  Yes, while the radiation puts more energy in than the convective etc. cooling removes. So near 0 this is guaranteed, since the temperature difference from ice to ambient is almost 0 while radiation keeps pumping in something like 0.5 W. But who eats ice at freezing temperatures… And outside?

    I have eaten ice cream outside when temperatures were sub-zero Fahrenheit. It’s not something I do regularly but it’s happened and will probably happen again.

    If I want ice cream, then I want ice cream. No other considerations matter.

      Alright then. But at 0 °F it is not going to melt without your intervention, no matter how sunny it is.

        Absolutely, I don’t disagree with that.

        I was just sharing my anecdote as a counterpoint to your minor rhetorical point at the end, because at least to me, it’s funny since eating ice cream outside at -10 degrees is a ridiculous thing to do.

        Though, I will note that while ice cream won’t melt at those temperatures, at atmospheric pressure it will still sublimate. So, in that way you could still lose your ice cream without intervention, it would just take a while.
