Fun in the sun?

Daily Mail:

The study says that between 2020 and 2030 solar cycles will cancel each other out. The model of the Sun’s solar cycle is producing unprecedentedly accurate predictions of irregularities within the Sun’s 11-year heartbeat. It draws on dynamo effects in two layers of the Sun, one close to the surface and one deep within its convection zone. Researchers, led by maths professor Valentina Zharkova at Northumbria University, built up on previous research that predicts magnetic waves produced by the sun.

The model predicts that the pair of waves become increasingly offset during Cycle 25, which peaks in 2022. During Cycle 26, which covers the decade from 2030-2040, the two waves will become exactly out of sync and this will cause a significant reduction in solar activity.

It is 172 years since a scientist first spotted that the Sun’s activity varies over a cycle lasting around 10 to 12 years. But every cycle is a little different and none of the models of causes to date have fully explained fluctuations. Many solar physicists have put the cause of the solar cycle down to a dynamo caused by convecting fluid deep within the Sun. ‘In cycle 26, the two waves exactly mirror each other – peaking at the same time but in opposite hemispheres of the Sun,’ said Dr Zharkova in 2015. ‘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.’

Ah, yes: Michael Mann and the MWP, Newsweek in 1975, human sacrifice dogs and cats living together, and so forth.
