Record-breaking low levels of sea ice around Antarctica in 2023 may have been influenced by climate change, scientists have said. Researchers at the the British Antarctic Survey (BAS) analysed ...
(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 ...
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.
The lowest air temperature record, the lowest reliably measured temperature on Antarctica was set on 21 July 1983, when a temperature of −89.2 °C (−128.6 °F) was observed at Vostok Station. [ 2 ] [ 5 ] For comparison, this is 10.7 °C (19.3 °F) colder than subliming dry ice (at sea level pressure).
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.
Because the East Antarctic ice sheet is over 10 times larger than the West Antarctic ice sheet and located at a higher elevation, it is less vulnerable to climate change than the WAIS. In the 20th century, EAIS had been one of the only places on Earth which displayed limited cooling instead of warming, even as the WAIS warmed by over 0.1 °C ...
‘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 ...
