As the #Antarctic ice sheets thin under a warming climate, newly exposed mountain peaks may increase the supply of nutrients to the surrounding Southern Ocean - strengthening its natural ability to absorb carbon dioxide from the atmosphere via @oceanographicmag.bsky.social
Exposed Antarctic peaks could boost ocean’s carbon absorption - Oceanographic
Thinning ice in Antarctica may reveal nutrient-rich mountains, enhancing Southern Ocean’s role as a natural carbon sink over long timescales.

Was there any coverage of the recent record warmth in both the Arctic and Antarctic? Multiple global datasets now confirm these records, and I think it's really quite striking.

Here's some very quick plots showing NOAAGlobalTempv6 data from October too. And see my earlier posts.
