A correlation is found between changes in Earth’s length of day [LOD] and the spatio–temporal disposition of the planetary masses in the solar system, characterised by the z axis displacement of the centre of mass of the solar system [CMSS]…
A Venus–Earth–Jupiter spin–orbit coupling model is constructed from a combination of the Venus– Earth–Jupiter tidal-torquing model and the gear effect. The new model produces net tangen-tial torques that act upon the outer convective layers of the Sun with periodicities that…
Commensurabilities are calculated based on published orbital periods of planets and satellites. Examples are given for commensurabilities that are strong or very strong. There are sets of com-mensurabilities that involve 3–4 celestial bodies. Our moon–Earth system is probably a key…
Reconstructions of solar–terrestrial (ST) phenomena, in sufficient quality, several thousands of years backward by means of radiocarbon (14C), 10Be or 18O isotopes have been employed for study of possible responses of the ordered (trefoil) and disordered intervals (types) of the…
Herein we adopt a multiscale dynamical spectral analysis technique to compare and study the dynamical evolution of the harmonic components of the overlapping ACRIMSAT/ACRIM3 (Active Cavity Radiometer Irradiance Monitor Satellite/Active Cavity Radiometer Irradiance Monitor 3), SOHO/VIRGO (Solar and Heliopheric Observatory/Variability…
The Schwabe frequency band of the sunspot record since 1700 has an average period of 11.06 years and contains four major cycles, with periods of 9.97, 10.66, 11.01 and 11.83 years. Analysis of the O-C residuals of the timing of…
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…
The Intergovernmental Panel on Climate Change (IPCC) attributes observed climate variability primarily to anthropogenic CO₂ emissions. This conclusion relies heavily on adjusted datasets and outputs from global climate models (GCMs) within the Coupled Model Intercomparison Project (CMIP) framework. However, this…
A study published by the CO2 Coalition claims that the rise in atmospheric CO2 concentration is manmade. This claim is examined here and rejected. There are two fundamental shortcomings in the study: It is based on an inappropriate model, that…
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…
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…
