Deep Climate has more details, but I want to highlight one particular thing:
“Neither Dr. Wegman nor Dr. Said has ever engaged in plagiarism,” says their attorney, Milton Johns, by e-mail. In a March 16 e-mail to the journal, Wegman blamed a student who “had basically copied and pasted” from others’ work into the 2006 congressional report, and said the text was lifted without acknowledgment and used in the journal study. “We would never knowingly publish plagiarized material” wrote Wegman, a former CSDA journal editor.
Even if Wegman believed that the text in the Wegman report was original work, he’s still guilty of knowing plagiarism for lifting the text from the report into the paper without acknowledgement.
