For many months, conservative lawmakers and political operatives have been targeting the scientists and lawyers behind the Climate Judiciary Project, a program meant to educate the courts about climate science, alleging that their effort constitutes a conspiracy to influence federal judges and persuade them to rule against the oil industry.

Now, just as congressional investigators are escalating a formal inquiry into the project, a separate program closely aligned with the fossil fuel industry and free-market conservatives is hosting a symposium for 150 judges in Nashville, Tennessee. The program, run by the Antonin Scalia Law School at George Mason University, also aims to educate judges, but in a way that prioritizes American business interests and questions climate science.

The dueling efforts come as a number of significant lawsuits seeking to hold fossil fuel companies accountable for climate damages are making their way through the courts and as oil-industry-aligned attacks on climate policies, and the legal arguments supporting them, have been sharply increasing.

ProPublica reported in April that political operatives connected to the conservative activist Leonard Leo were coordinating an effort across 11 states to pass laws shielding fossil fuel companies from liability for climate harm. In the past three weeks, similar liability waiver bills have been introduced federally in both the House and the Senate. Last week the Florida attorney general’s office launched an investigation into alleged judicial influence by the organization that oversees the Climate Judiciary Project, the Environmental Law Institute, a nonpartisan legal scholarship group funded until recently by the Environmental Protection Agency.

These developments come on the heels of a campaign last winter to get the Federal Judicial Center, the publishing body for the federal court system, to retract a roughly 90-page chapter devoted to climate science from the latest volume of its technical manual for judges. Twenty-two Republican attorneys general wrote to Rep. Jim Jordan of Ohio, the Republican chair of the House Judiciary Committee, demanding that the committee investigate the center’s publication of material about how to weigh scientific evidence about climate and the weather because the chapter’s authors appeared to be biased. In their letter, they noted the authors work for Columbia University’s Sabin Center for Climate Change Law and alleged the chapter was influenced by Michael Burger, the executive director of the center who works closely with the law firm Sher Edling, which represents several climate plaintiffs. The Republican attorneys general also noted that some staff at the Sabin Center work with the Environmental Law Institute and the Climate Judiciary Project. Although the chapter had been peer reviewed and approved by the Federal Judicial Center, as well as by the National Academies of Sciences, Engineering and Medicine, the center retracted the climate chapter in February.

On April 28, Jordan went a step further, issuing letters accusing Burger, the Environmental Law Institute and Sher Edling of bias, conspiracy and collusion. Jordan demanded that the three parties produce private communications, receipts and records of funding sources, and that the recipients sit for interviews before the committee.
