Many Canadians have experienced being on a flight somewhere warm and tropical and returning home to cold and miserable weather. Leaving Phoenix or Fort Lauderdale, it may have been 30 degrees. But as the plane begins to land at the Canadian destination, the pilot may announce, “The current temperature is 1 degree.”You may ask “Did he say 1 degree? Or -1 degree?” At that point, the difference between water freezing or not will be meaningless. It’s going to feel much colder regardless of the negative sign in front of the digit.
