These voicemails save lives

For residents of Prek Touch, Cambodia — right on the banks of the Mekong River — flooding is a regular part of life. But as those floods worsen due to climate change, it’s getting harder to adapt. Along with other flood-prone regions throughout Southeast Asia, government officials are facing an issue: how to deliver widespread weather warnings in a timely, effective way. One solution that’s working for Prek Touch? Voicemails. Today on the show, NPR climate correspondent Rebecca Hersher explains how a simple phone alert can prompt preparation, increase evacuation, and save lives.
