    • Steven, I don’t know a lot about the Solar Cycles, but I’d like to suggest you look at http://www.landscheidt.info/?q=node/50 .

      If you scroll down it gives you a graph in several colors that compares the current Solar Cycle24 with earlier ones. The current big deal is that SC5 in shocking pink 200 years ago occurred during the Dalton Minimum, which was a more severe period during the Little Ice Age.. As you can see SC24 is about as bad.

      However the association of cooler temps w fewer sunspots is not so direct. The insolation doesn’t vary greatly whether the sun is in maximum or minimum. The current theory is that when the sun is less active (fewer spots) the solar “wind” is reduced so that it allows passage of more cosmic rays into our atmosphere. The increased cosmic rays cause formation of more clouds (shade). It is this that reduces insolation reaching the surface. However, since the ocean makes up about 70% of the surface it takes a long time for them to cool, and in the meantime they moderate any cooling of the air– or so we hope.

      Some people, including our host on this site think that serious cooling can happen very quickly. And we’ve already been cooling since about 2006, altho it’s been masked by El Ninos.

      Sorry if I am telling you things you already know. Perhaps it’ll be useful to someone else.
      Regards.

  2. Wyoming seems to be more or less normal except more rain & snow than usual. Cheyenne avg for May 65hi/40lo.
    Frost probability 50% thru May 12; 10% thru May 26.
    Centennial May 60/33 is avg, but nighttime is getting down to April avg lo of 24. Frost probability is 90% thru May 30.
    Of course in most cases I can’t go back to see if it was colder couple days before. Useful links just to see what info’s available.:
