Yet another scientific study concludes CO2 is an insignificant contributor to Earth’s recent temperature changes.
New research involving a comparative analysis of satellite (CERES) observations of absorbed solar radiation (ASR) and CO2 radiative forcing modeling finds CO2 may have contributed just 0.09°C to the 0.52°C temperature increase from 2000 to 2023.
The rising ASR trend is instead the primary (0.39°C of 0.52°C) cause of the 21st century warming, and it is solely responsible for the high temperatures achieved during the second half of 2023.
Thus, it can be said that “carbon dioxide has an insignificant impact on annual and monthly temperature changes.”
What nonsense. CO2 is responsible for zilch surface warming as 99.95% of the energy absorbed by CO2 is thermalized. This is an artifact of thermal equilibrium which is textbook science and inter-alia states that at any given altitude, all molecules each have the same average temperature. CO2 is less than 0.05% of the air (420pp is less than 500 ppm) and so CO2 cannot radiate materially net of conduction to the 99% of the other atmospheric gases, 99% of which are none radiating non-GHGs.
