Aw, I'm still in 9a.

 I heard that many years ago it used to be a lot warmer here and they used to grow a lot of citrus commercially. Anyone know what zone Jacksonville was like 20-30 years ago?

Was it 20-30 years ago that they used to grow it? I remember reading in a book about the History of Citrus that a while back (I think even more than 100 years ago) there were many citrus groves further north in the state because there hadn't been a strong freeze in a few years. After many people planted out acres of citrus and the trees were doing well, a really strong freeze happened and killed off all the groves that were too far north. The groves were not replanted in fear of losing everything again. Since I do not have the book, what I said is just from memory and could be completely wrong. I will try google and see if I can find more concrete info about it.

Hmm, doesn't seemed to have changed much since 1990.

Yeah, I think it was about 30 years ago. My parents moved to Florida in the early 80's and my mom said that north Florida was warmer then and grew citrus commercially.

And Florida has changed with rainfall as well, I remember when I was little, like in the 90's, that it used to rain nearly every afternoon in the summer. I remember hating that because we'd have to plan swimming in the pool and going to the beach around the rain. Now it doesn't rain near enough, my retention pond has been low for 2 years now.

Here's a link to the history of significant Florida freezes from a citrus grower's point of view. The 2010 freezes are not included in this.

Zands... be nice  You know us liberals get hurt when someone talks bad about global warming!

Tell me about it, it is really really tough. So tough that Al Gore recently bought an 8 million dollar mansion (with big carbon footprint) right on the California coast. So much for his dire warnings of rising sea levels.

I've read that central Florida had fewer temperature extremes, e.g. hard freezes, back before some of the land was drained.   Apparently swampy areas retain more heat than dry ones, in the winter at least.
As far as global warming/weirding/climate change, I'm not offended by any sort of opinion about it, despite being a card-carrying liberal. (A library card counts, right?)
Maybe it's happening and man-made.  Maybe not.  Nobody actually knows. Maybe our great-grandchildren will find out one way or the other.
At any rate, I'm happy to see that the topic isn't generating any sort of flame war.
But if someone were to post that Carrie mangos are great and Dot mangos suck, I'd have to get nasty.....
