Scientists have theorized that warming of the earth's polar regions could slow down or even stop the global thermohaline circulation. which of the following explains why this could be true?

O as water moves north to the polar regions, it cools and sinks, creating a massive convection current.

O as water moves north to the polar regions, it warms and rises as the ocean currents circulate.

O warming of polar regions forces the movement of large schools of fish, causing the deep ocean currents.

O global thermohaline circulation is not affected by changes in the temperature of polar regions.
