Climate change continues to have profound impacts on people’s health, lives and life prospects. For the most part, people who are at highest risk from the impacts of climate change have contributed very little to the problem. This is the crux of the injustice. After I discuss the risks and contributions associated with the injustice of climate change, I turn to the issue of responsiveness: of why and how people should respond to this injustice. I avoid discussions of legal liability and focus more attention on the need to take political action to change social structures and habits. However, I realize how political engagement can prove to be ineffective, burdensome and dangerous. So in the last section, I say more about the reasons and changes that limit the effectiveness of political engagement. I suggest how we might change both the perception and practice of politics. At the end, I note two issues that I have not addressed in this limited article.
