In this article, I expand the existing discourse on climate justice by drawing out the implications of taking animal rights seriously in the context of human-induced climate change. More specifically, I argue that nonhuman animals are owed adaptive assistance to help them cope with the ill-effects of climate change, and I advance and defend four principles of climate justice that derive from a general duty of adaptation. Lastly, I suggest that even if one can successfully argue that the protection of human interests in adaptation ought to be prioritised, nonhuman animal rights will continue to place significant constraints on climate change action.
