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 ...
‘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 ...
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.
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.
This heat wave lead to some regions of Antarctica facing temperatures that were up to 22 °C (39.6 °F) higher than normal and caused significantly reduced levels of sea ice, leading to extensive research on the event by a major global research project consisting of 54 members, who described the complexity of the heat wave's cause as "head ...
As the sea ice recedes epontic algae dominate the first phase of the bloom, and a strong bloom dominate by diatoms follows the ice melt south. [13] Another phytoplankton bloom occurs more to the north near the Antarctic Convergence, here nutrients are present from thermohaline circulation. Phytoplankton blooms are dominated by diatoms and ...
(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.
