Find the main culprit causing the glaciers to melt

According to the first scientific study of the specific human impact on melting in glaciers, scientists found that humans are the main cause of this phenomenon.

>>>Antarctic glaciers are melting faster

More than 60% of the recent melting ice phenomenon in the world is a consequence of human activity .

According to a study published on August 14 in the American journal Science, since the first glacial melting event in 1851 to the mid-20th century, there is no evidence that humans is the cause of this phenomenon.

From the mid-20th century to the 1990s, people were responsible for 25% of the melting of glaciers in glaciers and this rate increased to 69% during the period from 1991 to the present, causing great concern in World studies of world climate.

According to Ben Marzeion, climate expert at the University of Innsbruck (Austria), the melting of glaciers is accelerating and it is possible to conclude that the cause is due to human activities . The most affected by human impact are the glaciers in Alaska and the Alps.

According to Marzeion experts, in the past two decades, an average of 295 billion tons of ice melted each year due to human impact and about 130 billion tons of melting due to natural causes.

Geophysicist Regine Hock of Alaska Fairbanks University, a member of the research team, said the jump from 25% to nearly 70% is a significant increase that experts worry.

The amount of melting water from glaciers contributes 40% in every inch (2.54cm) of sea level rise in every decade. This number will increase if we include melting of the ice sheets and seawater expansion due to global warming.

The study was conducted with a high margin of error. Specifically, the minimum level of human impact can be only 45%, or up to 93%. However, in research, scientists often take the average.

Science proves that there are many causes of melting, such as an increase in the Earth's temperature, excessive emissions of greenhouse gases and changes in farming and land use. This is a long process of change and is difficult to identify immediately. Therefore, if not researched and prevented in time, the Earth will most likely enter the first phase of the intense melting process, causing immeasurable impacts on people's lives and destruction. the development achievements that the world has had to work hard to achieve.
