you're right about it being to do with salinity (salt content), it's called the 'Atlantic Conveyor', sea water is salty, salt water gets more dense when it cools, so when it gets to the Arctic it gets colder & sinks, this current of cold salty water goes back to the Gulf of Mexico, where it warms up, rises & flows back to the Arctic - where it cools down & sinks..............
Melting ice, due to 'global warming' dilutes the salt water, the theory is, that if diluted enough, it won't be dense enough to sink - and the Atantic Conveyor will be 'turned off'
Then without the flow of warm water we are used to, our latitudes would have a climate more like Canada.
