#antarctic — Public Fediverse posts

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 tundra

The #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.

💁🏻‍♀️ TIL: 🧵🌐 The hairy ball #theorem says you can’t comb a #sphere smooth without a cowlick somewhere.

The same rule explains why #Earth always has a #cyclone spinning, why #fusion reactors use #doughnut shapes, and why omnidirectional antennas can’t exist. #Wind patterns over the #Arctic and #Antarctic circles illustrate the proof.

Melting #Antarctic ice sheets may be causing larger volcanic eruptions

During #deglaciation, melting of kilometers-thick #IceSheets reduces the mass weighing down the land, which leads to #uplift. This alters the pressure inside #magma chambers lying below the Earth's surface, causing #volcanic eruptions.

This instrument is just one of many parts of the first-of-its-kind #OceanObservatory in the #SouthernOcean, launched in January in partnership with #UVIC, #SpanishNationalResearchCouncil & #OceanNetworksCanada.

The #observatory monitors temperature, water depth, oxygen & chlorophyll levels in the #ocean water. Paired to a #satellite, the observatory transmits #data every 30 mins to #researchers.

"Changes in #ocean circulation can affect uptake of both #heat and #CarbonDioxide over many thousands of years," Caldeira continued. "The #decisions we make about #energy systems and #deforestation over the next years will affect #Earth 's #climate for many millennia in ways that are now poorly understood."

Watching #FrozenPlanet2 last night, saw the segment about #stromatolite life in #Antarctic lake. Amazing! https://www.youtube.com/watch?v=QzEVeFBXfNg

Took a quick look at the #Antarctic #SeaIce data from #OSISAF colleagues. It's not looking great ..

After some years of rising extent the last few years have shown a starting decline down to this year's record minimum...

Staying with #Antarctic #IceShelves - I also found I had revisited this super cool paper by the awesome #DrGilbz (#EllaGilbert) and Christoph Kittel on the likely futures of the peninsula shelves under different warming scenarios..
tl;dr - limit the warming to save the shelves..
