Articles on the major climate change treaties, beginning with the United Nations Framework Convention on Climate Change (UNFCCC) at the Rio Earth Summit (1992). We review the Kyoto Protocol (1997), its ill-fated successor the Doha Amendment, and its successor the Paris Climate Agreement (2015). We look at the key aspects of each treaty, the list of parties or signatories, and assess its likely effect on global warming. In addition, we profile the Intergovernmental Panel on Climate Change (IPCC), the UN’s expert advisory panel on climate science, and its landmark Special Report on Global Warming of 1.5°C. We also review arguably the most successful of all environmental or climate change treaties, the Montreal Protocol on Substances That Deplete the Ozone Layer (1987).
