Uncertainty of future South Pacific Island rainfall explained
With greenhouse warming, rainfall in the South Pacific islands will depend on two competing effects -- an increase due to overall warming and a decrease due to changes in atmospheric water transport -- according to a study published in the 28 October online issue of Nature Climate Change by an international team of scientists.
