Question

if wastage (melting and calving) of the Greenland Ice Sheet were to dramatically increase, how would the salinity of the adjacent North Atlantic be affected?

Answer 1

Salinity of the North Atlantic decrease as the Greenland ice water gets mix up with it.

Explanation:

Global warming is the cause of the shifts in environment and climate. Melting of glaciers increases the water level and reduces the landmass. The melting of polar ice along with glaciers across Greenland and other regions, increases sea levels slowly.

As the melting glaciers and calving increases, and enters into the sea, it's created a situation where seawater in high latitudes is less salinity and less dense. It shows that the North Atlantic has become fresher over the past many decades.
