When I was a kid, I was taught that Sweden rises 1cm each year.
I was also taught that H2O takes up more space in ice form than in liquid form.
So, whenever I've heard people claiming the ice cap will melt and flood the earth, it's never made any sense.
Also, having grown up with 3+ feet of snow all over the place, that melts each year, sure, some creeks will flood, but no where close to the amount of snow.
