Interesting. The nation's main airport is Bonriki International Airport. Its runway is close to the ocean on the eastern end. But rather than a seawall - like would be needed if sea levels were rising - there is a highway/street between the runway and the ocean.
And yeah, the UN can go ...... . BTW, if the UN really believes in Global Worming, why hasn't it moved from its headquarters on the shore of the tidal East River?
