What’s wrong with 90% loss of glaciers in Switzerland? Exposure

According to foreign media reports, on November 25, the Swiss Academy of Sciences issued a statement saying that in the past year alone, the melting rate of glaciers in Switzerland has reached 2%, and in the past five years, the melting rate has reached 10%, the highest observed value in more than a century. According to the Swiss government, more than 500 glaciers have disappeared in Switzerland. If the global emission reduction target cannot be achieved, 90% of the existing glaciers will disappear by the end of this century. In fact, glaciers in many parts of the world are facing a similar situation. For example, the NOAA pointed out that the change of glaciers in Alaska in the 19th century and the early 21st century is worrying.

Built in 1882, the Belvedere Hotel is located at the folka pass, overlooking the Rhone glacier. Three years ago, however, the hotel was forced to close because the glacier retreated two kilometers.

In the middle of the 19th century, photos of the Rhone glacier, which went deep into the valley, showed that the front of the glacier was 100 meters thick, but now it has completely disappeared and become a river and lawn.

In another photo taken at the end of the 19th century, a man sits on a boulder in front of the largest Alec glacier in the Alps. But now it can be seen that the huge ice channel and the main body of the glacier are no longer integrated.

Mattias HUS of glamos, a Swiss glacier monitoring agency, says Switzerland has lost about 2% of its glaciers in the past year. Never since the beginning of the measurement has such a rapid rate of glacier decline been seen.

The severe heat wave in summer 2019 accelerated the melting of Swiss glaciers, and the melting rate broke the historical record. Even if the snowfall in winter increased, it was not enough to slow down the melting rate of glaciers.

In eastern Switzerland and Northern Alps, melting is particularly severe. The flow of pichor glacier in the northern Alps has decreased by 80% - 90% in three years. Researchers at the Federal University of technology in Zurich have removed it from the glacier monitoring network.  

On November 25, 2019, the World Meteorological Organization issued the No. 15 annual report on greenhouse gases. In this report, the World Meteorological Organization pointed out that the concentration of major greenhouse gases (carbon dioxide, methane, nitrous oxide) in the earth's atmosphere continued to increase, and the world average concentration in 2018 reached the highest level ever! The World Meteorological Organization also pointed out that at present, the The growth rate of carbon dioxide concentration is significantly faster than that in the past 10 years, which shows that the growth rate of carbon dioxide concentration is still significantly accelerated in the last 10 years.
