Ato: Pitfalls in Global Warming and Climate Change Research
Recent global warming and climate change studies frequently assume that the rise in atmospheric CO2 is entirely due to human emissions. In particular, the assumption is based on a figure of CO2 concentration of 280 ppm at the end of the pre-industrial period. However, this assumption reveals itself to be contradicted by an examination of…
W. A. van Wijngaarden and W. Happer: Radiation Transport in Clouds
We briefly review the dominant role of clouds in Earth’s climate. The earliest observational studies of heat transfer through Earth’s atmosphere, for example, those of John Leslie around 1800, showed that clouds have a large effect on radiative heat transfer from Earth’s surface to space. Greenhouse gases also affect heat transfer, but much less than…
Aaslid: Climate Science versus Politics
Starting with a critical look at the IPCC science, from the excellent First Assessment Report in 1990 and downhill to the latest Sixth Assessment Report with its claim that we have had no natural climate change since the pre-industrial era, we also take a closer look at the 2010 IAC critical evaluation of IPCC, as…
Cederlöf: The Temperature Fluctuations in Uppsala has Natural Causes
The temperature record from Uppsala in Sweden starts already in 1722. This is one of the world’s longest temperature series available. A great job has been made to adjust and homogenize this data to be consistent over time, measurement locations and changed equipment. However, during the 20th and 21th century this temperature series has diverged…
Solheim: SCC – the three first years
The scientific journal Science of Climate Change was initiated by the Climate Realists in Norway in the summer of 2020. The first issue appeared in August 2021 and the journal has now existed in 3 years and produced 11 issues. The objective of this journal was and is, to publish – different to many other…
Hansen: The Danish Energy Transition
Denmark has set ambitious goals for CO₂-emission reductions and wishes to play the role of front-runner in the World. However, in reality the results are not so impressive and the transition is running into serious difficulties. Continue reading …
Brekkestø: The Rise and Fall of Civilizations in a Climate Perspective
Civilizations flourished during the warm periods, such as the Bronze Age, the Roman era, and the medieval times, when weather conditions were relatively stable with more precipitation in the tropic and subtropical areas. Civilizations experienced decline or succumbed during the cold periods, such as 1 200 to 500 BC, 300 to 700 AD and the…
Koutsoyiannis: Relative importance of carbon dioxide and water in the greenhouse effect
Using a detailed atmospheric radiative transfer model, we derive macroscopic relationships of downwelling and outgoing longwave radiation which enable determining the partial derivatives thereof with respect to the explanatory variables that represent the greenhouse gases. We validate these macroscopic relationships using empirical formulae based on downwelling radiation data, commonly used in hydrology, and satellite data…
Ato: Multivariate Analysis Rejects the Theory of Human-caused Atmospheric Carbon Dioxide Increase.
The impact of certain factors on the changes in atmospheric carbon dioxide (CO₂) concentrations has yet to be elucidated. In particular, the impacts of sea surface temperature (SST) on the balance of CO₂ emissions and absorption in the atmosphere and the human use of fossil fuels have not been rigorously compared. In this study, the…
Ad Huijser: Greenhouse Feedbacks are Intrinsic Properties of the Planck Feedback Parameter
The idea that our climate reacts differently to anthropogenic forcings than to natural instabilities through the phenomenon of “feedbacks”, seems widespread. This paper shows that climate feedbacks are not effects induced by forcings, but in fact “constitute” our climate. Independent from the origin of a disturbance, our climate will always respond according to the Planck…
