Colorado Front Range had the fewest number of air quality alerts in 15 yrs, per RAQC. Mostly driven by an overall cooler summer, but citizen choices are making a difference too.

The momentum for clean indoor air continues to build. I attended the inaugural High-Level Side Event on indoor air quality at the UN General Assembly yesterday. Short remarks by Lidia Morawska @joeallenjoe.bsky.social @isiaq.bsky.social Pres. Kerry Kinney, ASHRAE, WHO, UNEP, many others.

I’m teaching an undergrad #AerosolScience course & highlighting real-world #careers. Looking for people who work in a job that heavily involves #aerosols in any broadly defined way for students to interview. Could be any aspect of aerosols: industry, engineering, medicine, etc. Want to help? DM me!

It’s always interesting to see the effect of fireworks on urban air quality. This is a simple snapshot of the #PurpleAir maps in U.S. and Europe tonight, with a bonus of the Colorado Front Range thrown in for good measure. Serious PM concentrations, as always on the 4th of July. Stay healthy!

Before humans began mining fossil fuels, CO2 was 280 ppm. Today at Mauna Loa, CO2 is 428. When I was born, it was 315.
3/4 of the fossil fuels that have ever been burned were mined post my birth. We need to stop burning stuff. We need @NOAA to keep these records so we will know whether we have.
