NASA study shows Antarctica gaining ice in some regions
Published research concludes that Antarctica ice melt is not contributing to rise in sea level
A recent NASA study shows that global warming did not cause Antarctica ice melt loss over a nine year period between 1992 and 2001, during which the continent actually gained more than 110 billion tons of ice every year. The study, which appeared in the Journal of Glaciology, also reported that the amount slowed to 80 billion tons of ice a year between 2003 and 2008, but the gains have not been consistent around the continent.
According to the study results, there was a loss in ice in the area of the Antarctic Peninsula, as well as in the West Antarctica in the area of the Thwaites and Pine …show more content…
Core samples were used to study snowfall from the past 10,000 or more years, which showed the East Antarctica ice thickness has been increasing for quite some time, regardless of global warming predictions. They concluded that this increase was due to the air becoming warming and carrying more moisture into the area after the last Ice Age. Climate changes, resulted in twice as much snow falling onto the ice, which then was compacted down to form new ice.
Ice gains keep Antarctica from contributing to rises in sea level
The report showed that despite global warming, Antarctica isn’t contributing to any rises in sea level and is actually lowering sea level by 0.23 millimeters a year. The NASA study challenges findings such as those of the UN Intergovernmental Panel on Climate Changes that claims Antarctica is losing land ice. This NASA study disagrees with those conclusions. However, discrepancies may occur due to the difficulty of measuring the continent.
Other studies have showed that ice in both the Arctic and in Greenland is freezing at historic levels, which could explain why the sea level rise hasn’t been as high as some organizations have predicted. It has also been shown that Greenland glaciers are receding, which is attributed to global
