NASA scientists in the course of the study found that as a result of global warming, the ice sheets of Greenland and Antarctica are melting too quickly. This could lead to a 38 cm rise in sea levels by 2100.

Scientists have found that Greenland's large ice sheet is capable of adding 8-27 cm to sea level by the end of the century. And Antarctica's ice sheets will cause an increase of 3-28 cm by 2100. During the study, researchers found that over the 20th century, the level of the world's oceans increased by about 15 cm. At the moment, the process has accelerated by 2 times. With the help of new data, the experts succeeded in quantifying the melting of the “Doomsday glaciers”. “The most important thing is to find out how much sea level will rise in the future. It is important to understand how the ice sheets will contribute to this, ”said Sophie Nowitzki, who is the project manager.
During the study, the specialists artificially created an environment with a minimum level of emissions. The Greenland ice sheet showed that the global sea level rise increased by 3-9 cm. Analyzing the process in Antarctica is more difficult. According to scientists, it should not be ruled out that emissions will lead to a “decrease” in the water level. But experts say that its increase, apparently, is inevitable, but with the new information we will be able to direct our efforts in the right direction and understand what needs to be worked on to continue improving forecasts.
