The global mean surface temperature (GMST) effects of a 1 W/m² radiative forcing, or positive/negative energy imbalance, has been obtained from the observations from the 1991 Mt. Pinatubo eruption. CO2’s climate effects are claimed to be many times larger than observations indicate.

The observed climate sensitivity (CS) to a perturbation to Earth’s Energy Imbalance (EEI) is, in a new study (Pauling et al., 2023), defined as -0.4°C per -9 W/m², or 0.044°C per W/m². These values were assessed using observations from Mt. Pinatubo.

Anthropogenic global warming advocates suggest it takes an increase of 22 ppm CO2 (about 10 years) to produce a surface forcing change of 0.2 W/m² (Feldman et al., 2015).

So, using the Feldman formula, it would take 110 ppm (40-50 years) to produce a positive 1 W/m² surface forcing imbalance.

If the 0.044°C per W/m² CS to a radiative forcing is accurate, this means an accumulated +75 W/m² perturbation is ultimately required to produce the alleged GMST response (3.3°C) to a doubling of the CO2 concentration (from 280 to 560 ppm) with feedbacks.

These results are clearly not realistic.
