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 ...
The temperature on land rose by 1.59 °C while over the ocean it rose by 0.88 °C. [3] In 2020 the temperature was 1.2 °C above the pre-industrial era. [4] In September 2023 the temperature was 1.75 °C above pre-industrial level and during the entire year of 2023 is expected to be 1.4 °C above it. [5]
These measurements reflect averages over a large region and so are lower than the maximum point surface temperature. [ 6 ] 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 81°48′S 59°18′E / 81.8°S 59.3°E ...
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 loss of West Antarctica ice would take at least 500 years and possibly as long as 13,000 years. [21] [22] Once the ice sheet is lost, the isostatic rebound of the land previously covered by the ice sheet would result in an additional 1 m (3 ft 3 in) of sea-level rise over the following 1,000 years. [23]
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 IPCC Fifth Assessment Report (AR5 WG1) of 2013 examined temperature variations during the last two millennia, and cited the following reconstructions in support of its conclusion that for average annual Northern Hemisphere temperatures, "the period 1983–2012 was very likely the warmest 30-year period of the last 800 years (high confidence ...
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 ...
