Episode 56: A landmark ruling: What the ICJ's advisory opinion on climate change means for climate security

When the International Court of Justice delivered its landmark advisory opinion on climate change in July 2025, it did more than clarify legal obligations — it reframed climate action as a matter of human rights, justice, and global security. In this episode, we speak with Atieh Khatibi, PhD researcher project assistant at the Research Center for Climate Law (ClimLaw: Graz), University of Graz, to unpack what the opinion actually says, where its limits lie, and what it means for multilateral negotiations, domestic policymaking, and climate litigants worldwide. Drawing on her work in Iran, where climate stress, socioeconomic grievance, and political fragility intersect acutely, Atieh further reflects on what the opinion's reach looks like in contexts of active conflict and state fragility. We close by asking: what do high-emitting states, vulnerable nations, and civil society each need to do differently — and where is there reason for optimism? Further resources: The International Court of Justice's Advisory Opinion on Climate Change: A New Mandate for Climate Security (report) Read the advisory opinion and lastest developments © adelphi global, all rights reservedadelphi global (https://adelphi-global.de/en) is an economically and politically independent, non-profit organisation dedicated to promoting sustainability, enhancing environmental protection, improving education, expanding development cooperation, and strengthening international collaborations.
