Question

which event do many scientists believe would occur as a result of sea ice melting? ocean circulation would slow down throughout the world, oceans would cool down around the world, oceans would become less salty throughout the world, oceans life would grow at a tremendous rate

Answer 1

Ocean circulation would slow down throughout the world.

Reason: melting sea ice and ice sheets dump fresh, low‑salinity water into the ocean, reducing surface water density and weakening the thermohaline (density‑driven) circulation—notably the Atlantic Meridional Overturning Circulation (AMOC). That can slow large‑scale ocean currents and alter regional climates (e.g., cooling in parts of the North Atlantic), rather than causing uniform global cooling, a universal salinity drop, or a huge boost in marine life.
