In the movie The Day After Tomorrow the main character(Jack Hall) faces a big issue. The North Atlantic current stops in the movie and then it does affect climate so in reality is it possible for the North Atlantic Current to stop and then affect climate. The ocean affects climate in vary many ways. The cold water in the North Atlantic Current sinks to the bottom and goes all around the world the cold sinking water is replaced by warm water at the surface that moves towed the north poles. What dose the north Atlantic conveyor belt do? It moves warm water form the equator (an imaginary line drawn directly in the middle of the poles, separating the southern and northern hemispheres) to the poles and cold water from the poles back toward the equator .
The amount of salt in the ocean also affects ocean currents. Saltier water is heavier and more dense than less saltier water. When the salty water in the oceans freeze, the ice can no longer hold on to the salt. Alternatively the salt mixes with the water under all of the ice and makes that water more salty, heavier, and more dense. Having water both cold and salty makes it really heavy, so it sinks very far. If to much ice melts in the North Atlantic the water would become less salty. There-for the North Atlantic does have an affect on climate if the conveyor belt were to stop.
