To Donald Trump and plenty of others, climate change remains a hoax. More intelligent lifeforms - reptiles, birds and mammals - know better and they're on the move. In our case that path takes them northward, out of the U.S. and, for most, into Canada.
The Nature Conservancy has used data from two studies to chart all the routes these creatures are most likely to take as they migrate. Yellow is for reptiles; blue is for birds, and the purple represents mammals.
We have already seen the migration of marine life - fish, marine mammals and seabirds along our east and west coasts. Marine life faces fewer obstacles to migration than terrestrial creatures.
