Record low sea ice, the latest and not so greatest on Antarctica...
Replied to Zack Labe
@ZLabe It is truly the last look at the CryoSat-2/SMOS (CS2SMOS). In October we will continue with CryoSat-2/Sentinel-3/SMOS (CS3SMOS) in the #Arctic. CS3SMOS will also be generated for #Antarctic #seaice.

I've added a new visualization of #Antarctic sea ice thickness averaged by year, which parallels my version for the #Arctic by design. However, unlike the Arctic, there aren't any obvious long-term trends (annual mean).
Graphic will be updated yearly at https://zacklabe.com/arctic-sea-ice-figures/. GIOMAS data.

Et puis une fois terminée, je me dis finalement que c’est la meilleure que j’ai jamais faite ! 
Here's a look at the mean state of #Antarctic sea ice concentration (fraction of ice in a given area) just after the sea ice minimum (austral summer) as the freeze season begins...

That's how the volcanic Australian territory of #HeardIsland & #McDonaldIslands in the #Antarctic ended up with a 10% tariff. The #penguins got off lightly, you might say.
But #Madagascar - one of the poorest nations in the world w/GDP per capita of just over $500 - meanwhile faces a 47% tariff on the modest $733M of exports of vanilla, metals & apparel that it did with the US last year.
Last month was the 4th lowest #Antarctic sea ice extent on record for the month of March
This was 1,070,000 km² below the 1981-2010 March average. Data from NSIDC at https://nsidc.org/data/seaice_index

"Prof. Peter Wadhams, on the alarming rise of methane emissions from both the Arctic and Antarctic regions. "
"An international team on board Schmidt Ocean Institute's R/V Falkor (too) working in the Bellingshausen Sea rapidly pivoted their research plans to study an area that was, until last month, covered by ice. On January 13, 2025, an iceberg the size of Chicago, named A-84, broke away from the George VI Ice Shelf, one of the massive floating glaciers attached to the Antarctic Peninsula ice sheet".

"The influx of cold meltwater could slow the Antarctic Circumpolar Current by up to 20% by 2050.
Such a slowdown could allow more warm water to reach the #Antarctic Ice Sheet, thereby exacerbating the melting that's already been observed. In addition to contributing to sea level rise, this could add even more meltwater to the Southern Ocean and weaken the #AntarcticCircumpolarCurrent further."

40 years ago today, during my first #Antarctic and Southern Ocean research cruise, two colleagues and I began our second day on South Georgia while RRS Discovery III was moored at King Edward Point. We had camped overnight in West Cumberland Bay next to the Lyell Glacier. On this day we planned to cross the glacier and get as high as we could on the ridge on the opposite side in the time available.
We had started to try and cross the glacier the previous evening, but soon found that our rate of progress on the deeply crevassed, debris covered surface meant we would not have reached the other side before nightfall.

40 years ago today on my first #Antarctic and Southern Ocean research cruise I arrived at South Georgia for the first time. RRS Discovery III tied up at the jetty at King Edward Point, a short distance from the abandoned Grytviken whaling station. I had previously visited the Alps and spent summers working as a field assistant in Iceland and Alaska, but the mountain scenery of South Georgia was the most impressive I had seen - ice-capped mountains of alpine scale rising directly from the sea.
