The Sun is a cyclothymic system. Once every eleven years, it goes through what scientists call a solar minimum. This means that the Sun lowers its activity. The sunspots and solar flares are reduced to pin-point. The current one that started last year is presumed to be a very deep episode of solar minimum. Just as the former one was. Back in 2009, sunspot expert David Hathaway of the National Space Science and Technology Center NASA\/Marshall Space Flight Center said that "this is the quietest sun we've seen in almost a century." But the current one occurs at \u201ca rate surpassed only once before in the Space Age,\u201d as SpaceWeather.com reported. \u201cSunspot counts suggest it is one of the deepest of the past century,\u201d also said astronomer Tony Phillips. How to spot a solar minimum? The Sun\u2019s activity is measured by the changes that occur in its sunspots and solar flares. They indicate when the Sun is at its minimum or its maximum. The sunspots are regions of lower temperature and they indicate a specific magnetic behavior. The lower temperature on the Sun means 3000-4500 degrees Celsius. It sounds like a joke, but when compared with the usual 5500 degrees Celsius, it might become reasonable. Solar flares form around sunspots. They are abrupt flashes of brightness and often coronal mass ejection. As dangerous as they are, they are also necessary for space weather, and ultimately for Earth\u2019s weather. A Grand Solar Minimum can dramatically lower the temperatures on Earth. It isn\u2019t an easy job to identify the solar minimum. Scientists can only know about it six months after it occurs. To certify the Sun activity as a solar minimum, it has to be a constant behavior of the Sun that extends over a period of at least twelve months. So, what if the Sun is at its minimum? Like anything else in this Universe, the solar minimum has its good side as well as its bad one. Phillips said that the bad side is that \u201cthe sun\u2019s magnetic field has become weak, allowing extra cosmic rays into the solar system. Excess cosmic rays pose a health hazard to astronauts and polar air travelers, affect the electro-chemistry of Earth\u2019s upper atmosphere, and may help trigger lightning.\u201d Rumors are saying exaggerated things that involve expression such as "crop loss", "famine", "brutal cold", and even "Ice Age". But that\u2019s all they are: rumors. Social media trying to catch the reader\u2019s eye. NASA infirm those panic traps by saying that even if it \u201cwere to last a century, global temperatures would continue to warm.\u201d It seems that the Grand Solar Minimum can\u2019t compete with the greenhouse gases we produce. They would still make the global temperatures to rise. At this point, it looks like the solar minimum isn\u2019t a threat anymore but more of a providential aid. It would act like a counterattack to our Earth destroying behavior. Or so says the PennLive report. The second bad consequence is that this could encourage the main pollutant sources to continue to do so, or even to increase the rate.
