The Arctic is abnormal? The latest satellite images show that large cracks have appeared, or One divides into two.

Interesting news exploration often focus on foreign weather friends may know, due to the recent Arctic vortex fission effect, strong cold air swept across the United States, to minus 50 degrees Celsius cold weather in the United states. The extreme weather that the earth changes have affected our Arctic. Recently, scientists found that the Arctic is abnormal.

In the past few years, located in the Arctic northwest Greenland glacier has been the most famous Biderman scientists focus on the observation object.In July 21, 2012, the United States Air Reconnaissance Satellite found an area of 70 square kilometers of icebergs have to flow from the Biderman glacier, Biderman Fjord direction. Because of its shape like tongue, the scientists call it "tongue".

In July 31, 2018, when the United States returned to satellite observations of the Petermann glacier, found the Petermann glacier abnormal situation, a huge crack appeared on the glacier. This shows that in the near future this iceberg might at some time free from the glacier, One divides into two. tongues as before, again into the sea.

Niklas Neckel through the comparison of glaciologists in recent years, many satellite images found in the Petermann glacier ice flow has been accelerated. The winter 2016 of the Petermann glacier velocity is about 1135 meters per year, compared with the winter 2011 flow rate, velocity increased for about 10%.

Even the scientists Neckel also ask yourself, what is the reason for the Petermann glacier flow speed? Some people may think that the Arctic glaciers melting caused by global warming is responsible for speeding up the Petermann glacier velocity, but in fact, the real reason is not to let the Petermann glacier speed. According to the AWI led a new study that ice flow acceleration is due to the 7 month 2021 years lost "tongue" caused by.Scientists from AWI MartinR ckamp that said, if a major icebergs broke off from a glacier tongue at the end, it will reduce the overall length of the Petermann glacier, the glacier ice friction is reduced, thereby increasing the flow speed.

Although the north and south pole is the most cold, but in recent years by the impact of global warming, the Arctic ice melting faster, it is possible in the near future, the Arctic glaciers may not exist, a green shoots from the bare ground, become a beautiful scenery in the world. Maybe humans because of climate change started from the equator to the poles to evacuate the hot.
