" According to the Royal Astronomical Society (RAS):
A new model of the Sun’s solar cycle is producing unprecedentedly
accurate predictions of irregularities within the Sun’s 11-year
heartbeat. The model draws on dynamo effects in two layers of the Sun,
one close to the surface and one deep within its convection zone.
Predictions from the model suggest that solar activity will fall by 60
per cent during the 2030s to conditions last seen during the ‘mini ice
age’ that began in 1645. (source) "
