Yep he is that Houston guy that keeps claiming that the South is very warm in the winter and never sees any frost and freezes.
It is. In fact, I'm about to start another thread on that topic right now.

That will only hold true if the dynamics that create the DSW monsoon are related to geography only, with no latitudinal factors involved.

In the sense that year-round temps are warmer, yes, Texas would become hotter. But, in terms of actual temp magnitude, Texas would actually cool down; by shifting it 10 degrees south, you shift it away from being centered at the horse latitudes, meaning that the subtropical high pressure influence would disappear, minimizing/eliminating chance for severe heatwaves over 110.
With the current continent configuration, only the Texas coast, as well as inland areas to the far southeast in the state, escape such high heat waves. The high elevations in far West Texas also escape the heat.

Yes, Texas would indeed get cooler with such a shift south, it won't have the influence of arid high-pressure during summer, which currently dominates much of the inland areas of the state.
Without shifting the continents, ways to block the high-pressure would be by cloud-seeding, air-piercing lasers, or by building high enough walls to restrict the high pressure.

Actually, Dallas would start to fall within the tropical rain belt that allows Tampico to be wet.
fair enough. But.... Do you think a wild-type southern magnolia is going to survive single digit fs?
i don't know, but see 3rd point for why for decades later there's still vegetation.
i know how they work; i am just saying that, looking at the cold tolerance of the southern us vegetation, it seems that many would have been killed, if not severely damaged, if those record lows really were all that severe.
but now you're talking about a different measure of cold tolerance and not the usda hardiness zones. I don't know of a measure for absolute cold temp hardiness not based on any sort of average.
They will survive not only single digits but subzero.
No, an actual wild-type southern magnolia, not a cultivar you buy at the local garden shop.

i live in Mobile, I remember the sub-zero days. just a couple years ago. but its not normal weather by any means, it usually an arctic blast that made it self down from Canada in a front. the winter temp here is usually about 42 degrees

January 24, 2003 marks only 1 of 2 times that I have dropped to 15 F during the 21st century. The other was on January 7, 2014.
Fair enough. But.... do you think a wild-type southern magnolia is going to survive single digit Fs?
Yes, and even lower, but with at least some damage. A regular southern mag (from NC) has been growing in Brooklyn (zone 7) since the 1800's, it's a landmark.
No, but those temps are below the hardiness levels for those southern plants ... meaning ... that even just a minute of experience of those temps is going to do severe damage, if not outright slaughter them.
There should be at least one hulking husk/large dead stumps of live oaks killed during these freezes, if the records of Mobile were as cold as they really are.
But it is all a matter of degree, though.
No, naturally, the wild-type southern magnolia can only take cold down to USDA zone 7 at most. Since then, genetic splicing/cultivation has bred cultivars that can take temps of USDA zone 6 levels.
A minute is not gonna do anything, like, not at all. Granted 0 to -10 is pretty cold, it ain't liquid nitrogen, either. If it was an extended period of below zero, you may have a case, but a random night?
No, an actual wild-type southern magnolia, not a cultivar you buy at the local garden shop.
Highly unusual indeed.
Yes an actual wild type magnolia. They naturalized in central nc. I don't need cold hardy cultivars. Real southern magnolias will survive sub zero. Cold hardy cultivars are just southern magnolias that were a bit hardier and we're bred. Come to nc. You will see southern magnolias of all sizes everywhere. Southern magnolias are not sensitive.
But, if you look at the vegetation of the landscapes around these areas, you will find lots of southern pine, live oaks, spanish moss, etc; the hardiest of all of this southern vegetation can only handle down to USDA zone 7 (single digit Fs) at most, with many species having hardiness zones of zone 8. On top of that, such vegetation specimen in those two cities are quite large, signaling advanced age, which, in turn, signals that they have been around for centuries, at least.
Thus, I feel that if these two cities really did reach subzero temps (and if the coastal US South really did drop to single digit Fs), then the entire ecosystems surrounding the region landscapes would have been utterly annihilated and destroyed; there would be no southern pine, live oak, magnolia, etc specimen in the Coastal South that was over century old, or so, if the records are true.
I have a feeling that the record lows in the US South aren't quite valid, and may actually be quite warmer (no lower than teens, probably).
Remember, the subzero temperatures probably lasted an hour or two. If they were accompanied by a stiff wind the temperature itself may have had little effect.
In New York City it last went below zero this year, on February 14, and before that in January 1994. On those days the high was around 12 to 14. There is no way the southern readings held that low for a full day.
