Antarctica’s ice sheet and The Landscape Below

Aerial view of rugged mountainous terrain with glacial water in between the peaks.

A groundbreaking new map offers an unprecedented glimpse beneath Antarctica’s ice sheet, revealing the continent’s hidden topography with remarkable precision. This high-resolution terrain map, known as the Reference Elevation Model of Antarctica (REMA), was released by researchers at the National Geospatial-Intelligence Agency in September 2018. The REMA provides detailed imagery down to the size of a car in some areas, […]

Life of Penguins

When an El Nino hits, the lives of penguins are in peril.  During the 1997 El Nino the penguin population fell by a third. During Climate Change a difference in temperature of at least one degree can be a life and death situation for penguins.  Researchers followed a group of about 15 breeding penguins from 1992 to 2010 on the […]

Antarctic ice sheet is more vulnerable to carbon dioxide than expected

Results from a new climate reconstruction of how Antarctica’s ice sheets responded during the last period when atmospheric carbon dioxide (CO2) reached levels like those expected to occur in about 30 years, plus sediment core findings reported in a companion paper, suggest that the ice sheets are more vulnerable to rising atmospheric CO2 than previously thought. Details appear in two […]
