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.

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.

- Large negative sea-ice anomalies are seen in #Bellinghausen, #Amundsen/#Ross, and even an open-water region in the eastern #Weddell Sea
