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.

Nikkiso Signs Agreement With Maran Tankers Management to Provide Aftermarket Service Support12.5.2026 15:00:00 CEST | Press release
Nikkiso Clean Energy & Industrial Gases Group (Nikkiso CE&IG) has announced today that it has signed a long-term service agreement with oil tanker shipping firm Maran Tankers Management Inc. Under the five-year agreement, Nikkiso CE&IG will deliver comprehensive global aftermarket support for Maran Tankers’ high pressure pumps, including scheduled cold end valve repairs at defined intervals. To guarantee minimal turnaround time, Nikkiso CE&IG will maintain critical inventory across its Marine Hubs worldwide, enabling cold ends to be received by vessels within days rather than the industry’s average of months. Nikkiso CE&IG will also provide technical guidance to Maran Tankers and carry out extended overhauls during scheduled dry-docking periods. Sean Fanniff, President of Nikkiso CE&IG’s Cryogenic Services Business Unit, said: “With Marine Hubs across Southeast Asia, Europe, the Middle East, the US, and China, we can provide our clients with a coordinated global approach and seamless p
