In Proceedings of the National Academy of Sciences, scientists have created a scoring system to assess whether animals should be relocated to cooler areas to help animals survive on a rapidly heating planet. Although this idea was balked at in the past because interfering with present ecosystems could spell disaster, scientists now warn that the situation has become so escalated that action needs to be taken.
Two arguments back their position. First, scientists believe that the climate is changing at such a rapid rate that animals cannot evolve quickly enough to adapt to their changing environment. Second, because humans have altered the landscape so drastically with urban development, animals do not have the space to migrate north themselves.
