The impact of ocean currents on global climate is significant as they regulate temperature and weather patterns across the planet. Currents transport warm and cold water throughout the oceans, influencing regional climates. For example, the warm Gulf Stream raises temperatures in Western Europe, while cold currents can have cooling effects elsewhere. These currents play a crucial role in nutrient distribution, affecting marine ecosystems and fish populations. Additionally, fluctuations in ocean currents can significantly impact climate change dynamics and may intensify extreme weather events.
