Experts are predicting that a ‘mini ice age’ is in store for our Earth and it’s coming really soon. They expect a 60% drop in solar magnetic activity within the next 15 years, adding that the current low levels of solar activity are something unseen since the mini ice age.
According to the Express, experts have designed a new model which allows them to make more accurate predictions regarding solar activity, something they weren’t able to do thus far. This new model shows that between 2030 and 2040 there will be a decrease of 60% in the magnetic activity on Earth.
The model focusses on the Sun’s ’11-year heartbeat’ – which is the time needed for magnetic activity to fluctuate. This cycle was first discovered about 173 years ago.
But, it seems that one mathematician has found a more modern model which can predict how the solar cycles will look just by examining the dynamo effects in two layers of the Sun.
What are dynamo effects, you ask? Well, it’s a term used for a geophysical theory that regulates how the Earth’s outer core movement conducts materials like liquid iron across the magnetic field to create an electric current, which also affects fluid motion under the Earth’s surface to create two magnetic fields along the axis of the Earth’s rotation.
A scientist from the North Umbria University, Valentina Zharkova, was able to apply this theory on the Sun and predict with 97% accuracy how the solar cycles will affect the Earth.
At the National Astronomy Meeting Ms. 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. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97%.”
According to Ms. Zharkova’s calculations the next cycle will have its peak in 2022, while the cycle afterwards, dubbed Cycle 26, will bring about a new ice age on Earth.
Ms. Zharkova continues: “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’.”
