Its putting the cart before the horse. What came first? I consider the term adaptation to be a response [and hence a misnomer here], ie I adapted to a warmer climate. Can I "adapt" to a warmer climate before I move to a warm place?
No, but you will die, and those of your offspring that either get a lucky mutation in that generation, or that have a latent mutation that doesn't activate in the home environment, will survive.
