In Antarctica there are, in addition to mountaintops and nunataks, other natural snow- and ice-free areas often referred to as "Antarctic oases" or "dry valleys". [1] [2] These areas are surrounded by the Antarctic ice sheet or, in coastal areas, are situated between the ice sheet and the Antarctic ice shelves.
The Dry Valleys are so named because of their extremely low humidity and lack of snow or ice cover. They are also dry because, in this location, the mountains are sufficiently high that they block seaward-flowing ice from the East Antarctic Ice Sheet from reaching the Ross Sea. At 4,800 square kilometres (1,900 sq mi), the valleys constitute ...
<p>Chances are you make it through most days without sparing a thought for Antarctica. At just over 5.4 million square miles, it's a massive chunk of land that is nearly twice the size of ...
Study of the geology of Antarctica is hampered by the widespread ice cover The bedrock topography of Antarctica (with the ice cover digitally removed), critical to understanding the motion of the continental ice sheets Antarctica without its ice cover. This map does not consider that sea level would rise because of the melted ice, or that the ...
Antarctica’s vast expanse of sea ice regulates Earth’s temperature, as the white surface reflects the Sun’s heat back into the atmosphere. Record low sea-ice levels around Antarctica ...

[74] [75] [76] According to one study, if the Paris Agreement is followed and global warming is limited to 2 °C (3.6 °F), the loss of ice in Antarctica will continue at the 2020 rate for the rest of the 21st century, but if a trajectory leading to 3 °C (5.4 °F) is followed, Antarctica ice loss will accelerate after 2060 and start adding 0.5 ...
