Debunking the Latest CO2 "Saturation" Paper
A paper published earlier this year is the latest in the long history of attempts to show that CO2 is already "saturated" in the atmosphere, and therefore increased CO2 cannot cause any more warming. Kubicki et al 2024[1] attempts to make this point by modeling the atmosphere in a couple different experiments. The result of their experiments suggested to them that we should question whether "additionally emitted CO2 in the atmosphere is indeed a greenhouse gas," since their experimental results, "unequivocally suggests that the officially presented impact of anthropogenic CO2 increase on Earth's climate is merely a hypothesis rather than a substantiated fact." But de their experiments actually justify this claim? The Greenhouse Effect In order to see if their experiment indeed challenges accepted science regarding the Greenhouse affect, we should first explain how increasing CO2 is expected to cause an increase in GMST - that is, we need to understand
