A panel convened by Pennsylvania State University has mostly absolved Penn State climate scientist Michael Mann wrongdoing on allegations stemming from e-mails he sent as part of the Climatic Research Unit at the University of East Anglia e-mail theft last year, The New York Times reports:
In some of the e-mail messages, Dr. Mann refers to his assembly of data from a number of different sources, including ancient tree rings and earth core samples, as a “trick.” Critics pounced on the term and said it was evidence that Dr. Mann and other scientists had manipulated temperature data to support their conclusions.
But the Penn State inquiry board said the term “trick” is used by scientists and mathematicians to refer to an insight that solves a problem. “The so-called ‘trick’ was nothing more than a statistical method used to bring two or more different kinds of data sets together in a legitimate fashion by a technique that has been reviewed by a broad array of peers in the field,” the panel said.
The e-mail messages also contained suggestions that Dr. Mann had purposely hidden or destroyed e-mail messages and other information relating to a United Nations climate change report to prevent other scientists from reviewing them.
