Many of the world’s most iconic species migrate as part of their life cycles. Migration is key to the survival of these species; they are finely adapted to specific habitats that change with the seasons. It has been known for some time that climate change has the potential to adversely impact migratory species. This review presents a summary of recent scientific evidence that indicates that the impacts of climate change are being felt by migratory species now; and finds that these impacts could have catastrophic implications for many migratory species. It also highlights the contributions of migratory animals to healthy functioning ecosystems and nature-based solutions. The review is published in three parts, with an accompanying summary.
