It seems like once pollution levels drop below California levels the interest in further reducing air pollution drops to nearly 0.

Drivers from the world’s poorest cities who keep their windows down are exposed to 80% more air pollution

https://www.greencarcongress.com/2020/0 ... kumar.html

. . . In a study published in the journal Science of the Total Environment, researchers led by Surrey’s Global Center for Clean Air Research (GCARE) investigated air pollution exposure levels for commuters in 10 different global cities: Dhaka (Bangladesh); Chennai (India); Guangzhou (China); Medellín (Colombia); São Paulo (Brazil); Cairo (Egypt); Sulaymaniyah (Iraq); Addis Ababa (Ethiopia); Blantyre (Malawi); and Dar-es-Salaam (Tanzania).

The research team investigated PM2.5 and PM10 exposure levels inside vehicles during peak hours in the morning and evening, as well as off-peak hours in the middle of the day. The scientists measured how exposure levels changed when drivers used recirculation systems, fans and simply opened the windows. . . .

Irrespective of the city and car model used, a windows-open setting showed the highest exposure, followed by fan-on and recirculation. Pollution exposure for windows-open during off-peak hours was 91% and 40% less than morning and evening peak hours, respectively. The study also found that the windows-open setting exposed car passengers to hotspots of air pollution for up to a third of the total travel length.

The study found that commuters who turn on the recirculation are exposed to around 80% less harmful particles than those who open their car windows. Car cabin filters were more effective in removing pollution than fine particles, suggesting that if new cars had more efficient filters, it could reduce the overall exposure of car commuters.

"To be blunt, we need as many cars as possible off the road, or more green vehicles to reduce air pollution exposure. This is yet a distant dream in many ODA countries. Air-conditioned cars are unattainable for many poor and vulnerable commuters across the world, but our data is clear and coherent for all 10 participating cities.

We must now work with our global partners to make sure they have the information needed to put in place programs, policies and strategies to protect the most vulnerable in our communities and find realistic solutions to these serious problems."

—Professor Prashant Kumar, Director of GCARE at the University of Surrey . . . .

I'm about 900 miles from the fires and the sun sets look like it's the end of the world. So it must really suck to be in California.

Right, California. Even as most of the lands burning are Federal, it is California's problem.

Even though most of the smoke is from Oregon, it is California's problem.

Right. Sure. When you graduate from High School and get a job, you can't post so much. I can hardly wait.

Possession is 9/10th of the law.
New mexico has some where around 13 million acres of federal land and it's not on fire like California.
I don't think the fire cares if it burns federal land.
I don't need a real job my wife is the bread winner. I just work for the insurance.
You would be surprised at the benefits part time Internet trolling provides.
