Tourists who were there to see the incident recorded it on camera when part of a hanging glacier broke off at a national park in Chile’s Patagonia due to increased temperatures and rainfall that weakens ice walls.

More than 1,200 kilometers (746 miles) south of Chile’s capital, in Queulat National Park, a glacier that is atop a mountain about 200 meters (656 feet) high shook and fell off in a video that went viral on Monday.

Raul Cordero, a climate scientist at the University of Santiago, said that while separations between ice masses occur frequently, this is concerning.

Because strong liquid precipitation or heat waves, both of which are occurring more frequently globally than only in Chile, might induce this sort of catastrophe, Cordero explained.

Before the collapse, Cordero claims that that region of Patagonia saw a heat wave with “very abnormal” temperatures.

An “atmospheric river” made up of rather warm air that was wet was also seen, according to Cordero. after this “river meets with Andean and Patagonian topography, it forms large clouds and discharges precipitation.

One effect of global warming, according to Cordero, is the destabilization of many glaciers, particularly those fragile glacier walls. In the same manner that the Himalayas and the Alps experienced comparable events a few months ago, that is the situation with what just occurred in Patagonia.

Scientists claim that abrupt increases in heat are related to greenhouse gas emissions and climate change brought on by humans. The U.N. A climate science council recommended earlier this year that governments and businesses severely reduce their use of fossil fuels in order to slow global warming and mitigate its effects.
