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]
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 ...
In March 2022, temperatures in some parts of the continent reached up to 70 degrees above normal, the most extreme temperature departures ever recorded in this part of the planet.
English: Antarctica.An orthographic projection of NASA's Blue Marble data set (1 km resolution global satellite composite). "MODIS observations of polar sea ice were combined with observations of Antarctica made by the National Oceanic and Atmospheric Administration’s AVHRR sensor—the Advanced Very High Resolution Radiometer."
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 ...
The UN weather agency said Friday that an Argentine research base on the northern tip of Antarctica is reporting a temperature that could be a record high. A base in Antarctica recorded a ...
Antarctic surface ice layer temperature trends between 1981 and 2007, based on thermal infrared observations made by a series of NOAA satellite sensors.. Climate change caused by greenhouse gas emissions from human activities occurs everywhere on Earth, and while Antarctica is less vulnerable to it than any other continent, [1] climate change in Antarctica has been observed.
