Michael Shellenberger
Template:PAGENAME Michael Shellenberger is an American journalist, author, and political commentator. He is founder and president of Environmental Progress, a research organization, and publishes the Public newsletter on Substack. He is the author of Apocalypse Never (2020), a critique of climate alarmism, and San Fransicko (2021), an investigation of homelessness and drug policy in San Francisco. He is also a Time Magazine Hero of the Environment and Green Book Award winner. In 2022 he ran for Governor of California as an independent candidate.
Background
Shellenberger began his career as an environmentalist and was instrumental in the founding of the Breakthrough Institute, a think tank that argued for high-technology, pro-nuclear approaches to climate change rather than the degrowth and anti-nuclear positions dominant in mainstream environmentalism. His willingness to challenge environmental orthodoxy — most specifically on nuclear energy — cost him standing in environmental circles before he embraced his heterodox positions publicly. He described his reluctance to publicly advocate for nuclear power — despite believing it was correct — as driven by fear of social backlash rather than cognitive error.
Twitter Files
Shellenberger was one of the journalists selected by Elon Musk to report on the Twitter Files — the cache of internal Twitter documents released beginning in December 2022 documenting the company's content moderation decisions, its relationships with government agencies, and its role in suppressing political speech. His Twitter Files reporting focused in particular on the Censorship Industrial Complex — the interlocking network of government agencies, NGOs, academic institutions, and technology platforms that he and co-authors Matt Taibbi and Michael Benz argued had coordinated to suppress disfavored speech online under the guise of countering "disinformation."
Shellenberger's description of the censorship mechanism described how the Department of Homeland Security (DHS), the FBI, and the CIA responded to the populist electoral shocks of 2016 — Brexit and the election of Donald Trump — by pivoting resources from counter-terrorism to what he termed "counter-populism": pressuring social media platforms to suppress disfavored views. The DHS specifically created third-party organizations at academic institutions — most specifically the Stanford Internet Observatory — to issue demands for mass content removals from Twitter and Facebook. The resulting system, dubbed the Censorship Industrial Complex, also produced what Shellenberger called the "CTIL Files" — internal documents of a counter-disinformation coordination infrastructure he argued constituted an unconstitutional government censorship operation.
The constitutional dimensions of this activity were being litigated in Missouri v. Biden — a Supreme Court case alleging First Amendment violations from government-coordinated platform censorship — at the time of his congressional testimony.
Congressional testimony
Shellenberger testified before the United States House of Representatives Select Subcommittee on the Weaponization of the Federal Government in 2023 regarding the Twitter Files findings. During the hearing, a Democratic congresswoman characterized the findings as "right-wing moral panic talking points," a dismissal Shellenberger rejected by reference to the documentary record — including direct emails showing coordination between government agencies, academic institutions, and platform trust-and-safety teams.
Apocalypse Never
Apocalypse Never (2020) argues that nuclear power should be central to climate change mitigation and that apocalyptic framings of climate change are scientifically overstated and politically counterproductive. Shellenberger describes himself as an environmentalist who became disillusioned with the mainstream environmental movement's opposition to nuclear energy.
San Fransicko
San Fransicko (2021) investigates the homelessness and open drug use crisis in San Francisco and other West Coast cities, arguing that progressive policies — particularly those emphasizing "harm reduction" over treatment and accountability — have worsened conditions for both the homeless and city residents. U.S. carbon emissions declined more than those of any other country between 2005 and 2021 primarily due to replacement of coal electricity with natural gas from hydraulic fracturing; Shellenberger has cited this as evidence that energy abundance, not scarcity, drives environmental progress.
UAP reporting
In 2023, Shellenberger testified before Congress on UAP-related matters. Steven Greer has alleged that an informant provided Shellenberger with a secret twelve-page document covering what programs internally designate "Immaculate Conception" — reportedly referring to the reverse engineering of recovered non-human craft — and that this document informed aspects of his congressional testimony on the subject.
