On Dec. 21, 2024, the Antarctic sea ice extent was higher than on Dec. 21, 2016, but the Arctic sea ice extent was lower on that date in 2024 compared to 2016, according to government data.
‘Lower sea ice extent means that ocean waves will pound the coast of the giant ice sheet, further reducing ice shelves around Antarctica’ Antarctic sea ice hits new record low in 2023 Skip to ...
‘There is some concern that this may be the beginning of a long-term trend of decline for Antarctic sea ice’ Antarctic sea ice hits ‘record-smashing’ new winter low, data shows Skip to ...
These retreats would have added about 0.5 m (1 ft 8 in) and 0.9 m (2 ft 11 in) to sea level rise. [25] The East Antarctic ice sheet is far more stable than the West Antarctic ice sheet. The loss of the entire East Antarctic ice sheet would require global warming of between 5 °C (9.0 °F) and 10 °C (18 °F), and a minimum of 10,000 years.
The circa 10 metres (33 ft) of sea level rise from the combined melt of Greenland and West Antarctica would require moving many cities inland over the course of centuries, but would also accelerate sea level rise this century, with Antarctic ice sheet instability projected to expose 120 million more people to annual floods in a mid-emissions ...
(Reuters) -Sea ice that packs the ocean around Antarctica hit record low levels this winter, the U.S. National Snow and Ice Data Center (NSIDC) said on Monday, adding to scientists' fears that the ...
The Antarctic sea ice cover is highly seasonal, with very little ice in the austral summer, expanding to an area roughly equal to that of Antarctica in winter.It peaks (~18 × 10^6 km 2) during September (comparable to the surface area of Pluto), which marks the end of austral winter, and retreats to a minimum (~3 × 10^6 km 2) in February.
Record ice loss in 2023 has added up to seven extra storm days per month in some areas
