‘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 ...
Ongoing: COVID-19 pandemic in Antarctica. February 15: A joint study by the British Antarctic Survey and the US Antarctic programme finds that glaciers on the icy continent may be more sensitive to changes in sea temperature than previously thought. Researchers used sensors and an underwater robot beneath the Thwaites glacier to study melting. [1]
Increased Antarctic melting could also potentially alter global oceanic circulations, Mikolajczyk told CNN. ... according to a 2023 study published in Geophysical Research Letters. Climate change ...
In 2023, over 90% of ocean waters experienced heat wave conditions at least once. Glaciers monitored since 1950 lost the most ice on record. Antarctic sea ice retreated to its lowest level ever.
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). [22]
Subsequent satellite observations revealed that the West Antarctic ice loss increased from 53 ± 29 gigatonnes per year in 1992 to 159 ± 26 gigatonnes per year in 2017, resulting in 7.6 ± 3.9 mm (19 ⁄ 64 ± 5 ⁄ 32 in) of Antarctica sea level rise. [6] By 2023, ~150 gigatonnes per year became the average annual rate of mass loss since 2002 ...
On the cusp of the COP28 climate talks, U.N. Secretary-General Antonio Guterres visited frozen but rapidly melting Antarctica and said Thursday that intense action must be taken at the conference ...
Climate change in Antarctica, 2023–2024 El Niño event The 2024 Antarctica heat wave refers to a prolonged and significant mid- winter increase in Antarctic temperatures compared to prior winters, causing several regions of Antarctica to reach temperatures 10 °C (18.0 °F) above normal in July 2024, up to a 28 °C (50.4 °F) increase above ...
