That could change; Monday in Fresno is forecasted to be 91 degrees. Parents picking up their children from schools in air-conditioned automobiles are … Read more
Fortunately, the news is mostly good: Greenhouse gas emissions in California fell. Transportation is one trouble spot, however – the main one. Speaking directly to this, on Aug. 12, 2019, the California Environmental Protection Agency Air Resources Board (ARB) released its California Greenhouse Gas Emissions for 2000 to 2017: Trends of Emissions and Other Indicators … Read more
For the longest time, it has seemed like, air pollution and emissions of greenhouse gases were thought of in different contexts.

The sky is the limit. That these are used in the railway realm is nothing new. What is new, on the other hand, is the way in … Read more
To recirculate or not is the question. There has been some discussion in the news as of late about the riding environment inside the automobile and how placing the atmospheric control to the “recirculate” setting, can result in marked improvement in interior air quality (when windows are in the fully closed position) compared to switching … Read more
Every now and then, the air-quality value of bicycle versus car commuting is called into question. Such is the case in today’s thread. In fact, the California Environmental Protection Agency Air Resources Board (ARB) in its “Study: Commuters’ exposures to air pollution greatly depends on mode of travel: Sacramento area study shows light rail commuters … Read more
The way in which one commutes can make a real difference in terms of what one’s exposure to in-transit or during-the-commute pollution is. A related study conducted in Sacramento, California recently has been undertaken in order to learn more. On this, the California Environmental Protection Agency Air Resources Board (ARB) in its “Study: Commuters’ exposures … Read more

Heat as high as that becomes more than a bit uncomfortable and gets old rather fast the longer those triple-digit temperatures hang around. When that happens, talk about such in these here parts seems … Read more
