Satellite measurements showed that the melting of the glaciers it is happening much faster than in previous periods. According to estimates, the loss of ice and snow is already about 31% greater than it was 15 years ago on all mountain glaciers in the world. According to scientists, this acceleration is caused by human action.

The researchers used 20 years of data to calculate that around 220 mountain glaciers in the world have lost around 328 billion tons of ice and snow per year since 2015. That is enough to put a country like Switzerland under more 7 meters of water each year.

Global glacier thinning rates have doubled in the past 20 years, with half of that being in the United States and Canada.

This scenario shows the effects of the increase in global temperature, caused mostly by the burning of coal, oil and gas. Some smaller glaciers are disappearing completely.

Reducing the size of glaciers is a serious problem for millions of people who depend on seasonal melting of ice to have water available. In addition, rapid melting can cause deadly explosions in glacial lakes, such as those found in India.

Another problem is related to the increase in sea level, a process that is already happening and affecting the marine biodiversity. However, the melting of glaciers is a more long-term problem, since the main responsible for rising sea levels is the melting of the Greenland and Antarctic ice sheets.
