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.

Azalea Vision Enrolls First Patient in Proof-of-Concept Study Evaluating Novel Optical Aperture for Keratoconus and Presbyopia28.9.2026 16:27:00 CEST | Press release
Azalea Vision has enrolled the first patient in its NOA proof-of-concept study, launching the company’s clinical program. The study evaluates a Novel Optical Aperture (NOA) inside a contact lens in two patient groups, keratoconus and presbyopia. Clinical study results are expected to inform the planned first-in-human evaluation of Azalea’s fully integrated smart contact lens platform in Europe and the United States. Azalea Vision, a Belgian healthtech company building the first medical-grade smart contact lens, today announced that it has enrolled the first patient in its NOA proof-of-concept study. The study marks the start of Azalea’s clinical program, following its selection for the European Innovation Council (EIC) Accelerator. This press release features multimedia.

Xsolla Releases The Xsolla Report: Mobile D2C Edition28.9.2026 15:00:00 CEST | Press release
New Data From More Than 800 Mobile Web Shops Finds Direct-to-Consumer Has Become a Standard Operating Discipline, With Top Performers Capturing More Than Half of a Title's Revenue Regardless of Studio Size Xsolla, a global commerce company, today released The Xsolla Report: Mobile D2C Edition, a new study examining how direct-to-consumer commerce is performing across mobile games. Drawing on data from more than 800 live Xsolla Web Shops alongside public market and regulatory data, the report shows that D2C has moved past the question of whether it works and into a new phase: studios seeing the strongest results are the ones treating their Web Shop as an operating discipline rather than a one-time build. This press release features multimedia. View the full release here: https://www.businesswire.com/news/home/20260928312597/en/ Graphic: Xsolla Three themes run through the report. First, the gap between a typical Web Shop and a top-performing one is wide, and closing it has little to do

Incognito Software Systems, a leading global provider of service orchestration, device management, and network intelligence solutions, today introduced NEXA, an AI-driven network intelligence and automation platform that enables broadband service providers to turn operational data into action. NEXA unifies network, device, service, and subscriber data in a single intelligence layer, delivering real-time and predictive insights that help service providers identify issues sooner, better understand the subscriber experience, and take faster, more informed action across their operations. As service providers seek to differentiate beyond connectivity, subscriber experience has become a critical competitive advantage. However, networks have evolved into complex service platforms that span access, edge, cust
Volante Technologies and Circle advance stablecoin payment and settlement capabilities for financial institutions28.9.2026 15:00:00 CEST | Press release
Collaboration enables banks to integrate USDC workflows within existing multi-rail payments infrastructure Volante Technologies, the global leader in Payments as a Service (PaaS), today announced a strategic collaboration with Circle Internet Group, Inc. (NYSE: CRCL) (“Circle”), a leading internet financial platform company and the issuer of USDC1 through its regulated entities, to help financial institutions integrate stablecoin payment and settlement capabilities into their existing payment operations.
