Have you ever wondered what the world might look like as ocean levels rise? The map on this mug changes with temperature to show ocean levels rising. When you pour in hot liquid, the mug shows what will happen when the polar ice caps melt before your very eyes, coastlines shrink and ocean levels rise, Florida dissolves and Central America all but vanishes! Okay, it’s not completely accurate, but it’s a great conversation starter!
