Sure, Bengladesh is a low-lying country. We've seen what water does in New Orleans. There are entire low-lying COUNTRIES in the Indian and Pacific Oceans. High water would take a toll on atolls, of course. Amsterdam and much of northern Netherlands are famously threatened by high seas. London, England, already has barriers to block higher tides from swamping the city's historic riverside. But you could argue that Venice, Italy, has as much to lose to the sea as any place on earth. St. Mark's Square already floods regularly. There is very little "dry" land in Venice that is truly well above sea level.
So Venice is taking direct action. They want alternative sources for electricity to run their lights, and their sump pumps.

Venice hopes to have its algae-driven bioreactor online in 2011. The coal industry would love to see algae succeed as a power source, it could eat up much of the CO2 NOW emitted by coal-burning popwer plants and industries.
