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.

Cities Integrating AI Into Public Services With No Common Framework for Assessing Readiness, Oxford Insights Finds6.10.2026 04:00:00 CEST | Press release
Organisation behind the Government AI Readiness Index proposes a City AI Readiness Index, based on a new study of Abu Dhabi Cities are integrating artificial intelligence into public services and operations with no shared framework for measuring or comparing how prepared they are to do so safely, effectively or accountably. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20261005281462/en/ Cover of Oxford Insights' latest report on City AI Readiness. (Graphic: AETOSWire) Existing global indices compare countries on legislation, investment and research output, but the AI efforts happening at city level – the level of government where the technology most directly shapes daily life – are not systematically captured. To start closing that gap, Oxford Insights researchers studied AI readiness across six cities. They found that all share the same core priorities, from governance and funding to talent and infrastructure, but take dist
NEG Develops “BDX-3,” a New Starveil™ Ultra-thin Cover Glass for a Wider Range of Space Environments6.10.2026 03:00:00 CEST | Press release
Nippon Electric Glass Co., Ltd. (NEG) (TOKYO: 5214) has developed “BDX-3,” a new Starveil™ ultra-thin cover glass for space applications. BDX-3 is designed to reduce radiation-induced discoloration while providing greater ultraviolet (UV) shielding performance than BDX-2. While primarily intended for low Earth orbit (LEO), it can also be used in medium Earth orbit (MEO) and high Earth orbit, making it suitable for a wider range of space environments. Samples are now available for purchase, and NEG aims to achieve commercial adoption of BDX-3 in satellites and other spaceborne equipment. About BDX-3 Satellites and other equipment operating in space are exposed to intense UV radiation and other forms of radiation. Low Earth orbit is widely used for Earth observation and communications, medium Earth orbit for positioning systems, and high Earth orbit for communications and weather observation. Cover glass used in these environments must not only protect precision equipment from harsh cond
