Errr, no. There was some cooling noted in the 20th century due to pollution, in particular from WWII when a lot of smoke and dust was injected into the atmosphere. The ramp up in industry because of the war and the prosperity afterwards only made it worse. It peaked in the late 1960s and declined afterwards due to the creation of the EPA and other organizations dedicated to pollution and particulate controls. The difference in atmospheric opacity between the 1960s and the 1980s was stark. In the 1970s you could see permanent clouds over major cities, connected by jet contrails. I remember flying out of Hobby in Houston back in the days when you used a mobile stairway on the tarmac to board. There was a noticeable bronze dome over Houston that you could see as the plane climbed.

I grew up on the Texas Gulf coast. Right smack dab in the middle of the largest petrochemical complex in the world. In the 1960s, when humidity was high, which is very often the case, you had to turn on your lights when you drove close to a refinery at times. The SOx in the air would become droplets of sulfuric acid that would eat the paint off of houses and the pantyhose off of women. They onced seined a several mile stretch of the Neches River to sample fish populations and caught one carp and one gar. The carp was dead. But that was mainly effluent from the paper mills, which made their presence known when the wind blew from the north. The menhaden processors made going to the beach pungent.
