We’ve all been told that global warming will raise ocean water levels dramatically along coastal areas everywhere because of the melting of the polar ice caps. Right? That’s what I was told, and for many years, I had no reason to disbelieve it. But then I had this thought: When the ice melts in my glass of Diet Coke, the level of the Coke doesn’t rise. Even if the drink is 80% ice to begin with. So how will melting polar ice caps raise the water level of the ocean? I looked into it. Turns out the term “polar ice cap” refers to the ice that sits on top of land, not in the water. DOH!
