  • 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…
