Mont Choisy is a vast, breathtakingly lovely
lagoon of warm,
calm waters that are safe to swim and snorkel in, and
shallow enough that fishing boats are not often seen invading the fringes of the outer bay.
The computer simulations of changing conditions in vulnerable regions later this century − in a blazing landscape fed by a river delta flowing through steamy marshland, and enfolding a
calm, relatively
shallow 1,000 km
lagoon of evaporating seawater − have delivered a stark conclusion.
