Indices describe ocean conditions. Their signs do not indicate benefit or harm, and do not establish the cause of an event.

What these projections support, and what they do not

Baseline risk-change interpretation: the direction, rough pace and relative scale of change between countries and between scenarios.

Not adaptation decision-making. These are country-level means on coarse global model grids, with no downscaling and no bias correction. They must not be used for siting, engineering design thresholds, local hazard assessment, or adaptation investment appraisal.

Of 237 published jurisdiction(s), 147 draw on fewer than four effective grid cells in the coarsest contributing model. Each affected product says so in its own method and coverage panel.

Downscaling is planned and not yet part of this platform. Until it lands, a decision that turns on conditions at a particular place needs a regional or statistically downscaled product, not these values.
