In this timely book, international scholars and military professionals come together to explore the strategic consequences of the thawing of the Arctic. Their analyses of efforts by governments and defence, security, and coast guard organisations to address these challenges make timely and urgent reading. Rather than a single national perspective, this book brings together circumpolar viewpoints from Europe and North America for an integrated discussion of strategic military, diplomatic, and security challenges in the high North. Thoughtful analyses are included of different regions, climate issues, institutions, and foreign and security policies. This is an important book for students of international studies, political science, and northern studies.
