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.

First #detection of #influenza A virus subtypes #H1N1 and #H3N8 in the #Antarctic region: King George Island, 2023

Source: Vopr Virusol., AbstractRelevance. Influenza A virus is characterized by a segmented single-stranded RNA genome. Such organization of the virus genome determines the possibility of reassortment, which can lead to the emergence of new virus variants. The main natural reservoir of most influenza A virus subtypes are wild waterfowl. Seasonal migrations…

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."

Status of the #January #seaice in the #Antarctic:

- Sea-ice extent was clearly *record-low* for January this year.
- Large negative sea-ice anomalies are seen in #Bellinghausen, #Amundsen/#Ross, and even an open-water region in the eastern #Weddell Sea
