Topic: The circulation of the Atlantic was weakest in at least 1,600 years.
The influential Atlantic electrification system, which plays a key role in distributing heat across the Earth's climate system, is now moving at least 1,600 years slower than it has existed, according to a new study published in the journal. Nature Geoscience from the world's leading experts in the field.Scientists believe that part of this slowdown is directly related to our warmer climate, as melting ice balances northern waters. Impacts can be seen from storms, heat waves and sea-level rise. And it sparked concerns that if humans were unable to limit global warming, the system could eventually reach a tipping point and disrupt global climate patterns.The Gulf Stream along the east coast of the United States is an integral part of this system known as the Atlantic Circulation, or AMOC.
The film was famous for 2004's "The ดาวน์โหลด slotxo android Day After Tomorrow" in which the ocean currents stopped. All of a sudden, massive killer storms swirl across the world, such as the highly charged tornado in Los Angeles and its lurking walls of water. New York City.As in many sci-fi movies, the plot is based on a real concept. But the impact would be very severe. Fortunately, the tide is not expected to stop suddenly any time soon - if ever, even if it will eventually stop - and is highly controversial - the outcome will not be an immediate larger-than-life storm. But over the years and decades, the impacts will certainly damage our planet.Recent research has shown that circulation has been at least 15% slower since 1950. Scientists in the new study said that weakening electric "It never happened in the last millennium.
Since everything is connected, the slowdown is undoubtedly affecting the global system, and by the end of the century it is estimated that circulation could be 34% to 45% slower if we continue to heat the planet. Scientists fear that this kind of slowdown will bring us near a dangerous turning point.Importance of the Global Ocean Conveyor Belt Because the equator receives more direct sunlight than colder poles, heat forms in the tropics. In an effort to achieve equilibrium, Earth sends this heat north from the tropics and cools south from the poles. This is what makes the winds blow and storms to form.Most of the heat is distributed by the atmosphere. But the remainder is slower by the ocean in what is known as the Global Ocean Conveyor Belt, a global system of tides that connects the Earth's oceans, moving in all different directions horizontally and vertically.
Through years of scientific research,
it is clear that the conveyor section - AMOC - the Atlantic Ocean is the engine that drives its function. It moves the water 100 times the Amazon river flow. This is how it works A narrow band of warm, salty water in the tropics near Florida, called the Gulf Stream, is blown north, near the surface, into the North Atlantic. Upon reaching the Greenland region, it cools down enough to be denser and heavier than the surrounding water, at which point it will sink. Then the cold water will be blown south in a deep stream.Through proxy records such as ocean sediment cores, which allow scientists to recreate a distant past, dating back millions of years, scientists know that this current has the ability to slow and stop and when and where the climate. The air in the northern hemisphere can change very quickly.One of the key mechanisms over the years that acted as AMOC speed regulators was the melting of ice and allowing fresh water to flow into the North Atlantic.
That's because fresh water is less salty, so it's less dense than seawater and doesn't sink as quickly. Too much fresh water means that the conveyor has lost the sinking part of the engine and thus has lost momentum.That's what scientists believe is happening as Arctic ice in places like Greenland is rapidly melting due to human-induced climate change.Recently, scientists have observed a drop of cold water, known as the North Atlantic hot hole, in the North Atlantic area around southern Greenland, one of the only places to cool the world.The fact that climate models predict this gives rise to more evidence that it indicates melting of excess Greenland ice, greater rainfall and slowing heat transport north from the district. hot To make sure what the recent AMOC slowdown was, the research team gathered proxy data taken from natural archives such as ocean sediments and ice cores that date back more than 1,000 years. They rebuilt AMOC's flow history.
