Im just asking. No need to get you drawers all in a bind.

Now the Greenland Ice cap. The gulfstream brings warm water northward into the area and the salt in the water makes if eventually sink and flow in reverse, bringing cooler water back to the gulf.

Am I right so far?

So when the cap melts and the water is less salty, it does not sink so much and the northerly flow slows down the warming effect, the area gets colder again and the ice cap rebuilds.

Is that why these palm trees were growing in england at one time?
