alcom says... But if only 3% of Earth's water is fresh water, and 70% of that is currently frozen, that's a long, slow wait for a slightly less salty ocean. I don't think your dilution theory "hold water." I agree though, it could take decades, centuries or longer. notarobot said: But all the ice won't melt. By the time all the ice gets melty, the freshwater will dilute the salinity of the oceans. Once diluted, the oceans will be be slightly less good at conveying heat from the equator to polar regions, which means the poles will get colder and start to accumulate ice. Now this process may take a long time. Could be decades. Could be centuries. Could be longer. But it will happen.
