The Gulf Stream is a powerful warm ocean current that originates in the Gulf of Mexico and flows up the eastern coast of the United States before crossing the Atlantic Ocean. It plays a crucial role in regulating climate, particularly in Europe, by transporting warm water and influencing weather patterns. This current is part of a larger system known as the Atlantic Meridional Overturning Circulation (AMOC), which helps distribute heat across the planet. Changes in the Gulf Stream can have significant impacts on global climate, making it a vital area of study for scientists concerned about climate change and its effects on marine ecosystems.
