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 Launches Unified Software Platform to Support Complex Environments8.4.2026 11:00:00 CEST | Press release
Cyviz AS announces the launch of its enhanced software platform, marking a milestone in the company’s strategic transition toward becoming a technology‑ and platform‑led company. The Cyviz Software Platform helps organizations monitor, manage, and optimize complex AV and IoT environments through a single, unified software layer. Across industries such as energy, defense, transportation, consulting, and large enterprise environments, organizations increasingly rely on complex, multivendor technology ecosystems to support critical operations. These are often managed using fragmented tools, resulting in limited visibility, higher operational risk, and reactive maintenance. Cyviz’ platform addresses this challenge by unifying monitoring and management across technologies, vendors, and locations. With real-time insights, proactive alerts, and centralized control, organizations can move from reactive incident handling to more predictable and resilient operations. “Many organizations are stru

HPE Takes Licence to Patents Offered Through the Sisvel Wi-Fi Multimode Pool8.4.2026 10:00:00 CEST | Press release
Hewlett Packard Enterprise (HPE) has become the latest company to take a licence to the patents offered through the recently launched Sisvel Wi-Fi Multimode pool. It joins Sony Group Corporation, Huawei, Panasonic, Philips and ZTE as a licensee of the programme. The latter four are also licensors, along with KPN, Mitsubishi Electric, Orange, Aegis 11 SA (a Sisvel affiliate), SK Telecom and Wilus. HPE is a major presence in the global WLAN market and is a leading manufacturer of both consumer and enterprise routers. The deal with Sisvel was reached on an amicable basis. The Sisvel Wi-Fi Multimode pool is the successor programme to the Sisvel Wi-Fi 6 patent pool. Over a three-year period, this closed agreements with nearly 40 companies, including Acer, Netgear, Cisco and HP. Covering Wi-Fi 7 as well as 6, the Multimode programme offers an efficient way to access essential Wi-Fi rights for years to come. “We are delighted to welcome Hewlett Packard Enterprise as the latest licensee of the
Zyxel and Openreach Team Up to Reduce Plastic Waste in Full Fibre Installations8.4.2026 10:00:00 CEST | Press release
A new partnership between Zyxel Communications and Openreach is helping to cut plastic and packaging waste from the UK’s Full Fibre rollout - by deploying re-cycled ‘modems’ to connect customers. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260408766604/en/ Openreach - GPON ONT Zyxel is deploying a range of new Optical Network Terminals (ONTs) - the wall-mounted box of electronics that converts optical signals into electrical ones used by household devices - with re-engineered casings made from 95 per cent recycled plastic.1 Openreach engineers have already installed half a million of Zyxel’s sustainable ONTs and the network provider expects to install even more this year as customers upgrade to Full Fibre - the UK’s most reliable broadband technology. The GPON2 devices use recycled plastic in their construction and arrive in zero‑plastic minimal packaging made from recycled materials. Openreach is working with Zyxel and o
