Underestimation of volcanic cooling in tree-ring-based reconstructions of hemispheric temperatures : Nature Geoscience : Nature Publishing Group

[Mann et al, published Feb 2012] Our findings suggest that the evidence from tree rings is consistent with a substantial climate impact2, 3, 4, 5 of volcanic eruptions in past centuries that is greater than that estimated by tree-ring-based temperature reconstructions.

now talking about "missing" volcanic cooling in tree ring record. paper here

Twitter / alexwitze: D'Arrigo: @MichaelEMann pa

D'Arrigo: paper is "highly questionable." Questions entire science of tree ring dating. Misleads public.

Τop world seismologist who ALERTED in time 88 CRIMINALLY INDIFFERENT governments about the mega-quake in Japan last year, now supports* our position that Earth climate is regulated by [AVERTIBLE] galactic electricity.
AVERTING electric quakes caused by DIVERTIBLE solar flares to avoid Fukushima explosion and humankind extinction, is a PLANETARY EMERGENCY!!! PLEASE share and improve the TESTED, SIMPLE and anti-parasitic SOLUTION: *"Νow, thanks to the involvement of scientists from other fields of science including biology and astrophysics in preparations for the report, it has become apparent that the currently observed events are of galactic scale and are directly related to THE POSITION OF THE SOLAR SYSTEM IN OUR GALAXY, the Milky Way. It is this position that has a major impact on the formation of geological megacycles during which planet-scale biodiversity change is observed".
