The controversy about this issue of the earth experiencing "mini ice age" in the next 11 years started from Valentina Zharkova who is a professor at Northumbria University in the United Kingdom. She showed the sun's solar cycle model for the span of 11 years that goes through solar radiation periodic changes. According to Yahoo News, it came from the model that predicted that its solar activity diminished by 60 percent and the change was last seen in 1645.
From RAS, Zharkova said "We found magnetic wave components appearing in pairs, originating in two different layers in the Sun's interior. They both have a frequency of approximately 11 years, although this frequency is slightly different, and they are offset in time. Over the cycle, the waves fluctuate between the northern and southern hemispheres of the Sun. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97%."
The phenomena that Zharkova describes it as the "Meander Minimum" and she discussed this fully in the meeting of National Astronomy in North Wales. According to the definition by Brittanica, Meander Minimum is an "unexplained period of drastically reduced sunspot activity that occurred between 1645 and 1715." It was also said there that due to this phenomena, the Thames River in England froze and Viking settlers then left Greenland.
In the recent article published by Washington Post, though there has been research of the sun's unusual behavior in the coming years by Zharkova but the occurrence of "mini ice age" was clearly not stated by her.
According to Daily Time Gazette, Gifford Miller, a geological sciences professor said that "it is unlikely that the decreased solar radiation caused the Little Ice Age."
The "mini ice age" craze is not true.
