Good morning, and welcome to the Essential California newsletter. It’s Tuesday, July 2, and I’m writing from Los Angeles.
Southern California and smog have long been synonymous in the cultural imagination. But for decades the region saw hard-fought improvements in air quality from its lung-choking past. Those Southern California air quality improvements were echoed across the nation, as years of emissions-cutting regulations helped everyone breathe a little easier.
But, as my colleagues Tony Barboza and Rahul Mukherjee explained in an investigation published yesterday in the Los Angeles Times, air quality across the U.S. has once again started to slip, with the worst issues seen in Southern California.
I spoke to Tony, who has spent the last five years as The Times’ air quality beat reporter, about what’s causing the decline in air quality and why it matters.
Why has air quality improvement stalled after decades?
There are a number of factors. We know that it’s getting harder to find sources of pollution to cut, and that emissions are declining more slowly. If you talk to air quality regulators, they’ll tell you that all the low-hanging fruit has been picked. We’ve already gone after the biggest sources of pollution and cut them back dramatically. But we still have a long way to go, particularly with some of the biggest polluters like diesel trucks. Another factor is unfavorable weather, which means hotter temperatures and more stagnant air in the summer, where we have days on end with little movement to disperse the pollution.
Is climate change a factor?
Yes, by raising temperatures, climate change is making air pollution harder to control. It’s speeding up the chemical reactions that form smog.

How seminal was the 1970 Clean Air Act to the decades of progress that we’ve previously seen on air pollution in California?
The 1970 Clean Air Act came at a time when air pollution was a horrendous, visceral problem in many cities across the country. Nowhere was it worse than in Los Angeles and other parts of California. That law helped usher in tough regulations that brought decades of uneven, but on the whole steady, progress toward cleaner air. We’ve been living with the benefits of that. Studies in recent years in Southern California have shown the dividends from that law, with children having measurably stronger and bigger lungs as a result of cleaner air.
The most notable setback in Southern California has been with ozone. What exactly is ozone and why is it so dangerous?
There are generally two kinds of pollution that we worry about for large metro areas like Los Angeles. There is fine particle pollution, or soot, and that tends to build up more in colder weather. And then there’s ozone — and that’s a key ingredient in the more notorious type of L.A. smog that builds up when it’s hot out.
The effect of exposure to ozone gas is a little bit like having sunburn on your lungs. We know from decades of studies that it’s harmful. Ozone is also linked to a lot of health problems, like asthma attacks and other respiratory issues that send people to the hospital and can even be deadly. Ozone is the pollutant that we’ve seen the most notable lack of progress on in recent years.
How worried should the average Southern California resident be about air quality?
Anybody who’s seen a rise in air pollution in their community should be concerned that it’s going in the wrong direction. But it’s also important to give this perspective. Compared to the 1970s or ’80s, we’re all breathing much cleaner air. What happened to L.A. smog has really been a dramatic success in the long term. The concern now is about backsliding.
Despite the long-term improvement, we still have areas like San Bernardino or Riverside where people are breathing dirtier air, and on many, many more days than people closer to the coast or in downtown L.A. There is a sharpening divide, where people inland are dealing with this problem much more day in and day out. And people along the coast might think it’s something that’s already been solved. That’s the dynamic you see emerging more strongly now.

And now, here’s what’s happening across California:

Today’s California memory comes from Jenine Baines:
“When I first visited L.A., my grandfather lived on Franklin Avenue near Capitol Records, which sent the Beatlemaniac in me into transports of joy. Equally exciting were the ‘hippies’ lining Hollywood Boulevard. Grandpa and I wore love beads too. One day, we visited the set of ‘I Dream of Jeannie.’ (We were related to Barbara Eden’s husband.) Everyone was very nice, but Dr. Bellows kissed my hand! After finishing the day with hot fudge sundaes at the Brown Derby on Hollywood and Vine, I never wanted to leave. Fourteen years later, Major Nelson was J.R. Ewing, and I returned for good.”
