Global Warming on turkey day

as i was sitting down to a luscious turkey dinner today in the air conditioning it got me to wondering........i had just talked to my brother in chicago and they were expecting temps in the single digits tonite whilst i sat in my flipflops and shorts enjoying temps around 80 degrees and a tanning index of 7.
i live in florida and dont get me wrong cause i'm not complainin but what gives? i mean its thanksgiving for cryin out loud. i cant recall the warm weather lasting this long into the year. and then there is the tropical storm factor too. most ever, although the last 2 or 3 didnt amount to much.
also just 2 days prior we had temps in the 40's. i posted this so maybe i could get a feel for the weather phenomena from someone as i dont follow the global warming thing as close as i probably should. i mean i know things aint right but this is just not right.
