Atmospheric Warming Changing Ocean Salinity
Humans are messing with the water cycle, and the water cycle is messing with ocean salinity. As the atmosphere warms up the wetter parts of the world get wetter and the dryer parts get dryer, and this is directly effects ocean currents etc.
Properties such as: warm air can absorb more water vapor, salt water is denser than pure water and thus it sinks below the fresh water, are having a effect on the climate.
The changes observed are worrying: the temperature itself won’t faze anyone, but we’ll all get worried when the places which need the rain see even less of it, less water for irrigation, drinking and industry.
