Why is democracy, the most common regime form around the world, so slow in handling the vital threat of climate change? What role do scientists play and should play in a democracy? How should we approach the question of climate and environmental justice both at the local level, where climate change and pollution have a differential impact on different socio-economic and racialized communities, and at the global level, where the countries and people most affected by climate change have the least say and the biggest culprits few incentives to change their ways? This course aims to explore the intersection of democratic theory, science, and climate and environmental justice from the perspective of an empirically-informed political philosophy.
