#Antarctic sea ice is nearing its annual maximum extent (austral winter). This year will not be setting any new records, though there are plenty of regional extremes as shown in August's anomaly pattern.

In August 2026, the #SeaIce global extent was 7.2% below 1991-2020 mean. Since the beginning of records (1978):
- #Arctic, 12th lowest monthly mean, with 9.1% less extent than normal (-617,526km²)
- #Antarctic, 4th lowest monthly mean, with 6.5% less exent than normal (1,178,424km²) -

Less #UVlight may mean less carbon storage in Antarctic tundraThe #Antarctic ozone layer is recovering, a major environmental success following the #MontrealProtocol. As the #ozone layer heals, less #ultraviolet radiation reaches the Antarctic surface—a change usually viewed as beneficial for living organisms.
But a new field study suggests that the ecological story may be more complicated. -

'Poised to disintegrate': Antarctica's '#DoomsdayGlacier' is set to lose its #IceShelf this year
#WestAntarctica's "Doomsday Glacier" is on the brink of losing its ice shelf, further compromising the already melting ice mass and threatening to unleash devastating sea-level rises.
By Patrick Pester
"A vital ice shelf is about to break away from Antarctica's "Doomsday Glacier," further destabilizing one of the world's largest and most vulnerable glaciers.
The #ThwaitesGlacier is nicknamed the "Doomsday Glacier" because its collapse would send so much ice into the Southern Ocean that #GlobalSeaLevels would rise by 2.1 feet (65 centimeters or 26 inches), flooding coastal communities worldwide. This collapse could take centuries, but there is an imminent threat to Thwaites' eastern ice shelf, which will likely accelerate the glacier's demise.
"Researchers say that satellite images reveal that the Thwaites eastern ice shelf is about to detach from the glacier, New Scientist reported last week. While the glacier sits on land, the ice shelf is a floating body of ice that is attached to the glacier's mouth. Researchers still have a lot to learn about the glacier, but this shelf acts as a buttress, restraining the flow of ice from the glacier into the sea."
[...]
"Thwaites Glacier's slow collapse is part of a wider concern among scientists for the future of the West #Antarctic ice sheet. Thwaites is a key pillar of the ice sheet, protecting other ice from slipping into the ocean. If the whole ice sheet were to go, sea levels would rise by 10.8 feet (3.3 m), according to the British Antarctic Survey. The collapse of ice sheets like this one are considered tipping points, or 'points of no return,' in the fight against climate change — meaning that once they are crossed, they bring about permanent changes that cannot be reversed for many thousands of years."

In the interests of my resolution to not spread bad news, here's something positive - looks like the #Antarctic #OzoneHole is getting smaller.
My ace colleagues @dmidk have a webpage they update regularly on this stuff: http://psc.dmi.dk/antarctica/ -
The annual #ozonehole over the #Antarctic is developing again. If you want to keep track, visit our website for all the latest charts and details: https://atmosphere.copernicus.eu/monitoring-ozone-layer
There you will also find the daily updated 3D rendering of the ozone hole evolution in 2024.

Warm water melts ‘#DoomsdayGlacier’ half a mile every year, finds study
#Thwaites is said to be the most unstable place in the #Antarctic and contains the equivalent of 60 centimeters of #sealevelrise
Warm, high-pressure #seawater causing significant melting under Thwaites #Glacier in #Antarctica. "There are places where the water is almost at the pressure of the overlying ice, so just a little more pressure is needed to push up the ice," said lead author Eric Rignot, PhD
