The Gulf Stream slowed down due to global warming

03.03.2021

Scientists have found that significant changes have taken place in the system of the Atlantic Gulf Stream, which bring heat to the territory of Europe.

We are talking not only about the current along the eastern coast of North America, but also about the entire system of Atlantic currents associated with it, affecting the northwestern coast of Africa, Western Europe, Scandinavia, the Barents Sea, and the Arctic Ocean. A study in the journal Nature Geoscience shows that the Gulf Stream has slowed to record levels over the past millennium.

Experts called the slowdown in the current sharp, as it happened contrary to all forecasts. At the same time, researchers associate this phenomenon with global climate change on the planet. Stefan Ramstorf from the Potsdam Institute for Climate Impact Research believes that the reason is anthropogenic influence on nature.

Over the past hundred years, the speed of the Gulf Stream has decreased by 15%. This has already affected the weather, in particular leading to more frequent heat waves in the south of Europe. Climatologists are concerned about this slowdown, because if the process continues, the circulation of the masses of water that form the climate in both hemispheres can be completely destabilized.

British Antarctic Survey oceanographer Andrew Meyers noted that before the onset of anthropogenic influence on climate, the overall system of the Gulf Stream was more stable. It is now being significantly affected by melting ice in Greenland and increased rainfall in North America.

"This indicates that the slowdown is likely not a natural change, but the result of human intervention," Meyers added. However, Tim Palmer, a climate scientist at the University of Oxford, believes that other factors also influence weather changes in Europe.

Accelerating the pace of global warming could eventually bring the Gulf Stream to a complete halt.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

TV prevents babies from learning to speak 13.11.2009

Employees of the Institute of Children's Health in Seattle (USA) installed automatic voice recorders in the families of 329 children aged 2 to 48 months. From the records it was possible to understand whether the TV was turned on, and to follow the conversations taking place in the apartment.

It turned out that during those hours when the TV was on, the children heard 500-1000 words less from their parents than when the TV was off, which slowed down the infants' language acquisition.
