Explain how climate change would weaken or even stop the gulf stream.

This strong current of warm water influences the climate of the east coast of Florida, keeping temperatures there warmer in the winter and cooler in the summer than the other southeastern states. Since the Gulf Stream also extends toward Europe, it warms western European countries as well. It will also melt more ice, decreasing the saltiness and making it less likely to sink. Combined, these factors can ultimately stop the circulation from overturning, taking the Gulf Stream with it. ... Currently, climate models indicate that the Gulf Stream will weaken but won't shut down entirely this century, if ever.
