Michael Shellenberger (born June 16, 1971) is an American writer, environmental and political activist, and co-founder of the newsletter Public [1]. He is known for his work on energy and the environment, for co-authoring installments of the Twitter Files in 2022, and for books including Apocalypse Never and San Fransicko [1].
Within the UFO/UAP field he is best known as the journalist who in October 2024 published an anonymous whistleblower’s account of an alleged secret Pentagon program, Immaculate Constellation, and who delivered a 12-page report on it to Congress on November 13, 2024 [11][13]. The program’s existence has not been verified, and the Department of Defense says it has no record of it [14].
Early life and education
Shellenberger was born in Colorado to Mennonite parents and graduated from Greeley Central High School in 1989 [1]. He earned a bachelor’s degree in Peace and Global Studies from Earlham College in 1993 [2] and a master’s degree in anthropology from the University of California, Santa Cruz in 1996 [1].
Career
Activism and the Breakthrough Institute
After graduating he moved to San Francisco and worked on progressive causes, including a Nike boycott campaign with Global Exchange, and founded a nonprofit communications firm [1]. In 2003 he co-founded the Breakthrough Institute, an ecomodernist research center, with Ted Nordhaus [1]. Their essay The Death of Environmentalism (2004) argued that the American environmental movement needed a new politics [3], and he later co-signed An Ecomodernist Manifesto (2015) [4]. He later founded Environmental Progress, which campaigned to keep nuclear plants such as California’s Diablo Canyon open [1].
Books, politics and media
His books include Apocalypse Never (2020), which argues that climate change is serious but not an existential threat, and San Fransicko (2021), a critique of progressive homelessness policy [1]. He ran for governor of California as a Democrat in 2018, finishing ninth among 27 candidates with about 0.5 percent of the vote [8], and as an independent in 2022, finishing third with about 4.1 percent [1]. He co-founded Public and has written for The Free Press [1]. In December 2022 he was among the journalists who published installments of the Twitter Files with the cooperation of Twitter’s new owner [9].
UFO/UAP involvement
Shellenberger’s UAP work began with his reporting on anonymous government sources and led to testimony before the U.S. House of Representatives [1].
The Immaculate Constellation report (2024)
In early October 2024, Public published his account of a whistleblower who said the Department of Defense had been running a secret program called Immaculate Constellation, created in 2017, to collect information on UAP outside of congressional oversight [14]. The source’s identity was withheld; Shellenberger said sources spoke to him on background, and some alleged that the Executive Branch had managed UAP matters for decades without congressional knowledge [12]. Tim McMillan of The Debrief wrote on October 10 that the whistleblower’s claims were difficult to verify and that no conclusive evidence had emerged [16].
Congressional testimony (November 2024)
On November 13, 2024, Shellenberger testified before House Oversight subcommittees at the hearing “Unidentified Anomalous Phenomena: Exposing the Truth.” NPR reported that he submitted about 214 pages of testimony, including a timeline of UAP reports from 1947 to 2023, and called for transparency legislation and cuts to funding for undisclosed UAP programs [11]. In his opening statement he described the Immaculate Constellation report as identifying an active, highly secret Pentagon program, and Rep. Nancy Mace said he had delivered the original 12-page document to Congress that day, which was entered into the record [13]. The Debrief quoted him as telling the panel that the intelligence community was treating Americans like children [12].
Matthew Brown (2025)
In April 2025 filmmakers Jeremy Corbell and George Knapp introduced Matthew Brown as the author of the report Shellenberger had brought to Congress. A secondary analysis says Shellenberger, Corbell and Knapp reportedly vetted Brown, while noting that this speaks to the claim’s provenance and does not verify the program [15].
Reception and criticism
Critics of the UAP reporting, including participants in a Metabunk discussion, noted that the public record contained no evidence beyond Shellenberger’s account of what his sources told him, and that the Pentagon denied the program [14]. His earlier work has drawn criticism too: climate scientists such as Peter Gleick and the Science Feedback group disputed claims in Apocalypse Never [5][6], and reviewers gave San Fransicko mixed to critical assessments [7]. Reporting on his 2024 “Twitter Files – Brazil” series led to Brazilian scrutiny, and journalists later identified errors in it [10]. Supporters regard him as a reporter willing to bring contested government-secrecy claims to Congress.
Assessment
Documented: Shellenberger published the Immaculate Constellation account, testified on November 13, 2024, and delivered a 12-page document that was entered into the congressional record [13]. Claimed but unverified: that the program exists, that it holds UAP imagery, and that it has been hidden from Congress. The sourcing is anonymous or, in Brown’s case, based on one person’s recollection of a file not made public [15]. Readers should separate his role as a documented messenger from the unverified claims he relayed.
