New Study: Atmospheric CO2 Residence Time Is Only 5 Years – Too Short To ‘Affect The Climate’

Since the early 1990s the conventional assumption, aligned with modeling, has been that a molecule of human CO2 emission stays in the atmosphere – its residence time – for centuries. This fits the anthropogenic global warming (AGW) narrative. But empirical evidence contradicts these model-based assumptions. Residence time is closer to 5-10 years.
In Table 1 of a new study, Stallinga (2023) compiled a list of 36 published estimates of CO2 residence time spanning the decades 1957-1992. All of these scientists determined CO2’s atmospheric residence time is about 5 to 10 years or less.

Of course, these were the pre-IPCC decades in climate research, when “the science” was pursued independent of government interference. For example, it was still acceptable in the 1950s to early 1990s for scientists to publish actual ice core measurements showing the atmospheric CO2 content ranged up to 700 ppm, even 2,450 ppm, in the ice sheets and glaciers examined throughout the last 10,000 years (Jaworowski et al., 1992).
