Suppose that due to global climate change, the average minimum air temperature during January increased by 4°C. What would be the likely effect on the northern range limit for birds such as the eastern phoebe?

The northern range limit for birds is typically determined by the minimum temperature they can tolerate. If the average minimum temperature during January increases by 4°C, then the birds will be able to survive in areas that are 4°C colder than they could before. This means that the northern range limit for the birds will move farther north to the new ‒4°C isotherm.
