> I would not be surprised to see Mangroves at that latitude. You should be! Per TFA: "60 miles north of its previously recorded range—by far the northernmost mangrove in the U.S" IMHO each observation of a new out-of-range specimen will be unsurprising without remembering the poetic lessons of infinitesimals, ex. Ship of Theseus, if not the prosaics of infinitesimals themselves. > It's probably more surprising that these areas aren't already subtropical. Given my surprise at this comment, I think I may be missing the significance in the switch from unsurprising there's a new record for US mangrove latitude to surprising it wasn't already subtropical. Is a mangrove a sufficient condition for being subtropical? Is it a necessary condition? My understanding is Florida is firmly subtropical on all the tentpoles: hot summers, mild winters, and rarity of frosts (famously, enabling its orange farming). > Climate change seems to reduce whatever factor caused the cooling there. Occam's Razor would say this adds an unneeded factor of a previously-unknown-to-humanity outlier cooled state, to further an irrational argument that it isn't surprising.
