I thought three rings meant it was time for a Rhinegold.

Oh, sorry, it said "tree rings". My bad.

Where white males around during the middle ages? You don't need anything other than white males to cause all sorts of problems.

I have not had time to read the current issue of "Science." I am about 4 issues behind!

The article points out what I have stated in earlier posts: that ambient atmospheric temperatures and ambient ocean temperatures don't always "track" over time. With tree rings, the relationship with "warmth" is pretty well established, but cloud cover, brightness of the sun light (an effect of upper atmospheric scattering), etc., are also factors in ring development.

The article also points out the MYTH that ambient temperatures have been consistent until recently. Consider that natural processes such as volcanic activity can affect world-wide temperatures by 2-3 degrees F, the so-called global warming process is still a theory without a solid scientific basis in fact!

Guess there is no need to ping you on this thread. Nice post.

Sure, this is why the Vikings were able to found thriving settlements in Greenland at the time. When the warm weather ended, the settlements had to be abandoned.
