Answer:
If large amounts of cold water are added in the Polar Regions as glaciers melt then the warm water has a more difficult time flowing north.
Explanation:
If large amounts of cold water are added to the Polar regions as glaciers melt, the main problem that would result from this is the fact that this would make it more difficult for warm water to flow north. This would alter the ecosystems of many regions. However, the impact would not be reduced to the ocean. As ocean currents also regulate temperature on land, many regions (most notably Europe) would experience significant cooling, leading to many problems for the animals and people that inhabit these regions.
