It is getting longer and longer. Songdao Glacier has added 20 kilometers of cracks, and the ice loss rate exceeds 10 meters per day.

The impact of the earth's climate change on the North and South Pole is also gradually emerging. Although we personally feel that these two regions are far away from us, However, with the destruction of the earth's ecosystem by humans, changes have occurred on a global scale, and more and more "chain effects" of global warming have appeared. According to a new scientific report from the European Space Agency, the new cracks in Pine Island Glacier have undergone tremendous changes and are getting longer, which will have a huge impact on the overall condition of the glacier. If the glacier breaks, it will make a new contribution to sea level rise and the climate will become "negative".

According to scientific reports, the evolution of two major fissures in the Pine Island Glacier in Antarctica has grown rapidly by about 20 kilometers since the beginning of 2019. Its rapid thinning and accelerated melting are worrying. . Scientists are also analyzing some of the reasons, but they have given clear explanations. The melting of parts of Songdao Glacier will directly lead to sea level rise. Near Pine Island Glacier, scientists also discovered a huge floating ice shelf support, which itself is thinning and lost a huge iceberg in late 2018.

Everyone who has read the report knows that the iceberg is the large iceberg labeled "B46" by scientists, with an area of ??approximately 87 square miles. In early 2019, shortly after B46 left the ice sheet, scientists discovered additional large cracks in the glacier, which are further changing the glacier conditions across Antarctica. According to the European Space Agency, the Pine Island Glacier ice shelf is now one of the fastest losing ice shelves in Antarctica, with ice velocity increasing dramatically to more than 30 feet per day since the early 1990s.

So very quickly, this is the result of global climate change. If all the glaciers in the Arctic and Antarctic are lost, then basically many areas will be unsuitable for human habitation, because according to the basic climate In principle, the North and South Poles actually have a certain impact on the airflow. Otherwise, the earth would not be able to experience seasonal changes. In addition, without their existence, how can we integrate a stable climate phenomenon? This is also the reason. Some people have previously It is said that the earth may have a climate like "Mars" in the future. Of course, this statement is not necessarily accurate, but the climate is more severe.

Back to the above, the sea level problem caused by glacier loss. According to early scientific reports, let’s not say that all the glaciers in the Arctic and Antarctic have melted. We can’t stand the melting of the glaciers in Greenland alone. According to data estimates, if all the glaciers melt, the global sea level will rise. It will rise by 23 feet, which can be said to be a very "negative" figure. How many cities will be submerged by 7 meters? It is estimated that cities close to the coast will be difficult to avoid being submerged in some areas. At the same time, islands with lower sea levels will basically be submerged. It’s gone.

After reading these, the closest thing to us may be the change of extreme weather. This year, rare high temperatures have appeared around the world. The highest temperature we have heard may be the "high temperature around 50 degrees" in India. If I lived in such weather conditions, I would basically not dare to go out, not to mention other problems. Therefore, if we continue to worsen the earth and global warming continues, extreme weather changes such as high temperature, drought, and rainfall will occur. , will also make our lives more difficult, and secondly, the intensity of storms in ocean areas will reach a new height.
