There has been warming before, remember all those palm trees that used to grow up North????  Remember when the glaciers all melted back????

I don't believe anybody on this as the subject is more than any human can grasp.  If they could, why haven't they fixed it by now???

Thermohaline circulation is responsible for much of the distribution of heat energy from the equatorial oceans to the polar regions of the ocean. It is also the return flow of the sea water from the surface North Atlantic Drift and Gulf Stream currents.
