‘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 ...
Antarctic sea ice extent peaked this year on Sept. 10, when it covered 16.96 million square kilometers (6.55 million square miles), the lowest winter maximum since satellite records began in 1979 ...
‘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 ...
After sea ice melts, more energy is absorbed by the ocean, so it warms up. This ice-albedo feedback is a self-reinforcing feedback of climate change. [73] Large-scale measurements of sea ice have only been possible since satellites came into use. [74] Sea ice in the Arctic has declined in recent decades in area and volume due to climate change.
Vostok Research Station is around 1,301 kilometres (808 mi) from the Geographic South Pole, at the middle of the East Antarctic Ice Sheet.. Vostok is located near the southern pole of inaccessibility and the south geomagnetic pole, making it one of the optimal places to observe changes in the Earth's magnetosphere.
Halley Research Station is a research facility in Antarctica on the Brunt Ice Shelf operated by the British Antarctic Survey (BAS). The base was established in 1956 to study the Earth's atmosphere . Measurements from Halley led to the discovery of the ozone hole in 1985. [ 3 ]
In the IPCC’s 2021 report, scientists estimated that sea level will rise about 0.9 to 3.3 feet (0.28 to 1.01 meters) by 2100, but also said those numbers didn’t factor in uncertainties around ...
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.
