根据“At present, this continent holds about 26.5 million km² of ice. However, nearly one- fifth of the total Antarctic ice sheet surface had experienced observable melting during the past two decades, according to a report released by China's MOST this year.”可知,目前,这片大陆上约有...
The continent is divided into two regions, known as East and West Antarctica. East Antarctica makes up two-thirds of the continent, and is about the size of Australia. Ice in this part of the continent averages 1.2 miles (2 kilometers) thick. West Antarctica, on the other hand, is a ...

The majority of researchers estimate the substance balance in the antarctic ice sheet as close to zero (until more exact data are obtained). The areas...
