Solen aktivitet sjunker 2030 - ny miniistid?

En modell av solcykeln visar tydligt att solaktiviteten minskar med 60% under 2030-talet på samma sätt som skedde under den lilla istiden som började 1645. Det framgår av en studie publicerad av Royal Astronomical Society (RAS).

Science Daily: Solar activity predicted to fall 60% in 2030s, to 'mini ice age' levels: Sun driven by double dynamo.

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.
