Simon Rosanka & I estimated how many people do not die every year due to implementation of the 1970 Clean Air Act. It's a lot. CAFE standards safeguard climate & air quality. American manufacturers will fail to innovate & lose more ground internationally. We'll pay with our health.

At Region 2 on 9/11 I immediately started working on air quality networks/sampling. When Whitman announced NYC's air was safe I said to colleagues, NYC doesn't attain the standards & can't be safe. Why have sampling in the first place? Thank you, Mr. Stewart & everyone www.cnn.com/2026/09/08/u...

My colleague Barbara Finlayson-Pitts organized a Shakespeare-science event with Veronique & Lisa. I'm excited to help. My school sent out an email about the event. In a slight rephrasing of the original, All the world’s a stage, and all the scientists merely men.

OMB has demanded that all federal agencies implement its proposed rule that would give political appointees veto power over peer review & allow the government to cancel active grants mid-project with minimal justification. Please consider submitting thoughtful comments. agu.quorum.us/campaign/NSF...

Submit your comment now to help stop NSF from implementing harmful grantmaking changes
A new proposed rule would rewrite the terms of U.S. science at NSF. Submit a comment today to fight back.

Yesterday Trump signed an Executive Order creating a “Policy/Career” category of federal employees, removing many of the protections against politicization of the civil service. There’s what the EO says, and then there’s what it really means - a 🧵 on driving truth out of agencies 1/7
