There was a time, not so long ago, when climate scientist Michael Mann could bully critics into silence with the mere threat of a lawsuit. He was the face behind the infamous “hockey stick” graph, a man lauded by progressives, featured in Al Gore’s documentary, and embraced by a media eager to label skeptics as dangerous deniers. But the courtroom, as it turns out, is no place for manufactured myths or moral grandstanding.
A Washington, D.C. court just handed Mann a bruising legal defeat. After more than a decade of litigation, he has been ordered to pay over $1 million in attorney’s fees to the very people he accused of defamation: National Review, the Competitive Enterprise Institute (CEI), and writer Rand Simberg, a former PJM contributor.
Even more humiliating, the court revealed that Mann grossly misrepresented his financial damages. Once celebrated as a martyr for the climate cause, he now stands exposed as a fabricator, not just of projections, but of personal injury.
The Graph That Launched a Thousand Grants
Mann’s rise to prominence began with a temperature reconstruction graph published in 1998. It erased historical warming periods such as the Medieval Warm Period and the Little Ice Age in favor of a dramatic 20th-century spike. To the casual observer, it looked like mankind had shoved the planet off a climate cliff.
The media ran with it. The United Nations’ Intergovernmental Panel on Climate Change (IPCC) elevated the hockey stick to icon status. Schools taught it. Politicians cited it. Al Gore plastered it in “An Inconvenient Truth,” like a gospel.
But critics soon noticed that something wasn’t right. Canadian researchers Steve McIntyre and Ross McKitrick uncovered glaring flaws in Mann’s methodology, showing that his algorithm could produce a hockey stick shape even when fed with random data. This wasn’t just bad science; it was political theater dressed in lab coats.
From Researcher to Legal Enforcer
Rather than engage in honest debate, Mann chose litigation as his cudgel. In 2012, he sued National Review and CEI after their writers criticized his work and compared how Penn State handled their investigations of Mann after the East Anglia emails leak, and of Penn State’s disgraced football coach, Jerry Sandusky.
This was not a matter of protecting one’s reputation from slander. This was a climate scientist declaring war on dissent. And for a while, it worked. The lawsuits dragged on for over ten years. Many media outlets pulled back from covering the criticisms, not out of agreement, but out of fear.
The recent rulings, however, dismantle Mann’s claims. The D.C. court awarded National Review $530,820.21 in legal fees. CEI and Simberg will receive $472,000. These were not sympathy payouts. They were direct rebukes of a man who tried to game the legal system as thoroughly as he gamed climate projections.
A Courtroom Beatdown
In one of the ruling’s most scathing parts, the court found that Mann and his attorneys misled the jury about the damages he suffered. He testified he lost grants, suffered financially, and had speaking engagements canceled because of the defamation.
But evidence showed the opposite. Mann’s career flourished during the litigation. His speaking fees increased, and his public profile soared. His hardship claim was a mirage, and the court wasn’t buying it.
