sichuan and Yunnan in western China. There are not many glaciers in Sichuan. The glaciers in Sichuan Province are distributed in Laoshan, Daxue Mountain, Salu Mountains, and Mountains in Hengduan Mountains. Less than the above four provinces. The glaciers in the province are distributed in the four cities (autonomous prefectures) of Ganzi, Aba, Mianyang and Ya'an. Among them, the number of Ganzi Tibetans has the largest number of glaciers (482) and the largest area (515.49 km2).

Recent Monitoring, the results show that the six glaciers have gone through a fierce melting and contraction process. The area is declining, a decrease of 5.1 square kilometers, an average of 0.12 square kilometers per year. At present, the remaining area of ​​glaciers is only 1.75 square kilometers. The end of the glacier also increased from 4587 meters above sea level to 4900 meters. With the changes in the climate, strong glacier retreat will pose a great threat to the development of the district.

Shen Yongping also noticed that netizens recently photographed the "Four Girls Mountain Glacier Impliers" incident. The marine temperature glacier of Simuashan itself is more sensitive to the climate, and the high temperature has a great impact on glaciers. "It can be said that the glacier melted this year, and the glacier was formed for thousands of years. Essence

He believes that glacier ablation has a greater impact on Sichuan's tourism and ecology. In the high altitude places where other glaciers are concentrated in my country, there is a small population, but the glaciers in Sichuan are not high. The beauty of landforms and landscapes is a popular attraction. The value of tourism brings is very high. Ecological benefits are obvious. "

Initiative: Protect the reasonable adjustment of glaciers

With the warming of global climate, glaciers melted phenomena, which brings us far more than tourism. "Climate change is not to play, it is a real environment that can be felt. The main reason is that it has a lot to do with human carbon dioxide emissions and ecological destruction."

There are more and more extreme events brought by climate warming. For example, the impact of high temperature on high mountains and frozen soil, which leads to the melting of frozen soil and loose mountains. As soon as it encounters heavy rain, natural disasters such as mudslides and landslides are prone to occur.

Shen Yongping believes that climate change is not a country, and it needs to work together in the world. If the temperature of the earth rises too fast, the animals and plants cannot keep up with the changes in the environment, and catastrophic extinction will occur. As the scope of human activity is larger, the space for human activity has compressed the space of natural changes, which will inevitably affect the safety of human society. "Humans still have to leave something for their children and grandchildren."

Shen Yongping suggested that "accelerate the ablation of glaciers in the western region, it is proposed to take measures to make measures reasonably, and the local area should reasonably adjust the production method according to the climate conditions and water resources. Due to the increased risk of glacier disaster due to glaciers, the local area needs to strengthen the disaster. Management to improve the adaptability of the local community. "
