I see the graphed trend. I also see an increase in wavelength.
A thought: In the Sun’s gravity “dimple” do we see a fifty year cycle? Meaning:

Our entire system rotates. Is it possible, dare I say, we might see a pole over pole solar rotation? Due en parte’ to gravitational “dimple ripple”.

Well, we are much better able to cope in this day and age. So I am not as pessimistic as some.

But, no, not good. and it would likely result in badness, moral and otherwise.

Dodgy Geezer asks why will a little ice age be morally bad?

Because in past little ice ages, governments and people have done bad things.

I think it is excellent that this blogs opens up the discussion about the Sun and the effect of changing behavior of the Sun on the climate and it does it in its usual high quality manner. However, this is primarily a climate blog. Historical evidence indicates that the activity of the Sun as observed through sunspots affects the climate. We have a rare historical opportunity to observe this effect in real time – as long as the Sun continues to behave like it has for the recent past – and see if the low sunspot activity translates into an observable climatic effect. The AGW proponents by predicting rising temperatures as a consequence of the observed rise in atmospheric CO2 concentration created an ideal condition for the effect to be observed and be highly publicised if it indeed happens. However, trying to predict climatic changes is hard enough. Coupling it to trying to predict the behaviour of the Sun which is even less well understood than the climate, makes prediction more of a guess than science.
If the Sun continues its low sunspot activity and we have solid evidence that it influences the climate, that would be a major accomplishment. It would give a major impetus to understanding of the sunspot -climate link. It would also lead to trying to get a better understanding of the behavior of the Sun, which I do not believe that we currently have.

ERROR BARS: I keep meaning to post about error bars. I am concerned when I see charts like the one Figure 2 as it tells you nothing about the errors present in the measurements (maybe else where in their document but not in the post)

I could envisage a situation where the early measuring equipment was of poor quality and had large errors compared to the more recent data. If that were the case there might be no quotable trend at all.

Since this blog generally complains about the quality and repeatability of data, I think everyone should keep in mind that knowledge of errors of observation is critical when interpreting any data.

Anthony, I would like to see an updated graph of the Observed Geomagnetic Averaged Planetary Index. I think the last one you published was in mid-June. Now that July is almost over, and the sun has been really quiet this past month, it would be interesting to see if there are any signs of change in this index. Thanks.
