6am in central Florida, 08.11.19, 37 degrees. Places just to the north of where I am (Lakeland) have reported 32 & below!

This is January weather for us, and yes, this can be attributed to global warming.
There have been several recorded "Mini Ice Ages" in the 1100's, 1400's, 1500's & 1800's all caused by gigantic pyroclastic volcano eruptions that darkened the skies globally. They lasted roughly 5-15 years each time. In the 17th century, snow fell in the New England states in May and June and wiped out all the crops. There was quite a bit of starvation and death. The Great Potato Famine in Ireland in the mid-1800's has also been attributed to sub-normal temperatures.
Today, we can attribute our freakish weather to the industrial cities in China where the air quality makes Los Angeles' smog look like squeeky clean air! The sun's penetration in Bejing is diminished by approximately 25% due to all the air pollutants - which do travel globally. In the super industrial years from Post WWII to the mid-80's we here in America experienced roller-coaster winters due to pollution. I particularly remember winters in the 1960's where snow drifts went above the roof of our house, and one storm in 1963 where we had to dig out of the front door. Those of you living in WNY can probably recall the great blizzard of 1977, and other such storms in NYC, Boston, Philly & Washington DC.
Global warming causes weather patterns to shift drastically, partly due to glacial melting. In past centuries this was caused by natural events. Today it is caused by man made events, such as gross pollution.
BTW...I'm not smart, or scientific...I just love to watch the History Channel & the Weather Channel and have always been interested in meteorology.
Here's a link to a basic explanation of previous Mini Ice Age's in Europe.
