The whole point of something like this is to get open Nazis and racists into the coast guard

U.S. Coast Guard will no longer classify swastikas, nooses as hate symbols
The military service, which falls under the Department of Homeland Security, has drafted a new policy that classifies such items “potentially divisive.”

This is bad. How can any university hire people, build facilities, make any plans, if the funding can be arbitrarily removed on a whim from an agency? This goes far beyond currently disfavored topics.
Update on a significant development NIH grant terms.

On 10/1, a change to grant making regs went into effect that gives NIH more power to terminate grants for policy reasons.

But to use this power, new grant terms must include specific language. See @aniloza.bsky.social w/ the story from July.

And I get that a lot of people like the abundance frame, and how obvious “cutting red tape” sounds as the path to providing all the things we want. But please understand how that framing is actually being used in real-world policymaking. #Abundance #PermittingReform
Some folks over at “Inclusive Abundance” the think tank promoting the “abundance agenda” have been complaining about Section 7 of the Endangered Species Act for quite some time.. looks like they’re getting their wish. bsky.app/profile/dust...
New ESA rules proposed by the administration revive earlier rollbacks, weaken habitat protections and section 7 consultations, expand economic exclusions for oil and gas, and offer fewer automatic safeguards for threatened species. #energydominance #permittingreform www.nytimes.com/2025/11/19/c...

This is a terribly misunderstood point, even in insurance circles.

Our estimates of the 1 in 100 flood are almost always extrapolations and depend heavily on our assumptions and a few (or zero) real events. In most cases, the 'actual' 1:100 flood could be ~20% lower or higher (at least).
The defense that this was just an adjustment based on better data is self-serving BS.

We do *not* know what the 100-yr flood level is - even if we had perfect DEMs.

Even if we had perfect historical data, non-stationarity means we don’t know what the level is *now*, let alone in the future.
