“Take a glass. Fill it with ice cubes. Add water until the ice reaches the rim. What happens when the ice melts? Does the glass overflow with water?”
That’s only true for ice floating in water (like the Arctic). In the antarctic the ice is sitting on land.
But it’s the same amount of water that was around at the beginning of the earth. Some was liquid, some froze and some is gas (i.e. vapor).
In the antarctic the glass of water will never melt, it will freeze forever.........Since we know the ice will never melt in that glass, the question that needs to be asked is whether or not a glass of gin with ice will freeze over and is the antarctic the perfect environment for martinis
