Antarctic ice sheet melting fast scientists from several international laboratories observed the fast melting of the ice sheet that forms in the Arctic Ocean, known as the Greenland and Antarctic ice sheets.
The rapid melting of Greenland ice sheet ice in summer is the latest result of the 세종출장안마rapid sea level rise in the past decade or so as Earth’s oceans have taken on greater water.
Scientists who monitored the changes in Greenland ice sheet from space had to overcome extremely steep cliffs which protect the ocean floor, and the harsh temperatures in their i제천출장마사지nstruments.
“I am very happy this time to report that the Greenland ice sheet, which forms part of the ice sheet called the West Antarctic ice sheet in summer, melted in Summer 2010 for the first time since 1979”, said Dr Michael Mann from the NASA Goddard Institute for Space Studies (GISS) at Columbia University, who led the study published today in Geophysical Research Letters. “It was very interesting to observe such rapid ice loss while observing a very steep cliff on Greenland and the impact of these cliffs on the ice sheet.
“Because of the steep cliffs on Greenland ice sheet, the glacial meltwater must be flowing rapidly towards the ice cap, so this is a problem that we cannot solve. We need to keep an eye on this water.”
A team of scientists from the US National Snow and Ice Data Center (NSIDC) and from the Universities of Bristol, France and the United Kingdom had been studying Greenland ice sheet loss for some time now.
The NSIDC team discovered two glaciers flowing directly into the sea and the ice sheet losing up to 200 metres of ice per hour (m/h) per month over the course of a year with the last glaciers retreating the other day. It was these glaciers that the other team was focusing on during their field study on the gla강원출장안마 강원출장샵cier of Larsen B.
Dr Michael Mann from the NASA Goddard Institute for Space Studies (GISS) said: “The two glaciers on Greenland show a remarkable and rapid disappearance of ice. This is happening with huge acceleration and could accelerate the rate of melt in the coming decades.
“This rapid melting is a problem for several reasons. First, the fast melting of Greenland ice is a result of the fact that it is a particularly fast growing ice sheet which has grown fast in the past few centuries, creating and growing faster areas that can melt and release huge volumes of meltwater to the atmosphere.
“When it is extremely warm enough, melting of West Antarctic ice sheets can easily exceed 20 m/h/year
