No, the palm tree is not threatened by rising seas. This is about something that will endure.
There's something reassuring, almost festive, about the presence of palm trees near the coastal beaches. Maybe they say vacation: take a break. Their tall singular trunk sprouts an almost comical head gracefully swaying in the ocean breeze—a perfect companion to heat, sand, and a cold glass of something to relax by.
Of course, if you don't vacation in the southern regions, you can always enjoy the blue variety found in Wildwood, New Jersey. Sometimes, you just gotta have a palm tree to really feel you'r on vacation.
