A bittersweet series about what we have lost, but also what we could regain if we lived in a country that supported basic research again.

Very cool new research from @mekevans.bsky.social and Jamie Yazzie - 'Drought stress detected in tree rings suggests an impending tipping point for forests on the Navajo Nation' www.sciencedirect.com/science/arti...

“Terrible things are happening outside. Poor helpless people are being dragged out of their homes. Families are torn apart. Men, women, and children are separated. Children come home from school to find that their parents have disappeared.” Diary of Anne Frank January 13, 1943

"Should Universities work together to fend off the administration's attacks on academic freedom and free speech?" is a key question that rank-and-file faculty (i.e., @aaup.org) are answering in the affirmative and University administrators are mostly shrugging off. Time is running out.

USGS scientists tell us about the effects of invasive species & climate change. Yet their fate, like many other federal employees who work in science & the environment, is unknown. My latest for @nrdc.org. Thank you to @meadekrosby.bsky.social, John Organ, Ed Arnett, and others for speaking with me.

Strong statement today from UC's Academic Senate:

History has many painful lessons.

Out today in @science.org, we show wildfire disasters have surged in the last decade, as climate change intensifies fire weather and exacerbates other vulnerabilities. 📄 www.science.org/doi/10.1126/... With @pyrogeog.bsky.social @climate-guy.bsky.social

There is a gulf in America. I submit it is the gulf between good and evil, or at least not-evil and evil. The gulf is not just between people who oppose this and people who are indifferent to it or reluctantly accept it in support of immigration policy or see it as collateral damage. /1

Anticipating steep cuts to its budget, the National Center for Atmospheric Research, one of the world’s leading climate research centers, has laid off 29 employees and decided not to fill 21 vacant positions. https://scim.ag/46yaM9g

Really cool story - bird species from across the world make the same sound to warn against cuckoos, and they can even understand each other. Feeds into ideas Darwin had about the origin of language! www.newscientist.com/article/2498...

Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social 🌊 www.science.org/doi/10.1126/...

🚨New paper 🚨@natgeosci.nature.com Greenlandification of Antarctica - comment by me + colleagues @dmidk.bsky.social @eo4cryo.bsky.social + @universityofleeds.bsky.social showing how Antarctica increasingly resembles Greenland- drawing on a mass of work from @esaclimate.bsky.social rdcu.be/eJiqJ

You might think that the mayor of Yellowknife, the capital of Canada's vast Northwest Territories, would be a fan of giant pickups. Nope. He's disgusted by car bloat. www.linkedin.com/posts/benjam...

Congress told us to “Go Fund Yourself.” And with your help, we can. Our federal funding might be gone, but we’re still here. Public media needs your support now more than ever.

This will be an essential resource, and my hope is that it makes it easier for academics who are called to public scholarship as a way to fight the encroaching darkness.

Visualising historical changes in air pollution with the Air Quality Stripes Website: airqualitystripes.info And paper led by @kirstypringle.bsky.social and @jimmcquaid.bsky.social now published which visualises trends in air quality across many global cities: gc.copernicus.org/articles/8/2...

If you’re a journalist writing about a certain piece of UK climate policy news this evening, please ask the Science Media Centre for the many reactions from expert climate scientists and then please include some of their quotes in your story. Thank you.

I am filled with so much love and gratitude that I cannot grieve. Dr. Goodall worked tirelessly in her gentle, hopeful way for a better world for all life on Earth. She has laid down her field notebook for the last time; now it is for us to fill with wonder, joy, and connection, into infinity.

Do tropical systems ever fully merge via the Fujiwhara effect? Here's a classic example from 2022 in the Indian Ocean: TC Vernon and Invest 93S.

And with the 15z advisories -- #Hurricane #Imdelda & #Humberto are just 479 miles apart. This might be the closest two simultaneous hurricanes have ever been in the Atlantic basin in the satellite era (since ~1975). Close enough for their outer sfc circulations to interact as well.

