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…
Müller: On the Residence Time of CO2 in the Atmosphere
The impression is gained that there is still no conclusive physical description of the global behavior of CO2 absorption/emission in the various reservoirs. There is a growing group that is convinced, the residence time of CO2 in the atmosphere is approximately 4 years. Another group assumes a significantly longer residence time of 30 years or…
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…
