The greenhouse effect, according to the IPCC, is due to the longwave absorption of 156 Wm-2 by greenhouse gases and partly by clouds. This absorption flux should be able to reradiate back to the Earth 346 Wm-2 , which is impossible according to the energy conservation laws of physics. The overall effect of greenhouse gases is about 50% lower than the prevailing theory.
Other energy sources beside longwave radiation absorption are shortwave radiation absorption by the greenhouse gases and latent and sensible heating. Together, these four energy sources perfectly explain the reradiation flux by the atmosphere on the Earth’s surface. The total absorption contribution of 2.4 °C by carbon dioxide (CO2 ) of 400 ppm means that the carbon dioxide warming effect of the IPCC’s calculations is about 200% too high.
“The portions of individual contributors are: water 45.6%, latent heating 30.8%, sensible heating 8.2%, carbon dioxide 7.3%, ozone 6.1%, clouds 0.9%, methane & nitrogen oxide 0.7% and aerosols 0.3%. The cloud effect is minimal, and it differs from other earlier studies (19% and 39%) because these studies do not consider the reduction of solar insolation by clouds,” said Ollila.
The reproduction of the radiative forcing by CO2 gave a 41.6% lower value for 560 ppm than the same of the IPCC. The radiative forcing values are transformed into warming values by the climate sensitivity parameter (CSP). The CSP value of the IPCC is 0.5 K/(Wm-2 ), which includes so-called positive water feedback, and which doubles the warming effects of greenhouse gases. According to this study, the CSP value is 0.27 K/(Wm-2 ). The direct humidity and temperature observations confirm that there is no positive water feedback in the atmosphere,” said Ollila.
“The warming effect of CO2 , according to the radiative forcing equation and the CSP value of this study, can be nicely fitted into the overall greenhouse effect of CO2 , but it is not the case in the simple model of the IPCC,” said Ollila.

Study: Heatwaves Increase Cough Urge, Which Salt Aerosols Reduce15.9.2026 15:15:00 CEST | Press release
New Study Indicates Non-Pharmacological Aerosol May Provide Therapeutic Relief for Respiratory Conditions Provoked by the Atmospheric Aridity Inherent to Heatwaves SC Therapeutics, with University North Carolina, Imperial College London, and Boston University, announced publication on Tuesday in Nature Scientific Reports of results from a multi-institutional study indicating that the aridity inherent in heatwaves increases cough hypersensitivity in human airways by collapsing mucus onto cilia in a manner common to chronic respiratory diseases, such as cystic fibrosis, and asthma. The researchers find that alkaline aerosols of magnesium salts reverse mucosal collapse for several hours, and reduce cough hypersensitivity as reflected in placebo-adjusted suppression of daily cough bout rate (59%, p=0.03) and persistence of suppression post treatment for 1 to 3 weeks in a randomized, double-blind, placebo-controlled study of 10 refractory chronic cough patients. “Paris recorded 5,764 excess
ADM’s Fourth Annual Regenerative Agriculture Report Highlights Growing Resilience Across the Food System15.9.2026 15:00:00 CEST | Press release
2025 programs engaged more than 56,000 farmers across 4.6 million acres in 11 countries ADM (NYSE: ADM), a global leader in innovative solutions from nature, today released its fourth annual regenerative agriculture report, showing how its programs are supporting farmers, strengthening agricultural supply chains and delivering measurable environmental outcomes around the world. “Resilience starts on the farm. By improving and protecting soil health, farmers can be better equipped to adapt to changing conditions and maintain productive operations,” said Greg Morris, SVP and President, Ag Services and Oilseeds, ADM. “That resilience can extend across the value chain, helping strengthen the food system we all depend on.” In 2025, ADM’s regenerative agriculture programs engaged more than 56,000 farmers across approximately 4.6 million acres, 11 countries and 10 crops. Compared with regional benchmarks, the programs resulted in approximately 946,000 metric tons of CO₂e reductions. “ADM view
