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).
Starting on December 15, she fought through temperatures as low as -4 degrees Fahrenheit (-20 degrees Celsius) and winds as strong as 50 miles per hour (about 80.5 km/h) – moments in which ...
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.
The 2024 Antarctica heat wave refers to a prolonged and significant mid-winter increase in Antarctic temperatures compared to prior winters, causing several regions of Antarctica to reach temperatures 10 °C (18.0 °F) above normal in July 2024, up to a 28 °C (50.4 °F) increase above average. The heat wave was significant for occurring during ...
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 ...
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 ...
By 2009, researchers were able to combine historical weather-station data with satellite measurements to create consistent temperature records going back to 1957 that demonstrated warming of >0.05 °C/decade since 1957 across the continent, with cooling in East Antarctica offset by the average temperature increase of at least 0.176 ± 0.06 °C ...
