Scientist: The "minimum period of solar activity" has been confirmed, and the global temperature may drop soon.
The "solar minimum" will last for several solar activity cycles, during which the sun generates less energy and the sunspot activity is also low. During the previous minimum period of solar activity, that is, from 1645 to 17 15, the glaciers kept expanding, and the Thames in Britain often froze.
Zarco Wa predicted: "At present, the temperature of solar minimum will be slightly higher than that of maunder minimum, and this solar minimum will be shorter."
In a paper published on 20 15, Zarco Wa and her colleagues deduced a pair of principal components from the solar background magnetic field. They associate these components with a pair of magnetic waves from different levels of the sun.
Through more in-depth analysis, the research team deduced the timeline of these magnetic waves in reverse, and the results were very consistent with the activities of sunspots in the past 800 years. After that, she used the same method to predict the minimum period of solar activity in the next few decades.
As evidence to predict the minimum period of solar activity, Zarco cited the sunspot data of the Royal Observatory, as well as the recent low temperature and extreme climate. Including the coldest winter on record in Antarctica and the unusually cold and snowy weather experienced by Texas in early 20021.
In 20 19, NASA said that "the prediction of the next solar cycle shows that it will be the weakest one in the past 200 years", which is consistent with the sunspot activity from about 1790 to 1830 and the Dalton minimum period with relatively low global temperature.
However, the agency claims that if there is a minimum period of solar activity, "it can only offset the warming caused by human activities for several years."
However, Zarco believes that the minimum period of solar activity can reduce the global temperature by as much as 65,438+0 degrees Celsius.
She also said that the impact of carbon dioxide in the atmosphere may be a bit exaggerated. She pointed out that with the expected doubling of global life activities, carbon dioxide is increasing.
A recent study shows that the increase of atmospheric carbon dioxide content since 1940 has played a 40% role in increasing the yield of major crops in the United States.
Zarco Eva believes that governments in the northern hemisphere should prepare their citizens for the sharp drop in temperature in the coming decades.
However, at present, governments all over the world are ready to deal with so-called "man-made global warming". The recent COP26 summit in Glasgow, Scotland proved this point.
The current temperature record has always been a controversial issue. Satellite data collected by various sources, including the University of Alabama in Huntsville, the European Union and other institutions, show that the global temperature has been unusually high in recent decades. Many scientists believe that this is consistent with global warming caused by human activities. Other sources criticized some data, saying that the conclusion about man-made global warming is wrong, exaggerated or misleading.
Zarco Eva believes that at least some people involved in promoting global warming have begun to realize the possibility that the earth's land will become cold in the near future.
She said: "They want to get their money as soon as possible-taxes, or whatever they get from green technology-because they will be exposed soon."
