This story is very tentative at this point, but I did want to point out to Climaticide Chronicles readers that Spanish researchers are reporting the breakup of 16,000 km2 of the Wilkins Ice Shelf. That would be most of the shelf.
Ina much anticipated event [in Spanish] a some 14,000 square kilometers–a surface area equal to the Basque Country (can’t we have a universal standard of comparison instead of each nation using some region that’s only meaningful to it’s citizens?), of the Wilkins Ice Sheet has disintegrated and broken up into smaller pieces, some of them glaciers 200 meters high.
The enormous icebergs into which the ice shelf has broken have begun, to flow out into the Antarctic Ocean, according to the researchers from Council for Advanced Research (Consejo Superior de Investigaciones Científicas– CSIC) whose oceanographic research vessel Hespérides finds itself in the area.
I will update as more information comes in.
