In South Louisiana we consider anything below 50 to be cold and if we actually get to freezing, we change the way we live. It doesn't look like we are going to be seeing any sub freezing weather anytime soon here. In Siberia temperatures below freezing are the rule and not the exception. This is video from Siberia. The temperature is minus 41 degrees. Watch what happens when boiling water is tossed out into that extreme temperature. Incredible!
