During the week of Christmas, Pittsburg, PA experienced an unusual heavy set of particular matter created by a temperature inversion that resulted in the trapping of pollution closer to the Earth’s surface. A temperature inversion is created when a mass of warmer air sits on top of and trapping of a mass of colder air, therefore preventing polluted air from rising. The event continued for six consecutive days in Pittsburgh. Rising temperatures in the winter could mean that similar “Super Pollution Events” involving dangerous levels of particulate matter in the air might become more common. Read More.
The National Bureau of Economic Research released a report this month investigating the recent increase in air pollution by region in the United States. After a decade of improving air quality with a decrease in the presence of particulate air matter by 25%, the United States has experienced an increase pollution between 2016 and 2018. The largest increases have stemmed out of the Midwest and West. The report speculates that pollution increases are the result of higher economic activity, lower environmental regulatory enforcement, and wildfires. Read More.
Next month, the former particulate matter advisory group will meet publicly to continue their work studying the effects of air pollution on human health, despite having been fired by the Trump administration a year ago. The group will convene at the same location it met last year to discuss the 21 million Americans that are subjected to adverse health effects from air pollution and pollution from fossil fuels. This is not the first time a group has reassembled to discuss environmental concerns despite dismissal from Trump’s EPA. Scientists and environmental experts are continuing to meet to fight for the health and safety of Americans suffering as a result of industrial pollution. Read More.
