Blake Francis is a PhD Candidate in the Philosophy department at Stanford University. His research interests include political philosophy and environmental ethics. His dissertation, “Climate change and the moral significance of harm,” develops an apparatus for identifying the harms of climate change and assessing their moral significance by working within the ethics literature on the nature of harm. This apparatus is then used to compare the diverse impacts of climate change to different people at different times. Blake's project both contributes to the literature on the ethics of climate change and presents a framework for evaluating climate change policy.
