I keep hearing about small island nations that are supposed to sink, but I'm not sure which ones are actually experiencing this right now in 2026. Are there any that have already become uninhabitable or relocated their populations?
Tracking which islands are actually sinking versus facing future risk requires looking at specific cases rather than hype. Tuvalu and Kiribati are the ones most visibly dealing with this - parts are already becoming uninhabitable, and both nations have been negotiating climate migration agreements (Kiribati notably made deals with Fiji and Australia for potential relocation). The Maldives, while facing real threats, hasn't relocated populations yet but is investing heavily in adaptation. A few smaller Pacific atolls like parts of the Marshall Islands have seen some communities relocate, though it's often complicated by politics and economics rather than being purely about sea level rise. So yes, it's happening to specific island nations right now, not just a future scenario.
