Quirat National Park, located in the Eisen region of southern Chile, contains part of the South Patagonian Ice Sheet, and now some of the glaciers have suddenly collapsed.

The researchers said that this time the glaciers collapsed in the Patagonia Ice Sheet was actually a reflection of climate warming. This year, the region has seen unusually high temperatures of up to 15°C. In addition, warm tropical air has brought a lot of rainfall to the region, which is also the reason for the collapse of the glaciers in the Patagonian Ice Sheet.

Similar problems of melting and receding glaciers happen in glaciers all over the world. After all, climate warming affects the entire area. However, the temperature rise in different regions is not the same, therefore, the melting rate of glaciers is also different. As one of the places with the most glaciers in the world, Antarctica has become the focus of scientists' attention naturally.

Over the years, scientists have found that the melting rate of glaciers in Antarctica is also quite alarming when they have studied the glaciers in Antarctica. Among them, the status of Thwaites Glacier, known as the "doomsday glacier", is not optimistic and it is in danger.

According to a paper published in "Nature Geoscience", scientists have drawn a map of the glacier's melting history to speculate on the future evolution of the glacier. It was found that under the influence of climate warming, the bottom of Thwaites Glacier, the "doomsday glacier", is being eroded by warm currents and is now rapidly melting at a rate of about 2.1 km/year. This is twice the rate of ablation that scientists observed 10 years ago.

In some previous studies, researchers have realized that a protective ice shelf on Thwaites Glacier is possible to collapse within five years, and if the ice shelf does, it will exacerbate the West Antarctic ice sheet’s instability.

Thwaites Glacier is the widest glacier in the world, according to Ted Scambos, US lead coordinator for the International Thwaites Glacier Collaboration (ITGC). If this glacier disappears and affects surrounding glaciers, it could cause sea levels to rise by around 3 meters.

With the affection of climate warming, glaciers all over the world are now melting to varying degrees. In some places, the rate of glaciers is relatively slow, and in other places, the rate of glaciers may be beyond your imagination.

If these glaciers can’t stop melting at a rapid rate, there will soon be fewer and fewer glaciers on Earth. According to some scientists' predictions, there may be an "ice-free summer" in the Arctic Ocean not long from now, that is, at some point in the future, the summer in the Arctic Ocean may be no sea ice.
