Greenland's melting ice mass is now the No. 1 driver of sea level rise, according to Paul Bierman, a scientist at the University of Vermont. If it melts completely, scientists project it could ...
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Using 50 different ...
The West Antarctic ice sheet is likely to completely melt [17] [18] [19] unless temperatures are reduced by 2 °C (3.6 °F) below 2020 levels. [20] The loss of this ice sheet would take between 2,000 and 13,000 years, [21] [22] although several centuries of high greenhouse emissions could shorten this time to 500 years. [23]
Of the continent's 162 ice shelves, 68 show significant shrinking between 1997 and 2021, while 29 grew, 62 didn’t change and three lost mass but not in a way scientists can say shows a ...
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 melting of all of the ice in West Antarctica would increase global sea-level rise to 4.3 m (14 ft 1 in). [98] Mountain ice caps that are not in contact with water are less vulnerable than the majority of the ice sheet, which is located below sea level.
With detailed weather station and satellite data dating back only about 40 years, scientists wondered whether these events meant Antarctica had reached a tipping point, or a point of accelerated ...
Since the East Antarctic ice sheet would not be at risk of complete disappearance until the very high global warming of 5–10 °C (9.0–18.0 °F) is reached, and since its total melting is expected to take a minimum of 10,000 years to disappear entirely even then, it is rarely considered in such assessments. If it does happen, the maximum ...
