The ozone hole above Antarctica is predicted to slowly disappear; by the 2060s, levels of ozone are expected to have returned to values last recorded in the 1980s. [110] The ozone depletion can cause a cooling of around 6 °C (11 °F) in the stratosphere.
At greater warming levels, this effect is likely to disappear due to increasing concentrations of water vapor over Antarctica [26] Antarctica is the coldest, driest continent on Earth, and has the highest average elevation. [1] Antarctica's dryness means the air contains little water vapor and conducts heat poorly. [26]
Now, the potential for the West Antarctic Ice Sheet to disappear after a certain temperature is exceeded is considered one of the tipping points in the climate system. Earlier research suggested it may withstand up to 3 °C (5.4 °F) before it would melt irreversibly, [8] but 1.5 °C (2.7 °F) was eventually considered a more likely threshold.
Greening on the Antarctic Peninsula increased from less than 1.1 square miles in 1986 to nearly 14.3 square miles in 2021.

After 2016, some ice sheet modeling exhibited the so-called ice cliff instability in Antarctica, which results in substantially faster disintegration and retreat than otherwise simulated. [ 26 ] [ 27 ] The differences are limited with low warming, but at higher warming levels, ice cliff instability predicts far greater sea level rise than any ...
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]
