'Over twenty years ago, when I first became interested in the impacts of climate change on wild plants and animals, the literature was limited and the field wide open. Now it is very hard to keep up. This marvellous book is exactly what I need to feel on top of the subject once more, and needs to be read not just by ornithologists, but by all ecologists struggling to understand and predict the impacts of climate change on the living world. The authors are two world-leaders on the impacts of climate change on birds. The text summarises the effects of climate change that have already happened, seeks to predict what we can expect in the future, and considers what conservation biologists can do to mitigate its effects. The coverage is comprehensive, and skilfully distils a large and complicated literature into a compelling … narrative.'
