I have a serious question, so I heard some scientist on BBC radio a few years back saying that the rise in sea levels does not equate to the amount of new water made by melted ice. He went on to say that the weight of the extra water actually pushes down on the seabed effectively making space for itself to a degree, he estimated that the actual rise in sea level was only going to be something like 2 feet which he went on to say would still be catastrophic for many people. Was he right?
