When we cut critical Federal funds for science, we all pay the price. The impacts of this loss of scientific innovation will be felt especially acutely in our coastal communities. Check out my latest op-ed, published today in The Philadelphia Inquirer, to learn more! share.inquirer.com/iC6tHv

My colleague, environmental scientist @andrajgarner.bsky.social, has a paper out about the variability and inconsistency of spring weather being a climate change concern. Tomorrow the forecast calls for a 40° change in temperature. (Never mind a third consecutive day of 90+ in May.)

Today, the University of Maine's Vice Chancellor for Finance and Strategic AI Integration (who made $243,000 last year) sent UMaine campuses an announcement that we have partnered with OpenAI with a contract for ChatGPT Edu. I sent him the following questions:

Excited to share our latest work, published today in Eos! The U.S. has led and helped to fund about a third of all global sea level projections ever produced. Now, attacks on science in the U.S. have left the field at a precipice.

Excited to see our paper on springtime temperature variability get some coverage from @bloomberg.com! I was glad to contribute to this piece by @eroston.bsky.social

Had a great time hosting "Chasing Ice" with students in my sea level course @rowancsm.bsky.social's Edelman Planetarium last night! We had a fantastic turnout, and the students did a great job discussing sea level rise impacts with our audience after the show!

Glad to provide comments for a piece in Le Monde newspaper discussing a new study about sea level adaptation pathways in Venice! This type of flexible adaptation pathway will be vital as our coastal communities look to become more resilient in an uncertain future. www.lemonde.fr/planete/arti...

As I've watched temperatures push toward the 90s this week in New Jersey, but see the forecast lows that will threaten a freeze by early next week, it brings to mind the paper that my colleague Dan Duran and I published two years ago. journals.ametsoc.org/view/journal...

My resignation letter

This past week, I was in Washington, D.C., where I had the opportunity to join colleagues from @agu.org for visits to our legislative offices. Together, we advocated for continued support of Earth and space science. It was a busy week, but very energizing!

It's been a busy few weeks of travel, starting with the Ocean Sciences Meeting in Glasgow, Scotland! We had lots of excellent talks and posters in the sessions we convened on Dynamic Coastlines in a Changing Climate. It was great to hear more about the exciting work being done in this area! #OSM2026

Coming up at 2:00 pm at #OSM2026! We hope you'll join us for our session on Dynamic Coastlines Amidst Changing Sea Levels: Advancements in Understanding the Impacts of Climate Change on Coastal Hazards!

We had a great turn out at our Dynamic Coastlines poster session this afternoon! Looking forward to some excellent talks in our session tomorrow. If you're at #OSM2026, we hope you'll join us from 2:00-3:30 for more discussions on coastal climate impacts!

Hey #OSM2026! We hope you'll stop by the first of our "Dynamic Coastlines" sessions this afternoon in the poster hall. We're roughly between boards 815-863. Hope to see you there to talk about coastal climate change impacts!

Nice story in Science on important new research from Lauren Lewright and colleagues, exploring sea level fall around Greenland As Greenland loses ice, global sea levels will rise—and its own will fall | Science | AAAS share.google/fPwiWMjiCFkP...

We had a great turnout at for the first of our Dynamic Coastlines sessions yesterday—hope to see lots of you back for our posters today! #AGU2025

Happening now at #AGU2025! Come out and join us for a great discussion on coastlines in a changing climate!

Coming up in about an hour, we'll be convening our session on Dynamic Coastlines amid Changing Sea Levels at #AGU2025! Please come by and join us—we've got a fantastic line up! share.google/5FeGmVVjw1vj...

If you care about understanding our atmosphere and the way that it impacts our daily lives—from extreme weather to climate change to air quality—you care about @ncar-ucar.bsky.social

Great to catch up with colleagues at AGU in New Orleans!

Excited to see our updated report on New Jersey's Rising Seas and Changing Coastal Storms get published! In addition to new sea level estimates, we highlight changes to coastal storms— including greater intensity and more precipitation—that amplify coastal hazards in NJ share.google/hn924C30ryP6...

i do not believe for a second that the hundreds of thousands of layoffs we’re seeing right now are bc ai is replacing them, seems much more likely that the economy is imploding along with corporate mismanagement

Important piece covering the ways in which warm ocean waters--made more likely by human activity--contributed to the catastrophic impacts we're seeing from #Melissa.

