Coerthas, to me, always looked particularly hardy, let's say. It's mountainous, but it was green and lush. It's possible the sorts of things they'd grow and raise there could have adapted. It's not as if, say, Cosa del Sol suddenly froze overnight. Maybe their wild life and agriculture shifted slightly instead of immensely.
