How climate change impacts air quality
Climate change is impacting our communities. We now experience hotter weather, storms with more intensity and less predictability, floods, and longer pollen seasons. Individual impacts add up and lower air quality over time.
- Hotter weather, with more days over 90 degrees
- Increased ground level ozone/smog
- Increased exposure to allergens (like pollen)
- Increased impacts from wildfire smoke, even far away from the actual fires
