Engelbeen, Hannon & Burton (2024) [25], hereafter EHB, is a 65-page CO2 Coalition report claiming to establish anthropogenic dominance of atmospheric CO2 . EHB’s own framing on p. 7 is that “the carbon mass balance is what definitely proves that…
Over many years there have been discussions, and also disagreement, about how well climate models can predict the future climate. The IPCC asserts that climate models are based on established physical laws along with a wealth of observations, so the…
The IPCC, NASA, NOAA, and EPA state that essentially all of the observed rise in atmospheric CO2 since the pre-industrial era originates from fossil-fuel combustion. This paper shows that claim is mathematically inconsistent with the isotopic record those same agencies…
Our approach honors the Maunder Minimum and the Modern Maximum, the two bookends, and also honors the large temperature increase of 0.75℃ between 1700 and 1950. This temperature increase is attributed to solar forcing, since greenhouse gas (GHG) concentrations are…
The United Nations Intergovernmental Panel on Climate Change (IPCC), along with its various collaborators and contributors (IPCC et al.), forecast an impending climate crisis with catastrophic consequences for the Earth’s population. They predict an alarming increase in the frequency of…
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…
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).…
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…
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)…
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…
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…
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…
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…
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…
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…
The impression is gained that there is still no conclusive physical description of the global behavior of CO2 absorption/emission in the various reservoirs. There is a growing group that is convinced, the residence time of CO2 in the atmosphere is…
