️ While extent will not be setting any annual minimum records this year, the average thickness of #Arctic sea ice is actually at historic lows for this time of year (in the dataset by PIOMAS). Thinner ice is younger and usually more fragile.More graphics of thickness and volume: https://zacklabe.com/arctic-sea-ice-volumethickness/

Oh look, a new ARS piece talking about this stuff!Predictably the scientists quoted will only accept the reduction in carbon emission as the only sustainable solution. (And they're right!)「The assessment shows that “no current geoengineering idea passes an objective and comprehensive test regarding its use in the coming decades,”」Yes dear sherlocks, but we do want to slow down *all* the 'engines' of the negative feedback loop, right? Even if polar krill populations will face hard times for a decade or few.Once we kickstart the runaway feedback loop and begin releasing the massive 'fossilized' arctic CO₂ and methane reserves we humans simply can't put the plug back in.https://mastodon.social/@arstechnica/115174558308289672https://arstechnica.com/science/2025/09/geoengineering-will-not-save-humankind-from-climate-change/?utm_brand=arstechnica&utm_social-type=owned&utm_source=mastodon&utm_medium=social#globalwarming #climatechange #arctic #antarctic #geoengineering

Changes in September temperatures in the #Arctic by decade. The largest warming is co-located with areas of melting sea ice, such as the along the Eurasian coast.Data from https://doi.org/10.24381/cds.f17050d7
