In a collection of research papers devoted to the problem of solar variability and its origin in planetary beat, it is demonstrated that the forcing function originates from gravitational and inertial effects on the Sun from the planets and their…
On 7 January, 2014 at 18:32 GMT, the Sun unleashed a massive X1.2-class solar flare, seventimes the size of the Earth (NASA News, 2014b). At the occasion there was a strict triple inferior conjunction of Jupiter, Earth and Venus with…
Herein I discuss common errors in applying regression models and wavelet filters used to analyze geophysical signals. I demonstrate that: (1) multidecadal natural oscillations (e.g. the quasi 60 yr Multidecadal Atlantic Oscillation (AMO), North Atlantic Oscillation (NAO) and Pacific Decadal Oscillation…
Close examination of the small perturbations within the atmospheric CO2 trend, as measured at Mauna Loa, reveals a strong correlation with variations in sea surface temperatures (SSTs), most notably with those in the tropics. The temperature-dependent process of CO2 degassing…
Effect of Variable Choice on Reliability and Predictive Validity For a model to be useful for policy decisions, statistical fit is insufficient. Evidence that the model provides out-of-estimation-sample forecasts that are more accurate and reliable than those from plausible alternative…
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…
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…
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,…
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…
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.…
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 …
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…
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…
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 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…
In this study we investigate the impact of greening on the Earth in terms of gross primary production (GPP) on the natural atmospheric CO₂ level. The total mass of CO₂ in the atmosphere is equal to the yearly amount of…
