This book presents a comprehensive overview of the history, definition, causes, effects, impacts and implications of climate change on young people globally, with a focus on Small Island Communities (SIDS) in particular. The text highlights the key problems associated with the impact of climate change on young people in SIDS, specifically its effects on socio-economic development and livelihoods, and explores the need for the development of a new conceptual framework to deal with building the resilience of the adaptive capacity of youth in SIDS. The book analyzes the strengths and weaknesses of the emerging phenomenon of Global Youth Climate Change Movements/Actions, and examines the management/governance challenges associated with the Movement in terms of its operational mechanism, mobilization strategies and its use of social media/technology to mobilize mass action. The text concludes with a recommendation for further research in this area as a way to understand how the Movement functions and its mechanism for implementation of future research. .
