Tree Rings: A Proxy Of Global Paleoclimate.

Evidence to support Mann's Law of Dentroglobalpaleoclimatology

Morgan Wright OD et al

Abstract

The use of tree rings as a proxy of global temperatures is the gold standard, and has been shown to be scientifically robust and rigorous. This study gives further evidence of the robustitude and rigorosity of Mann's Law.

We used a single Tsuga canadaensis specimen in upstate New York. Slow growth between 1970 and 1983 was due to a cold period in Earth's history, known as the Global Cooling Scare. During Climategate, scientists used the Nature trick to hide the decline, but the decline was real, as we show here.

Slow growth between 1937 and 1955 was also due to global cooling during the cold war. In 1953, 1954, and 1955, the rings are so close they can barely be seen. This extremely cold period was because it was a VERY cold war.
