Highlighting the connections between climate change and human security, this book elucidates possible outcomes such as a sudden inability to produce enough food, rapidly advancing desertification producing water scarcities where none existed before, and greater demands for energy, resulting in increased air pollution. The destabilising effects of these possibilities create many potential challenges for national security in a globalised world, which we may lead to greater military intervention. This book offers a broad examination of the meaning of climate change and global warming while maintaining a strategic perspective on the implications of environmental effects on all forms of security - national, international, and human (transcending borders and having more to do with basic resources). Given the uncertainty surrounding climate change as a specific event, the authors argue for recognising the profound social, political, and human impact that could take place in the coming years. While recognising the inherent dangers of prediction, the authors effectively present the case that the time to not only recognise - but deal with - potentially profound outcomes is now.
