Examining the beliefs underpinning the assumption that humans are heating up the planet can be enlightening.
A book focusing on CO2 storage has recently been published by two geophysicists (Amundsen and Landro, 2023). [emphasis, links added]
Using insights from Svante Arrhenius, the late 19th-century founding “father of climate change,” the authors assess that the radiative lifetime of CO2 de-excitation in the atmosphere is about 1.1 seconds.
During this time span (1.1 seconds), an estimated 2,620 collisions with N2 and O2 molecules occur.
Nearly all – 99,998 out of every 100,000 – CO2 molecules do not radiate photons, but instead re-excite through collisions. Just two of 100,000 CO2 molecules radiate photons.
Of the CO2 molecules that absorb infrared energy from the Earth’s surface, about one of every 20 (5%) participate in the photon radiation process about 3-4 km above the surface.
So, if the CO2 concentration in the atmosphere has increased by one part in 10,000 since 1950 (0.032% to 0.042%), and even if 100% of this one-one-hundredths of a percentage point change is due to human activity, it still can be said that humans have had a vanishingly small impact on the atmospheric CO2 radiation process.

CO2 is not a contaminate or pollutant its Plant food and so all life on Earth depends upon CO2 ending or banning CO2 would bea stupid mistake based upon Politics and Junk Science
