McPherson's career as a professor began at Texas A&M University, where he taught for one academic year. He taught for twenty years at the University of Arizona,[8] and also taught at the University of California-Berkeley, Southern Utah University, and Grinnell College. McPherson has served as an expert witness for legal cases involving land management and wildfires.[9] He has published more than 55 peer-reviewed publications.[10] In May 2009, McPherson began living on an off-grid homestead in southern New Mexico. He then moved to Belize in July 2016. He moved to New York in October of 2018.[11]

In November 2015, McPherson was interviewed on National Geographic Explorer with host Bill Nye.[12] Andrew Revkin in The New York Times said McPherson was an "apocalyptic ecologist ... who has built something of an 'End of Days' following."[12] Michael Tobis, a climate scientist from the University of Wisconsin, said McPherson "is not the opposite of a denialist. He is a denialist, albeit of a different stripe."[13] David Wallace-Wells writing in The Uninhabitable Earth (2019) called McPherson a "climate Gnostic" and on the "fringe,"[14] while climate scientist Michael E. Mann said he was a "doomist cult hero."[15]

We are introduced to Guy McPherson and Paul Kingsnorth, called “climate Gnostics” by Wallace-Wells, both of whom have dropped out of society to await the climate rapture. It seems that Wallace-Wells introduces these “fringe” characters to normalise his own apocalyptic vision, as if to say: You think I’m out there? Look at these guys.
