Renewables to the rescue: Beating a relentless path to clean-air’s door

It is not as if we did not already know humans are great at devising tools. We did. More of the very same as it applies to tools to determine and measure changes taking place in our atmosphere. Of this, we can be sure. Forget great, at that, we’re excellent. What we are not as … Read more

Light rail transit: Gaining on the competition

With transportation once again emitting the largest amount of greenhouse gas emissions into America’s air, it is now more important than ever to significantly reduce these and other air-pollutant emissions. In 2016 transportation-sourced emissions, for the first time since 1978, had overtaken those from the energy sector in terms of yearly output as so-reported on … Read more

California transport-sector emissions climb despite GHG’s overall decline

Once more, California’s Air Resources Board (ARB) gives the Golden State a “cleaner” bill of health. That’s fantastic news! The economy is strong, the ranks of the unemployed have dwindled and greenhouse gas (GHG) emissions are falling. From a high of 489 million metric tons of carbon dioxide equivalent (MMTCO2e) units in 2004 to 2016’s … Read more

New report stresses need to further limit soot, smog, climate pollution in America’s air

Right around this time last year, I put up the “Need to further reduce smog, soot, world-warming pollution in new report emphasized” post. Not good was the air-quality picture in the U.S. then. So, some of what I had conveyed in writing supporting that premise at that time was: “According to Environment America, people in … Read more

Progress report: California reaches 2020 GHG target of 431 MMTCO2e

“’California’s GHG emissions have followed a declining trend since 2007,’ the California Environmental Protection Agency Air Resources Board (ARB) emphasized in the Overview section of ‘California Greenhouse Gas Emissions for 2000 to 2015 – Trends of Emissions and Other Indicators,’ an adjunct or supplement to its ‘2017 Edition California GHG Emission Inventory’ document. ‘In 2015, … Read more

75 years of L.A. smog. That’s more than enough, you would think

Imagine a city, any city, having to contend with smog for three-quarters of a century. Seventy-five years; that’s a lifetime! Recognizing Los Angeles’ 75-year battle with smog is what this thread is about. How it happened On July 8, 1943, Los Angeles smog was born. The smog was so thick, in fact, that area visibility … Read more

Two regional passenger rail proposals: Some comparisons

One could argue a proposed regional passenger-rail service between the South San Joaquin Valley community of Porterville and Huron located in southwestern Fresno County, for all intents and purposes running alongside California State Route 198 or SR 198 (see: “Valley could get regional passenger rail: Tulare County Association of Governments has plan” Air Quality Matters … Read more

Satellite data show retreat of nitrates, sulfates, fine particles in California air

Regarding sulfates, nitrates, organic and elemental carbon in California air, there is good news. According to information in a Jun. 5, 2018 California Environmental Protection Agency Air Resources Board (ARB) news release, those substances in Golden State air are becoming fewer and farther between. In the “NASA satellite helps collect 15 years of Southern California air … Read more

Valley could get regional passenger rail. Tulare County Association of Governments has plan

Before the construction of California high-speed rail got underway in mid-2015, as far as I am aware, there hadn’t been a new railroad of any kind built in California’s San Joaquin Valley since the 20th century’s early days. But, if all the stars align a new, additional passenger rail service in the Valley could be … Read more

Being on ‘broad way’ maybe not such an air-smart move after all

Broadway. The term originally had to do with the former Pennsylvania Railroad’s 4-track-wide right-of-way (hence the term “broad way”) between Chicago and New York City. The term has since come to take on and be associated with a different meaning. It’s now tied in with the performing arts world. That’s enough history for right now. … Read more
