Ocean currents play a decisive role

Position 1: Scientists therefore monitor salinity and temperature gradients across the Atlantic as early indicators of systemic change.

Position 2: Warm surface currents transport heat from equatorial regions toward the poles, moderating temperatures in coastal areas such as western Europe.

Position 3: Disruptions to this circulation, potentially caused by the influx of fresh meltwater from polar ice sheets, could have far-reaching climatic consequences.

Position 4: Ocean currents play a decisive role in regulating the thermal balance of the Earth's climate system.

Position 5: Simultaneously, cold deep-water currents return along the ocean floor, completing a global conveyor belt of thermohaline circulation.
