The increasing pace of climate change in the last two decades has brought the Arctic, a former geopolitical afterthought, into growing prominence on the global stage. Receding ice and melting tundra have made a cornucopia of rare earth metals and hydrocarbons ripe for extraction as well as opened new shipping lanes which have the potential to revolutionize how goods are moved around the planet. In this emerging environment is a budding balance of power which involves the most powerful actors in the world-system, two of which, the United States of America and the People's Republic of China, are the focus of this thesis. Their respective arctic policies shape the balance of power for not only themselves, but for all other actors in the theater. The United States' laissez faire attitude towards the Arctic has caused it to fall behind the progress of other powers in the region which could make it difficult to assert its influence in the theater in the future. China however has chosen to follow an ambitious arctic policy despite its geographical distance from the region, and has given the arctic a prominent position in its greater Belt and Road project, much to the suspicion of traditional arctic powers. Analyzed through a realist lens, the balance of power in the Arctic appears to be stable for the...

The new fact that the environment is becoming the main factor of geopolitical transformations in the Arctic region has been triggered mainly by climate change. In the North, this recent aspect of geopolitics, in correlation with the environment, leads sometimes to tensions between countries, but also to a need for cooperation. The question brought by such conditions is, to which extent will this climate change provoke cooperation or conflicts between the Arctic states. The purpose of addressing the problem is to understand what kind of challenges would be facing the international relations between circumpolar countries and how the environment is playing a geopolitical role in them. The objective of the main research question is to assess the importance of climate change over the geopolitics of the Arctic through several spheres of geopolitics: environment and bio-diversity, economic activity of the region, sovereignty and territoriality, security of the circumpolar states, and international and diplomatic relations. The trans-border and transnational nature of environmental issues is another important factor, since nature does not respect human-made boundaries and an environmental concern, such as climate change and its aftermaths, cannot be exclusive to a state along the lines of its borders.
