The ocean is rising and will soon destroy island nations and various coastal cities. If you ever like strategy game, it would be ideal and futuristic to write or create scenarios of what could happen. Does the US take in refugees? Do we build levees to preserve the island nations? What would happen if we choose only a few islands to save, and let nature do what she will to the rest? Is the political ramification high or extremely low, especially since those island nations are not rich or measurably productive? They, in being uprooted, could be violent, petty, drug-addicted, or gang-trapped and lost mendicants.

Rather than being denialist, recognize that there is a trend, whatever the cause, and solve it.
