Scientists say the latest findings suggest that Arctic sea ice continues to shrink and thin

Arctic sea ice melted faster this year than ever recorded, according to the U.S. National Snow government and Ice Data Center (NSIDC).

satellite observations show the extent of floating ice that melts and freezes each year was 318.000 square miles less than last week in the period the same day in 2007, the year of registration of low-grade Observed and at this time of year since records began in 1979. Separate observations by researchers at the University of Washington suggest that the volume of Arctic sea ice is also the smallest ever calculated for this time of year.

careful, it's still early in the "melt season", but said the latest observations suggest the coverage of sea ice in the Arctic continues to shrink and thin and bottom annual enrollment pattern seen since 2000 is now well established. past year, the sea ice to melt on second record, 36% below the minimum average 1979-2000.

"The recent rate of ice loss were 100,000 to 150,000 square kilometers (38,600 to 57.900 square miles) per day, which is more than double the rate of climate. Although the measure is at its lowest level for date, it is still early in the melt season. changing weather conditions throughout the summer will affect the exact path of the extent of sea ice for the rest of the melt season, "said a spokesman of the NSIDC.

The increased melting is seen as a consequence of climate change. Arctic temperatures rose twice as fast as the global average over the past half-century.

speed record of melting ice in the Arctic this year coincide, but not necessarily related to heat waves in Siberia, record temperatures in the eastern U.S. and most of the time extreme ever recorded in the United Kingdom and Northern Europe. The relationship between melting Arctic ice and extreme weather in the northern hemisphere is not defined, but the Met Office in the UK and recent scientific reports have suggested that the decline of sea ice is associated with colder winters.

Aa marine biologists this month, said that Arctic warming could have ecological effects. Scientists funded by NASA working 100km from unfrozen water nearby in the journal Science that they had last year are abnormally high concentrations of microscopic phytoplankton - the base of the marine food chain - under the ice they describe as looking like a wild forest. So far, they had believed phytoplankton increased only in open waters.
