Fluctuations in Ocean Salinity Could Forewarn of Climate Change

Significant increase or decrease in ocean salinity could forewarn of climate change in 10 to 20 years time, researchers say. The results, presented at a recent European Science Foundation (ESF) conference states that a build up of salty water stimulates deep-water circulation, while a dilu...
