Mainstream ethical debates concerning responsibility for climate change tend to overemphasise emissions and consumption while ignoring or downplaying the structural drivers of climate change and vulnerability. Failure to examine the political-economic dynamics that have produced climate change and made certain people more susceptible to its harms results in inapposite accounts of responsibility. Recognition of the structural character of the problem suggests duties beyond emissions reduction and redistribution – including, potentially, a responsibility to fundamentally restructure our political and economic institutions.

Much mainstream political philosophy assumes that states have a broad right to decide who is granted entry and membership into their political community. On this conventional view, admission of migrants and refugees is understood as mostly a matter of general humanitarian duty or voluntary beneficence rather than as a specific obligation of justice. Through an analysis of climate-related migration from Central America's Dry Corridor to the United States, I argue that many such migrants may in fact be owed admission as (...) reparation for injustice, and that the character of this injustice raises broader challenges for the conventional view.
