If the pathologies of international relations (described in Chapter 3), especially those that derive from the nature of the international system, are not remedied, effective international cooperation to address climate change much more effectively will be elusive. If the pathologies of national politics (described in Chapters 4–6), especially narrow and short-term conceptions by states of their interests, are not modified to better comprehend the collective interest in mitigating the climate crisis for the benefit of people around the world, other attempts to govern the problem will be insufficient. If pathologies of human nature (described in Chapter 7), particularly overconsumption, continue to manifest themselves in the developed countries and spread metastatically to the developing countries, greenhouse gas pollution will be extraordinarily difficult, and probably impossible, to bring down to the degree, and with the speed, that is needed to avoid or at least mitigate dangerous climate change. This chapter conducts some diagnoses of the pathologies and explores some potential therapies for climate governance.
