Laws of Thermodynamics Challenge Greenhouse-Gas and CLIMATE- change Hypotheses
Abstract: The greenhouse-gas hypothesis (GGH), i.e., CO2 is the cause of global warming by ~1K from ~1950-2023, is popularly believed to be established scientific truth. It is generally assumed that heat emissions from global fuel combustion are, by comparison, negligible. An application of the Hess-Gibbs 1st law of thermodynamics, however, shows that the enthalpy (H) output from yearly fossil fuel consumption is seven times greater than the H- increase of hypothetical …
