Physicists: Increasing CO2 By 100% Only Reduces Radiative Cooling To Space By An Imperceptible 1%
By Kenneth Richard on 9. January 2025
“An increase in low cloud cover of only about 1% could largely compensate for the doubling of CO2.” – van Wijngaarden & Happer, 2025
Ph.D physicists detail just how insignificant CO2 is as a factor in climate change, revealing that doubling the CO2 concentration from 400 ppm to 800 ppm – a 100% increase – hypothetically reduces radiative heat loss to space by just 1%.
Since CO2 has only risen by 50% since 1750 (280 ppm to 420 ppm), CO2’s total greenhouse effect influence in reducing outgoing radiation has thus far been in the range of tenths of a percentage point. A less than 1% change in outgoing radiation over hundreds of years is not even detectable amid the noise of outgoing radiation measurement. Observation error in measuring Earth’s outgoing radiation is 33 W/m², for example.
