A23A

A23A is the iceberg profiled in You’ve come a long way, Bibi: Israel’s crucial election. Anne Rowe describes it as once the world’s largest iceberg, roughly a trillion tons and about the size of two Greater Londons, calved from the Filchner Ice Shelf in 1986 and long stuck at the bottom of the Weddell Sea before drifting toward South Georgia.

The source frames A23A’s breakup in two registers. Ecologically, its fragments could threaten ships, fishing, and feeding grounds for fur seals and penguins, but could also release nutrients into the Southern Ocean. Symbolically, it becomes Iceberg Climate Symbolism: a natural ice life cycle that also carries anxiety about warming seas and the long-term fate of Antarctic ice.
