Artificial snow could save the Antarctic ice

Artificial snow could be used to stabilize the West Antarctic ice cover, according to scientists from the Potsdam Institute for Climate Research (PIK).

The billions of tons of snow surplus would be achieved by pumping ocean water into the glaciers and spreading it with snow cannons.
This operation would require unprecedented engineering work. As this is one of the last untouched areas in the world, the intervention would also pose a significant environmental risk, wrote
This would prevent a long-term rise in sea levels in many very high population density areas of the world from the United States to China.
“The fundamental question is whether humanity is sacrificing the Antarctic to save the cultural heritage that we have built and built in coastal towns. It is the largest metropolis in the world from New York to Shanghai, which is under water if we do nothing” – said Anders Levermann, physicist at PIK and Columbia University, an author of the study.
“The fate of the West Antarctic Ice Cream (WAIS) is a key issue for the Earth’s climate.
The warm ocean currents reached the West Antarctic Amundsen region, home to many glaciers that are labile due to their topography. Their underwater melting accelerated the shrinkage of ice currents.
At the moment, the continent’s ice melting is the most serious, contributing increasingly to world sea levels.
“With our models we have been researching how to prevent the ice field from collapsing and increasing snowfall in this very labile area. to blow snow a few hundred billion liters of water in a few decades, “he added.
In order to lift and desalinate sea water and operate snow cannons, the energy of tens of thousands of modern wind power plants would be needed.
“If we were to build this huge wind turbine farm and all the other infrastructure in the Amundsen Sea and pump out a lot of sea water, it would destroy this unique, untouched natural value. Because of the harsh Antarctic climate, it is difficult to predict technological difficulties,” he explained.
“The study did not take into account the future global warming caused by human activity, so it would only make sense for this huge company to comply with the Paris Climate Convention and to reduce carbon emissions quickly,” Feldmann said.
