DC Climate Week!
*Tomorrow (Tues) I'll be participating in a panel, Climate Careers, Past, Present, and Future, at 10:30am at UofMD lnkd.in/eRDRZsZh
*Friday (April 24) 4pm will be moderating a panel at Howard U on Investable Resilience: Turning Climate Metrics into Capital, luma.com/kojy9eaa

Ok! That sounds like a good one over beers.

Every lecture for my climate class @Howard I get to cover an interesting topic (ok, in my very humble opinion) but today is one of my favorites: telling the story of the hugely successful Montreal Protocol and how it provided the template -- and unrealistic expectations - for climate negotiations.

Understanding the Endangerment Finding, Made Simple (with Benjamin DeAngelo) Spoiler: The thing that's endangered is your health, and the reason that matters is, well, reread this sentence.

Check out Climatific. New bloggers on climate and the environment. I interviewed with them on the basics of EPA's greenhouse gas endangerment finding and its recent repeal climatific.beehiiv.com/p/understand...

Great additional analysis on the EPA repeal of the greenhouse gas endangerment finding from someone who I know knows

EPA's previous analyses showed large net benefits. For the medium/light-duty rule alone, monetized benefits using SCC were on the order of $72B. Yes, now those benefits are assumed to be zero. Couple of us ex-feds who worked on 2009 finding have our commentary here substack.com/home/post/p-...

I love how it sounds like electronica but it's all old school humans playing instruments live

American taxpayers and current and future generations deserve better Our 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.

John 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...

The Supreme Court, not the Obama EPA, ruled that GHGs are air pollutants under the Clean Air Act. The first draft tech support doc with all supporting science that eventually supported 2009 finding was released for public comment under the Bush Admin.

Today'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

Of course EPA has now decided that it will assign the benefits of GHG or other pollution reductions, including lives saved, a value of zero.

EPN pointed out in their comments that the rules EPA is rescinding have positive net benefits. The Clean Car Rule avoids over 3,000 deaths and has annual net benefits of $96 billion. The Clean Truck Rule (phase 3) will save over 100 lives and has annual net benefits of over $10 billion.

Other arguments from last year's proposal seem to be at odds with the 2007 Mass v EPA Supreme Court decision, which held that GHGs meet the Clean Air Act's definition of an air pollutant and directed EPA to make a science-based decision whether GHGs cause endangerment

Trump EPA to take its biggest swing yet against climate change rules With 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.

I'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...

EPA’s new way of evaluating pollution rules hands deregulators a sledgehammer and license to ignore public health In the world of cost benefit analysis, if an impact isn’t monetized, it doesn’t exist. A former EPA official explains what’s changing now and why it matters.

This 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...

Did EPA Get the Climate Science Right in 2009? Spoiler Alert: Yes, we did.

I just posted the second in my Endangerment substack series: thesaraphreport.substack.com/p/did-epa-ge...

Anxious greens await death of endangerment finding Environmental groups are planning protests to oppose EPA’s upcoming move to repeal the scientific finding.

I was interviewed for this article in E&E News about EPA's forthcoming and expected repeal of the 2009 GHG endangerment finding. Remain very proud of the work we did for the original GHG finding and the work to uphold it in subsequent years. www.eenews.net/articles/anx...

What’s happening on adaptation at COP30? Adapting to our changing climate is getting more attention at the negotiations as we begin to breach the Paris Agreement’s 1.5°C goal. Key issues are indicators of adaptation and finance.
