Earth is losing sea ice at a rate of 25 square kilometers per year - VIDEO The increase in the extent of sea ice in the Antarctic does not overlap accelerate the decline of the ice cover of the Arctic, NASA scientists have found. On average, since 1979, the planet is losing sea ice at a rate of 25 square kilometers per year.
Surrounding the Antarctic sea ice reached 19 September 2014 a new record coverage area - more than 20 million square feet. km. However, the positive dynamics of growth of the Antarctic ice can not neutralize the rapid loss of sea ice in the Arctic.
"Although the Antarctic ice and reached a new record high in September last year, the global volume of sea ice continues to shrink," - said Claire Parkinson, author of the study and climate scientist from the center of Space Flight. Goddard. Analysis of satellite data showed that the dynamics of the total area of sea ice was negative in all months of the past year, even when the distribution of Arctic and Antarctic ice peaked.
Moreover, the global decline in ice speed up in the first two decades of observations (1979-1996 years) ice shrinking at a rate of 21.4 thoUSAnd square kilometers per year. These rates have doubled in the 1996-2013 years, when the average volume of melting ice was 50.5 square kilometers per year.
Parkinson believes that the increase in Antarctic sea ice is unlikely to accelerate enough to ensure the increase in the area of ice in the world. Rather, says climatologist, the rate of increase of Antarctic ice to slow down, and the area of its distribution will decline.
