“Glaciers and ice cover are about 15,000,000 square kilometers”
Covering, what, exactly? Land or water?
Glaciers melting over water would NOT contribute to rising seas but actually to the lowering of the seas by 10% of the glacier size.
Good point. I'm by no means a glacier expert, but simply did a little research and some math to see if the 10 foot claim was reasonable, which it isn't. There's a link to source in the original post. I assumed that this was ice over land, but that's a good point that any ice melting over water would actually lower sea levels.
