Greenland:discovered a huge canyon beneath the Arctic ice!
Under the ice cap of over 2 km that covers Greenland, a team of scientists, through the development of countless satellite data has discovered a canyon that runs for almost 800 km from the center of the island at the mouth until the Arctic Ocean.
It seems that it is the result of an excavation carried out by the rivers of water flowing in a past time that is between 1 million to 3 million years ago, when the climate was much warmer on earth, and there was still ice cap.
This sensational discovery will have a major impact within the environmental climate models, since within this canyon run the immense masses of water in dissolution below the glacier from where they reach the Arctic Ocean going to affect appreciably the mass balances on the melting of ice and the rise of the oceans
