Ollila: Radiative Forcing of Water Vapour
The positive feedback of water vapour has been the basic feature of General Circulation Models (GCMs), which approximately doubles the warming impacts of any other climate drivers. Some published scientific papers have shown that simple climate models without this feature can simulate the temperatures of the 2000s very well. On the other hand, the observed
Veyres et. al: Revisiting the Carbon Cycle
The authors are critically revisiting the Carbon Cycle and find for the stock-to-outflow ratio of CO2 in the atmosphere a residence time of about five years. Accordingly, only about 5.5% of the atmospheric CO2 stock comes from fossil fuel emissions not yet absorbed by vegetation or oceans, while 94.5% originates from natural outgassing of oceans
Coleman: Could CO2 be the Principal Cause of Global Warming?
Earth’s average annual temperature has increased by near 1.50C since the 19th century. This has been analysed principally through computer-based climate models built up from causal hypotheses. The resulting theory of anthropogenic climate change (ACC) has the central hypothesis that observed global warming is driven linearly by rising atmospheric concentrations of greenhouse gases (GHG), especially
Schrijver: Historical CO₂ Levels in Periods of Global Greening
The increased atmospheric CO₂ level is widely recognized as a primary driver of global greening (a 30% increase in GPP since 1900). It raises the question whether such an increased CO₂ level is also a necessary condition for a large GPP. This paper evaluates whether CO₂ levels during historical periods of similar or more greenness
Huijser: Global Warming and the “impossible” Radiation Imbalance
Any perturbation in the radiative balance at the top of the atmosphere (TOA) that induces a net energy flux into- or out of Earth’s thermal system will result in a surface temperature response Correspondence: until a new equilibrium is reached. According to the Anthropogenic Global Warming (AGW)hypothesis which attributes global warming solely to rising concentrations
Grabyan: Global Atmospheric CO2 Lags Temperature by 150 yr between 1 and 1850 AD
This study investigates whether atmospheric CO₂ precedes or lags global temperature changes over the past 2000 yr, using both visual and statistical analyses. A parallel evaluation of Total Solar Irradiance (TSI) and temperature was conducted to assess the influence of solar forcing on climate variability. Temperature, CO₂, and TSI data were drawn from many well-established
Harde and Schnell: The Negative Greenhouse Effect – Part II
For our studies of the greenhouse gas emission – different to a simpler experimental set-up with a horizontally positioned Styrofoam box described in Part I – here we use an arrangement consisting of a vertically placed cylinder with uniformly heated walls and an opening at the bottom, which is sealed by an infrared-transparent foil. Below
Schnell and Harde: The Negative Greenhouse Effect – Part I
In two consecutive studies, the suitability of different experimental set-ups for detecting and measuring the emission of infrared-active gases is investigated, as this is of particular importance for understanding the atmospheric greenhouse effect. The first part presents a horizontally arranged Styrofoam box, as described occasionally in the literature for such experiments. The gases are slightly
Scafetta: Planetary Synchronization
The complex planetary synchronization structure of the solar system, which since Pythagoras of Samos (ca. 570–495 BC) is known as the music of the spheres, is briefly reviewed from the Renaissance up to contemporary research. Copernicus’ heliocentric model from 1543 suggested that the planets of our solar system form a kind of mutually ordered and
Tattersall: Planetary Resonance
Observations of solar and planetary orbits, rotations, and diameters show that these attributes are related by simple ratios. The forces of gravity and magnetism and the principles of energy conservation, entropy, power laws, and the log-normal distribution which are evident are discussed in relation to planetary distribution with respect to time in the solar system.
