FEATURE - Islands battle rising seas for survival

SYDNEY (Reuters) - The Carteret Islands are almost invisible on a map of the South Pacific, but the horseshoe scattering of atolls is on the front-line of climate change, as rising sea levels and storm surges eat away at their existence. 

For 20 years, the 2,000 islanders have fought a losing battle against the ocean, building sea walls and trying to plant mangroves. Each year, the waves surge in, destroying vegetable gardens, washing away homes and poisoning freshwater supplies.
