The Antarctic ice sheet is a continental glacier covering 98% of the Antarctic continent, with an area of 14 million square kilometres (5.4 million square miles) and an average thickness of over 2 kilometres (1.2 mi). It is the largest of Earth's two current ice sheets, containing 26.5 million cubic kilometres (6,400,000 cubic miles) of ice ...
The climate of Antarctica is the coldest on Earth. The continent is also extremely dry (it is a desert [ 1] ), averaging 166 mm (6.5 in) of precipitation per year. Snow rarely melts on most parts of the continent, and, after being compressed, becomes the glacier ice that makes up the ice sheet. Weather fronts rarely penetrate far into the ...
Climate change in Antarctica. Antarctic surface ice layer temperature trends between 1981 and 2007, based on thermal infrared observations made by a series of NOAA satellite sensors. Climate change caused by greenhouse gas emissions from human activities occurs everywhere on Earth, and while Antarctica is less vulnerable to it than any other ...
Evidence from a 2,000-foot-long ice core shows rapid past melting — a stark warning for potential sea level rise as temperatures soar
The East Antarctic Ice Sheet ( EAIS) lies between 45° west and 168° east longitudinally. It was first formed around 34 million years ago, [ 3] and it is the largest ice sheet on the entire planet, with far greater volume than the Greenland ice sheet or the West Antarctic Ice Sheet (WAIS), from which it is separated by the Transantarctic ...
The Filchner ice shelf is the eastern part of the Filchner–Ronne ice shelf. It is bounded on the west by Berkner Island and on the east by Coats Land. The east part of this shelf was discovered in January–February 1912 by the German Antarctic Expedition under Wilhelm Filchner. Filchner named the feature for Kaiser Wilhelm, but the Emperor ...
Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14,200,000 km 2 (5,500,000 sq mi). Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km (1.2 mi).
The hole in Earth's ozone over Antarctica is the smallest we've seen since 1988 — but don't get too excited. The whole in Earth's ozone over Antarctica decreased in size Skip to main content
