Spring comes to the Arctic two weeks earlier, on average, than it did a decade ago thanks to global warming. Global warming affects the Earth’s poles much more strongly than it’s lower latitude regions. A study of plant flowering, insect emergence and bird egg laying shows that for some species Spring arrives as much as 30 days earlier.

Home is where the temperature is right as far as plants are concerned, even when great expanses of Arctic Ocean are in the way. An Arctic Island plant study shows that the limiting factor for species migration during climate change is the local climate, not how far the seeds have to go to get there.
