  • Joseph Fournier: “There is not one greenhouse effect; there are two” | Tom Nelson Pod #374
    Feb 22 2026

    Joseph Fournier presents “part two” on how Pacific Walker circulation controls Earth’s largest greenhouse effect: cloud longwave radiative forcing. He explains cloud radiative forcing terminology, cites literature claiming cloud greenhouse warming dwarfs CO2 forcing, and shows satellite-era links between trade winds, cloud shifts during ENSO, outgoing longwave radiation, and global/tropical temperature anomalies. He contrasts absorbed solar radiation, OLR, and Earth energy imbalance, arguing global averages can be dominated by regional Pacific dynamics. He reviews multidecadal “dimming/brightening” sunshine trends in Europe, Japan and the U.S., discusses aerosols vs natural drivers, and briefly addresses future uncertainty, AMO/IPO impacts, and solar/cosmic-ray hypotheses.

  • Jamie Andrews: “Control Studies” | Tom Nelson Pod #373
    Feb 18 2026

    Jamie Andrews discusses his journey from geology to virology, questioning the mechanisms and validity of virus transmission and pathogenic theories, especially in the context of the COVID-19 pandemic. Drawing on historical and contemporary controlled human infection studies, Andrews suggests that viruses do not spread as traditionally believed and criticizes the reliance on PCR tests for diagnosing viral infections. He also questions the role of global institutions in shaping scientific narratives, proposing that environmental factors and industrial toxins may play a more significant role in disease than viruses.

  • Joseph Hickey: “Is Canada Warming?” | Tom Nelson Pod #372
    Feb 14 2026

    Joseph Hickey from CORRELATION Research in the Public Interest discusses findings on Canada’s temperature records, revealing a unique stepwise increase in 1998 that accounts for all the country’s warming since 1948. This anomaly challenges the prevailing CO2-driven warming paradigm, suggesting potential influences from natural climate variability, such as ocean oscillations. Hickey also highlights issues of data adjustments and inconsistencies in Environment Canada’s records.

  • Cohler/Soon: “Rebuttal to Nikolov on global temperature” | Tom Nelson Pod #371
    Feb 10 2026

    Jonathan Cohler and Willie Soon present a rebuttal to assertions made by Ned Nikolov about the physical meaning of global mean surface temperature (GMST). They argue that GMST is a physically meaningless statistical construct that cannot represent the Earth's thermal state or energy content due to its basis in non-equilibrium thermodynamics. They emphasize that temperature is an intensive property and its aggregation across different systems is fundamentally flawed from both mathematical and thermodynamic perspectives.

  • Ned Nikolov: “Meaning of global temperature” | Tom Nelson Pod #370
    Feb 4 2026

    Ned Nikolov discusses the physical meaning of the global mean surface temperature, addressing critiques by papers from Essex et al. (2007) and Jonathan Cohler (2025) that question its validity. Nikolov argues that these critiques misunderstand thermodynamic principles, and presents his own analysis, supported by satellite data, which shows a meaningful correlation between global mean surface temperature and energy fluxes. He emphasizes the importance of using accurate scientific principles when critiquing climate science to maintain credibility.

  • Ralph Pezzullo: “Stolen Elections” | Tom Nelson Pod #368
    Jan 27 2026

    Author Ralph Pezzullo discusses his book 'Stolen Elections' based on a five-year investigation by government whistleblowers into the manipulation of elections via compromised software developed in Venezuela. The book details how this software, allegedly used to rig elections in 72 countries, was partly responsible for suspected fraud in U.S. elections since 2008. With insights from whistleblowers, computer experts, and endorsements from figures like Elon Musk, Pezzullo emphasizes the need to revert to paper ballots and ID-based voting to restore electoral integrity.

  • Alvin Wong: Volcanic Eruptions and Extreme Weather | Tom Nelson Pod #367
    Jan 20 2026

    Alvin Wong, a researcher from the University of Hong Kong, discusses the significant yet often underestimated impact of volcanic eruptions on global weather patterns and climate change. Highlighting studies from various volcanic events, including the 1982 El Chichon and the 2021-2022 Tonga eruptions, Wong explains how volcanic materials and geothermal heat released during eruptions can alter atmospheric and oceanic systems, leading to extreme weather phenomena like heavy rainfall and altered ocean circulation. Wong calls for a greater consideration of volcanic activity in climate models to improve weather prediction and understanding of climate variability.
