Duvat et al.  employed an integrated systems approach to analyse future risk to habitability in atoll islands, taking into account changes in various ocean and atmospheric climate drivers and a moderate adaptation scenario . They found that, compared to present-day risk, additional risk to habitability in Male', Maldives, and Fongafale, Tuvalu, is minimal under a low emissions scenario  at 2050, although it may become moderate for Male and high for Fongafale by 2090. Under a worse-case emissions scenario , future risk to habitability in these two urban islands may increase slightly in 2050, but may increase to moderate-to-high  and high-to-very high  by 2090.
