TL;DR: The authors empirically test existing theories on the provision of public goods, in particular air quality, using data on sulfur dioxide (SO2) concentrations from the Global Environment Monitoring Projects for 107 cities in 42 countries from 1971 to 1996.

TL;DR: In this article, the authors examine whether democracies contribute more to the pro-vision of global public goods than the free-rider problem, discounting of future benefits of climate change mitigation, and other factors that cut against efforts to reduce emissions.

TL;DR: In this article, the authors focus on four areas in which we know less: institutional design features that may help in mitigating or overcoming fundamental problems in the global cooperative effort; factors that are driving variation in climate policies at national and subnational levels; driving forces of climate policy beyond the state, in particular civil society, the science-policy interface, and public opinion; and sociopolitical consequences of failing to avoid major climatic changes.

TL;DR: In this article, the authors present a review of the literature on whether and how environmental changes affect the risk of violent conflict and highlight the most important challenges for further research on the subject.

TL;DR: A recent review article reported a remarkable convergence of scientific evidence for a link between climatic events and violent intergroup conflict, thus departing markedly from other contemporary assessments of the empirical literature.
