When the ice in my former tipple of choice, Jack Daniels & Coke, melted, did the drink level rise in the glass? A usually reliable friend told me that this glacier melting business won’t result in the sea level rising. Is it true? Can a physicist explain this please?

Guido isn’t allowed Jack Daniels & Coke after an unfortunate incident involving Janet Street-Porter. Too complicated to explain the details, but it involved Guido releasing his pent up hatred of the mad old cow and being dragged out of a Chanel party by two bouncers. She didn’t press charges and Guido no longer drinks Jack Daniels & Coke.
