Audio: Global warming threatens Pacific islands

Residents of small island nations threatened by rising sea levels bring their stories to the UN climate talks in Bali.

As polar icecaps melt, reports of unprecedented high tides are coming in from those living in low-lying Pacific islands, such as Tuvalu, Kiribati, and Papua New Guinea's Carteret Islands. There, creeping sea levels erode coastlines, engulf homes, destroy crops, and contaminate wells.

This week, residents of these small islands have come to Bali, Indonesia where they share their stories with representatives gathered for the UN climate conference.

Reporting from Bali, Peter N. Spotts discusses the islanders' plight.
