We got out for our first ski of the season this morning.

Santa’s identity has been shaped by the state our Union. Another incredible piece by @hcrichardson.bsky.social.

Santa was just spotted in Augusta, Maine! Already in Quebec. I should get to bed and hope that he is kind enough to swing back our way…

For this #fieldphotofriday, I share a photograph of Pia fjord, Cordillera Darwin, southern Patagonia, 2012. I was very fortunate to work here with Brenda Hall, Tom Lowell, George Denton, and the late Charlie Porter. Our paper on the chronology of rapid deglaciation is now published. Link follows…1/

Dear Santa . . .

Happy winter soltice to my friends in the Northern Hemisphere, and Happy summer solstice to my friends in the Southern Hemisphere. Looking forward to celebrating Perihelion on January 3rd!

Happy Solstice to all. Next stop: Perihelion.

Some scenes from NOLA this week… 1/

A Lord of the Rings cover band called The Grateful Dead Marshes.

Maine is getting blasted by warm, moisture-laden southerly winds transporting heat from near the tropical Atlantic. …not too different from the sou’easters from this time last year. Snowpack has been obliterated. 🧪🌊❄️🥼⚒️

While NCAR employees are not federal employees, almost all of its budget comes from the federal government. If you pay taxes in the US, NCAR's research belongs to you. Russ Vought doesn't have the unilateral right to cancel congressionally appropriated funds.

I know many of you who follow me don't work in climate science, but this is the biggest story in climate right now. Breaking up NCAR makes us all less safe and is another act of self-harm that will take decades to recover from.

This story in Science gives a lot of space to the alleged justifications for these changes, with lengthy quotes criticizing panels for "group think" and implying that rotators from academia limit NSF's ability to align with the administration's prioities www.science.org/content/arti...

The temperature at the Juneau Intl Airport dropped to -2F yesterday. This is only the 4th sub-0F day there in 15 years. Prior to the 1980s, it used to happen about 10 days per year. @alaska.bsky.social @alaskawx.bsky.social

New paper alert! 🚨 🐌 We studied historic Antarctic fossils from the Zinsmeister Collection to assess whether the K-Pg extinction, as recorded on Seymour Island, was sudden or gradual. We found that benthic life thrived in the 4 million years before the K-Pg. doi.org/10.1016/j.pa...

Whatever the weather on deck, it's always a good day inside the Burren.

A fantastic Maine Calling on @mainepublic.org today with Simon Winchester talking about the history and the future of the wind! Highly recommend. His latest book is “The Breath of the Gods: The History and Future of the Wind”.

Attention all Subantarctic Mode Water enthusiasts ☺️; check out this lovely new paper led by Zhi Li with Sjoerd Groeskamp, @alexhaumann.bsky.social Ivana Cerovečki and Lynne Talley; exploring propagating signals of SAMW anomalies tracing their origins to the tropics. doi.org/10.1175/JCLI...

This is one of my favourite space photos. It's Pluto, backlit by the Sun, imaged by NASA's New Horizons spacecraft in 2015. Look carefully and you can see the planet's irregular topography and the layering in its atmosphere. Credit: NASA/JHU APL/SwRI

Harvested the carrots this morning.

I wanted to share probably the most important sermon I’ve given and it’s while I’m being arrested. It’s torture pure and simple what happens at #Broadview. I’m ok, though I was thrown to the ground and choked with my pectoral cross. A review of the video shows I was peaceful - did I deserve this?

Very cool to see the ferries in my hometown of BC are going electric! 👏🏽👏🏽👏🏽

This is great piece by Nadir Jeevanjee (NOAA GFDL) that summarizes five of the fundamental and accurate model-based climate predictions made by Suki Manabe and colleagues at GFDL over the past half century+. 🧪⚒️ theconversation.com/5-forecasts-...

Seems like the #Aurora is already visible over a large chunk of the CONUS tonight thanks to the #CME's over the last few days from a couple of significant X-class solar flares.

Just out: new New Jersey state sea-level rise assessment Under current global emissions trends, New Jersey is likely to experience 1.5-2.5 ft of sea-level rise between 2005 and 2070, 2.2-3.8 ft by 2100 (or 2.2-4.5 ft, considering potential ice-sheet collapse).

It's v hard to tell but it might be Didal Glacier, which is surge-type and actually was surging in the months prior to this video. I don't know if something switched allowing the runaway mode seen in the video. Curious for thoughts of other glaciologists 🧪⚒️❄️ www.planet.com/stories/dida...
