Greenland ice melted like never before

That is the result of research by scientists recently published in the journal Science (USA) on 13-11. According to scientists' conclusions, if Greenland's massive ice sheets melted due to global warming, Earth's sea level would rise by 7cm.

The speed of ice melted much faster, about 0.75mm / year in the period 2006-2008 compared to the rate of 0.46mm / year in the period 2000-2008.

Scientists survey the phenomenon of faster melting of ice in the west of Greenland.

These figures are calculated from two different measurement methods. One is to measure the difference between the total amount of snowfall and the total number of melting ice blocks in the Greenland island nation based on the regional computer model. The second is based on detailed observations of changes in Earth's gravitational field from Grace observation satellites. As a result, the values ​​of the two measurement methods are almost the same.

The surface of Greenland ice began to melt quickly around 2006, the snow falling on the ice sheet also increased by the same level, compensating for the loss of the ice surface volume for nearly a decade, moreover there was a quantity of water. Melted to freeze before falling to the ocean. Without these "moderate effects", the pace of ice decline in Greenland would probably double that of the current figure.

Professor Jonathan Bamber, working at Bristol University in England, said: 'These figures will be a good signal for the Climate Change Summit in Copenhagen, Denmark in December'.
