Schnell and Harde: Radiative and Convective Heat-Transfer in the Atmosphere.
This study uses a specialized laboratory configuration to examine how strongly convection can influence atmospheric radiation effects and to what extent greenhouse gases are causing warming or cooling under controlled conditions. A cylindrical apparatus is used, containing a heated, blackened aluminum plate that represents the Earth’s surface. This plate can be positioned either below or…
Higgs: Warming Effect of Anthropogenic Airborne Black Carbon.
Solar control of global warming and cooling (Svensmark Theory) is supported by the similarity of two published graphs: (1) average near-surface air-temperature for the last 9,000 years (from proxies and, since 1880, NASA thermometer charts); and (2) solar-magnetic output (proxies). Graph-to-graph visual cross-matching of spikes (peaks, troughs) and of multi-century trends reveals a variable temperature…
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…
Veyres et. al: Revisiting the Carbon Cycle
The authors are critically revisiting the Carbon Cycle and find for the stock-to-outflow ratio of CO2 in the atmosphere a residence time of about five years. Accordingly, only about 5.5% of the atmospheric CO2 stock comes from fossil fuel emissions not yet absorbed by vegetation or oceans, while 94.5% originates from natural outgassing of oceans…
Coleman: Could CO2 be the Principal Cause of Global Warming?
Earth’s average annual temperature has increased by near 1.50C since the 19th century. This has been analysed principally through computer-based climate models built up from causal hypotheses. The resulting theory of anthropogenic climate change (ACC) has the central hypothesis that observed global warming is driven linearly by rising atmospheric concentrations of greenhouse gases (GHG), especially…
