Sea Level Rise

From Reuters:  U.N. Secretary-General Ban Ki-moon said earlier this month global warming, blamed mainly on burning fossil fuels, could raise sea levels by 50 cm to 2 meters (20 inches to 6 ft 6 in) this century -- higher than most experts have predicted.

But, but, but...

The projections are always low, and have to be updated every couple of years!  So the sea level rise will probably be much more than presently projected. 

My personal guess is 10 meters, maybe 20.  Check back in 91 years and we'll see who's right.
