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.…
In March 2023, with the publication of the so-called Synthesis report, the IPCC completed its Sixth Assessment cycle. During this cycle, which started in 2015, the IPCC published three special reports: Global Warming of 1.5 °C in October 2018; Climate…
Gratefully acknowledging the initiative of the Czech CLINTEL Working Group, I decided to present a collection of Hungarian and Hungary-related results that explicitly or implicitly address any of the five topics of the conference “Climate change, facts and myths in…
A common myth is that the fossil fuel combustion (with only minor amount of fossil carbon liberated by cement- and lime production) liberated such amounts of carbon which had been deposited for tens of millions of years. However, this is…
International Scientific Conference in Prague, November 12 and 13, 2024
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…
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 white paint or white plastic of the housings of weather stations ages, which leads to increased absorption of solar radiation and to increased temperature measurements. This alone would be a small error. However, many different state-of-the-art homogenization algorithms repeatedly…
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…
For many years, the scientific debate about the threat of rising global temperatures caused by rising atmospheric carbon dioxide concentration has depended on estimation, homogenization, the use of anomalies rather than actuals, and complex computer modelling of key variables. This…
