Once melting glaciers shut down the Gulf Stream, we will see extreme climate change within decades

Ocean currents are driven by winds, tides and water density differences. In the Atlantic Ocean circulation, the relatively warm and salty surface water near the equator flows toward Greenland.…Continue readingOnce melting glaciers shut down the Gulf Stream, we will see extreme climate change within decades
