Absolutely absurd.
A new Louisiana law makes it illegal to use air pollution data to push for stricter controls or enforcement unless it's collected with expensive monitors that meet strict EPA standards. Community groups are suing, saying it violates their right to free speech.

Being a US-based scientist in 2025 feels like playing in the Titanic violin quartet. Might as well keep working on this data analysis...

📣🔥 New wildfire study: Blazes that cross into neighborhoods are much more deadly than remote wildfires, according to a new study led by NSF NCAR. In fact, fires that burn in the wildland-urban interface are 3x more likely to cause annual premature deaths.

Editorial (w/ Kelley Barsanti) just came out in Science addressing the challenge in addressing: Is the air we breathe safe? It is challenging to address as a growing number of different pollutants are being released into the air these days.
