In 2011, Science published a meta-analysis that showed 764 plants and animals were shifting to higher latitudes by 10.5 miles per decade. In North America, the National Audubon Society’s annual Christmas Bird Count echoed that data, showing that the 305 most common species of birds have moved their population centers north by an average of 35 miles over the past 50 years.
