Antarctic summer for 60 years has been long almost twice

The period of melting ice in the Antarctic Peninsula lengthened over the past 60 years, almost twice, according to a study published in the Journal of Geophysical Research.




Scientists from the British National Centre for Antarctic Studies (BAS) studied the history of ice melting on the Antarctic Peninsula, which is global warming effect is stronger than the rest of the continent and is the most serious loss of ice. They analyzed the results of meteorological observations made at the 30 polar stations Peninsula since 1948, as well as maps of melting ice, compiled from satellite data 1999-2009.

"Over the past 60 years, the summer season is longer — as suggested by data from all 30 stations. On one of them the period with temperatures above zero has almost doubled in the period from 1948 to 2011, and continues to lengthen," — said the head of research Barrande Nick (Nick Barrand).

According to meteorological data, in Antarctica is stronger than in other regions of the world shows global warming. According to the results of previous studies BAS, average annual temperatures in Antarctica have risen since 1950 by three degrees Celsius — that's three times more than the global average. According to the calculations of climate scientists over the past 20 years, the planet's southern ice cap has lost about 2.94 trillion tons of ice, resulting in a sea level rise of 1.1 cm.