892mb, 185mph. You can spend your career doing work that shows we should expect more dangerous storms in a warmer climate... But it never gets less mind-blowing or heartbreaking to watch something like this unfold.

Finally, an independent expert, political economist @blairfix.bsky.social, has actually taken a look under the hood, digging deep into the details of Roger's methodology, and it's not pretty. Blair's commentary speaks for itself: economicsfromthetopdown.com/2025/10/26/r...

The human and social impacts of #Melissa are almost certain to be beyond devastating.

In my 30 years being a professional meteorologist, I can't say I have ever seen a #Hurricane with better/ more textbook structure than #Melissa in the Atlantic. It's been a Cat 5 all day long with no signs of getting any weaker. That's a rare run! Here's more...

Happy to have provided input for this well-written story by @laurenthal.bsky.social, highlighting some of the reasons to be concerned about #Melissa, and some of the ways that storms like this are becoming more dangerous in a warmer climate: share.google/96AvQEWmomwa...

For only the second time in recorded history, an Atlantic season has produced three Category 5 hurricanes... the previous year was 2005. This puts 2025 in an elite class of hurricane seasons. It also means that nearly 7% of all known Category 5 hurricanes have occurred just in this year. #Melissa

Changes we expect to hurricanes in a warmer climate include more rapid strengthening, slower forward movement, and more torrential rainfall--all characteristics that describe the incredibly dangerous #Melissa. If you know anyone in Jamaica, please make sure they get to safety.

Really glad to hear that @climatecentral.org has been working to revive and maintain the incredibly important "Billion Dollar Climate and Weather Disasters" dataset, as we continue to see human-caused warming making these disasters more costly and dangerous: www.nytimes.com/2025/10/22/c...

One of the findings from our 2024 manuscript assessing changes in tropical cyclone tracks near Southeast Asia was that, in a warmer climate, it becomes more common for these kinds of storms to impact Alaskan coastlines: share.google/pko58Q42M0lZ...

On The Climate Brink: More about the DOE Climate Working Group report. The Fix Is In: Without independent review editors, their “peer review” process is a sham. Science and humanity deserves better.

Some energy/climate math for the late night crowd: Total Absorbed Solar Energy: 240 W/m2 Total human primary energy use in 2024: 186kTWh (from ourworldindata.org/energy-produ...) Converting: 186*10^15/5.1x10^14/3600= 0.1 W/m2 => total energy from solar is 2400 times what we use.

Our 400+ page comment on the DOE climate working group report is now out. Our conclusion: The merchants of doubt are back, and they're coming for climate science.

On The Climate Brink, I write about the DOE report and our response.

Glad to have been able to take part in this important effort, and to work with colleagues to provide a response to the DOE Climate Working Group report's sea level and tropical cyclone sections, in particular. Many thanks to @andrewdessler.com and @bobkopp.net for helping to organize this effort!

This radar loop of Hurricane #Katrina in 2005 spans August 28 at noon (CDT) through the morning of the 29th at 8:54am when communication with the radar was lost.

Proud to have helped out with this enormous effort. Say it louder for the people in the back: "The amount of energy needed to refute bullshit is an order of magnitude bigger than that needed to produce it."

Really nice piece in @agu.org's Earth's Future a few days ago, showing excellent agreement between satellite observations of sea level in recent decades and the sea level projections from the IPCC's Second Assessment report 30 years ago. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

The only hurricanes in the satellite era with pressures as low as Erin's but below Category 3 winds are Maria (2017), Irma (2017), Sandy (2012), Igor (2010), and Gloria (1985). Erin in ultra-elite company as far as large, powerful hurricanes go. Spectacular sight on satellite.

The center of #HurricaneErin might not make landfall in the US, but its size, strength, and proximity to the coast mean it will still have impacts, including dangerous rip currents along most of the East coast for the next few days. Heed warnings at your local beaches if you're headed to the shore!

Public debate on global warming? Sweet. Let’s also debate the Ptolemaic model of the heavens.
