California and Other Parts of Western US Lead in Unhealthy Levels of Air Pollution

California and other parts of the western United States had the country's worst air pollution, even as air quality overall improved in the years 2019 through 2021, according to the latest report from the American Lung Association.

People of color disproportionately lived in areas with an unhealthy air quality, the report also found. They were 64% more likely than white people to live in a county with a failing grade on at least one of three measures of air quality, and 3.7 times more likely to live in a county with a failing grades on all three measures. 

That is an increase from last year’s numbers of 64% and 3.6 more likely.

The association’s 24th “State of the Air” report grades exposure to unhealthy levels of ground-level ozone air pollution, annual particle pollution, and short-term spikes in particle pollution over a three-year period.

Climate change is making the job of ensuring clean air more difficult.

"The three years covered by “State of the Air” 2023 ranked among the seven hottest years on record globally," the association said in its key findings. "High ozone days and spikes in particle pollution related to heat, drought and wildfires are putting millions of people at risk and adding challenges to the work that states and cities are doing across the nation to clean up air pollution."

As far as the western United States, more than 18 million residents live in counties with failing grades on all three measures. The 25 counties with the worst record for short-term particle pollution were all in the West.

“The good news is that ozone pollution has generally improved across the nation, thanks in large part to the success of the Clean Air Act,” said Harold Wimmer, president and CEO of the American Lung Association.

The number of people living in areas with unhealthy levels of ozone pollution or smog dropped by 19.3 million, he said.

“However, the fact is that 120 million people still live in places with unhealthy air pollution, and not all communities are seeing improvements,” he said.”

The five cities most affected by short-term particle pollution, led by Bakersfield, California, were all in the West. In all, 63.7 million people lived in counties that had unhealthy spikes in particle pollution, the most reported in the last 10 years.

Here is the complete list:

  • Bakersfield, California 
  • Fresno-Madera-Hanford, California
  • Fairbanks, Alaska
  • Visalia, California
  • Reno-Carson City-Fernley, Nevada

As for year-round particle pollution, the five worst cities also were in the West, again led by Bakersfield. A total of 18.8 people lived in a county that received a failing grade, though the good news is that overall the number dropped by 1.5 million people.

Here is the complete list:

  • Bakersfield, California
  • Visalia, California 
  • Fresno-Madera-Hanford, California 
  • Los Angeles-Long Beach, California
  • Fairbanks, Alaska

On the last measure, ozone pollution or smog, there were improvements across the country, with 19.3 million fewer people living in areas with unhealthy levels. The worst areas were once again in the West, with the Los Angeles - Long Beach metropolitan area coming in first. 

Ground-level ozone pollution can cause shortness of breath, trigger coughing and asthma attacks and may shorten life. The warmer temperatures that result from climate change make ozone more likely to form.

Here is the complete list:

  • Los Angeles-Long Beach, California
  • Visalia, California 
  • Bakersfield, California 
  • Fresno-Madera-Hanford, California  
  • Phoenix-Mesa, Arizona

Among the cleanest cities — with no days of high ozone or particle pollution and a rank in the 25 cities with the lowest year-round particle pollution levels — three metropolitan areas were in North Carolina.

The top cities were

  • Asheville-Marion-Brevard, North Carolina
  • Bangor, Maine
  • Greenville-Kinston-Washington, North Carolina
  • Lincoln-Beatrice, Nebraska
  • Rochester-Batavia-Seneca Falls, New York
  • Urban Honolulu, Hawaii
  • Wilmington, North Carolina.

CPUC Sets Schedule on AT&T Request to Relinquish ETC

CPUC Sets Schedule on AT&T Request to Relinquish ETC AT&T's California CPUC Eligible Telecommunications Carrier (ETC) designation is a complex topic with recent developments, so I'll break it down for you: Current Status: AT&T is currently an ETC in California: This means they're eligible to receive federal Lifeline support funding for providing discounted phone service to low-income residents. However, AT&T is seeking to withdraw its ETC designation: They filed a request with the CPUC in March 2023 to do so. Reasons for Withdrawal Request: Declining demand for landlines: AT&T argues that demand for traditional landline services, which are a key requirement for being a COLR, is declining rapidly. Financial burden: Maintaining landline infrastructure in rural areas is expensive, and AT&T claims it's no longer financially viable for them. CPUC's Response: Public hearings were held in October 2023: The CPUC held public hearings to g...

Walters: California's economy surges, but the future is cloudy

Walters: California's economy surges, but the future is cloudy eastbaytimes.com Walters: California’s economy surges, but the future is cloudy Dan Walters, CalMatters 4–5 minutes Last year was a strong one for California’s $3.4 trillion economy. The state added 621,400 jobs, finally regaining the nearly 3 million that were initially lost during the COVID-19 pandemic as Gov. Gavin Newsom shut down major economic sectors. The year ended with a near record-low 4.1% unemployment. “California continues leading the nation’s economy,” Newsom boasted after the December employment report was issued this month. Earlier he projected that if California were a nation, it would be close to surpassing Germany as the globe’s 4th most powerful economy. All good. In fact, some economists believe that California’s job growth is so strong that only a shortage of workers – due to a decline in the...

Japan’s Largest Helo Carrier DDH-184 JS Kaga Headed to San Diego for F-35B Testing

This Halloween, a Japanese flat-top bearing an illustrious name of one sunk at the battle of Midway may be sighted off Point Loma flying stealth jets onto North Island Naval Air Station. But this is not a ghost ship, and there is no need for San Diego's own  USS Midway to get underway. Japan's largest warship, the Izumo-class carrier JS Kaga (DDH-184), will conduct F-35B Lightning II Joint Strike Fighter developmental tests off San Diego, California from October 5 to November 18, 2023. This is part of Japan's effort to convert its two Izumo-class ships (Izumo and Kaga) from helicopter carriers to F-35B-capable aircraft carriers. Kaga has already undergone the first stage of conversion, including modifying its flight deck from a trapezoid to a rectangular shape, similar to US amphibious assault ships. The trials will help determine the optimal interior configuration for F-35B operations on these ships. Japan has ordered 42 F-35Bs, with 6 expected to be delivered by th...
