October: (LK Comment: Found this excellent USG website recently which provides links to details about the effects of climate change in the Pacific and elsewhere. This portion focuses on freshwater issues)
The ability of people, plants, and wildlife to thrive on Pacific islands is tied to the amount of precipitation each island receives. On time scales from months to decades, climate variability and change affect precipitation patterns across the region. On even the smallest islands, freshwater is necessary to support plants, animals, and any human inhabitants. On developed islands, natural sources of water must also support agriculture, industry, and tourism. Relatively high demand for these uses means that water supply is constrained and may become more limited as climate changes.
