Discourse for all interested in all things air-quality related
We’ve been told lots about greenhouse gases (GHGs) and what effect these have on atmospheric warming and climate. They are therefore grouped or classified thusly as: climate pollutants. But, the climate-pollutant class is not limited to greenhouse gases alone. Black carbon (also known as elemental carbon) is an element under that umbrella as well. Carbon … Read more

Here’s the deal: Based on the myriad observations made and pertinent data gathered by scientists (many of whom are world-renowned, by the way) over the years supporting, with a high degree of confidence, the premise that the earth risks going off the edge climatologically speaking if we don’t get off the human-induced greenhouse gas-emitting track … Read more
These days, there isn’t a day that goes by that I don’t notice (witnessing first-hand, seeing or hearing, watching on television) something having to do with air pollution. It figures, doesn’t it?! Just this past Sun., Feb. 5, 2023, in fact, a related story was included in CBS’ “Sunday Morning” lineup. The segment mostly had … Read more

Okay, so the other day, I was reading this article* and contained in it I discovered a reference having to do with an equivalency, in this case methane escaping or leaking from gas stoves and how that could equate to carbon dioxide emanating from the exhaust pipes of automobiles whose engines operate on the principle … Read more
Ever since the big-smog episodes of the mid-1900s – these encounters really opening our eyes to the harm to health that this type of pollution can cause – there has been much progress made in the areas of identifying the key ingredients that enable smog formation – like hydrocarbons, oxides of nitrogen and heat from … Read more
When the interested Conference of the Parties (COP) attendees head off to these annual global climate-change networking summits, they, for the most part, I would think, have open minds, their hoping, their expecting that, by the time the conference concludes, they will come away with something to show for all the time, energy and hard … Read more
One of the limitations of Direct Air Capture (DAC) of carbon dioxide removal from, for example, the lower atmosphere – where, as we know, is currently at a density of nearly 420 parts per million (roughly 50% more concentrated or dense than it was when the Industrial Revolution first came into being in 1750 – … Read more
