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 ...
Since the Last Glacial Period, temperature trends have suggested that the interplay from the Antarctic High and Southern Annular Mode has played a significant role in katabatic winds over the Patriot Hills Base Camp. [3]
Antarctica lost a staggering 280% more ice mass in the 2000s and 2010s than it lost in the 1980s and 1990s, according to a 2019 study published in the Proceedings of the National Academy of Sciences.
Two temperature records were set on February 6, one in each hemisphere, one for warmth, the other for mind-numbing cold. On Feb. 6, 2020, five years ago, Antarctica set its all-time record high of ...
3 March: Scientists confirm that Ice levels have registered historic lows for a third consecutive year. [1]3 August: 2024 Antarctica heat wave: A record prolonged heat wave persists over Antarctica, with temperatures reaching 50 °F (28 °C) higher than average in some areas during the middle of winter.
The current is circumpolar due to the lack of any landmass connecting with Antarctica and this keeps warm ocean waters away from Antarctica, enabling that continent to maintain its huge ice sheet. Associated with the Circumpolar Current is the Antarctic Convergence , where the cold Antarctic waters meet the warmer waters of the subantarctic ...
For a huge chunk of the U.S., you may have thought it couldn’t get much colder during the last month, but Earth as a whole just experienced its warmest January on record, according to a new ...
