The political-intellectual project of climate justice (CJ) is diverse in its analyses and proposals. Recently, some sympathetic critics have worried that, together with its often-contentious tenor, this polyvocality renders CJ incoherent and/or ill-suited to legal and policy application. Divergent choices of framing and means do matter, since they entail implications for the development of constituencies, alliances, and political, legal, and/or policy action. This paper argues, however, that rather than incoherence, the variation, fluidity, and complexity of CJ evidence logical adaptations to differing positionalities and circumstances, made necessary by the multiple, geographically varying dimensions of climate injustice. Critical political geographic perspectives (which happen to complement those of many movement adherents) help to expose this adaptive logic. Correspondingly, diverse articulations of CJ and their implications help show how political spaces and ecologies matter in contesting the multiple inequalities and power moves with which climate injustice is intertwined. Moreover, recent public health analyses and testimonies from affected groups suggest that shared experiences of rising, disproportionate climate-related death and other forms of individual and collective loss increasingly underpin and motivate CJ's multiple forms. The trajectories of compounding loss, still-rising greenhouse gas emissions, and the growing hegemony of CJ in a variety of settings underscore the need for continuing development of extensive solidarities among dispersed and differently positioned affected groups and potential allies. Though other approaches – including those which address climate injustices without naming them as such – may bear fruit, such extensive articulations of CJ are crucial needs that intellectual labor can help to meet.
