How the climate has been changing our planet in the course of 20 years (VIDEO)
Since 1997 NASA has been continuously documenting all the changes on our planet. Satellites have been observing life at the surface of the land and ocean for years.
This video demonstrates how dramatically the size of glaciers and snow cover on the Earth changed. So, due to the temperature increase, the Arctic has become more green over 20 years. Also there are tragic “biological emptiness” on our planet — these are places with almost no living creatures.
NASA hopes that this visualization will make people think about the importance of solving environmental problems.
