Embattled Climate Scientist Michael Mann Wins $1 Million in Defamation Lawsuit

Michael Mann secured a win in his legal battle against conservative bloggers who said the climatologist “molested and tortured data” and compared him to a convicted child abuser

CLIMATEWIRE | Climate scientist Michael Mann on Thursday secured a win in his long-running legal battle against conservative bloggers who once compared him to a convicted child abuser.

After a four-week trial, a D.C. Superior Court jury awarded the climatologist $1 million after finding that Rand Simberg, writing for the Competitive Enterprise Institute, and Mark Steyn, writing for the National Review, had defamed Mann in blog posts published in 2012. They accused Mann of manipulating the science around his “hockey stick” graph illustrating the exponential rise of global temperatures.

“I hope this verdict sends a message that falsely attacking climate scientists is not protected speech,” Mann said in a statement.

In a column posted in 2012 on the CEI website, Simberg had referred to Mann as “the Jerry Sandusky of climate science,” comparing him to a former Pennsylvania State University football coach who was arrested for sexually abusing young boys. Simberg said Mann had “molested and tortured data” on climate change.

Steyn later quoted Simberg’s column in a post for the National Review.

Mann sued Simberg and Steyn after their articles were published. The case has had a long journey through the courts, landing before the Supreme Court in 2019.

The justices declined petitions from CEI and the National Review to stop Mann’s case from advancing the Washington court, claiming First Amendment protections. Justice Samuel Alito said he would have taken the case, writing at the time that “a question of this nature deserves a place on our docket.”

CEI declined to comment on the D.C. Superior Court’s Thursday decision. Steyn’s manager, Melissa Howes, released a statement suggesting that her client would appeal the $1 million the court awarded to Mann.

Conservatives had framed Mann’s trial as though climate science itself were taking the stand.

“Climate Change Is ON TRIAL,” Ann McElhinney, the Irish filmmaker behind the documentary “Frack Nation,” wrote Jan. 11 on X, the social media platform formerly known as Twitter.

“Michael Mann & Mark Steyn will battle in court,” she continued. “The case will explore the hockey stick climate graph that rattled the world. Mark Steyn claims it’s a fraud. Michael Mann believes it is our future.”

An attorney for Mann said the writings from Simberg and Steyn had knowingly caused the climate scientist personal and professional harm.

“Today’s verdict vindicates Mike Mann’s good name and reputation,” said Pete Fontaine, chair of the environmental practice at the law firm Cozen O’Connor. “It also is a big victory for truth and scientists everywhere who dedicate their lives to answering vital scientific questions impacting human health and the planet.”
