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.
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.
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 ...
Global average temperature, atmospheric CO 2, and sunspot activity since 1850. Thick lines for temperature and sunspots represent a 25 year moving average smoothing of the raw data.

The William Glacier in Antarctica partially collapsed in the same week as Antarctica's hottest recorded day at 65ºF. It lasted for several minutes and stretched half a mile.
The surface temperature record extended back to 1880. (UAH 2003; data set tltglhmam version 5.2 with 2009 updates) and Schabel et al. (RSS 2002; data set tlt_land_and_ocean with 2009 updates). These two satellite records reflect two different ways of interpreting the same set of microwave sounder measurements and are not independent records.
