  1. #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.

  2. 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.

  7. 💁🏻‍♀️ 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.

    Rapidly melting #Antarctic ice shelves may cause global #seaLevels to rise far faster than expected – new study
    Global sea levels may rise faster than previously expected, a new study suggests. The reason is that warming oceans appear to be melting Antarctic ice shelves from below much more rapidly than expected

  9. World-first footage shows #Antarctic #seafloor scoured by #cruiseship #anchors
    Researchers claim to have world-first footage of damage to sensitive and biodiverse Antarctic sea floor ecosystems caused by anchors and chains.
    The team behind the discovery has called for tighter regulation of Antarctic anchoring practices, particularly for the growing #tourism sector.

  10. Bon allez, une fois n’est pas coutume, j’ai posé avec ma carte marine avant de la confier à son nouveau propriétaire... 😄📜 Oui, je suis en t-shirt, dehors, en Antarctique ! ❄️🙃 Oui, j’avais un peu froid ! Mais promis, je ne suis pas restée longtemps ! 🥶😂
