antarctica A lake covered with snow suddenly disappeared. Due to its sudden disappearance, 21-26 billion cubic feet of water flowed into the ocean. This incident happened in the Ameri Ice Shelf of East Antarctica in 2019. Scientists saw the lake disappear with the help of satellite. He found that in just three days it was found in the ocean.
Lead researcher in the study on this phenomenon and glaciologist Roland Warner at the University of Tasmania says that the weight of the water in the lake was so high that the ice broke. This is called hydrofracture. Because of this, the water flowed into the ocean. Studying such processes is not easy. Therefore, more information is needed about them.
risk of sea level rise
As the melting of lakes in Antarctica increases, researchers are concerned that it could increase the volume of water and see more hydrofracturing events. This can cause ice to collapse and sea level to rise. The team wrote in their study that the surface of the Antarctic could melt twice as much by 2050. This has also raised concerns about other ice shelves.
Earlier in the second study, scientists have warned that every year 53 thousand square km of ice is melting from the earth. Due to this, humans may have to face serious consequences in the coming time. He said that between 1979 and 2016, so much ice has melted that it can fill the huge Superior Lake.
Color changing snow, fast melting glacier, alarm bells!
