The loss of West Antarctica ice would take at least 500 years and possibly as long as 13,000 years. [107] [108] 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.

Original Medicare's premiums and deductibles went up in 2025. The Part A annual deductible increased from $1,632 to $1,676, and the Part B annual deductible rose from $240 to $257.
A map of West Antarctica. The total volume of the entire Antarctic ice sheet is estimated at 26.92 million km 3 (6.46 million cu mi), [2] while the WAIS contains about 2.1 million km 3 (530,000 cu mi) in ice that is above the sea level, and ~1 million km 3 (240,000 cu mi) in ice that is below it.

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 ...
How Much Will Medicare Premiums Be in 2024? This year, the monthly premium for Medicare Part B will go up to $174.70, an increase of $9.80 from the Medicare Part B premium in 2023.
Antarctica’s vast expanse of sea ice regulates Earth’s temperature, as the white surface reflects the Sun’s heat back into the atmosphere. Record low sea-ice levels around Antarctica ...
From 1992 to 1996, the two ice sheets – which hold 99% of the world’s freshwater ice – were shrinking by 116 billion tons (105 billion metric tons) a year, two-thirds of it from Antarctica.
A satellite composite image of Antarctica. Earth's south polar land mass, Antarctica, is covered by the Antarctic ice sheet.It covers an area of about 14.6 million km 2 and contains between 25 and 30 million km 3 of ice.
