The area of an ice cover in Antarctic record-breaking decreased


In December the area of ice was reduced on 253 thousand square kilometers a day. Speed of loss of ice set a record for all history of satellite observations. As of January 1, 2019 the area of the Antarctic sea ice decreased to 5.47 million square kilometers. It is a record minimum for this date in 40 years of satellite observations, reports N 1 with reference to data of the National center of information on snow and ice of the USA (NSIDC) on Wednesday, January 9. It is noted that as the summer season of thawing of ice will proceed one and a half-two more months, its area can update also a record of an annual minimum. According to department, for January 1 the area of sea ice in Antarctic was on 30 thousand square kilometers less previous record, established on January 1, 2017, and on 1.88 million square kilometers there is less average value for 1981-2010. In December, 2018 the area of the Antarctic sea ice was reduced on 253 thousand square kilometers a day that significantly quicker, than on average for this month. Ice loss speed also set a record for all history of satellite observations. Experts also note that the area of an ice cover of the ocean in Antarctic very strongly fluctuates. In 2007 and 2014, on the contrary, maxima of the December area of ice were recorded. Therefore at the moment it is impossible to speak about any trend in change of an ice cover of Antarctic as a result of climate change. The reasons of so sharp reduction of the area of ice this year are still not clear. NSIDC reports that and - for suspensions of work of federal departments in the USA, habitual sources of data on atmospheric conditions in the region are inaccessible to them. Let's remind, in October, 2018 in the west of Antarctica from a glacier Pine-Aylend broke away a huge iceberg. By the sizes it is comparable to Kharkiv – the area of an ice floe is 300 square kilometers. News from the Correspondent.netv of Telegram. Subscribe for our https://t.me/korrespondentnet channel