"After nearly 40 years, the Arctic Research Consortium of the United States, or ARCUS, will close September 30." "The Arctic Research Consortium of the United States funded programs that aided Indigenous communities and tracked melting sea ice, among dozens of initiatives."

Hey fluids friends, we're recruiting in my department this year!

I started pumping my first at the pull quotes alone. This essay is a tonic. Drop everything, read it, share it, assign it.

fun read!

Justice Kavanaugh: “If the person is a U. S. citizen or otherwise lawfully in the United States, that individual will be free to go after the brief encounter.”

This is PRECISELY why folks can't take just one forecast and use it as gospel over a period of time. The models for #TD9 were super tricky, and 48 hours ago we were thinking about a landfall in the Carolinas as a possibility. Now it's going to take a literal right turn!

My Meteorological explainer of why Imelda likely takes a hard right away from U.S., what changed and the role of #Humberto too www.forbes.com/sites/marsha...

#Humberto is now a Cat 5! It’s the first time in nearly a century with back to back seasons with Cat 5’s in the Atlantic. We are seeing our warmer future unfold in real-time, IMO. 1/

"oh it's just a fish storm" Hurricanes that never make landfall can induce rough surf and rip currents along distant shores. Humberto is the latest "fish storm" expected to produce these hazardous conditions over the next few days. www.weather.gov/safety/ripcu... www.nhc.noaa.gov/refresh/grap...

NEW: Income isn’t supposed to play a role in how much housing assistance FEMA gives families. But in some North Carolina counties, the highest-income homeowners received two to three times as much money after Hurricane Helene as those with lower incomes. With @theassemblync.bsky.social

When a hurricane can take off, boy does it take off: the 2025 Atlantic hurricane season story. Watch Humberto also rapidly intensify from a lopsided tropical storm to a major hurricane. Notable intensity changes: - 40 to 125 kt within 48 hours - 65 to 125 kt within 24 hours

It’s not the point of this story, but ICE jails now hold about half the number of Japanese Americans interned during WWII www.theguardian.com/us-news/2025...

I got to talk about this very issue on #WITHpod with @chrislhayes.bsky.social. An electricity cost crisis is coming. We need efficiency, smart technologies and policies, resilient infrastructure, and lots of clean energy. open.spotify.com/episode/32ps...

The tropical wave labeled 94L (no, I won't name it in advance) has warm water, moderate to low vertical wind shear, and plenty of moist air ahead of it. The system is partly over land today, delivering heavy rain and gusty winds to the Dominican Republic, Haiti, and the Turks and Caicos Islands.

Here's an interactive web simulation of the Fujiwhara effect, using @visualpde.com: lnkd.in/eaWCpKHF When two areas of rotating fluid - like hurricanes in the atmosphere - get close enough, they can influence each other (the 'Fujiwhara effect'). Click to add your own vortices and see what they do.

Why have I been making changes? I'm including more ocean regions! This webpage now features a subtropical North Atlantic domain. The anomaly charts still need work, but all domains depicting values like the one below should be functional again. kouya.has.arizona.edu/tropics/SSTm...

With everything going on, I'm particularly appreciating this: getting some really great, clearly-thinking-hard-about-the-material, questions from students this semester.

The "U.S. Climate Collection" is now open for proposals! A joint initiative of AMS and @agu.org, the Collection will help sustain the momentum of U.S. climate assessment research. Learn more and submit your proposal: bit.ly/46JuY71

Some people think ChatGPT has a place writing things like news briefs, stuff written to a specific style and tone and, y'know, kinda boring. So Science did a study. ChatGPT failed. Why? It got stuff wrong. "Also, extensive editing for hyperbole was needed." www.science.org/content/blog...

Yet again, machine learning — even gussied up via the transformer architecture — encodes and reinforces societal biases. This study reveals that LLM-based peer review relies heavily on author institution in its decisions. arxiv.org/abs/2509.15122
