Climate Migration as a Security Threat: Preparing for Displacement Hotspots in the 2030s

Climate change is no longer just an environmental issue, it is rapidly becoming a global security concern. The commentary highlights how rising seas, floods, and droughts are forcing millions to migrate, creating emerging “displacement hotspots” across South Asia, Sub-Saharan Africa, SIDS, and Latin America. It explains how climate migration acts as a threat multiplier, intensifying resource competition, social tensions, and governance challenges. As existing refugee laws fail to protect those displaced by environmental causes, the commentary calls for proactive global preparedness through forecasting, cooperation, and sustainable adaptation to avert a security crisis in the 2030s.
