Falling levels of air pollution drove decline in California’s tule fog

The below Apr. 10, 2019 press release is from University of California at Berkeley. The Central Valley’s heavy wintertime tule fog – known for snarling traffic and closing schools — has been on the decline over the past 30 years, and falling levels of air pollution are the cause, says a new study by scientists … Read more

San Joaquin Valley air quality explained – by the numbers

According to information in an Apr. 11, 2019 press release, the American Lung Association is soon to publicly release its much anticipated 2019 State of the Air report that, presumably, will once again confirm what many already know: that California’s San Joaquin Valley has America’s worst air quality where fine particulate matter pollution is concerned … Read more

Carbon-capture technology: An effective means to control climate?

Giant fans put in position, the flow of air through which would allow for the separating out of carbon from it. That carbon, in turn, through a number of intermediate processes, steps, to be converted into fuel for use in aircraft, automobiles, ocean-going vessels and trucks. An absurd notion? Apparently not. In a New York … Read more

A missed opportunity light rail and/or streetcar transit need not be

What appears to get their gooses more than anything else is the thought of unsightly overhead catenary wire (the electrical distribution system for powering such networks – hint: there are some that operate catenary-free … Read more

To stop continued tainting of central Ariz., northern Cal. air, groups call on court

Environmental change: Implications for humans going forward

In the mid-1980s when I was doing Master’s thesis work, I obtained a Cal Poly college catalog for the years 1984-’86. My research was all about the program I enrolled in when I attended said university located in San Luis Obispo in California, between Sept. 1973 and Mar. 1976 – Engineering Technology. Interestingly, and quite … Read more

At long last, a curbing-air-pollutant-emissions-and-greenhouse-gases focus

For the longest time, it has seemed like, air pollution and emissions of greenhouse gases were thought of in different contexts. Air pollution is thought of as being associated with poisons (toxic chemicals, toxicants or chemical pollutants) and haze in – or discoloration of – the air and poor – and damage to – health, hospitalizations and … Read more

No place like home for the holidays – ’tis the season

As to how many Americans have traveled, are or will be traveling throughout the holiday and dare I call it the end-of-year crush, I haven’t a clue. I’ve heard reports – I mean, who hasn’t? One-hundred-million; 105 million; 110 million; a-hundred-fifteen million, really it’s anyone’s guess. So, picture if you can 110 million traveling Americans. … Read more
