Environment
Air quality in Boston is getting worse, according to a new report by the American Lung Association.
As part of its “State of the Air” 2025 report, the American Lung Association reported that 46% of Americans live in places with unhealthy levels of ozone or particle pollution. There are 25 million more people breathing what they call “unhealthy air” compared to last year’s report.
This is largely the result of extreme heat, drought, and wildfires, despite decades of successful efforts to reduce sources of air pollution. Eastern states were most recently impacted by a blanket of smoke from wildfires in Canada, which the report described as “unprecedented,” and this drove up levels of ozone and particle pollution.
The Boston–Worcester–Providence metro area was ranked the 61st worst for high ozone days out of 228 metropolitan areas, 114th worst for 24-hour particle pollution out of 225 metropolitan areas, and 110th worst for annual particle pollution out of 208 metropolitan areas.
Although all those levels are better than they were in the late 1990s, thanks in large part to the Clean Air Act, they have been on the rise since hitting lows a few years ago.
“Over the last decade, however, the findings of the report have added to the extensive evidence that a changing climate is making it harder to protect this hard-fought progress on air quality and human health,” the report said.
Suffolk County received a C grade for high ozone days and a B grade for 24-hour particle pollution.
Many of Suffolk County’s 768,425 residents fall into one of the American Lung Association’s at-risk populations: 121,787 are under 18 and 106,606 are 65 and over; 78,242 adults and 7,148 children have asthma; 31,030 have COPD, 362 have lung cancer, and 37,206 are affected by cardiovascular disease.
No Massachusetts counties earned “A” grades for either particle pollution or ozone grades. The full list of grades is below.

Boston Marathon

Name: Brianna Poehler
City/State: Granby, Mass.
I am running the 2026 Boston Marathon with Miles for Miracles in support of Boston Children’s Hospital. The Boston Marathon is deeply personal to me and my family.
My daughter is a liver transplant survivor, and at just 11 months old, she received a life-saving liver transplant at Boston Children’s Hospital.
What could have been the most devastating chapter of our lives became a story of hope, resilience, and extraordinary care because of the BCH team.
When our daughter was so small and so sick, the doctors, nurses, and staff at Boston Children’s carried us through the unimaginable.
They combined world-class medical expertise with compassion that went far beyond treatment plans and hospital rooms. They cared for our daughter as if she were their own. They supported us as anxious, exhausted parents. They gave us answers when we had questions, and reassurance when we were overwhelmed.
Most importantly, they gave our daughter a second chance at life.
Today, she is thriving because of that gift. Every milestone she reaches is a reminder of the miracle she received and the team that made it possible. Running the Boston Marathon is my way of honoring that gift and saying thank you in the most meaningful way I can.
The marathon is a test of endurance, determination, and heart — qualities I saw in my daughter during her fight and in the Boston Children’s team every single day.
With every mile I run, I will be thinking of her strength, her transplant journey, and the families who are walking similar paths right now.
By running with Miles for Miracles, I hope to raise funds that will support groundbreaking research, life-saving treatments, and compassionate care for children like my daughter. This race is more than 26.2 miles — it is a celebration of survival, gratitude, and hope.

Today is a First Alert weather day. A system to our south is pushing mix of snow and rain into southern New England through this evening and tonight.
For us here in Greater Boston, expect snow to continue spreading over our area through the afternoon/evening commute. In fact, parts our area could see up to 1 to 2 inches of snow accumulation before the sleet and rain move in.
Much of Greater Boston will likely see snow amounts on the lower end. Higher snow amounts are expected toward southern New Hampshire and along and north of outer Route 2. Also, some ice accumulations are possible, up to a tenth of an inch, creating a thin glaze here and there.
Dozens of schools in Connecticut and Massachusetts have already announced early dismissals as a result of the storm.
While this system won’t cripple our area, conditions could still create a mess on the roads during the evening commute through tonight. Be careful while driving. A Winter Weather Advisory remains in effect for parts of our area through early Wednesday morning. High temperatures will be in the mid to upper 30s today. Overnight lows will drop into the low 30s.
We’ll wake up to patchy fog Wednesday morning before the sun returns. High temperatures will be in the upper 40s. We’ll stay in the 40s on Thursday with increasing clouds. But by late Thursday night into Friday, wet weather returns. Some snow could mix with the rain into Friday morning. Highs will be in the upper 30s Friday.

Warmer weather is expected this weekend. Highs will be in the 50s Saturday and possibly near 60 on Sunday.
