Will Hobbs @icecoldwill.bsky.social · 11hUpdate; my guess that the sea ice would rapidly retreat has sadly proven correct. After an intense start to the spring melt, sea ice cover is about to make a record low for early October, beating 2023 000

Will Hobbs @icecoldwill.bsky.social · 30/09/2026Another year with sea ice cover well-below “normal” (whatever that means now). The start of the spring melt has been very rapid; hopefully that’s just weather but I suspect that the west Antarctic sea ice is thin and will melt quickly 121
