"The Great Global Warming Swindle" movie a swindle?

I like searching through classic literature looking for references to where cold sensitive crops are being grown at the time.  If the world is getting warmer, why you can't grow oranges outside without protection in Natchez, Mississippi?  In Mark Twain s 'Life on the Mississippi', published in 1883, a travel log where he documents his trip down the Mississippi, he mentions Natchez as the northernmost location where you can grow oranges outside without protection and that from that point on south he mentions seeing orange trees growing at the various towns and plantations he visited. Today you can't grow oranges outside without protection north of New Orleans.  Mark Twain had a reputation of being a very astute observer, so if said oranges were growing in Natchez, they must have been growing there at the time.

In another book 'The Escape of General Breckenridge ' documenting the escape of Confederate secretary of war General John Breckenridge and his military staff ahead of union forces at the end of the Civil War by travelling the length of Florida to Cuba, they mention collecting coconuts from abandoned homesteads on Merritt Island, a location too far north and too cold to grow coconuts today, and which today are only found north to Jupiter Inlet.  The book also mentions the methods they used to manage biting insects in the days before DEET.  The references in both of these books would indicate a warmer climate in the mid to late 1800's than we have today.

If the world is getting warmer why has the east coast citrus industry have to keep moving south.  In the late 1800's it was centered in southern Georgia to nothernmost Florida. By the early to mid 1900's it was centered in the region between Gainesville and Orlando, then after the 1970's cold snap moved south to the region between Orlando and Lake Okeechobee where it is centered today.

I can grow oranges here in France but they would not be the modern commercial kind are you sure you are not mixing the two . This I would expect Mark Twain was correct this may not indicate a change in temperature but of commecial operation .
Plus coconuts are often swept hunderds of miles from where they are grown and collected on the beach by the poor of many countries far to cold to grow there own .

For what it is worth, some scientists think there is a connection between a warmer climate and more cold snaps, which would be devastating to perennials. I know here in Denver, the trend has been warmer winters with less snow, but spring frosts are still as late as ever. This is actually very bad for perennials, which are flowering and leafing earlier and earlier, thus getting frozen more and more often in the spring. A few more rounds of this, and the Denver urban forest will die off. I would guess the same would apply to the limits of tropic plants.

A warmer world may be much more unstable.

If you think global warming means that it's just going to be warmer in any given area, I would urge you to read the literature about what global warming actually does.
