NASA Research Indicates Slow, Irreversible West Antarctic Ice Melt

New research from NASA indicates an unstoppable chain reaction of Antarctic ice melt in the Amundsen sea

Bad news for Antarctic ice, but not particularly surprising to scientists Several news headlines this week have heralded the “unstoppable” decline of a major portion of the West Antarctica ice sheet in the Amundsen Sea, eventually disappearing in as little as two centuries. Projections for the complete collapse of the West Antarctic ice sheet range from two hundred to nearly nine hundred years, but what is clear is that …

Video Friday: Growing Concern Over Sea Level Rise

growing concern from scientists studying the Greenland and Antarctica ice sheets over the potential for sea level rise

From the Yale Climate Forum. Scientists studying the Greenland and Antarctic ice sheets express growing concern over the fragility and vulnerability of the world’s ice sheets and the potential impact on sea level rise. Researchers in Antarctica are using sophisticated equipment to drill down 500 meters below the ice shelf to measure ice loss, temperature, salinity and speed of melt. In one location measured …

Antarctic Warming Shows “Human Fingerprints”

The rapid ice melt and temperature rise in the Arctic region has been widely reported, with a record summer ice melt occurring last year in the Arctic ocean, and a near-record this year (the volume of sea ice, if not the extent, did reach a record low this year, with autumn temperatures in the Arctic 9 degrees Fahrenheit above normal). The February 2007 report …
