Driven by climate change, global mean sea level rose 11–16 cm in the twentieth century. Even with sharp, immediate cuts to carbon emissions, it could rise another 0.5 m this century. Under higher emissions scenarios, twenty-first century rise may approach or in the extremes exceed 2 m in the case of early-onset Antarctic ice sheet instability. Translating sea-level projections into potential exposure of population is critical for coastal planning and for assessing the benefits of climate mitigation, as well as the costs of failure to act.

It is estimated that one billion people now occupy land less than 10 m above current high tide lines, including 230 M below 1 m.
