This effect also happens when big ice sheets on land melt. Their water causes the sea level to rise overall, but since their gravity no longer pulls the ocean toward them, the sea level can actually fall in the area around the sheet. On the other side of the world, it will rise by more than you’d expect. If or when Greenland melts, the flooding will be worst in Australia and New Zealand. For more on this, see How To, chapter 2, “How to Throw a Pool Party.”
