‘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 ...
A record loss of sea ice in Antarctica is dramatically affecting the survival of emperor penguins, researchers said Thursday. Last year’s historic low levels of ice around the Antarctic ...
[74] [75] [76] According to one study, if the Paris Agreement is followed and global warming is limited to 2 °C (3.6 °F), the loss of ice in Antarctica will continue at the 2020 rate for the rest of the 21st century, but if a trajectory leading to 3 °C (5.4 °F) is followed, Antarctica ice loss will accelerate after 2060 and start adding 0.5 ...
Off the charts “crazy” heat in the North Atlantic ocean and record-smashing Antarctic sea ice lows last year are far more severe than what Earth’s supposed to get with current warming levels.
Reporting on the reduced Antarctic sea ice extent in mid 2023, researchers concluded that a "regime shift" may be taking place "in which previously important relationships no longer dominate sea ice variability". [46] The area burned by the 2023 Canadian wildfires was more than twice that of any prior year of record. [47]
Ice loss from the West Antarctic Ice Sheet (along with much smaller losses from the East Antarctic Ice Sheet adds meltwater to the Southern Ocean, at a total rate of 1100–1500 billion tons (GT) per year. [8]: 1240 This meltwater is fresh, and when it mixes with ocean water, the ocean becomes fresher (less salty) as well. [76]
November 27: The British Antarctic Survey confirms that the world's largest iceberg, A23a, is now leaving the Weddell Sea and drifting into the Southern Ocean after being in the Weddell Sea for more than 30 years. The iceberg is expected to follow the Antarctic Circumpolar Current and continue to drift away from Antarctica. [3]
A JPL analysis published in 2022 found that thinning and crumbling away of Antarctica's ice shelf had reduced its mass by some 12 trillion tons since 1997, double previous estimates.
