NASA says Antarctic sea ice has INCREASED since 1970s
SEA ice around the south pole has INCREASED in volume over the past 40 years, a NASA study has found.
The Antarctic appears to have been proofed against global warming.
A NASA spokesman said: “Why has the sea ice cover surrounding Antarctica been increasing slightly, in sharp contrast to the drastic loss of sea ice occurring in the Arctic Ocean? A new NASA-led study finds the geology of Antarctica and the Southern Ocean are responsible.”
A NASA and National Oceanic and Atmospheric Adsministration (NOAA) team led by Son Nghiem of NASA’s Jet Propulsion Laboratory, Pasadena, California, used satellite radar, sea surface temperature, land form and bathymetry (ocean depth) data to study the physical processes and properties affecting Antarctic sea ice.
Mr Nghiem said: “Our study provides strong evidence that the behaviour of Antarctic sea ice is entirely consistent with the geophysical characteristics found in the southern polar region, which differ sharply from those present in the Arctic.”
