Its kinda a natural phenomena around there.
Blasphimer. It’s SUV caused Global warming. Get your mind right citizen.
There are WOODCUTS of that haze I remember seeing. But all the descriptions from the Spanish Missions 300 years ago don’t count. Because...LIBERALS!
In modern times, it is being driven by the California Environmental Quality Act, which was signed into law by Ronnie Raygun in 1970. Because CA preceded the feds in regulating air quality, CA is the only state that can set higher standards than the feds.
I have some first hand experience with "smog" regs in the LA area, from those days. I worked in an industry that emitted a lot of VOCs, which react with NOx, in the presence of sunlight(photochemical), to create smog/ozone.
As for CO2, there was a temporary dispute between GW Bush and CA as to whether or not CA had the authority to set higher standards than the feds on CO2 since CO2 was not a traditional pollutant.
