Although the harmful effects of climate change on human rights are well-recognized, the legal response to the climate crisis has been inadequate. This is particularly problematic as the crisis disproportionately affects vulnerable groups, which is exacerbated by a lack of effective remedies in contesting the adverse effects of climate change. The article argues that vulnerability theory offers a persuasive framing for rethinking what kind of remedies can be considered effective in the context of the climate crisis. A vulnerability theory approach (...) shows how vulnerability increased by the climate crisis is universal but differentially distributed. Effective remedies are an essential part of responding to this vulnerability. The article suggests that characteristics of an effective remedy include the ability to contest breaches of positive obligations, speediness, the ability to contest future harms, the ability to contest breaches of extraterritorial obligations, bindingness, and equality of standing.
