The largest glacier in the world is also one of the speediest. Combined with the Bagley Icefield, where the snow that feeds the glacier accumulates, the Bering is the largest glacier in North America. A temperate glacier (as opposed to a polar glacier) is a glacier that’s essentially at the melting point, so liquid water coexists with glacier ice. But glacier scientists at NASA have recently found that East Antarctica, too, is systematically shedding ice, if not as quickly as West Antarctica. As the world warms due to increasing greenhouse gases being added to the atmosphere by humans, the snow and ice are melting. The Rights Holder for media is the person or group credited.
