Well.. Global warming, wether true or not, does mean colder and harsher winters...

Also there was something on discovery not too long ago where they said the last ice age happened alot faster than originally thought. Like a matter of months instead of years as was originally thought.

As for the freezing temps in FL. I dont see how these animals can just snap out of it and live healthy lives. Most will die. The rest will be sick. IMO
