Proxy studies show that a warmer climate is caused by wider tree rings. The correlation was perfect until 60 years ago, when tree rings were replaced by USHCN adjustments as the primary driver of climate.
Tree rings also show that the climate has been (until recently) completely stable – which is why all rings are identical.
i keep waiting for mann’s paper demonstrating that elephant tusks are make from piano keys.
lol, dissing our tree-ometers! No way! For instance, just by looking at the tree ring #8, I can tell you that year the average temperature anomaly was -0.365 deg C. Give or take a few thousandths of a degree or so.
If those rings are from the magic pine trees used by Briffa, they are teleconnected to the entire globe and can provide a detailed summary of climatic conditions across both hemispheres. Someone should come up with an app that can read these things from our smart phones.
The accuracy is equal to Palmistry or Phrenology with a bit of Numerology mixed in!
It is good to 5 decimal places but that was to extreme for their X-BOX so they settled for three decimal places.
Dr. Mann used special glasses made in Mordor to examine the tree rings. Of course he destroyed them afterword because if anyone other than the “Lord of the rings” was exposed to the power of these glasses they would become evil and turn insane for want of power.

The Tree Ring research APP is coming out for Wii this month at a Game Retailer near you. It comes with a digital virtual borer and a digital virtual micrometer. As a special bonus the first 5,000 units sold will have a Hockey Stick Template so you to can produce your own paleo reconstructions!!!!
I’m sure those are magic mushroom rings – not trees at all!
Rumor has it that I-Phone will also be launching a listening devise to listen in on the trees conversations. With in a short time they hope to complete the ability to carry on conversations with trees. Just think, rather than just hugging a tree you could get engaged an marry your favorite tree!
Steven:
They measure Late Wood density for a proxy unless you start a thread about late wood density and then it will be ring widths or better yet isotope concentrations in the cellulose structure.
