Heeding scientists’ warnings, the members of the United Nations in the early 1990s initiated a collective effort to address what they had determined was the urgent threat of climate change. This course will describe the means chosen to advance that effort, focusing on the 2015 Paris Climate Agreement and actions taken after its adoption. The Paris Agreement frequently is mentioned in public discourse, including campaigns for public office. This course will seek to present information helpful for developing an in-depth understanding of the Agreement’s specific provisions, the policy considerations underlying them, and the global political context in which the Agreement was negotiated and adopted. The course will not assess the contentions supporting or rejecting acceptance of the scientific determinations that underlie the effort to construct an international system of effective climate change governance.
