10. The Maldives
The Maldives, a paradise of turquoise waters and white sand atolls, faces an existential threat from rising oceans. Most of the nation sits less than two meters above sea level, making it especially vulnerable to even slight increases in water levels. If current trends continue, entire islands could disappear beneath the waves. This dire scenario is shared by other low-lying island nations—such as Tuvalu and Kiribati—highlighting the urgent need for global climate action.
