Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−135.8 °F) on 10 August 2010, at . Although this is not comparable to an air temperature, it is believed that the air temperature at this location would have been lower than the official record lowest air ...
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]

Surface wind direction and speed is also forecast on this type of chart. Wave prognostic charts show the expected sea state at some future time. [2] Low-level prognostic charts used by aviators show the forecast between the Earth's surface and 24,000 feet (7,300 m) above sea level over the next two days.
Less than 10 percent of McMurdo Sound's shoreline is free of ice. [3] During austral winter, McMurdo Sound presents a large expanse of surface ice. In summer, ships approaching the sound are often blocked by various amounts of first-year ice, fast ice (connected to the shoreline), and hard multi-year ice. Subsequently, icebreakers are required ...
Parts of icy Antarctica are turning green with plant life as the region is gripped by extreme heat events, new research shows, sparking concerns about the changing landscape on this vast continent.
