Saw this looking at property prices after Irma in the Fl Keys. Anything built or renovated substantially after the 2005 building code rose in price after the storm but anything built before went down

Oh, I am so sorry for your family's loss :( I hope you can find solace in happy memories and Gilda's permanent impression on you. I still miss and think about all of our family dogs over the years

Love this take. Nothing feels more rewarding than the "art" of doing science

Thanks for the great tips! IIHR dam is pretty close to one of our daily routes but I usually avoid because I'm worried he'll pick a fight with an eagle he can't win πŸ˜‚

Wow! Where along the river is this?

So dumb - this isn't a problem at all. So sad that they're not smart enough to work on and address important social problems. Maybe if they had a better gen ed background and learned how to think critically in classes like CRT, environmental racism, or EJ!

Wow. Any ideas on how this might translate into spring flooding, especially in mountainous areas of the Northeast?

Thanks for explaining. This reminds me of narrow ways the courts decide on environmental justice cases about waste facilities siting - need to prove discriminatory intent but the EJ perspective includes historical segregation (incl. fair housing violations). Trying to wrap my head around this

Specifically wondering what the "other things" are in "The companies urged lower courts to dismiss the case, arguing among other things that Boulder's lawsuit would illegally interfere with the federal regulation of greenhouse gas emissions under the Clean Air Act."

Legal noob question - what is the argument that they don't have standing to sue? People file and lose lawsuits all the time. What is unconstitutional of anyone suing a firm and having to prove damages?

I shouldn't have said "good" benchmark. I meant "ideal"

The "are claims a good benchmark" q is important. Probably not, but follow up q for you. Do you expect homes that flood but don't have insurance to in general have higher or lower damages than those reflected in the claims data?

This paper looked at First Street's estimates under the "present" climate, not the future. This paper evaluates their model's skill historically, which is valuable (but still incomplete) for understanding it's trustworthiness about the future

I know that USACE uses heuristics (e,g, sidewalk height) to filter low depths from flood models. Don't know how FS or others handle that, if at all. But still, 2 inches of flooding could be quite damaging! It's just unlikely that every single place with that estimate will be damaged at all

National structure inventory (NSI) gets important locations, foundation types, and structure values wrong and this influences risk assessments a lot - papers.ssrn.com/sol3/papers.... (in 2021 I think FS used an even less accurate version of the NSI)

New Empirical Models for Flood Loss Prediction and Implications for the Coterminous United States Flood-loss estimates are needed for floodplain development and mitigation projects, for setting fair insurance rates, and for guiding climate adaptation policy. Currently, flood-loss models, including...

This paper is awesome. My two cents: (i) We got lower CONUS AAL than FS in www.nature.com/articles/s41... because we used a more accurate building inventory. (ii) FS estimates lots of low inundation, and DDFs really run away with that! (see fig 7 www.researchsquare.com/article/rs-2...)

So presidents can or can't declassify things just by thinking about it?

Between this and reporting on endangerment I’m starting to think that either real issues are too complicated for generalists (charitable way of saying this) or LLMs are writing everything. Hopefully history will look unkindly on this week (year) for the 4th estate

You can't... repeal... a scientific finding. At that point it's just called lying about it.

Trump's EPA *rejects* scientific & legal basis for endangerment finding due to corruption and lying

Trump nominated a legit white nationalist to a top post at the State Department. I asked him some basic questions about his belief in the β€œerasure of white culture”. Watch this embarrassing, fumbling answer. Like he has never before been asked to explain his views.

Nice write up! And not just because Emily makes me sound good! (I think - open to feedback!)
