The scientists, who studied the composition of the waters of the Atlantic from Greenland to Tierra del Fuego, found that they have become "very much" saltier in the tropics and subtropics and "very much" fresher towards the poles over the past 50 years.
This is alarming because the Gulf Stream is driven by cold, very salty water sinking in the North Atlantic. This pulls warm surface waters northwards, forming the current.
The change is described as the "fingerprint" of global warming. As the world heats up, more water evaporates from the tropics and falls as rain in temperate and polar regions, making the warm waters saltier and the cold ones fresher. Melting polar ice adds more fresh water.
Apparently, similar "flips" have occurred before and caused cool periods in Europe. Due to the non linear nature of such a change, the cooling could come as fast as a decade or two. Watch out.

just google: coming ice age
I still think its rather egotistic of us humans to think we can control the climate on such a huge scale.
