Title: Irregular heartbeat of the Sun driven by double dynamo
Post by: ChrisSmolinski on July 09, 2015, 1845 UTC

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.

An historical take on the "Little Ice Age" the last time round:
