They say the sea is raising because the ice is melting but you fill a jug up with ice and top up with water and put on a tray it wont overflow as water expands when frozen and surnks when melts as i think 70% of the ice is under water but you fill up a jug with water and put a rock in it it will overflow water displacement so all the ships and boats in the sea would be more likely to make the sea rise then ice and all the things they are building in the sea
