How thick is ice sheet
The Antarctic ice sheet is the largest single mass of ice on Earth. It covers an area of almost 14 million km (5.4 million mi ) and contains 30 million km of ice. Around 90% of the Earth's ice mass is in Antarctica, which, if melted, would cause sea levels to rise by 58 meters (190 feet). The continent-wide average surface temperature trend of Antarctica is positive and significant at >0.05 °C (0.09 °F)/decade since 1957. NettetIt has been estimated that during the Pleistocene, the East Antarctic Ice Sheet thinned by at least 500 m (1,600 ft), and that thinning since the Last Glacial Maximum is less than 50 m (160 ft) and probably started after ca 14 ka. [10] Territorial claims [ edit] Many countries hold a claim on portions of Antarctica.
