(EGI Ed note: Well worth a read “global dimming” is probably behind tree-ring divergence post 1960.)
In November 2009, climate skeptics had their day in the sun when an anonymous hacker posted years worth of emails sent back and forth between some of the world’s most prominent climate scientists, working with theClimate Research Unit (CRU). Buried within these thousands of emails were a handful of fragments that skeptic seized on as proof positive that climate scientists had fabricated the idea of man-made global warming. After the emails were made public, a media frenzy ensued; “Climategate” culminated in deep investigations into the legitimacy of the science that backed of the theory of a man-made global warming. Ultimately, the CRU scientists were acquitted of any malfeasance, and their science was verified to be clean, but the events had a significant impact on public perception.
Five years later, a new study published in Nature Communications may help cool the lingering fallout from Climategate. The study, led by Alexander Stine of San Francisco State University and Peter Huybers at Harvard University provides a compelling scientific explanation for the issue at the center of the 2009 controversy: the tree-ring divergence problem.
