Benjamin DeAngelo @bendeangelo.bsky.social · 01/10/2026Surreal experience as someone who worked on EPA's original GHG endangerment finding. My main message today: EPA is taking the extreme position that the only way it can be consistent with congressional intent and Supreme Court decisions is to do *nothing* to curtail emissions of GHGs 000

Benjamin DeAngelo @bendeangelo.bsky.social · 05/05/2026I was interviewed for this article. We thought climate adaptation work at EPA would be supported. It's always been and from my experience still is bipartisan. You prepare for change. It's as simple as that. www.eenews.net/articles/ada...eenews.netAdaptation was supposed to be safe under Zeldin. It didn't turn out that way.The EPA administrator once touted the importance of climate adaptation programs. Now that he's in charge, he's taking a different approach. 143
Benjamin DeAngelo @bendeangelo.bsky.social · 04/05/2026I've now wrapped up my first ever class teaching global climate change at Howard University.

Benjamin DeAngelo @bendeangelo.bsky.social · 30/04/2026Yes, your EPA which has the mission of protecting your health now assigns zero to the value of protecting your life from environmental harm. fortune.com/2026/04/01/e...fortune.comThe EPA just valued a human life at $0.

Benjamin DeAngelo @bendeangelo.bsky.social · 18/02/2026John Hannon and I share our own commentaries about EPA's move to repeal the 2009 greenhouse gas endangerment finding. Both John and I were members of the EPA team that developed the 2009 finding. bendeangelo.substack.com/p/american-t...bendeangelo.substack.comAmerican taxpayers and current and future generations deserve betterOur EPA decrees it has no authority to regulate greenhouse gases with already-rejected arguments, creativity under the Clean Air Act, and with no basis to invalidate the 2009 endangerment finding. 041
Benjamin DeAngelo @bendeangelo.bsky.social · 12/02/2026Today's EPA statement says that the endangerment finding was overreach by the Obama Admin. Actually, this process dates back to 1999 when EPA was petitioned to regulate GHGs under the Clean Air Act. That led to 2007 Mass v EPA Supreme Court decision which directed EPA to make a science-based finding 131
Benjamin DeAngelo @bendeangelo.bsky.social · 11/02/2026I'm quoted in this Politico article about the pending repeal of EPA's 2009 GHG endangerment finding which I had a large hand in. We shall see to what extent EPA makes scientific arguments in the repeal. EPA's proposal didn't have compelling scientific justification www.politico.com/news/2026/02...politico.comTrump EPA to take its biggest swing yet against climate change rulesWith its plans to revoke the endangerment finding, the administration is gambling that the Supreme Court will allow it to completely avoid regulating the nation’s top greenhouse gas sources. 100
Benjamin DeAngelo @bendeangelo.bsky.social · 30/01/2026This EPA decided not to count benefits of pollution controls. No quantified accounting for avoided morbidity and mortality. This abandons decades of cost-benefit practice, economics and science. Claims that $ benefits estimates are too uncertain don't hold water theconversation.com/epas-new-way...theconversation.comEPA’s new way of evaluating pollution rules hands deregulators a sledgehammer and license to ignore public healthIn the world of cost benefit analysis, if an impact isn’t monetized, it doesn’t exist.
