Some scientists have hypothesized that if enough ice in Greenland melts, the Gulf Stream might be shut down. Without the Gulf Stream to bring warm water northward, Europe would become much colder. Explain why melting ice in Greenland might affect the Gulf Stream.?

Explanation:

Scientists have been able to determine that the melting of ice from Greenland ice sheet will reduce the rate of Atlantic Meridional Overturning Circulation (AMOC) which is an important part of the global ocean current that determines the climate and controls Gulf stream. It as been inferred by researchers that this could affect climatic conditions in places like Europe and North America in the future.

The influx of fresh water from Greenland which is made up of runoff from ice, tundra and ice discharge will weaken the AMOC and this as both local and global effects on climate.
