Hey Colorado! I'll be in town on April 21 to keynote this event at the University of Denver. My topic: How electric and self-driven vehicles can — and can't — make streets safer, cleaner, and more vibrant. Registration is $20, or whatever you can afford: www.eventbrite.com/e/the-road-a...

To counter the proliferation of AI beaver slop and support people like Jake, here is a Dropbox containing a decade of photos of beavers and their landscapes. Use these as you see fit in reports, presentations, story maps, or for your personal viewing pleasure. www.dropbox.com/scl/fo/ho24s...

Migratory freshwater fish populations down 81% since 1970 (when they were *already* at a tiny fraction of their historic abundance, at least in North America and Europe). www.theguardian.com/environment/...

Have walked this ditch for years and literally never seen it dry till today. Ominous.

Today would be a great day for Carson Benge to hit a rocket off Paul Skenes. Happy Opening Day and #LFGM!

Turns out those Chinook salmon that finally showed up in the Upper Klamath last year were doing more than just posing for photos. 🐟🧪🌎 www.opb.org/article/2026...

As the first reanalysis data become available, I think I can say with a fairly high degree of confidence that the March 2026 heatwave will go down as the most anomalously extreme heat event ever observed at any time of year in the southwestern U.S.

What's wild is that this current war is indistinguishable from a deliberate plan to frighten countries away from petrostates & into the arms of the world's dominant electrostate.

“The more people you put in the woods, the more fires you’re most likely going to have.” Terrific @insideclimatenews.org story on new study refuting the Trump Admin’s claim that rescinding Roadless Rule will reduce fire risk in national deforests. #roadecology insideclimatenews.org/news/2403202...

Aside from being a classic of narrative journalism, I've always thought Mountains Beyond Mountains would be a great model for a conservation book: a globe-trotting profile of a character through whom we explore deep issues. Who is the Paul Farmer of, like, pangolins, or sturgeon, or lemurs, or…?

For the last time, you’re too big to ride in the stroller now. You can walk on your own hooves.

Amid the historic and ongoing record heatwave (which will continue for at least another week in this region), Colorado River Basin snowpack has unfortunately taken an unprecedented March nosedive. Given the pre-existing water crisis, this is a highly alarming trajectory.

Here’s some obvious AI garbage, purporting to depict beavers, just posted to a prominent nature news site. Alas, by devouring thousands of mislabeled nutria photos, it appears that AI has developed an incorrect perception of what a beaver actually looks like. This is straight #NutriaSlop.

Coming to the US in June from @robgmacfarlane.bsky.social: The paperback of his NY Times bestseller IS A RIVER ALIVE?, and his third magnificent collaboration with the artist Jackie Morris, THE BOOK OF BIRDS.

Beavers fucked around and took down a lodgepole 😳

Accursed phenology 😭

This week in Colorado we have April hatches, May flows, June temperatures, and Western European fish. 🫠

We ain’t got snow but we got 🦫 🦫 🦫

I reviewed Pixar's new movie Hoppers, which came frustratingly close to understanding what evil looks like defector.com/dam-it-all-t...

Just need Ben Shapiro to chime in with some beaver slander and all my boxes will be ticked

Polymarket now taking bets on whether/when Trump will bomb the carp.

Also: a print book doesn’t introduce subscription fees, harvest your data, require you to download a shady tech company’s app, or tweak an algorithm to show you shit you never wanted to see; nor can it be magically deleted from your shelves. Why yes I *am* reading Enshittification; how’d you know?

“The other team is a bunch of wienies/ We’ll hunt ‘em down with ampullae of lorenzini(s)”

An impossibly broad prompt for any who care to respond: What inherent rights do fish possess? What legal rights should they have?

I'll take any excuse I can get to post fish smut.

I second this motion! Disclosure: I am a credited science advisor to this film, though my contributions were pretty minimal, so I’m not an unbiased reviewer. But if someone wants to run a full-throated endorsement of the most ecologically intelligent animated movie since WALL-E, I’m your guy. 🦫 🫡

Given lit trends, I'm rebranding my book as smut. It's about the romance of salmon, who navigate oceans & rivers to fuck & perish. It's about the sensuous slithering of lamprey; the orgiastic joy of herring; the bondage of male anglerfish. Cover art depicts a bull shark in a bodice. Ichthyoerotica.

