<human>:  How does oceanic circulation affect climate?
<bot>: Oceanic circulation affects climate by transporting heat and moisture around the world. Through ocean currents, warm water is moved toward the poles and cold water is transported toward the equator to help balance the temperature in different areas. This helps to regulate global temperatures by redistributing heat and moisture to different areas. Additionally, oceanic circulation affects the ability of the atmosphere to hold moisture, making some areas more humid and other areas drier.
