1.looking at the heat circulation in the ocean, what might happen to it if large amounts of cold water are added in the polar regions as glaciers melt? 2.based on your response above, what effect could this have on the climate in your area?

1. Cold water from polar regions will sink and the warm water from equator will flow over it

2. Temperature of the area will increase thereby making the climate hot

Explanation:

1.Density of water plays an important role in its sinking. Water coming from Polar Regions is cold and therefore it has high density due to which it sinks down and move with a slow pace towards the equator. Thus, addition of cold water from Polar Regions causes the warm water coming from equator to flow easily towards the pole thereby sinking the cold water.  

2.This will increase the temperature of the surrounding/native areas due to rise in temperature of surface ocean water

yes, because even though a theory has a  lot of evidence to support it, it is not always true
