NASA research has shown a serious decrease in glaciers at the Earth's poles
Millions of tons of ice disappear at the Earth's poles every year, resulting in rising Oceans levels.
The relevant video was published on the website of the U.S. National Aerospace Agency (NASA).
The video showed changes in the Earth's ice cover over the last 16 years using data from the ICESat-2 satellite.
The satellite uses a laser altimeter to send a 10-kilohertz pulse to Earth. For example, between 2003 and 2019, the loss of ice in western Antarctica caused Oceans levels to rise by 14 millimeters.
This is slightly less than one-third of the total water rise observed in the world's oceans. In the eastern part, on the contrary, glaciers have increased.
In total, due to global warming, about 200 million tons of ice disappear annually in Greenland and 118 million tons in Antarctica.
