Final answer:
Ocean currents can influence climate by either warming or cooling nearby regions.
Step-by-step explanation:
Ocean currents have a significant influence on climate. Warm ocean currents can warm the nearby region, while cold ocean currents can cool the nearby region. For example, the warm Gulf Stream current brings warm water from the tropics to the North Atlantic, moderating the climate in Western Europe. On the other hand, the cold California Current brings cold water from the north, which cools the coastal region of California.
