Tom Nelson Ned Nikolov: “Meaning of global temperature” | Tom Nelson Pod #370
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.
