Layers West South Pole Unstable

Warming the Earth's southern hemisphere is currently estimated to affect the ice at the South Pole or Antarctica. Team of researchers at Oxford University and Cambridge University, England, recently revealed the results of studies that claim the west Antarctic ice sheet began to unstable. The team developed a model to explore the changes in ice cover from the basic to the floating layer.

"The volume of ice contained in a layer of western Antarctica is equivalent to 3.3 meters of sea level rise," said Dr. Richard Katz of the Department of Earth Sciences University of Oxford. The model developed showed instability at the base line caused by gradual climate change. This can lead to disunity ice.

"Global climate models are often used assumption that when the world warms, the ice sheet will melt with stable, then cause a gradual sea level rise," said Katz.

But, he said, the structure of ice is much more complex. "We need to do more work to build better models of ice sheet behavior. Then to predict the behavior of ice in the future as the impacts of climate change," said Katz.
