Will global warming make Cyrtostachys renda viable in Miami?

[Blueman]

The world has a history of long-term cyclical changes in temperatures of varying duration.  These occur due to the wobble of the earth's axis over time, and when the seasons fall in relation to the distance from the sun, since our orbit isn't circular. 

The Great Warming lasted from the 10th to 15th centuries, with sustained temps far above normal, allowing crops to be grown in places they couldn't before.  What would the climate experts of today say if we were in the midst of that again now.   That was followed by The Little Ice Age which was a series of very three cold cycles which began in 1650, 1770, & 1850, with warmings in between each.  Pretty big swings, all of them natural and part of a bigger picture of cycles that can understood when looked in the context of hundreds or thousands of years.    

I personally won't plant tender anything based solely on the assumption we'll be much warmer in the near future.

Going to revive this for a couple of reasons.   
 

the first of which is that I finally have gotten ahold of a good sized one of these and it is in its way to me from south Florida.   
 

The other thing I wanted to add is that I’ve the last few years, I have come to learn there are several of these being grown here in southern Pineallas / St. Pete both in ground and in containers.    In the time I have lived here (going in 6 years) we have hit low to mid 30s very briefly a few times.    To my knowledge none of these palms suffered much and are doing ok. A little browning and that is all I heard about.  I don’t know if they ever got protection other than one who had one in a pot and brings it in when it goes under 50.   I find that a little surprising but not completely.    No idea what’s happened after this last cold snap.  
 

Granted those temps are for an hour or so around sunrise and most of those cold nights are around 40-44 before between 1 am and 4 am and dropping off just before sunrise.    So far every time it’s been very very short duration in the 30s.  The temps climb rapidly once the sun rises and almost always recovers into the upper 50s at least. This past little cold snap was the first time in my nearly 6 years here that we actually did not hit 50 during the day.   48 was all we could do.   My coldest lows here on the water were 35 and 36 respectively and it was for barely 60 minutes.
