These took out much of the heat from greenhouse gasses. And in my opinion you either buy the climate change models (which are very aware of aerosols), or you don't. It doesn't make sense to believe that the planet will heat up more, that it is due to humans, but aerosols are not a part of the story.
We'd already be over 2*C if not the aerosols that humans released: https://nca2018.globalchange.gov/img/figure/figure2_1.png

We're not as screwed as many people think.
