sun could nod off by 2030, triggering what scientists are describing as a “mini ice age.”
Vlentina Zharkova of NorthumbiraUniversity presented the frigid findings at the
National Astronomy Meeting in Llandudno, Wales.Modern technology has
made us able to predict solar cycles with much greater accuracy, and Zharkova’s model predictsthat solar activity
will drop by more than half between 2030 and 2040.
activity was thought to be caused by a turbine-system of moving fluid within
the sun. In search of a more accurate system of prediction, Professor Zharkova
and her team discovered fluctuating magnetic waves in two layers of the sun. By
studying the data of the dualwaves, she says, predictions are far more precise.
“Combining both waves together and comparing to real data for the
current solar cycle, we found that our predictions showed an accuracy of 97
percent,” said Zharkova, whose findings were published by the Royal
this method, she and her team discovered that there will be far less solar
activity in sun cycles 25 and 26, leading to a prolonged period of solar
“In cycle 26, the two waves exactly mirror each other -- peaking at
the same time but in opposite hemispheres of the Sun. Their interaction will be
disruptive, or they will nearly cancel each other. We predict that this will
lead to the properties of a ‘Maunder
minimum’,” said Zharkova.
Maunder Minimum is the title given to periods of time when sunspots are rare.It last occurred
between 1645 and 1715, when roughly 50 sunspots were recorded, as opposed to
the standard 40,000. That time was marked by brutal, river-freezing
temperatures in Europe and North America.
