New paper that has another take on past solar activity (would be interested in Sami Solanki's take on this):
Green Grok's take:
Not sure I agree with that interpretation - climate sensitivity may be higher but there might be other forcings (eg - high volcanic activity) which drove LIA cooling. Anyway, interesting stuff.
|Was going to say the same thing - it certainly isn't indicative of low sensitivity at least.|
The other take from this is it might give more support to the idea that there is a greater impact from solar cycle variability than previously thought.
Perhaps something with a cumulative effect so there is a time lag associated with the effect so that longer quiet periods have a greater impact than short ones. That might explain why it doesn't seem as apparent from the normal solar cycle but showed up in the last cycle.
I'm not so much suggesting Svensmark's GCR/Clouds idea but possibly other effects from Solar variability - UV levels and Ozone for example.
But really just speculation.
Full paper here. I take it the "skeptics" are getting their panties in a twist over this?.
