Ollila: Radiative Forcing of Water Vapour and its Use in Climate Models
Corrigendum In Ollila (2025) there is a spelling error in the manuscript. Equation (2) in the corrected form is:RF = -60.01 +18.435 * ln(HTPW) [Wm-2]This error has had no impact on the results since the right form of equation (2) has been applied in the calculations. Continue reading …
Cohler et. al: Earth Energy Imbalance Assessment
Global ocean heat content (OHC) anomalies and derived Earth Energy Imbalance (EEI) estimates, central to contemporary climate assessments including IPCC AR6, are constructed through processes that violate the scientific method. These metrics rely almost exclusively on temperature data from the Argo profiling float array. Their validity and reliability hinge on several critical but herein refuted
Ato: Rejection of Man-made Positive Feedback
The anthropogenic theory of global warming advocated by the IPCC is based on the theory that increased atmospheric carbon dioxide (CO2) from anthropogenic emissions causes warming, which in turn increases water vapor, triggering a positive feedback loop that leads to further warming and CO2 rise. This study examines the validity of this theory using the
Hatton: Is a 1.1°C Rise in a Century Unusual?
Much public discourse in global warming centres around the oft-quoted rise in temperature of approximately 1.1°C in global average temperature in the post-industrial period. This is considered in some quarters to constitute a “Climate Emergency” demanding “Climate Action”. In this paper we first dissect the background behind this number and what it means. Second, we
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
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
