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.

Integrated Hubs for Green Chemistry Research Aim to Transform How Chemicals and Materials Are Designed12.11.2026 17:00:00 CET | Press release
International network will investigate fundamental principles for creating safer, higher-performing chemicals and materials The Gordon and Betty Moore Foundation today announced four Integrated Research Hubs to explore new frontiers in chemical design, from materials that respond to their surroundings to molecules designed for safety from the start. Bringing together global researchers across institutions and disciplines, the hubs will investigate fundamental principles that could enable new capabilities in chemicals and materials while improving performance and protecting human health and the environment. The research priorities emerged through extensive engagement with the scientific community to identify the questions that could transform what chemistry can achieve. Each hub will connect researchers across institutions around one of four green chemistry focus areas: Safer molecular design: Led by The George Washington University, this hub will combine artificial intelligence and qua

Tigo Energy and Google Cloud Pair AI-Powered Tools for Solar Installers and Utilities12.11.2026 15:00:00 CET | Press release
The collaboration combines Tigo software with Google’s Gemini models on Google Cloud to help automate installer and utility operations for distributed energy portfolios. Tigo Energy, Inc. (NASDAQ: TYGO) (“Tigo” or “Company”), a leading provider of intelligent solar and energy software solutions, today announced a collaboration with Google Cloud to develop AI-enabled operational workflows for solar installers and distributed energy portfolios. By making core Tigo data and software products available through Google Cloud, Tigo aims to deliver faster deployment, simplified data integration, and additional insights with Gemini. The resulting workflows will help installers, asset managers, and energy operators more easily identify issues, prioritize actions, and automate routine operational tasks across growing fleets of distributed energy systems. As solar and storage portfolios expand, energy businesses are increasingly responsible for managing more sites, more system data, and more custo
Patsnap Releases State of Pharma Intelligence 2026 Report, Reveals Pharma's Cautious Embrace of AI in Decision-Making12.11.2026 15:00:00 CET | Press release
A new survey of 130 senior life sciences leaders on AI in pharma R&D and competitive intelligence finds that 92% can name a recent R&D, portfolio, or partnership decision where AI changed the outcome. Patsnap, the AI-native innovation intelligence company for IP and R&D teams, today released "State of Pharma Intelligence 2026: The Confidence to Act", a benchmark report on how pharma teams use and trust AI in R&D, competitive intelligence and business development decisions. The report draws on responses from 130 senior leaders at Director level or above across the United States, the United Kingdom, Germany, Switzerland, and France, spanning drug developers, CDMOs/CMOs, CROs, and consulting and professional services firms. The survey was fielded in August 2026 in partnership with NewtonX. Patsnap commissioned the research to understand how AI is influencing decisions across pharma R&D and business development, what builds confidence in its output, and where intelligence workflows fall sh
