One point. I do believe that the majority of the rising sea levels was due to the seas heating up and the water expanding. Granted, this expansion would be tiny at a small volume of water, but when you take into account that the sea is very fvcking big, a tiny change in sea temperatures would result in a large rise of sea levels. One point though. If global warming ahs been happening for a long time now, its just that its only recently been brought up, this means sea levels should have been rising for a while? How come the places that are below sea level, aren't already below the sea?
