The Air We Breathe Is A Health Equity Issue
Public health is rooted in prevention. We act when strong evidence shows that exposure causes harm. On air pollution, the data has been clear for decades.

“How can you go from science which was very, very strong in 2009 and is only stronger now in 2026 to saying science isn't strong enough to support it. You cannot. That's not a scientific judgment. That's a political judgment.” My statement in Time.

As I say here, there is no scientific justification to revoke the engagement finding. In fact, over the last 15+ yrs, the evidence of how climate change affects our health has only grown. Higher risk of allergies, dementia, fertility, heart disease, and death: that’s what’s on the line. @nature.org
There is No Scientific Justification to Revoke the Endangerment Finding
The U.S. EPA's decision to repeal the Endangerment Finding will limit the government's ability to regulate emissions of carbon dioxide and other greenhouse gases under the Clean Air Act.

YOU CAN PRINT THAT... honestly, too many outlets not being able to share this obvious and dangerous truth is a big part of how we've gotten to where we are.
“I don't see any plan, any strategy, any end game,” says Pat Parenteau, a professor of environmental law at the University of Vermont. “I don't see anything from this administration, just fuck everything up as much as you can. You can print that.”

Sounds accurate to me.
The Fight Over US Climate Rules Is Just Beginning

Cruel and unusual punishment:
“‘Why did that child not get to the emergency room first?’ Kotek asked. ‘They could have waited; they could have made sure that kid had what they needed.’”

??? gotta provide basic medical care before you take children to a detention camp with undrinkable water, inadequate food & a measles outbreak
“The 7-year-old Gresham girl who was detained on her way to see the doctor last month is only eating bread with mayonnaise and her family has to purchase water because the water provided at the Texas detention center where they’re being held is undrinkable.”

New from @gruberte.bsky.social and I in @science.org: The energy transition is at risk, and energy models are missing the threat. Fossil energy networks from oil to coal to gas have minimum viable scales of operation, and those thresholds are closer than we think:
