However, the IPCC is not made up of 1 or 2 scientists - it is made up of thousands. Can they all be wrong and leftist (in Duicorps viewpoint)?
As for aerosols - all I know is when I inhale the chemicals/pollutants or use them they fill up my lungs and it is not pleasant - that's enough for me to see that they are reduced.
Also I think you are also misreading the report and nuisances of language in the report. They are reporting a similarity with the majority of aerosols and O3.

Years of examining climate change and thousands of scientists believe they have proved it! lol
