Arctic ice

Arctic ice is in the top of a smaller and more sparse than the previous, while older ice is replaced starting a powerful young ice melt that fast. Said some researchers in the NASA and the National Snow and Ice Data Center in Colorado.

According to the researchers, the maximum sea ice in the winter Artik this increase 15 million and 150,000 square kilometers, about 720,000 square kilometers less than the average area between the North Pole in 1979 and 2000.

In the normal winter, ice thickness often have three or more meters, however, this year, de-ice thickness almost can not penetrate the appropriate target "Arctic Circle".

"We are not ready for the summer. We are in a very precarious situation," said the scientist's Ice Data Center, Walt Meier.

Number of thick sea ice reached lower levels in the winter with a 680,400 square kilometers this year, down 43 percent from year ago.

"Usually, the ice is thinner and younger was 70 percent of the ice layer. This year, a layer that reached 90 percent," said Meier.

"Ice is very important because the sea reflect the sun from Earth. The more ice to melt, the more heat be merged by the ocean so that hot temperatures on the planet," said Program Manager NASA Polar Regions Tom Wagner.

Heating also can change the climate patterns around the world and the ecosystem change for animals like polar bears.

Meanwhile, the South Pole is also the condition of concern. A shelf of ice was lost quickly, missing one start and glacier melt faster than expected due to all the climate change, expressed by some researchers as the UK and the U.S. Government on 3 April.

They said "Wordie Ice Shelf," which has been split since 1960s, and lost the north "Larsen Ice Shelf" is no more. More than 8300 square kilometers have been separated from "Larsen Shelf" since 1986.

The causes of climate change. Therefore the contents of the report "U.S. Global Survey (USGS) and the" British Antartic Survey "
"Glacier shrinkage in there quickly to show once again the real impact is being experienced by our planet, faster than expected, as the impact of climate change," said Minister of Home Affairs U.S. Ken Salazar in a statement.

"This ongoing and often a reduction in the glacier often with very large hail is warning that a change occurred ... and we need to prepare," said glasiologi USGS expert, Jane Ferrigno, who led the study Antarctica, in a statement.

"Antarctica has a special interest because it has as many as 91 percent of the volume of glacier in the Earth, and changes in any layer of ice on the cause of the threat to the community," he said.

In another report in a broadcast journal "Geophysical Letters", "National Oceanic and Atmospheric Administration" states, the ice melt much more quickly than estimated in the North Pole.

The report is based on the new computer analysis and measurement of ice has not been this long.

"UN Climate Panel projects that world temperatures will increase the atmosphere between 1.8 and 4.0 degrees celsius due out greenhouse gases, the condition can cause floods, droughts, heat waves and stronger storms.

While layers and glacier ice melt, the circumstances can raise the entire surface of the ocean water and soak lowland areas.
