If you are not frightened by the speed of climate change on our planet, the scientists just bring the matter to the end. Based on these data, experts warn about the approaching catastrophic solar superbreak. According to researchers, a powerful geomagnetic storm causing natural disasters, is inevitable in the near future. The effects of this solar storm can cause blackouts and even failures of the satellites. Unlike other threats to our planet, such as supervolcanoes or asteroids, the time frame for the occurrence of catastrophic geomagnetic storms, is relatively short. These storms can happen in 10 or in 100 years.
What is a solar storm?
The sun is the only star of the solar system and one of the many stars in our galaxy. Around the Sun revolve the heavenly bodies, including our planet. Feature of Earth is its magnetic field which protects us from solar and cosmic radiation. Planet with no magnetic shield no signs of life. As you know, each star has its own characteristics. So, in the Sun from time to time are active processes, such as flares, sunspots, coronal mass and the shock wave. Through these events occur, the energy of the particle. They scatter from our home star in many different directions. So some of them fall into the Earth’s magnetosphere. The collision of these energetic particles leads to the perturbation of the magnetic field, which we call a magnetic storm.
The main feature of magnetic storms is their influence on the entire planet. The excitement and magnetic shield lead to different consequences. The fact that together with the magnetic field of all the other layers of Earth’s atmosphere change. And because of the excitement of the ionosphere, plasmasphere and magnetosphere there are currents and energetic particles. The result of the induction effect caused by a magnetic storm may have disaster-related damage to conductive systems, such as pipelines and power lines.

Today experts consider the events of September 1859 the Carrington (USA), called superbra as the most powerful magnetic storm in the history of observations. However, new evidence suggests that the more recent magnetic storm in may of 1921 in its intensity could overshadow events in Carrington, causing at least three major fires in the U.S., Canada and Sweden. Researchers also obtained data on the destructive effects of solar storms to our planet.
What is the danger of magnetic storms?
In an article published in the journal Space Weather, experts have revised the intensity of the events of 1921, known as the “storm train”. Historical measurements of the magnetic storms is not easy. Today at the disposal of scientists around the world are tools for tracking magnetic storms, however, the knowledge of scientists about these processes until 1957 was based on meaningless data collected with different instruments scattered around the planet. In the new study, the researchers recreated the intensity of the storm 1921 with an accuracy never before seen.
The analysis, conducted by scientists shows that the impact of the new York railroad storm of 1921 was as serious as the events in Carrington. The fact that the storm of 1921 caused the occurrence of three major fires. One of them was caused by the interruption of the current in the Telegraph wires at the railway station in Brewster, new York and led to the fact that the station was burned. The second was the fire that destroyed the telephone station in Karlstad, Sweden, and the third occurred in Ontario, Canada.
What do you think, could a magnetic storm cause the end of the world? To speculate on this topic with members of our Telegram chat.
How to protect against magnetic storms?
Today, scientists monitor space weather with the help of NASA, such as the Advanced Composition Explorer. Thanks to data obtained from these devices, scientists cautioned that the approaching magnetic storm. This system allows the experts in advance to turn off the power or companions, as the storm approach to reduce its impact.
But if the Land would fall again the strongest magnetic storm, the consequences can be more serious, regardless of the warnings. The authors of the study believe that the effects of such solar storms can not be called a end of the world, but they definitely will cause a lot of destruction. Anyway, scientists are closely watching the space weather. According to scientists, in the last few years policy makers have begun to devote “due attention” to the problem. We hope that magnetic storms of such destructive power does not overtake our planet in the next 100 years.
