The history of climate change policy and politics refers to the continuing history of political actions, policies, trends, controversies and activist efforts as they pertain to the issue of global warming and other environmental anomalies. Dryzek, Norgaard, and Schlosberg suggest that critical reflection on the history of climate policy is necessary because it provides 'ways to think about one of the most difficult issues we human beings have brought upon ourselves in our short life on the planet’.
