New Study Highlights Major Flaws in IPCC Climate Models

A groundbreaking study has exposed significant flaws in the climate models used by the Intergovernmental Panel on Climate Change (IPCC), raising serious questions about their reliability. The research reveals that the IPCC's models, designed to attribute climate change primarily to human activities, have consistently overestimated temperature increases. Specifically, these models overestimated warming by 1.8°C to 2.5°C between 1970 and 2019. The study further highlights that even a basic benchmark model, which simply projects future temperatures based on historical averages, outperformed the IPCC's complex models by a factor of 16 from 2000 to 2019. This stark contrast underscores the lack of predictive validity in the IPCC's approach. In contrast, models that incorporate Total Solar Irradiance (TSI) as a key factor demonstrated greater accuracy, with much smaller error margins. The authors argue that the IPCC's reliance on flawed models undermines their use in shaping climate policies, suggesting that the errors are so substantial they render the models practically irrelevant for policy-making. This study calls for a reevaluation of the IPCC's methodologies and a closer examination of alternative factors influencing climate change, emphasizing the need for more reliable and transparent research to inform global climate strategies.
