[Ozone] An Even More Inconvenient Truth (especially for Californians)?

Ozone leads to deteriorating respiratory and cardiovascular health, which is unfortunate given that background ozone levels are rising and are expected to rise due to climate change.
EPA Ozone Standards Unhealthy for America
Ozone Responsible for More Deaths than Breast Cancer and Prostate Cancer Combined
Over Half of the US Population Lives in Areas of Excessive Ozone Concentration
6 of 10 US Cities With Highest Ozone Concentrations in California
However, it appears that ozone might even be contributing to climate change. High concentrations of ground level ozone can sicken and kill plants that would otherwise siphon carbon dioxide from the atmosphere (many of these plants are also crops). To make things worse, as the average global temperature increases, more ground level ozone forms.
Lower Crop Yields Due to Ozone a Factor in World Food Crisis
Ozone Controls Failing to Protect Human Health and the Environment
Despite increasing evidence that fossil fuels are bad all around, nothing much is being done about it.
Bill Introduced to Prohibit Federal Carbon Pollution Regulations
TL;DR: Climate change is a public health issue, too, due to air pollutants like ozone that increase in concentration at greater temperatures, and nothing much is being done about it.
Wikipedia wrote:With high confidence, Confalonieri et al. (2007) projected that climate change would increase cardio-respiratory morbidity and mortality associated with ground-level ozone.[25] Ground-level ozone is both naturally occurring and is the primary constituent of urban smog (Confalonieri et al., 2007).[42] Ozone in smog is formed through chemical reactions involving nitrogen oxides and other compounds. The reaction is a photochemical reaction, meaning that it involves electromagnetic radiation, and occurs in the presence of bright sunshine and high temperatures. Exposure to elevated concentrations of ozone is associated with increased hospital admissions for pneumonia, chronic obstructive pulmonary disease, asthma, allergic rhinitis and other respiratory diseases, and with premature mortality.
Background levels of ground-level ozone have risen since pre-industrial times because of increasing emissions of methane, carbon monoxide and nitrogen oxides (Confalonieri et al., 2007).[43] This trend is expected to continue into the mid-21st century.

Also it would have to be very precariously balanced for 2 degrees to change the chemical nature Of O3. My skepticism is high! (while superbowl).
I actually thought this was a thing we (mostly) had gotten under control.
Death by kudzu... somehow this part doesn't surprise me.
It lasts about half an hour in atmospheric conditions, possibly a bit longer here as it's not going to be especially concentrated.
Are you thinking about CFCs, which affected ozone in the upper atmosphere? I'm talking now about ozone that is specifically at ground-level.
Yup, that is what I was thinking about.
Sorry.
I mean, damn, it's air. You have to breathe it to live. You'd think people would care.

the "no true scotch man" fallacy.
But I'm not sure what type of law we can expect to deal with emissions from plants.
Rigorous Scholarship
But it appears that existing regulations aren't enough to protect people from harm, seeing as over half the US population lives in areas with excessively high ozone levels.
Also, I'm not really talking about plants, so I better remove the kudzu line from the OP.
I don't really know what effects Ozone has. I know ozonolysis can split all kinds of chemicals into even nastier chemicals, but I don't really know the health effects.
I read that when someone posted the link last week, but this is the first time I was really struck by the line
I had to stifle my laughter at work.
Which chemicals cause this (the article was unclear) and what industrial processes or products produce them? I look on my own.
So really it is regulation emissions of nitrogen oxides, carbon monoxide and 'Volatile organic compounds' which should be the focus to reduce ozone levels.
From what I can find; Styrene found in rubber, plastic, insulation, fiberglass, pipes, automobile and boat parts, food containers, and carpet backing; limonene found in makeup, medicine, solvent and renewable acetone replacement cleaners; aldehydes use in fragrances, tobacco, food products, industrial products and naturally occurring.
It seems like the key to this is full regulation of emissions of almost everything during a product's entire life-cycle. That is a serious problem as I doubt such a thing will be as "easy" to do as regulating a single obvious pollutant like carbon dioxide on a national or global scale.
