An interactive global model explores what might happen if the fictional ice-nine from Kurt Vonnegut’s Cat’s Cradle entered the ocean.

For
Readers exploring climate physics and Cat’s Cradle
Worth noticing
The project reports an energy budget that closes to 0.03%, alongside convergence tests and 25 scenarios that vary one assumption at a time.

Field notes

The two model branches turn a missing detail in the novel—the density of ice-nine relative to water—into the central variable. The runs begin from a single Caribbean seed in October on a 0.5° grid, and the page reports 25 twelve-year scenarios, each changing one assumption, plus convergence tests and an energy budget that closes to 0.03%.
