I don't see the point of trying to redefine "pollution" to include CO2. We have been discussing climate change for decades, but it was only recently that people tried to shoehorn CO2 into category of "pollution." It just takes a category where society has some consensus and then shoehorns some new disputed idea into existing category. It's an end-run around the process of building consensus around the new thing.
This is ridiculous. There is no redefinition, it was always part of definition. Seriously. The only end run around consensus are lies like "CO2 as polution is a novel thing".
In the 1990 IPCC report it talks about “greenhouse gasses” and also about “air pollution” but treats those as two distinct things: <a href="https://www.ipcc.ch/site/assets/uploads/2018/05/ipcc_90_92_assessments_far_full_report.pdf" rel="nofollow">https://www.ipcc.ch/site/assets/uploads/2018/05/ipcc_90_92_a.... For example, on page 97, it says “CO2 enrichment” may “enhance plant growth,” but that “enhanced levels of air pollution could also reduce this positive effect.” There’s it’s clearly talking about CO2 and air pollution as two different things that have opposite effects on plant growth.
CO2 can be pollution while still allowing plants to grow, plants use CO2 in their growth cycle, if you didn't know, they don't use other greenhouse gases to grow.
Page 9 lists CO2 as the first item in a list of greenhouse gases. I don't want to spend all day read this 37 year old report.
In what world are greenhouse gases not air pollutants?
Yes (I agree with you, I am just trying to rephrase to make your point even more punchy).
It has been a pollutant as soon as it has started to be emitted at large scale through combustion, in particular of fossil fuels.
People who deny it are usually very brain-washed by far-right/alt-right propaganda, which tries to hammers into their brains that "it's just the same stuff that you exhale when you breathe".
They don't understand (or rather, they haven't been told!) that the scales are incommensurate.

The thing that is also known as "air pollution"?
I want to tell you to stop being a moron, but its against this site's TOS.

Is the IPCC also “morons?”

It is only in the post-truth society of right wing anti-climate influencers that apparently someone tries to redefine the terms to exclude it.
