I love that old Beatles song. “I’d like to be/Under the sea/In an octopus’s garden in the shade.”
So the polar icecaps are melting and the sea level is rising. It’s already risen about 20-40 centimeters, depending on where you are on Earth. And there are a lot of predictions about how much more ice is going to melt, and when.
Some folks made a chart about it in January of 2010 with the funny title When Sea Levels Attack!
It shows how many years it will take for various big cities around the world to become completely submerged. It’s spooky stuff, that’s for sure. The chart shows that if everything goes as predicted, in 1,000 years almost all the world’s major coastal cities will be underwater. There are these little tiny world maps on there too. There’s one that depicts what a world map will look like 8,000 years from now. The data sources are at the bottom of the graph along with a spreadsheet if you want to really be a geek about it.
Then again, the water levels might not rise that far. Though I’m sure there must be some folks already investing in real estate in sub-Saharan Africa.
Know where the title for Octopus’s Garden came from? Ringo Starr, who wrote the song, was on a boat with Peter Sellers and the ship’s captain told Ringo that octopuses travel along the seabed picking up stones and shiny objects to build gardens. (Those gardens are more like rocky dens for the octopuses to live in, but ‘garden’ sounds nicer, doesn’t it. )
I suppose if all this sea level stuff really happens, the octopuses will really go nuts with their gardening. Imagine all the stuff that’ll be submerged underwater!
The future of shipspotting may well involve stilts.
Gotta go warm up my potful of Sanka.
