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.

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...

Calling all climate resilience people attending DC Climate Week. Save the date for April 24, 4-6pm. Am putting together an event hosted at Howard University, "Investable Resilience: Turning Climate Metrics into Capital." #DCClimateWeek luma.com/kojy9eaa

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

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...

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

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...

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...

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

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...

Yesterday I started teaching the undergraduate class on global climate change at Howard University. This is in their Dept of Earth, Environment and Equity. Always wanted to do more teaching after federal service. Honored to be part of Howard in this way!

Grateful to be part of this newly expanded team with earthknowledge.com as an advisor for climate adaptation and environmental risk. Earth Knowledge provides weather and climate information for use in decision making, including risk assessment and resilience planning.

Gwyneth Fries and I published the blog, the Business Case for Climate Resilience. Businesses and investors need to transition from viewing climate adaptation solely as a risk management strategy to exploring it as a driver of innovation. www.operationfuture.net/blog/the-bus...

Updated blog to reflect the final key decisions on adaptation at COP30. bendeangelo.substack.com/p/what-happe...

Thank you Penn State for this feature! Really humbled by it but hugely appreciate the support. WE ARE going to continue to provide Pennsylvanians and all citizens with the best available info to deal with a rapidly changing climate. www.psu.edu/news/earth-a...

Happy to announce I joined Silvestrum Climate Associates as a senior fellow focused on climate adaptation. Silvestrum bridges science, policy and law and focuses on nature-based solutions domestically and internationally. Great to be part of this mission-driven team! www.silvestrum.com

During #NYClimateWeek Louie Woodall of @climateproof.news sat down with me for this interview about my initial reactions to NYClimateWeek, gave me an opp to discuss my federal career working on climate, and my new venture Operation Future, LLC www.youtube.com/watch?v=0olG...

CALL FOR PUBLICATION PROPOSALS. I'm on an editorial board for a new Anthem Press series entitled "Law, Resilience and AI." We’re inviting authors to contribute to a new series that explores how law, climate resilience, and artificial intelligence intersect to shape societies today and in the future.

Was great to participate in this panel last week sponsored by @kogodbiz.bsky.social @americanuniversity.bsky.social. Lots of diverse perspectives on climate and the role of the private sector to advance progress in terms of certification, branding, and communication tools.

Today the National Academies will be releasing its fast-track report Effects of Human-Caused Greenhouse Gas Emissions on U.S. Climate, Health, and Welfare. Will be available here: www.nationalacademies.org/event/45701_...

Looking forward to being on this panel sponsored by American University's Kogod Sustainability Club. Friday, Sept 19, 11:30am ET. "Transformation through Sustainability"

⚠️ While extent will not be setting any annual minimum records this year, the average thickness of #Arctic sea ice is actually at historic lows for this time of year (in the dataset by PIOMAS). Thinner ice is younger and usually more fragile. More graphics of volume: zacklabe.com/arctic-sea-i...

Enjoyed being a guest lecturer yesterday @georgetownlaw.bsky.social in their Climate Change Law & Policy seminar to talk about role of scientific assessments in informing policy decisions, and the importance of process used to develop assessments for credibility and ultimately widespread use

Looking forward to attending #ClimateWeekNYC for the first time and making connections for my new venture to advise on and climate resilience and response strategies operationfuture.net

Happy to share that I'm open for business with Operation Future, LLC. Am offering consulting services to states, cities, tribes, private industry, professional associations, NGOs, and universities to become more resilient to our rapidly changing climate, and more. www.operationfuture.net

Have to hand it to my now former EPA colleagues for this very thoughtful parting gift. Am thankful for my drums during this time!

Sorry to hear this. This has been a prestigious & competitive fellowship program that has helped train next gen of science leaders. Alumni of this program are impressive. I had the honor of meeting fellows at AGU. While at NOAA we had the Sci Advisory Board review the program. It got very high marks

It's with a lot of mixed emotions that I'm announcing that last week was my last at EPA. I decided to take the offer to leave. I was hired as EPA's first director of the newly created Office of Climate Adaptation & Sustainability.

AMAP recently released three high-level summaries on important topics for the Arctic: plastics, radioactivity, and climate. I had the honor of chairing this group a while back and it's great to see this work continue and made accessible. Kudos to all in AMAP who made this work possible.

Open call for nominations for EPA's Science Advisory Board. Deadline June 2. A wide range of disciplines will be considered, including economists, behavioral scientists. Selected members expected to serve for 2- or 3-year terms to provide independent advice to EPA. www.govinfo.gov/content/pkg/...

Incredibly honored to be recognized by Am Society of Civil Engineers for work I did at NOAA forming a partnership to bring science of changing weather & climate into new standards. So important we no longer assume stationarity to make infrastructure more resilient for current & future generations.

The shrinking of the Greenland Ice Sheet can’t be stopped—but it can and must be slowed! 🏝️ 2024 was the 27th year in a row that the Greenland Ice Sheet shrank, losing ~269 gigatons of ice each year since 2002! 🧊🔥 Check this piece (time limited free access!) thebulletin.org/premium/2025...

EPA announced new Community Change Grants supporting communities to address pollution & vulnerabilities to extreme weather & climate. Huge demand signal. EPA received ~2,700 applications requesting more than $40 billion! To date, 105 grants have been awarded totaling nearly $1.6 billion from IRA

I should reintro myself after getting lots of followers thanks to colleagues more popular than myself. I recently returned to EPA as director of an office that works across EPA and partners w/ communities, states, businesses to protect health & environment in the face of climate & weather hazards
