**AIR QUALITY ALERT — PHILADELPHIA & THE NORTHEASTERN U.S.**
**Code Red Air Quality Alert** issued today for much of the Philadelphia region and large portions of the Northeastern United States.
Today’s unhealthy air is being driven by a dangerous combination of **ground-level ozone (smog)** and **fine particulate pollution (PM₂.₅)**. Everyone is at risk. Particularly vulnerable are children, older adults, pregnant women, people with asthma or heart disease, and anyone who spends extended time outdoors, all of whom face an elevated risk of adverse health effects.
But this isn’t just another bad air day.
It’s a preview of the future.
Climate change is creating the perfect conditions for worsening air quality:
More extreme heat creates more ozone.
More drought fuels larger wildfires.
Wildfire smoke releases massive amounts of PM₂.₅.
Those pollutants also contribute to additional warming through powerful climate feedback loops.
Air pollution is now the world’s leading environmental cause of premature death, contributing to **nearly 8 million deaths every year**.
I’ve just published a new article:
**”Air Quality and Climate Change: The Hidden Health Crisis of Global Warming”**
The paper explains:
• Why climate change and air pollution are inseparable
• How ozone and wildfire smoke are increasing across North America
• The major health risks—from asthma and heart disease to dementia and lung cancer
• The climate feedback loops making pollution worse
• One inexpensive solution that can dramatically improve indoor air quality: the DIY **Corsi–Rosenthal Box**
As our climate changes, clean indoor air is becoming just as important as clean drinking water.
Please stay informed, limit outdoor activity during Code Red conditions, check on vulnerable family members and neighbors, and consider building a Corsi–Rosenthal Box before the next smoke or ozone event.
Do yourself, your family, your pets, and even your houseplants a favor—build a DIY Corsi–Rosenthal Box.
