“”McPherson is not the opposite of a denialist. He is a denialist, albeit of a different stripe. To watch him at work and to watch Tony Watts is to watch birds of a feather. Not evidence-based policy but policy-based evidence. Not part of the solution. Part of the problem.

—Michael Tobis, climate scientist

Guy McPherson (1960–) is Professor Emeritus of Natural Resources and Ecology & Evolutionary Biology at the University of Arizona. An author, blogger, and parallel universe version of Bjørn Lomborg, McPherson theorizes that runaway climate change constitutes a near-term human extinction event primarily due to "the consequences of taking down more than 200 species each day: at some point, the species we take into the abyss is Homo sapiens". McPherson first gained notoriety in the mid 2000s by predicting the end of civilization in under a decade due to peak oil, but as that failed to materialize he's switched gears to climate, and has gained a cultishly persistent following in the deep ecology/"doomer" fringe of the hard green movement. His blog is called Nature Bats Last.

According to McPherson, current climate data demonstrates that it is far too late to cut down on carbon emissions and mitigate the 40-year global warming process; accelerating climate feedbacks could cause a global average temperature increase of between >1° and >6° Celsius. This could eventuate in humanity dying out by 2030 at the latest although as of 2016 he makes it clear that he considers 2030 as a conservative estimate and that it won't be "business as usual" many years before that date. So apocalypse could begin within the next couple years or maybe the next couple years after that and so on. You decide. McPherson cites Paul Beckwith as saying that the earth could warm by 6°C in a decade and believes that a warming of 4° to 6° C will result in "a dead planet". He predicts an even greater rise but argues that anything more would be more than enough to do the worthless eaters in anyway. This will amount to a recreation of the biotic disaster of the "Great Dying" when micro-organisms were the dominant form of life for many millions of years.

Criticism

Analysis of the data by knowledgeable science educators such as Scott K. Johnson and working scientists such as Michael Tobis shows that McPherson wildly distorts climate science — especially developments about methane emissions from the Arctic — to support his conclusions. They also refute his claims related to runaway climate "feedbacks" as, variously, "not fast enough", not meeting the technical description of positive feedbacks, or actually constituting negative feedbacks. Additionally, Tobis points out that some of McPherson's statements — such as one nonsensical prediction of chain nuclear meltdowns — have literally nothing to do with climate science.

McPherson also claims that the United States government, and virtually all high-profile scientists and activists (like James Hansen), know we are beyond the point of no return, but are purposefully making conservative predictions to mislead the public. He also claims that he was under surveillance by the NSA when he was teaching and was nearly assassinated to avoid spreading the truth. Radio host Alex Smith explored the problematic reasoning and possible motivations behind McPherson's nihilistic views and also researched dubious sources of the purported extinction date, on the weekly Ecoshock program.

A quick review of any of the comments McPherson et al. make on critical articles, or the edit history of this very page, reveals that McPherson and his followers are quick to react to criticism with the predictable set of ad hominem attacks ("white male science," etc.) rather than with rational, peer-reviewed, or otherwise widely accepted scientific arguments. McPherson himself — again, see his apparent attempts at vandalism — admits to cherry picking data that support his views.

Manipulation and alleged sexual abuse of followers

McPherson solicits donations from his followers, which he uses in part to tour the world and give talks. On social media, he took on the role of grief counselor to help his followers emotionally cope with his claims of doom. A joint statement from several ex-followers summed this up as, "[McPherson] is in a position of authority with direct influence over the mental, emotional, and in some cases physical and monetary lives, of those who exist in a state of vulnerability." In August of 2017 McPherson was accused of sexual harassment by several ex-followers, who claim that his counseling with women often includes sexual advances or abuse. Deep Green Resistance, a radical deep ecology group, was disturbed after finding that he called one woman a "cum-gargling whore", and will no longer work with him.

Fellow traveller

In an interview, both McPherson and Paul R. Ehrlich claimed that the world was losing its ecosystems in an unprecedented way. Ehrlich claims that our survival chances are at maximal 10% — McPherson calculates less than that. Ehrlich previously made failed predictions of global famine in the 1980s; that should give you a good indication of the reliability of McPherson's even more pessimistic outlook.

Predictions

• In 2007 McPherson predicted the USA's trucking industry would collapse by 2012 due to peak oil, quickly followed by the interstate highway system.
• In 2008 he predicted the end of civilization by 2018 due to peak oil, "If you're alive in a decade, it will be because you've figured out how to forage locally."
• In 2012 he predicted that global warming will kill much of humanity by 2020.
• In 2016 he predicted that humanity and most lifeforms will be extinct due to global warming by mid-2026.
• In 2017 he predicted that global temperatures would be 6° C above baseline in mid-2018 and that Earth would have no atmosphere by the 2050s.
• In June 2018 he implied that industrial civilization was about to collapse in September 2018, followed by a 1 degree C immediate additional temperature jump due to the end of reflective aerosol production, which would rapidly somehow end all "complex multicellular organisms" on Earth.

Extinction

McPherson's podcast website, Ecoshock Radio, went kaput some time around 2017. The web address was subsequently bought by a sleazy penis enlargement company. As of 2019, his personal website was still touting his 2015 European speaking tour.
