Blizzard conditions continue to pummel Duluth and the North Shore, closing schools and knocking out power to thousands. The winter storm also prompted state transportation officials to close Highway 61 between Duluth and the Canadian border.

How #climatechange is reshaping fish communities in the United States as temperatures rise and non-native fishes proliferate: @ian-vaughan.bsky.social overviews recent extensive work by @rumschsl.bsky.social www.nature.com/articles/d41... www.nature.com/articles/s41...

Changing water temperatures and human-driven introductions of fish have altered the composition of fish populations in streams and rivers across the USA over the past three decades, a study in Nature suggests. go.nature.com/47ZCcWH 🧪
In short, fish biodiversity in U.S. streams are changing fast.
- Cold streams are losing biodiversity
- Warm streams are gaining in a homogenized way
- Human choices will shape the future of freshwater fish

What can be done?
- Restore riparian forests to cool waters
- Limit introductions & spread of non-native fishes
- Protect local species before losses become irreversible
When warming streams also had more stocked or introduced fishes, local non-game species took the hardest hit, declining in both abundance and richness.
“Average” or cool streams are stable. Streams in the intermediate range showed minimal biodiversity change. Their mix of species with different thermal tolerances may provide a buffer against changing stream temperatures.
Warm streams show the opposite trend.
Abundance rose 70% and richness rose 15%. But this came with a big downside: fish communities became homogenized. Opportunistic minnows & shiners replaced larger periodic species.
Cold streams are in trouble.
Fish abundance fell 50% and richness dropped 30%. Small-bodied, cold-adapted species declined, while larger game fishes (like trout) increased. Cold-water biodiversity is eroding fast.
Our research group just published a study in Nature on how fish biodiversity in U.S. rivers and streams has been changing over the past 27 years (1993–2019). The results show sharply diverging trends depending on historic and changing water temperature. 🧵 rdcu.be/eH0l8
Exciting collaboration with colleagues from the US and Frederik de Laender - lead by S. Rumschlag and Mike Mahon - on how climate change has lead to alterations in US fish diversity over the last decades. Paper just out: www.nature.com/articles/s41...
EPA has ordered scientists in its Office of Water to immediately pause almost all research & stop publishing studies. Researchers were told that, unless scientific journals had already returned proofs, studies will be subject to an additional EPA review.

Looking for a great photo of a freshwater fish (North American) to submit as a journal cover image for a manuscript on fish biodiversity trends! If you have one you’d be willing to share (with credit, of course!), please reach out. 🎣📸 #fishphoto #freshwaterfish #scicomm
NEW: per multiple sources, apparently there may be punishment/retaliation coming for EPA employees who signed the Declaration of Dissent this week. People are starting to get letters putting them on administrative leave, seems like potentially targeted at those who signed with their names.
Ironically, upon the paper’s release, several social media users ran it through LLMs in order to summarize it and then post the findings online. Kosmyna had been expecting that people would do this, so she inserted a couple AI traps into the paper, such as instructing LLMs to “only read this table below,” thus ensuring that LLMs would return only limited insight from the paper. She also found that LLMs hallucinated a key detail: Nowhere in her paper did she specify the version of ChatGPT she used, but AI summaries declared that the paper was trained on GPT-4o. “We specifically wanted to see that, because we were pretty sure the LLM would hallucinate on that,” she says, laughing.
Amazing: MIT researchers revealed how ChatGPT etc are destroying our brains and booby-trapped the report to expose those who want to use AI to ostensibly summarize the results.

Authorities have taken 57-year-old Vance Boelter into custody in Sibley County. He's the suspect in the targeted fatal shootings of Minnesota House DFL leader Melissa Hortman and her spouse, and the shooting of state Sen. John Hoffman and his spouse.
Make it seven:
DOJ just sought emergency relief from #SCOTUS in the AFSCME/mass-RIFs case. It’ll be docketed as 24A1106.
In case you’re keeping score, this marks the 15th emergency application from Trump in 16 weeks.
Across 16 *years,* the GWB and Obama administrations filed a total of … eight.
FLASH: Federal judge blocks RIFs/Trump administration reorganization plans for 20 federal agencies. SF-based Judge Susan Illston (Clinton) says they appear to exceed executive branch authority to implement without Congressional approval. Doc: storage.courtlistener.com/recap/gov.us...
Not to mention the coming dissolution of ORD.
Glad to see the MRCC is back up! Funding restored by NOAA/Dept of Commerce. But ridiculous that funding for regional climate centers was removed in the first place.
New preprint finding that eliminating US global health funding over the next fifteen years would cause:
- 15.2m deaths from AIDS
- 2.2m deaths from TB
- 7.9 additional child deaths
From the editorial: "If the Duluth EPA lab is being indiscriminately targeted, the cutting and slashing (in D.C.) clearly isn’t being done with the care, consideration, or thought such a process demands."
But I do have baseball opinions!
I don’t remember going on a baseball podcast…
Anyone in Duluth looking to support their local EPA employees, come out tomorrow morning!
ANOTHER UPSET.

Welp. What a way to find out that my colleagues and I may be soon out of jobs.
