Maybe if you look at CO2 in isolation, but it's not in isolation. It's one variable in a massively complex system with many parts and interactions we don't understand let alone know how to model accurately. Clouds are a great example. We don't know how to accurately model clouds, and a 2% change in cloud cover can explain all of the recent warming. We have no idea how a change in CO2 affects clouds and other forcings.

Another thing about CO2 forcing that is little mentioned is that the relevant absorption spectra is near saturated at current CO2 levels and that the effect of additional CO2 is logarithmic meaning even a doubling of CO2 from current levels would only have only a trivial impact on CO2 forcing in isolation. The only reason why increases in CO2 has the model-predicted catastrophic effects is because of hypothetical forcings triggered by increased CO2 that are programmed into the models and have not been observed in nature much less proven.

Maybe carbon emissions are a problem, maybe they are not. I don't know. What I do know is that the confidence claimed in climate change theory by the climate "scientists" is grossly overstated, and the vested interests to keep it overstated are as big as it gets.
