There is substantial evidence that wildlife is being affected by climate change. As a group, migratory wildlife appears to be particularly vulnerable because of the use of multiple habitats. The United Nations Environment Programme (UNEP) Convention on Migratory Species (CMS) is the only global agreement dealing with this problem.
'Migratory Species and Climate Change: Impacts of a Changing Environment on Wild Animals' contains contributions from experts around the world, exploring the current state of knowledge and looking at what can be done in mitigation. It also has a case study on marine turtles, which are already showing an increased rate of tumours caused by warmer waters.
