Species will change their range

Mark Urban : evolutionary biologist
To take the example of North America, under the Intergovernmental Panel on Climate Change's (IPCC's) predictions, the climate we are used to seeing in the southern United States will pick up and move northward. North America's temperature gradient will shift northward. Some organisms will move with it. These emigrants will be organisms that haven't inhabited their current range for very long, thus limiting the time they've had to adapt to local conditions. They will also have bodies built for movement, like birds, wolves and, as we'll see next, insects.
