Nearly all of Antarctica is covered by a sheet of ice that is, on average, at least 1,500 m (5,000 ft) thick. Antarctica contains 90% of the world's ice and more than 70% of its fresh water. 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]
Also on June 5, 1968, Plateau station had -123.0 °F (-86.1 °C). The maximum temperature on July 20, 1968 was −80 °C (−112 °F). The average temperature of the cold season (from April to October) is about −70 °C (−94 °F), while the average temperature of the warm season (from November to March) is about −40 °C (−40 °F).
Weather instruments such as this device installed upon Iceberg B-15A provide scientists a better understanding of Antarctica's impact upon global climate. Polar winds are a driving force behind weather systems arising from three surface zones that converge at McMurdo Sound: the polar plateau and the Transantarctic Mountains , the Ross Ice Shelf ...
The highest temperature ever recorded at McMurdo was 10.8 °C on December 21, 1987. There is enough snowmelt in summer that a few species of moss and lichen can grow. The average yearly temperature is freezing, but it can get as high as 8°C (46°F) in the austral summer and as low as -50°C (-58°F) in the austral winter.

According to the World Meteorological Organization in Geneva, the new record high temperature on continental Antarctica is a downright pleasant 63.5 degrees Fahrenheit (17.5 degrees Celsius). The ...
The climate of the Schirmacher Oasis is relatively mild for Antarctic conditions.The annual average temperature is −10.4 °C (13.3 °F) (ranging from 0.9 °C (33.6 °F) in summer to −22.0 °C (−7.6 °F) in winter), [2] the annual average wind speed is 9.7 m/s (22 mph; 18.9 kn), the annual average precipitation is 264.5 mm (10.41 in), and there are 350 hours of sunshine per month.
The maximum recorded at Concordia on 17 March was -16.9 °C Pending the final data, in Vostok the value of -20.3 °C set the new monthly record but also exceeds the maximum of February (-22.2 °C ...
