Just watched a documentary that blames much of it on the incredible lack of "ICE" in the Arctic, which is below any known times (during human existence) right now...
Weather people don't know jack IMO
But we who live here know 'something' is up.
All I know is that my first two winters as a resident in Florida (greater Tampa area) I saw ice fall from the sky and overnight temps with a 2 handle and day highs that didn't get into the 60's. It was serious enough for me to consider moving even FURTHER SOUTH, but Miami had frost those winters also.
This year, haven't seen frost yet and SUN, SUN, SUN...now, that's NORMAL!
