Californians have now been sheltering in place since March 20. While social distancing is slowing the spread of COVID-19, it’s also significantly reducing air pollutant and greenhouse gas levels across the state. Residents from San Diego to Sacramento are seeing clearer skies and breathing cleaner air, even in the center of cities that rarely experience a noticeable reduction in air pollution

The saving of the ozone layer is a global success story that is repeating itself in the field of climate action, regardless of what the pessimists say

A study of 6 urban areas in the US conducted over 18 years finds pollutants from burning fossil fuels lead to higher levels of lung disease and early death. Does that mean we should do something about the problem?

We may not even see them, but tiny particles, particulates in the PM2.5 size range, are able to travel deeply into the respiratory tract. PM2.5 infiltrates the lungs, all the way to the alveoli, where oxygen is transferred into the bloodstream. Exposure to nitrogen dioxide and fine particulate matter, or PM, can cause grave trouble with one's health

The latest US midterm is over — or nearly over — and Democratic candidates had a record wave of support from voters, but there's still plenty of misunderstanding to clear up. We've gone through decades of misinformation campaigns, gaslighting, and political dystrophy. One blue wave doesn't mean we've got everything in order.
One topic I was recently inspired to address is a simple one, but one that seems to skate under the radar of public consciousness

More than 95% of the world's population in 2016 (+7 billion) lived in areas with dangerously high levels of air pollution -- that is, in areas where WHO organization guidelines for air quality (themselves likely an underestimate) were exceeded. This is according to a new annual report from the Health Effects Institute (HEI)

The rising air pollution levels in many of China's largest cities are having a pronouncedly negative effect on human health there. Though, that much has been known for quite a while now. A new study, however, has unearthed something not unexpected but still worth taking note of — "robust evidence" that rising levels of short-term ozone exposure are ramping up mortality rates considerably

As we’ve been looking at in our series, air pollution is a serious global problem that is having a huge impact on the health of the world population, as well as being a massive drain on the economy. More than 90% of people on earth live in areas where air quality exceeds the limits recommended by the World Health Organisation, so it really is an issue that affects almost everyone

The US Environmental Protection Agency and its controversial Administrator, Scott Pruitt, have been forced to back down from delaying the implementation of Obama-era regulations designating areas impacted by excessive levels of ground-level ozone, or smog.

Ozone air pollution has now been directly tied to the risk of developing cardiovascular disease, which expands the list of health effects known to be caused by ozone exposure, and also lowers the threshold at which ozone is known to be dangerous (by a fair amount)

Even as the Republican majority in the House is shutting down the science associated with air pollution, and has passed an astounding 168 bills hampering the EPA's ability to collect data on (or act to prevent) the harm of pollutants, the EPA is making improvements in its ability to study the interaction of weather and harmful air pollution. (What dedication!)
The EPA today announced a more up to the minute refinement of a decades-old method gathering its data: the Community Multi-scale Air Quality model (CMAQ) that the National Weather Service uses as the model to produce daily forecasts for ozone air quality and other harmful health effects of dirty energy use.
The new modeling improves forecasting ability, in predicting for example the daily danger level of smog over natural geological "basins" like Los Angeles.
But the Republican Party has other plans

The Republican Senator Rand Paul of Kentucky introduced S.J. Res 27 on September 8th, a resolution that would force EPA to scrap next January's EPA implementation of cap and trade under the Cross-State Air Pollution Rule (CSAPR) entirely. Then on September 12th, Republican House member Stephen Fincher of Tennessee introduced H.R. 2891 in the House, that would delay implementation by a decade.
Can Republicans prevent the EPA implementation of cap and trade to cut ozone pollution
