Surface temperatures in the western North Atlantic: Most of the North American landmass is black and dark blue (cold), while the Gulf Stream is red (warm). Source: NASA The Gulf Stream is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and flows through the Straits of Florida and up the eastern coastline of the United States, then veers east near 36°N latitude ...
Much of the heat transfer in the Atlantic occurs due to the Gulf Stream, a surface current that carries warm water northward from the Caribbean. While the Gulf Stream as a whole is driven by winds alone, its northern-most segment, the North Atlantic Current, obtains much of its heat from thermohaline exchange in the AMOC. [3]
A potential consequences of a weakening Florida Current could be higher sea levels and more flooding in Miami, the U.S. east coast and the Bahamas.
Wind-driven surface currents (such as the Gulf Stream) travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows into the ocean basins. [3]

First, the Gulf Stream and North Atlantic drift would generate a cordon of warm water around the North Pole, which in turn holds in a frozen mass of Arctic air.Second, if the North Atlantic drift were to shut down [broken anchor], that barrier would fail, releasing a flood of frozen air into the Northern Hemisphere, causing a sudden and drastic temperature shift.
The Gulf Stream current moves a massive amount of water across the Atlantic Ocean. According to Stefan Rahmstorf, one of the study's authors, it moves nearly 20 million cubic meters of water per ...
View of the currents surrounding the gyre. The North Atlantic Gyre of the Atlantic Ocean is one of five great oceanic gyres.It is a circular ocean current, with offshoot eddies and sub-gyres, across the North Atlantic from the Intertropical Convergence Zone (calms or doldrums) to the part south of Iceland, and from the east coasts of North America to the west coasts of Europe and Africa.
