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.

Cyviz: Microsoft’s Immersive Approach to Collaboration12.6.2026 09:00:00 CEST | Press release
At Microsoft’s Innovation Hub in Amsterdam, immersive technology is used to enable co-creation rather than one-way presentations. In the company’s Immersive Suite, customers, data experts, and technology specialists come together in a shared environment to address complex challenges more effectively. Watch Video Case Study >> This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260612831180/en/ Watch Video Case Study >> https://www.cyviz.com/case-studies/microsoft-immersive-suite/ As business and technology environments grow more complex, establishing shared understanding across disciplines has become critical. The Immersive Suite is designed for active collaboration, where visual narratives, data, and technical content are explored interactively. This allows participants to test scenarios, align perspectives, and move more efficiently from discussion to decision. “We deliberately work with familiar tools like PowerPoint. That all
LTM Launches AI 1000 to Develop the Next Generation of Forward Deployed Engineers12.6.2026 08:14:00 CEST | Press release
LTM, the Business Creativity partner to the world’s largest enterprises, today announced AI 1000, a strategic workforce transformation initiative anchored by a dedicated Center of Excellence (CoE). The program will develop a pool of 1,000+ AI-certified engineers, including Forward Deployed Engineers (FDEs), to help enterprises adopt, deploy, and scale AI. The launch comes amid a major shift in enterprise tech talent. The FDE — among the fastest-growing roles in the AI ecosystem — combines the technical knowledge of LLMs and domain SLMs with business understanding to turn ideas into quantifiable ROI accretive outcomes and to drive client adoption. AI 1000 is LTM’s structured response to this shift: it provides the training, platforms, and governed career frameworks to develop FDEs at scale. AI 1000 takes an end-to-end approach to talent development via a four-stage model: Identify, Enable, Deploy, and Govern. It starts by identifying high-potential engineers using a proprietary AI Readi
