This course covers the international law dealing with climate change with a view to assessing how risks and uncertainties caused by climate change are governed and allocated in different international law regimes. The course adopts the stance that the political and legal questions raised by climate change cannot be addressed by reference to climate change law (or international environmental law) alone. Climate change gives rise to a series of profound problems touching upon a range of bodies of international law (international economic law, human rights law, and state responsibility inter alia) in a complex political and ethical environment. In approaching climate change as a concrete concern relevant to these various bodies of law and practice, the course will address the normative and ethical bases for choosing between actions designed to prevent and/or manage climate change and its consequences, and the theoretical concerns raised by the 'fragmented' nature of international law.
