Alex, I have a theory about these things. And we have been having our ups and downs here - freezing one day and hot the next. Snow out of season and that sort of thing. My theory involves Scotch Whisky and ice cubes. Get yourself a glass and pour some of your favorite single malt into it. Now drop in an ice cube. Do you doubt that the world of that little ice cube is getting warmer as you sip? But what is happening to the Scotch? Amazing. The profundity of this lesson becomes more clear with each repetition of the experiment. I encourage it - really.
