Clouds here at the moment. Not sure my eyes can stay open much longer as well

While reading about polynyas and 1974 and then searching for the Great Climate Shift of 1976 ... I ran across this, which I don't remember seeing before ... published on WUWT in 2013. The Great Climate Shift of 1878wattsupwiththat.com/2013/10/04/the-great-climate-shift-of-1878/It has this rather interesting graph ... Figure 7 – Solanki et al, Nature 2004 Figure 2. Comparison between directly measured sunspot number (SN) and SN reconstructed from different cosmogenic isotopes. Plotted are SN reconstructed from D14C (blue), the 10-year averaged group sunspot number1 (GSN, red)

The Carrington Event - a really strong direct hit from a CME occurred in 1859 The Sun has just had a series of strong CME's Perhaps something in the mechanics of the Sun's orbit causes its normal unvarying TSI to suddenly demonstrate that it is a variable star? We could be in line for a 'Great Climate Shift' in the opposite sense.

The above idea of a step change falls nicely in line with the chaos diagrams you posted not so long ago Naut.

The above idea of a step change falls nicely in line with the chaos diagrams you posted not so long ago Naut. My thought too. Now see this first diagram is a 'simple' two strange attractor type chaotic system Now what happens if one of those strange attractors has a state that could let the system start orbiting a third or fourth attractor? So what if there is a Glacial attractor, a stadial attractor and an interglacial attractor and we have been orbiting around the interglacial attractor - warm period, cool period, warm period, cool period then in a cool period if the states are 'right' we could move to a glacial attractor, or, even a stadial. Interesting thoughts

Might provide that extra impetus to get those starships built.

Interesting thoughts Spot on. You have more eloquently, more in depth and with better graphics explained an idea that rattled round my head for a while!

www.sciencedaily.com/releases/2014/11/141119204521.htmResearchers have shed new light on the climate of the Little Ice Age, and rekindled debate over the role of the sun in climate change. The new study, which involved detailed scientific examination of a peat bog in southern South America, indicates that the most extreme climate episodes of the Little Ice Age were felt not just in Europe and North America, which is well known, but apparently globally. The research has implications for current concerns over global warming.
