gallery of 9 satellite images from 3 January 2025 to 1 March 2026 showing A23a iceberg becoming smaller and smaller as smaller icebergs break away, and melt ponds appear on the surface.
Weβve tracked A23a iceberg for a while now, but this is our last story about it!
Once the worldβs biggest (2x the size of Greater London), it drifted north up to 47ΒΊN where warmer waters and seas broke it into smaller bergs, ending up as the worldβs largest pool as melt ponds formed on its surface.
A special FT magazine issue all about maps is out today, w great pieces by @okr.bsky.social and @theboysmithy.ft.com, plus maps by me on how glacial melt is redrawing Alpine borders, the battle to redraw America and more

This is fantastic.
Engaging people with data through game play. Also has that very Gapminder-ish quality of challenging assumption.
Love it!
Woop! Finistère gave it away with just one!

Map of Antarctica's elevation beneath the ice. Blue areas indicate land below sea level, and brown areas indicate land above sea level. Large regions, especially in West Antarctica, lie below sea level. The new map reveals with more detail what landscape hides beneath the ice, with some corresponding photographs of similar landscapes in other parts of the world today, such as Alpine mountains, plateaus dissected by deep glacier-carved valleys, and flat plains.
Side-by-side maps comparing an older and a newer map of a zoomed area in East Antarcticaβs elevation beneath the ice. Both maps use blue to show areas below sea level and brown to show areas above sea level. The newer map shows much finer detail, clearly revealing features such as the Golicyna Subglacial Highlands that are more difficult to distinguish on the older map.
Scientists have just unveiled the most detailed data yet of the terrain hidden under Antarcticaβs ice. We mapped it and compared it to the previously best available data for our story with @markpoynting.bsky.social

Two part graphic showing the daily contribution of solar in Great Britainβs electricity. The top half is a single tile chart arranged in 30-minute blocks from midnight on left to 23:59 on right with each row representing one day and ordered top-to-bottom from 1 January to 31 December 2025. Blocks are shaded by strength of generation share. In 2025, more than a dozen blocks are dark orange to show share above 40 percent. Contribution in summer days is longer and generally stronger than in winter. The second part of the graphic repeats the format as a small multiple with one fart for each year from 2013 to 2024. Each year increases in strength over that period but 2025 is the greatest contributor overall.
New record year for renewable electricity in Britain - thanks especially to strong solar output.

Satellite image of north west Gaza shows position of Yellow line and 6 yellow blocks about 500m to the south, showing misalignment.
The Israeli military is placing large yellow blocks to delineate the newly established Yellow Line in Gaza - issue is, itβs off by over 500 meters in some areas, shrinking the Palestinian safe area.
