A Critical Reassessment of the Anthropogenic CO₂-Global Warming Hypothesis: Empirical Evidence Contradicts IPCC Models and Solar Forcing Assumptions.
Abstract
The Intergovernmental Panel on Climate Change (IPCC) attributes observed climate variability
primarily to anthropogenic CO₂ emissions, asserting that these emissions have driven approximately 1 Wm⁻² of net radiative forcing since 1750, resulting in a global temperature rise of 0.8-
1.1°C. This conclusion relies heavily on adjusted datasets and outputs from global climate models
(GCMs) within the Coupled Model Intercomparison Project (CMIP) framework. However, this
study conducts a rigorous evaluation of these assertions by juxtaposing them against unadjusted
observational data and synthesizing findings from recent peer-reviewed literature. Our analysis
reveals that human CO₂ emissions, constituting a mere 4% of the annual carbon cycle, are dwarfed
by natural fluxes, with isotopic signatures and residence time data indicating negligible long-term
atmospheric retention. Moreover, individual CMIP3 (2005-2006), CMIP5 (2010-2014), and
CMIP6 (2013-2016) model runs consistently fail to replicate observed temperature trajectories
and sea ice extent trends, exhibiting correlations (R²) near zero when compared to unadjusted
records. A critical flaw emerges in the IPCC’s reliance on a single, low-variability Total Solar
Irradiance (TSI) reconstruction, despite the existence of 27 viable alternatives, where higher-variability options align closely with observed warming—itself exaggerated by data adjustments.
We conclude that the anthropogenic CO₂-Global Warming hypothesis lacks empirical substantiation, overshadowed by natural drivers such as temperature feedbacks and solar variability, necessitating a fundamental reevaluation of current climate paradigms.
