McMurdo Dry Valleys, Landsat 7 imagery acquired on December 18, 1999 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
McMurdo Station briefly gained global notice when an anti-war protest took place on February 15, 2003. During the rally, about 50 scientists and station personnel gathered to protest against the coming invasion of Iraq by the United States. McMurdo Station was the only Antarctic location to hold such a rally. [25]
Antarctica's extreme remoteness and hazardous travel conditions limit Antarctica tourism to an expensive niche industry largely centered on the Antarctic Peninsula. The number of seaborne tourists grew more than four times throughout the 1990s, reaching more than 14,000 by 2000, up from 2,500 just a decade earlier. [ 18 ]
The latest data shows high temperatures in portions of East Antarctica – where the most abnormal conditions are ongoing – that are typically between minus 58 and minus 76 degrees Fahrenheit ...
Temperatures 70 degrees above normal in eastern Antarctica have baffled scientists, who say that the “unprecedented heat wave” has already changed the way experts think about the Antarctic ...

If all the land-ice covering Antarctica were to melt — around 30 × 10 ^ 6 km 3 (7.2 × 10 ^ 6 cu mi) of ice — the seas would rise by over 60 m (200 ft). [22] The Antarctic is so cold that even with increases of a few degrees, temperatures would generally remain below the melting point of ice.
Antarctica locks up 90 percent of the world's fresh water as ice and would raise sea levels by about 200 ft if it were all to melt. Antarctica hits record high temperature at balmy 17.5°C (63.5 ...
