  • Humlum: The State of the Climate 2025 Global and Arctic

    Real observations show a slight decrease of global temperature in 2025 compared with the previous ten years. Some stations in the Arctic show warming, but most are fairly stable. The Arctic Ocean is cooling to considerable depth, while the tropical and Antarctic oceans have a slight surface warming. The sea level trend is not changing…

  • Ollila: Radiative Forcing of Water Vapour and its Use in Climate Models

    Corrigendum In Ollila (2025) there is a spelling error in the manuscript. Equation (2) in the corrected form is:RF = -60.01 +18.435 * ln(HTPW) [Wm-2]This error has had no impact on the results since the right form of equation (2) has been applied in the calculations. Continue reading …

  • Cohler et. al: Earth Energy Imbalance Assessment

    Global ocean heat content (OHC) anomalies and derived Earth Energy Imbalance (EEI) estimates, central to contemporary climate assessments including IPCC AR6, are constructed through processes that violate the scientific method. These metrics rely almost exclusively on temperature data from the Argo profiling float array. Their validity and reliability hinge on several critical but herein refuted…

  • Ato: Rejection of Man-made Positive Feedback

    The anthropogenic theory of global warming advocated by the IPCC is based on the theory that increased atmospheric carbon dioxide (CO2) from anthropogenic emissions causes warming, which in turn increases water vapor, triggering a positive feedback loop that leads to further warming and CO2 rise. This study examines the validity of this theory using the…

  • Hatton: Is a 1.1°C Rise in a Century Unusual?

    Much public discourse in global warming centres around the oft-quoted rise in temperature of approximately 1.1°C in global average temperature in the post-industrial period. This is considered in some quarters to constitute a “Climate Emergency” demanding “Climate Action”. In this paper we first dissect the background behind this number and what it means. Second, we…

  • Ollila: Radiative Forcing of Water Vapour

    The positive feedback of water vapour has been the basic feature of General Circulation Models (GCMs), which approximately doubles the warming impacts of any other climate drivers. Some published scientific papers have shown that simple climate models without this feature can simulate the temperatures of the 2000s very well. On the other hand, the observed…
