The scientist are concerning about the effects of the global climate change in the Polar Regions.
The observations are made from three European Space Agency satellites which are continuously observing more than 415,000 square miles or 1,075,000 square km from 18 years.
Up to 2003, the volume of decline of the Antarctic ice was meager, where at one side West Antarctica losing out and the East Antarctica gaining the ice balancing the overall volume, but after 2003, the West Antarctica is losing and the East is not gaining.
Glaciologist Helen Fricker of the Scripps Institution of Oceanography at the University of California, San Diego said, “There has been more and more ice being lost from Antarctica’s floating ice shelves.”
Scripps geophysics doctoral candidate Fernando Paolo said, “If the loss rates that we observed during the past two decades are sustained, some ice shelves in the Amundsen and Bellingshausen seas could disappear within this century.”
The scientists say that the melting of the ice shelves does not directly affect sea level because they are already floating.
Paolo added, “This is just like your glass of gin and tonic. When the ice cubes melt, the level of liquid in the glass does not rise.”
The floating ice shelves provide restraining force to land based ice and the reduction in land based ice would cause the ice from land into ocean increasing the sea levels.
Fricker said, “While it is fair to say that we’re seeing the ice shelves responding to climate change, we don’t believe there is enough evidence to directly relate recent ice shelf losses specifically to changes in global temperature.”
