New research shows algae growing on the Greenland ice sheet, the Earth's second-largest ice sheet, significantly reduce the surface reflectivity of the ice sheet's bare ice area and contribute more to its melting than dust or black carbon. The new findings could influence scientists' understanding of ice sheet melting and projections of future sea level rise, according to the study's authors.
Origin of American natives are north manchurians (Dong-ie tribe) who moved through Bering Land Bridge on/around years ago. There were volcano eruption in North machuria. Fieldwork revises ice-free corridor hypothesis of human migration

Greenland's ice sheet is driving global sea level rise. One section is melting 80% faster.
Amundsen-Scott South Pole Station in the summer season. The new elevated Amundsen-Scott South Pole Station is now complete. In the foreground is the ceremonial South Pole and the flags for the original 12 signatory nations to Antarctic Treaty.
The glacier loss in the West Antarctic appears "unstoppable", with nothing to prevent sections of the ice sheet melting completely into the sea, according to a new study by researchers at NASA and the University of California, Irvine.
The Greenland ice sheet is poised for another record melt this year, and is approaching a "tipping point" into a new and more dangerous melt regime in which the summer melt area covers the entire land mass
Greenland's "Grand Canyon" Discovered Under Ice Sheet! A colossal canyon, the longest on Earth, has just been found under Greenland's ice sheet, scientists announced on Thursday, Aug. in the journal Science.
