Fascinating read.

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. Results will be presented today by Prof Valentina Zharkova at the National Astronomy Meeting in Llandudno.
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. Now, Zharkova and her colleagues have found that adding a second dynamo, close to the surface, completes the picture with surprising accuracy.
"We found magnetic wave components appearing in pairs, originating in two different layers in the Sun's interior. They both have a frequency of approximately 11 years, although this frequency is slightly different, and they are offset in time. Over the cycle, the waves fluctuate between the northern and southern hemispheres of the Sun. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97%," said Zharkova.

Would be nice to be around to see this happen.  This sure would set G/W back.

Yep, it is proof that Co2 is a following component, not a forcing issue of heat like the Marxists promote.
Like smoke on fire, smoke follows fire, it does not start fires.

And then we get treated to loons wearing Eskimo get-ups screaming it's too cold to pump Alaskan Pipeline oil for heating our homes. Oh. Wait. Mixed my metaphors.

Certainly will be interesting to see how the climate/weather goes here in the NE..  Give it time quiller, if the Democrats stay in power they'll have the media spin more pipeline projects as more jobs programs created by their brilliant minds.....while we continue on with NAFTA's legacy.

Isn't it exciting to see what we have to look forward to???   

oops.... what was those dates?  2030s.... hmm.... that might be stretching it a bit for me...

  Tell me about it.
