A tree-ring-width chronology was developed from Pinus tabulaeformis aged up to 333 years from central Inner Mongolia, China. The chronology was significantly correlated with the local Palmer Drought Severity Index (PDSI)…..
Significant relationships were found between our PDSI reconstruction and the solar radiation cycle and the sun spot cycle, North Atlantic Oscillation, the El Niño-Southern Oscillation, as well as the Pacific Decadal Oscillation.

There is also the progressive oscillation, wherein adherents direct their inner vibrations to a new spiritual reality as they starve in the dark.
Whatever… Some people need a religion to prevent them from being fearful of the unknown.
Interesting.
Not that I am skeptical but,
How many scientific research papers have been withdrawn lately?
I seem to remember another “Tree Ring Study” that folded, spindled and mutilated its data (throw out all the data for how many years, except one tree, really?)
The data magically fits all these cycles? Really?
I will believe it when I see it replicated
Not some people; all people without exception. It appears to be hardwired in humans to believe…. in something. Rational people pick Judeo Christian. Others pick aliens, global warming, conspiracy theories, whatever.But it appears to be a universal human trait to believe.
How about the church of practical earthly common sense?
or uncommon perhaps.
…or the Neo-Technic Church of the Presumptuous Assumption
I am having trouble interpreting the science jargon … so the science is confirming that driving cars and burning coal is wrecking the planet, and all deniers should be jailed !? Got it ! Excellent science ! Too bad the deniers are science illiterates.
And there were no idiot tree huggers/sitters back then like we have today that we know of sitting lotus style around the tree going OOOOOOMMMMM OOOOOMMMMM OOOOMMMMM like the eco-wackos do during their silly Earthday Celebrations
So non-AGW accounts for at least 40% of 1950-2012 change – that is, the non-AGW they “correlated” for this. Gosh, I can remember being told that even the Sun could not affect Globall Temperature!
knowing something is not the same as being able to do anything about bit. we have tornadoes, we know what causes them but we sure as hell can’t stop them.
97 percent of all idiots agree with this document.
