Using a new model, solar scientists believe we may be heading for a “mini ice age” in 2030. With the model, they’re able to predict solar cycles with a far greater accuracy, as it shows the irregularities in the Sun’s 11-year heartbeat.
Scientists say that the Sun will likely experience a Maunder Minimum effect in 2030 that will effectively put the Sun in a “sleep” cycle. The last Maunder Minimum occurred in 1646, which resulted in London’s River Thames freezing over, wrote Inquisitr.
According to The Carbon Brief, the Sun’s activity rises and falls on an approximately 11-year cycle, but it can experience longer variations from one century to another. Over the past 10,000 years, the Sun has hit around 30 periods of very high or very low activity—called “grand maxima” and “grand minima.”
Solar cycle—the Sun’s 11-year heartbeat explained:
One of these occurred between 1645 and 1715, when the Sun went through a prolonged spell of low solar activity known as the Maunder Minimum. This didn’t have much of an effect on global climate, but it was linked to a number of very cold winters in Europe.
Professor Valentina Zharkova presented his findings at the National Astronomy Meeting.
Zharkova stated that a mini ice age may soon be upon us.
The researchers monitored sun spots and solar activity for changes, and drew on “dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone. “The scientists have claimed that their model has a 97 percent accuracy rate.”
Zharkova found that in approximately 2030, the Earth would be entering a phase of little solar activity; the reason for this is because the two layers of the Sun will be exactly out of sync during its Cycle 26. This will reduce solar activity by approximately 60 percent.
Scientists forecast coming grand minimum solar cycle:
“In cycle 26, the two waves exactly mirror each other—peaking at the same time, but in opposite hemispheres of the Sun,” said Zharkova. “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.”
“Effectively, when the waves are approximately in phase, they can show strong interaction, or resonance, and we have strong solar activity. When they are out of phase, we have solar minimums,” Zharkova added. “When there is full phase separation, we have the conditions last seen during the Maunder Minimum 370 years ago.”
The new study was published in the open-access journal Nature Communications. So what are your thoughts? I guess it won’t be too long before we know if it’s a real threat. Would you be ready for a “mini ice age” in 2030?
