Mel Gibson starred in a movie called “Water World.” It was about the world after the glaciers on Greenland and Antarctica had melted, flooding the cities and most of the land. In the movie the surface was more than a thousand feet high. The actual depth would be about 275 feet higher than today.

Before they melt a century or two off in the future some possible events could happen making that far off eventuality come very soon, perhaps a year or two. Greenland has more ice than Antarctica’s shelves. What many people know is Greenland has several volcanoes but did they know two are under the glaciers producing a little melting Image if they started spewing lava under the ice causing them to melt while sliding off the island. All that additional water would raise the Atlantic Oceans level a “Quick” 150 feet. Coastal cities would have little time to prepare to save the buildings, all they could do is evacuate.

Antarctica has earthquakes and volcanoes too. If one or two of the shelves broke loose and slid into the ocean, the seas would rise even more and faster in the Southern Hemisphere, Coastal cities and islands would again be drowned. The rise from Greenland’s glaciers would float the shelves off the rocks holding them in place.

Either of these events would lessen when the waters spread around the world’s oceans. Even then the coastal and many inland cities would still be permanently underwater. Florida, Louisiana and much of twenty states would be under water.

These geological events could happen today, tomorrow, or never but those glaciers in both places are already melting faster every year and raising the sea levels each year. Some cities are thinking, some are planning, and some are building to postpone the flooding. Others are doing nothing.
