On March 15, the driver of a Lexus SUV fleeing a traffic stop killed 3 people on Rock Creek Pkwy in D.C. The Lexus has >$17,000 (originally reported as >$12,000) in unpaid moving violations, exposing many problems with D.C. traffic enforcement. 1/12 wtop.com/dc/2023/03/3-dead-2…

How can we use models to build consensus over the future of Canada/US energy integration? How can we address controversies and disagreements over the role of Canadian hydropower? New article by @EmilDimanchev @stuartcohen8, Ryan McManamay and me in ERIS (@IOPenvironment)

New perspective paper!
How can science better serve the needs of building a cleaner Canadian-US energy system?
We highlight gaps in public data & models, and argue for #opensource research.

What if we… coauthored a study on the economic damage wrought by parisitic mistletoe families Loranthaceae, Misodendraceae, and Santalaceae on commecial timber harvests

Closing out 2023 with a humblebrag about our paper 🐠 🎣
🔟First up on our Top Articles of 2023 Countdown is "Drivers of Atlantic #herring decline and evidence basis for fisheries closures and rebuilding plans" by @rycalder, Jenni L. McDermid, and @OceansStephanie (@FishOceansCAN). Read it here: ow.ly/kS9S50QitqL #BestOfCSP

Several grad students in my class said they refused to take public transit because human trafficking is out of control (it seems to be a big thing on TikTok)

Small sample size but in my time as a teacher it was becoming more and more noticeable just how many students had truly bizarre beliefs if you asked just a few follow-up questions to what they said. Wasn't the case when I started teaching.

hey 👋 please be mindful that many of us teaching-coded folx have been living in a “costume” every single day in the classroom and this is nothing to celebrate or be spooky about

Glad for @AminaSchartup's and my article to be selected for Editor's Highlight in @AguGeohealth! We argue that geohealth analysis of tradeoffs leads to policy *benefits* and that this is more relevant than policy *impact*.

Proud of @SafeStreetsDC work with @rycalder to push DC to reckon with its enforcement lapses and loopholes. Ensuring that the most reckless drivers are removed from the streets is a critical element of vision zero.

Too many people are being killed on US roads. Black, Hispanic & indigenous ppl are overwhelmingly victims.
While cities work to end discriminatory traffic enforcement, they must also find a way to keep streets safe. I wrote about it @voxdotcom:

A good day to recap our @EnvSciTech paper quantifying the net benefits of @CHPExpress and resolving some controversies in the cost-benefit analysis of U.S. imports of Canadian hydropower. pubs.acs.org/doi/10.1021/acs…

In Astoria for the groundbreaking of a critical new @CHPExpress converter station to bring clean energy directly into NYC - a major milestone for the City’s climate goals and the product of over a decade of work!

This includes >$4 billion in premature mortality in disproportionately African American/Hispanic counties.

Project opponents claimed this project will divert exports from upstate New York. We show that even if this point is 100% conceded, the project is still more cost-effective than alternatives and more cost-effective than suggested by New York State's cost-benefit analysis.

This was the case study used in our recent @EnvSciTech paper demonstrating that, despite the huge price tag, it is still vastly cost-effective given the generation and emissions it likely displaces pubs.acs.org/doi/10.1021/acs…

This will provide 20% (20%!) of New York City’s electricity with emissions-free energy from Quebec.

This figure shows environmental justice benefits in terms of avoided premature fatalities (deaths on left axis and economic value on right axis; both axes apphy to both panes) -- avoided fatalities are in disproportionately Hispanic/African American counties

We also demonstrated that the cost-benefit analysis used by New York State vastly underestimated benefits because it considered "cost of power" as a check written from NY to QC rather than the opportunity cost of how hydropower could be used elsewhere

To the extent possible, policy advice should reflect the tradeoffs, constraints, and priorities of affected communities (meaning: engage the communities your policy advice could benefit!) ... 12/13

Overall, we argue these strategies are key to unlocking environmental justice benefits from the highly convergent and potentially multidisciplinary and highly collaborative field of geohealth. 13/13 agupubs.onlinelibrary.wiley.…
