This presentation and study was made in memory of Prof. Murry Salby (1951 – 2022), who in his textbook of climatology pointed out the marginal influence of humanity on the concentration of greenhouse gases in the atmosphere and who in…
Human-produced CO₂ by fossil fuel combustion, combined with the rising atmospheric CO₂ concentration and the observed temperature increase, enabled a compelling narrative to be constructed, in which these three facts, in that order, formed a chain of causality. The narrative…
Climate is changing and always has with many and varied recognised drivers. Earth‘s interaction with our celestial neighbours within the solar system and the solar systems relationships within the galaxy being perhaps the most recognised and important of these primary…
The Climate system is an extremely complex one, and it is necessary to understand its structure before analysing its dynamics and trying to make some projections of it. A key component of the Climate system is the ocean-atmosphere interface. The…
The IPCC AR6 assessment of the impacts and risks associated with projected climate changes for the 21st century is both alarming and ambiguous. According to computer projections, global surface temperature may warm from 1.3 °C to 8.0 °C by 2100,…
Advocates of non-conventional renewable energies (NCRE or renewables) claim that, by increasing electricity generation from these sources in replacement of fossil fuel-based generation, electricity prices must drop since the investment costs of these technologies have sharply dropped over the last…
This presentation was given at the Clintel Climate Conference in Prague. It was designed to be as simple as possible to describe two competing climate theories, the Radiative Transfer Concept and the Heat Transfer Concept, and that they are both…
The IPCC climate models have repeatedly shown lack of skill in reproducing observed global and regional features of Earth’s climate for the past 4 decades. These include inability to predict global patterns of warming since 1980. Thus, the IPCC models…
Over the past fifty years geophysicists have established that the planet experiences global warming and cooling episodes that are repeated about every 60 years; that these cycles are driven by decadal variations in the rate of rotation of the Earth;…
The 60-year cycle of eccentricity of Jupiter’s orbit is shown to be closely related to the 60-year cycle of Earth’s climate. Changes in Jupiter’s orbit affect the Earth’s rotation rate. The following phenomena have been shown to be related to…
We focused on geomechanics/geophysics and modelling the mechanical behaviour of the Earth’s crust (lithospheric plates). The main theme was the investigation of exogenous factors in crustal phenomena. Exogenous factors include e.g. tidal forces, cyclic changes in crustal temperature caused by…
The term “greenhouse effect” describes a crucial property of certain atmospheric gases that can absorb long-wave radiation and re-radiate it, partially back to Earth’s surface. This process keeps the surface temperature approximately 30 °C warmer than it would be otherwise.…
At the heart of Bond’s work are two important geological / geochemical processes: Continue reading …
The principal role of water and vegetation in the distribution of solar energy and in local and global climate is shown on basis of measured data. Poor knowledge of the function of plants in climate formation results in erroneous decision-making…
In climate modeling, it is generally accepted assumed that variations in the total solar irradiance (TSI) have an insignificant effect on climate, while during the Holocene the contribution of TSI to climate changes was great. Long term a weak temperature…
The recent progress with understanding a role of the solar background magnetic field in defining solar and with quantifying the observed magnitudes of magnetic field at different times activity enable reliable long-term prediction of solar activity on a millennium timescale.…
