The two-volume publication is one of the first attempts to systematically address both international climate change law and global climate change governance. The two-volume publication deals with international law and the multiple regulatory regimes reflecting fragmentation in the absence of a universal climate change regime. International climate change law, global climate governance and diplomacy are interrelated and extremely complex: The publications explore these areas from a variety of doctrinal, transdisciplinary and thematic perspectives. Volume I assesses the most pressing impacts of climate change on various international law regimes. The main focus lies on - international climate change law as a new international law discipline; - climate change and human rights; - climate change, international trade and investment law; - the law of the sea and sea level rise; - judicial review and international climate change litigation; - other subjects such as mitigation regulation, natural resource management and climate-engineering. Volume II reflects on the United Nations Convention on Climate Change (UNFCCC) and the most pressing impacts of climate change on international diplomacy and global governance. This is highlighted from various transdisciplinary and geopolitical perspectives with a special focus on the challenge of strengthening national and international climate change policy, sustainable development and increasing equity around the world, which goes beyond the capacity of national governments. Various international climate change cooperation and protection efforts are analysed, also in the context of global security, climate induced migration movements, adaptation and the loss and damage debate.
