The Tsangpo River is the highest major river in the world, starting at 14,500 feet elevation and plunging to the Bay of Bengal, scouring huge amounts of rock and soil along the way. Yet in its upper reaches, the powerful Tsangpo seems to have had little effect on the elevation of the Tibetan Plateau.

New research that integrates seismic recordings with Global Positioning System (GPS) measurements indicates that a 7,000-square-mile region of the Whillians Ice Stream in West Antarctica moves more than two feet twice every day in an earthquake-like pattern equivalent to a Magnitude 7 temblor.

New research challenges the generally accepted belief that substantial ice sheets could not have existed on Earth during past super-warm climate events.
