Drawing on transnational theory, critical climate justice, and emotional geographies it examines how individuals experience climate anxiety through cross‐border ties, uneven vulnerabilities and relational forms of care. In doing so, the paper advances a framework for transnational climate anxiety that recognises it as socially, spatially and temporally embedded beyond the nation‐state.\n\nABSTRACT\nClimate anxiety is increasingly recognised as a significant emotional response to climate change. However, dominant conceptualisations remain largely individualised, future‐oriented and rooted within the spatial boundaries of the nation‐state. Such approaches overlook how climate‐related distress is shaped through transnational social relations and experienced unevenly across interconnected geographies. This omission is particularly significant for diasporic and transnational populations whose emotional, familial and material ties extend across borders and connect them to climate‐vulnerable regions elsewhere. Drawing on insights from relational geography, transnationalism, diaspora studies, and climate justice scholarship this paper develops a conceptual framework for transnational climate anxiety. It argues that climate anxiety is not solely a response to anticipated environmental futures but produced through networks of care, responsibility and vulnerability that link people to distant places affected by climate change in the present. In doing so, the paper reconceptualises climate anxiety as relational, multi‐sited and embedded within broader histories of inequality, migration and colonialism. The paper extends existing understandings of climate anxiety beyond individualised psychological models to advance a more geographically informed account of climate‐related emotional life. It concludes by proposing an applied framework to analyse how climate anxiety is lived, felt and negotiated across transnational spaces. By foregrounding transnationalism as an analytic lens, the paper addresses the marginalisation of diasporic perspectives in dominant climate discourse. It advances the concept of transnational climate anxiety as a necessary extension of existing scholarship and calls for a reorientation of climate frameworks to centre transnational lived experience by recognising climate anxiety as socially, spatially and temporally embedded in everyday life.\n"]
