For island nations that live inches above the tide, every millimetre of rising sea erodes the beaches that tourists fly across the world to see — and turns storms into national debt.
The Driver
Sea level relative to the 1993 baseline at every one of the eight islands. The steps are coarse — the source publishes values rounded to ten centimetres — but the direction is unmistakable.
The Exposure
Each bubble is a nation: how much coastline it has to lose (x), how many tourists its shores attract (y), and how large its recorded disaster losses have been (bubble size). Drag the year to watch exposure grow.
The Cost
