Unless you're among the growing number of Americans whose homes are powered entirely by renewable energy, every time you switch on a light you're doing your part to sink a Pacific island.
Many of the thousands of tropical islands that dot the Pacific Ocean are low-lying and will be among the first countries to sink as the world's seas continue their steady rise.
But beyond the risks posed to their very survival, these islands face additional acute threats from freshwater shortages, coral bleaching, higher temperatures, and other hazards wrought by climate change. This despite the fact that their inhabitants have low carbon footprints and are contributing relatively little to the climate problem.
It is against this backdrop that the U.S. has spent the past year preparing aid projects designed to help a dozen Pacific island countries brace themselves against the growing threats posed by global warming.
