OK, I’ve always had trouble with this idea. As far as I’ve ever known, when you drop ice in a glass of water, the ice already displaces an amount of water equal to the amount of water in the ice. So as it melts, it won’t cause the water to suddenly overfull the glass. So what’s different about the polar ice that makes it so that it will raise the sea level if it’s already floating in the sea to begin with?

The Arctic polar ice IS floating, but that’s not the problem. The problem is all the ice covering land in Greenland and Antarctica, and all the other glacial melt around the world on land that will make it to the sea.
