By creating a island It usually takes centuries or even millennia of the movement of huge tectonic plates, the situation now seems to have changed because of the climate change that now affects all countries of the world, some less, some more. The melting of the ice in the Alaska However, it is a phenomenon that has attracted the interest of experts.
The land area of the two square miles (about 5 sq. Km), known as Prop Knob, was an earlier part of the Alsek glacier in Alaska. However, NASA found that it is now completely surrounded by water, cut off from ice, thus creating an island.
Essentially, a picture taken by the satellite Landsat 8 in August shows that Prop Knob has lost any contact with the glacier and according to Nasa Earth Observatory, its conversion On the island it probably happened between July 13 and August 6th.
NASA attributes the Rapid change in climate change and global warming. The global warming and the increase in greenhouse gases appear to have destabilized the glacier.
Scientists have, of course, warned that ice melting can cause catastrophic floods.

As glaciers are melting, Waters are concentrated in cavities previously occupied by the ice, forming huge lakes. Many of them are held only by fragile natural natural barriers and ice.

The accelerated recoil of the glaciers that are located in the area exposed an unexpected geological finding.

NASA’s Earth Observatory has announced that Alaska has a “brand new island” after a retreating glacier lost contact with the Prow Knob mountain landmass in Alsek Lake. https://t.co/U8Wcx1wOq5

If they retreat, a wave of water and loads of materials may roll at speeds of 30-100 km/hdestroying everything in its course.
A recent study warns that 10 million people around the world are at risk of catastrophic floods From ice melting.
