Thank you @governor.ca.gov for vetoing SB34 - a bill that would have tied the hands of local air regulators at CA’s busiest ports. Strong air quality protections are essential for protecting health + fighting climate change. www.reuters.com/sustainabili...

Air pollution isn’t just about asthma or heart disease, but it can also impact fertility. Harvard research found higher exposure to fine particulates linked to a 10% rise in infertility risk. Science like this underscores why air monitoring matters. www.nytimes.com/2025/10/08/c...

New research from the University of Michigan shows large animal farms may be a hidden source of dangerous air pollution. These communities face higher particulate matter — the kind of pollution that damages lungs & drives chronic disease. Data makes the invisible visible. tinyurl.com/4h69ka9p

It’s the 8th annual California Clean Air Day! Clean air is a right, not a privilege. We’re supporting clean air today and every day with block-by-block data that helps communities + policymakers take targeted action for healthier futures. Join the movement: cleanairday.org/pledge/indiv...

California is doubling down on science. CARB’s new 5-year research plan will guide climate + air quality policy rooted in evidence, even as the federal gov walks away. At Aclima, our hyperlocal data helps make this vision real: cleaner air, healthier communities. ww2.arb.ca.gov/news/carb-ad...

Wildfire smoke kills 40,000 Americans each year, a toll that could nearly double as climate change fuels bigger, longer fires. Clean air is a public health necessity. We need prevention, adaptation & community-level monitoring to protect lives. www.npr.org/2025/09/19/n...

A Spare the Air alert in the Bay Area was issued today. Children, older adults & those with asthma/heart conditions are most at risk. Cleaner air starts with better data + everyday action. Aclima’s technology helps us get there. www.sfchronicle.com/weather/arti...

Lower bills. Cleaner air. Better data. CA’s new laws extend Cap-and-Invest and boost community air monitoring so investments land where they matter most. Evidence = outcomes. www.gov.ca.gov/2025/09/19/g... #AirQuality #HealthEquity

Just 30 minutes of air pollution exposure can inflame the placenta, disrupting the organ that sustains new life. Pollution’s impacts begin before birth. Clean air is essential for healthy pregnancies & communities. www.livescience.com/health/ferti...

Air pollution is fueling the #1 global killer: heart disease. Exposure to PM2.5 is linked to a 31% rise in premature deaths + disability since 1990. What we breathe shapes how long we live. www.medicalnewstoday.com/articles/air...

An $88M satellite to track methane has been lost in space. Thank you @esmestallard.bsky.social & BBC News for this reporting: bbc.com/news/article... Aclima’s approach? $27M to measure dozens of pollutants block-by-block across 64 CA communities—turning invisible pollution into actionable insight.
