Since icebergs float, as they melt they don't sit as deep in the water and they don't displace as much water. So as the iceberg melts, and when pieces break off, the balance is maintained and nothing changes. However at the LIDA Film Festival tonight, living legend, environmentalist and pioneering underwater explorer Jill Heinerth actually said that as icebergs melt due to global warming, sea levels rise and if this continues there will be major flooding in coastal areas everywhere as a result.
Now don't get me wrong, it's understood that icebergs are composed of less dense fresh water that displace less salt water than the added volume when melted, but the difference is minute- not enough to cause major flooding as stated- sea level rise due to melting icebergs is estimated to be less than 5/100ths of a millimeter per year.
