Walt Johnson is a fifth-generation Coloradan and independent geophysicist consultant based in Denver. After graduating from the Colorado School of Mines in 1966 with a degree in geophysical engineering, Johnson spent approximately 50 years in geophysics, working with major and minor oil companies and pioneering digital seismograph technology used today to create sound-based images of the earth's crust.
Throughout his career, Johnson has published over 20 papers on shear-wave seismology, inversion, and detection techniques, establishing himself as a respected voice in earth sciences. His technical expertise has contributed to advances in how geophysicists understand subsurface structures.
In his 70s, Johnson embarked on a new career as a documentarian, investing approximately $200,000 of his retirement savings to produce "A Climate Conversation" with filmmaker Colton Moyer. The documentary examines climate science through historical data and expert analysis, featuring Kim Monson from The Kim Monson Show as interlocutor. The film uses a Socratic questioning approach to explore questions about climate change, its causes, and policy implications.
Johnson partnered with The Heartland Institute on the documentary and recruited credentialed experts including Greg Wrightstone and Ken Gregory. The film received a standing ovation at The Heartland Institute and aired on Newsmax, reaching audiences across the political spectrum.
Johnson has appeared on the Kim Monson Show to discuss the documentary's creation, the scientific arguments it presents, and the economic implications of climate policies, including the estimated $269 trillion cost of achieving net zero emissions.
