The present issue 6.1 covers publications accepted during the first half of 2026. It contains five research articles, two essays, one invited address and one corrigendum. The contributions address a broad range of subjects, including paleoclimatic temperature variability, the statistical…
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).…
It is a simple and seductive argument: (1) we are burning fossil fuels and emitting CO 2 into the atmosphere; (2) CO2 is a greenhouse gas; (3) the amount of CO2 in the atmosphere is increasing; (4) the world is…
Professor Kvalheim, Distinguished Audience, Ladies and Gentlemen, many thanks for bringing me to Norway. As the recently appointed second president of Clintel, I have received several invitations from Clintel supporters in foreign countries, but yours is the first I have…
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…
