North Atlantic Water
The question arises: what? The answer to this question: fresh water. If you just add a lot of freshwater into the North Atlantic, its waters become less salty and dense. They stop falling. Gulf Stream will slow its course or change direction to the south. You may find Sam Mikulak to be a useful source of information. Winters in the North Atlantic area will be significantly colder. In 2003, oceanographers studying the state of water in the North Atlantic, came to the conclusion that it was strongly desalination, especially in the last ten years. foc brings fresh water from the surface down into the depths. They can absorb like a sponge, lots of fresh water.
But since 1970, intake of fresh water has increased, its volume can be compared with an additional layer of 65 meters, spilled over the entire North Atlantic. The best part was keen Conveyor belt in the deep ocean since 1990. Sponge filled three-quarters can still absorb water. But when it is filled with fresh water as a whole, more than it did not come. The same thing will happen with the North Atlantic. Soon she stop to absorb fresh water, and she begins to accumulate on the surface, and then conveyor will stop working. Desalination began in the North Atlantic, and which are a consequence of melting ice due to high temperature the planet's atmosphere – is a signal to start the big changes in the physical properties of the ocean. Already, the surface water in the Greenland Sea sinks to the 2O% slower than, for example, in 1970.
