The chapter provides an introduction to issues associated with the relationship between second homes and climate change. A major problem identified in existing research is the lack of consistent definitions of what constitutes a second home within and between jurisdictions, which makes comparative research difficult. Existing research is geographically limited in scope although recognition of the environmental impacts of climate change has existed for many years although research on climate change related issues is much more recent. Two major strands of research exist. The first is the contribution of second homes to climate change, which is primarily the use of transport to access second homes. Private cars are identified as the major transport mode for domestic second home tourism. The second strand of research is the impacts of climate change and climate change related events on second home destinations. The latter reflects the majority of contributions to the present work.
