MORE than two billion tons of ice at the North Pole and South Pole melt since 2003. Results of measurement data using satellite observations GRACE NASA property is the latest evidence shows the impact of global warming.
“Between Greenland, Antarctica, and Alaska, the ice layer of sea water has increased as fifth inches in the last five years,” said Scott Luthcke, geofisikawan NASA.
From these measurements, more than half of which is ice in Greenland before. During the past five years, the ice melt from Greenland are flowing to the Chesapeake Bay and the flow to the high seas. In fact, according to Luthcke, melting ice in Greenland will be faster.
Ice melted on land is actually no direct effect on the increase of sea water in the face of all the world like mencairnya frozen sea. In the 1990s, the ice in Greenland does not cause the increase of sea water, which means.
“However, at this time Greenland consecutive half-millimeter increase the level of sea water per year,” said NASA ice scientist Jay Zwally. “The continued worsened. This shows a strong sign of the distribution and amplification. There is no improvement occurs, “continued Zwally.
NASA scientists presented their findings on the new American Geophysical Union conference in San Francisco last week. By analyzing the changes in climate, in general, scientists will see that happen a few years to determine the overall trends.
