Early days yet and it could all go Pete Tong. However, the charts are fascinating and personally, I don't think it is a coincidence that we are in a deep solar minimum at the moment.
I remember a Radio 4 discussion when I was a teenager back in the early 70s and the topic of the discussion was the Maunder Minimum and the severe European winters which were associated with it. Even back in the 70s, they were drawing conclusions from that and the scientific evidence for such has only increased since then. Still not clear why there should be an effect, since total solar insolation only drops marginally during solar minimum - but two effects are noticeable - one is that UV reduces much more than other parts of the spectrum and the other is that cosmic ray penetration is much increased during solar minimum (as shown by 14C records in ancient and very old wood).
Why should reduced UV and enhanced cosmic rays be associated with northern blocking in the Atlantic (if those are indeed the drivers) - that is the question?
Just one other thing on this topic - it is not global temperatures which are hugely impacted by solar minimum, it is the regional effects which are noticeable, particularly in western Europe on account of the associated northern blocking.
