An excellent analysis by the chemist, but unless I missed it reading it, I saw an assumption/implication that the only temperature of water in a frozen state is 32 Fahrenheit/0 Celsius. That's just not the case. Ice can be much colder in temperature than the freezing temperature of water. Water needs pressure involved to reach temperatures above its boiling point, but it doesn't need anything other than the presence of cold to get below its freezing point. I can safely say that the majority of frozen water on this planet is not exposed to the atmosphere or the sun, is frozen at a temperature below the freezing point (well below for much of a year), and would take longer to melt than anyone is projecting, even with the nonsensical/hysterical predictions of 5 degrees increase in average temperature. The window for such a calamity would be 10's of 1000's of years wide, not 2 or 20 or 50.
