Introduction
International politics has been shifted enormously into a new episode in the mid 20th century in the history of International Relation. Before 1950s world politics was confined within frequent wars including two world wars. But after 1950s world politics, including cold war was filled up by many variants to ensure each states security as arms race, nuclearization as well as security against global climate change. Like all other things, global climate change also got a strong basis of global agenda in international relations specificly in 1972. Since then international relations and global climate change have become very intimate to one another to be discussed. By 1972 and having a remarkable benchmark in 1992, global environment as well as global climate change is being practiced almost with every aspect of international relations which include state, non-state actors, domestic international relationship, various political approach, several global accord, security and world trade as well. In this paper, we will try to find out the intensity of the intimacy between international relations and global climate change through several different approaches. In the beginning of the paper we will survey on the theories of international relations through which both international relations and global climate change can be explained then the discussion will be shifted to the role of state and non state actors on climate change, which will be pursued to the effect of climate change on human activities and the history of global climate change co-operation. Then we will move to an analysis of the global climate change regime through the several grand theories of international relations. Having theoretical analysis the paper will look forward to the domestic-international relationship on the global climate change negotiation and the political approach to climate
