Plants survive within specific conditions. They depend on temperature, rainfall, and soil.
As climate changes, these conditions shift across geography. Suitable zones move toward the poles or climb to higher elevations.
Plants respond in three ways. They move, adapt, or disappear.
Movement sounds simple, but it is not. Seeds must travel. Landscapes must allow passage. New habitats must exist and support growth.
There are two aspects of this, one of which is flexible and the other not.
Flexible: In a fragmented environment, humans can help plants travel by reconnecting landscapes, protecting more wilderness, and sowing or transplanting species just past their leading edge of travel.
Inflexible: Mountains get smaller the higher you go. As alpine species creep upward, they lose territory. (The poles are smaller than the equator too, but they are enough bigger than mountaintops that this is less of an issue there.)
The part of this which every gardener can apply: Check the next zone warmer than yours for new plants you may wish to try in your yard to see if they will survive there now. Ideally, choose plants with a range at least one zone colder and one zone warmer to buffer against extreme swings. But if you've been hankering after something that almost survives in your locale, try it in a protected area like right next to your house.

That would do...interesting things to the climate here.
