Two years after the District of Columbia Court of Appeals ruled that climate scientist Michael Mann could proceed with defamation claims against the authors and publishers of online articles, the appellate court responded to a petition for rehearing by issuing an amended opinion with only minor adjustments—the addition of one footnote and the revision of another. The appellate court thereby reaffirmed its conclusion that a reasonable jury could find that statements in two of the articles were false, defamatory, published by appellants to third parties, and made with actual malice. The articles accused Mann of scientific misconduct and compared his alleged misconduct to the conduct of Jerry Sandusky, a football coach at Penn State who was convicted of child sexual abuse. 

Defamation action brought by climate scientist against authors and publishers of articles about scientist's work.
