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 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 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 ...
This graph shows how short-term variations occur in the measured temperature. The graph also shows a long-term trend of global warming. [64] The U.S. National Academy of Sciences, both in its 2002 report to President George W. Bush, and in later publications, has strongly endorsed evidence of an average global temperature increase in the 20th ...
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.
The William Glacier in Antarctica partially collapsed in the same week as Antarctica's hottest recorded day at 65 degrees Fahrenheit.
With an average temperature of −55.2 °C (−67.4 °F), Vostok, Antarctica is the coldest place in the world, and has also recorded the lowest temperature, −89.2 °C (−128.6 °F). [3] The following chart indicates the average and record temperatures in this research station through a year:
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 ...
