Researchers studying climate change in Antarctica, recorded the presence of unusually warm water under a glacier, whose dimensions correspond to the size of the U.S. state of Florida. According to the article from the publication the New York Times, the water temperature at the base of the Thwaites glacier is two degrees Celsius above the freezing point, thereby creating the danger of rapid melting of the ice of centuries of education and increase of level of world ocean. What else will be faster formed lake under the ice of Antarctica and whether we can interfere with that process?
Melting glaciers Antarctica
Scientists have long warned about the dangers of melting glaciers in Antarctica, can cause the flooding of several major coastal cities around the world. The system of the ancient southern glaciers including the Thwaites, acts like a brake that protects us from the sharp increase of level of World ocean, which, rising more than a meter, would be significantly changed the map of the world. In order to observe the activity under the glacier, a team of scientists, led by Dr. David Holland of the Thwaites Glacier Collaboration, the drilled hole from the surface of the glacier to the very bottom, and then launched an equipment that measures the temperature and Miscibility salty ocean water with fresh water.
In total the drilling of a 600-foot bore took 96 hours of work in sub-zero temperatures, however, the results of the experiment showed that fears of climate scientists about the dangers of global warming are justified.
Despite the fact that scientists cannot accurately predict how soon the glaciers like Thwaites, finally melted, it is clear that the main reason for the change in the total area of ice on the planet is anthropogenic human activities. So, it depends on us how soon to dive under the water such metropolises as new York, Saint Petersburg, Amsterdam, Barcelona and Yokohama.
