Chapter 12 explores the question: how do climate change and ethics intersect? This exploration begins by emphasizing that decisions to act require both scientific information and a value judgement; as a result, different people or societies with different backgrounds and values can reach different conclusions when considering the same scientific information. Public views in the U.S. about climate change range from alarmed to disengaged to dismissive. Organized public relations efforts have shaped this range of views and have generated denial of climate science and opposition to climate-friendly policies. Three primary ethical concerns applied to climate change are harm, justice, and concern for future generations. It is important for you to develop your own values and ethical responses to climate change, but it also is important that you develop the skills to discuss your values with others who may not share your values.
