It is now beyond question that Arctic Region is experiencing an unprecedented and radical transformation. Due to the impacts of global warming, physical, climatic, and environmental conditions of the Arctic Region are rapidly changing. This rapid transformation of the icy conditions within the Arctic has increased the economic, environmental, social and political significance of the region within the last decades. Accordingly, once a peripheral and untended region for the global politics, today is becoming an inseparable part of the international political agenda. This book aims to provide a comprehensive analysis of evolution of Arctic Politics since 1980s; focusing on international cooperation, competition and conflict dynamics. It examines the emergence and development of international cooperation in the Arctic Region throughout the last three decades and interrogates challenges of this cooperation since mid-2010s and into more-troubled 2020s.
