This article justifies and restates the non-identity problem in relation to climate change. First and briefly, I argue that while there is often good reason to set the NIP aside in practical politics, there can be areas where a climate NIP will have practical implications. An instructive example concerns climate change litigation. Second, I argue that there are three particular circumstances of a climate NIP that may set it apart from the more established NIP in bioethics. These differences regard interaction, (...) numbers, and agency respectively. Third, I discuss the premises and conclusion of a climate NIP, modifying an account in bioethics by David Boonin. (shrink)
