- 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%.