Attn beaver believers: the Good Rodent gets plenty of well-deserved love in GRIZZLED, alongside a veritable menagerie of phenomenal critters, all told in Jason’s inimitably good-humored and wonder-struck style. Nab your copy today! 🦫 🦫 🦫

Omnishambles is the new polycrisis.

Great quotes in military history. @atrupar.com

I'll have more to say about this by Tuesday, but...yeah. No Miracle March in the cards for Western snowpack this year--quite the opposite, in fact. I'll take a closer look and have a livestream and blog post soon to discuss.

Enjoyed this little meditation on the unsung ecosystem engineering of kangaroo rats. Keystone species everywhere! www.biographic.com/the-rodent-w...

It’s ya boy with his first (and presumably last) Pixar credit. Huge thanks to the HOPPERS team for consulting me on a film that combines beavers and #roadecology, and glad they learned from the best in @emilyfairfax.bsky.social. Can’t wait to see this 🦫 cinematic masterpiece in a theater!

The U.S. Army Corps of Engineers is planning to widen the shipping channel leading into Port Everglades, blasting through a coral reef and dredging up sediment that could smother acres of coral, federal scientists say. https://wapo.st/4r7kRAU

NEW: Mamdani's City Hall is discussing charging fees for currently free on-street parking — a policy change that would not only create a new revenue stream but also seize a once-in-a-generation opportunity to improve the streetscape. buff.ly/9C0Iq34

anyone happen to have a PDF of this paper, on the aquatic "vibroscape"? ben.a.goldfarb at gmail dot com thanks! pubs.aip.org/asa/jasa/art...

If you need a nugget of (mostly) good news this morning, I recommend this @mongabay.com story about a training and compensation program that incentivizes Indian fishermen to release whale sharks. Lotta good conservation lessons here. news.mongabay.com/2026/02/whal...

Honored to have an excerpt from my book, "In Trees" (out 4/7) in the pages of this week's @newyorker.com This piece is about the summer I spent in a treehouse to blockade an oil pipeline, and why some protest movements change history, while others fade quietly into obscurity.

Dawg if I was a cookie-cutter shark and found out that my species could have been known as the "demon whale-biter" instead I'd be fuckin' *pissed*. Absolute nomenclatural humiliation. journals.plos.org/plosone/arti...

In 8 days, my picture book, WHEN BEAVERS MOVE IN, hits store shelves. It tells the story of what happens after beavers are relocated and was partially inspired by EAGER by @bengoldfarb.bsky.social. Check out Ben's overview of the Tulalip Beaver Project, also highlighted in my forthcoming book.

Thought this was a bleakly brilliant rendering of our near-term future and the forces (i.e. run-amok military AI and the Derangement of climate change) that might get us there. It’s also about the overwhelm of the digital age, the narrow obsessions of writers and scholars, and so much else. Five ⭐️s.

The sensory pores on a paddlefish’s rostrum are sufficiently sensitive to detect the electric currents generated by zooplankton. The frilled shark has a gestation period exceeding three years. Arapaima nurse their offspring with milky fluid from glands in their heads. I accept the nomination.

BEHOLD the largest freshwater fish species in the world: the Beluga Sturgeon! FINALLY got to see one in person at the Great Lakes Aquarium in Duluth along with the @garlab.bsky.social Team at the @mnafs.bsky.social @amfisheriessoc.bsky.social meeting! What an incredible fish!

New York-ass staff never been to the damn desert

This is one of the things I am constantly (including in our book, Life After Cars) trying to get people to care about! This is killing us, folks

I stopped by @moonpalacebooks.bsky.social in Minneapolis today to sign anti-ICE copies of TIGERS BETWEEN EMPIRES. Get them Saturday, Feb 28 during "Authors for Minnesota Day" in support of local Minnesota bookstores and raising funds for the protection of civil rights. More: shorturl.at/o32PZ
