Case Overview

Fictional, set in the present day. Developed countries, including the United States, have been releasing greenhouse gasses into the atmosphere since the dawn of the Industrial Revolution. In recent decades, rapid economic growth in major developing countries such as China, India, and Brazil has led to significant increases in their own greenhouse gas emissions. The Intergovernmental Panel on Climate Change (IPCC), the U.S. National Academy of Sciences, and the federal government, have concluded that the warming observed in recent decades is a consequence of human activity. The effects of this global warming or climate change pose risks not only to the environment, but also to the security and livelihoods of people in the United States and around the world, both now and in the future. Various international responses are possible, but the questions of how to cut emissions and prepare for climate consequences, and who should bear the costs of doing so, have few simple answers. The U.S. government has convened a National Security Council (NSC) meeting to consider what goal to pursue at an upcoming international climate summit that the president plans to attend. NSC members will need to weigh the options, bearing in mind the potential impact of climate change, the potential effects of proposed measures to limit or prevent it, and the need to secure international support for the U.S. approach from both developed and developing countries.
