I am so tired of waking up, reading the news, and writing an email like this to an American colleague: "Dear [insert career civil servant's name], we read the news of [name of closing lab] with a heavy heart this morning. Please don't hesitate to reach out if we can help." The #NCAR news bites.

Trump moves to dismantle major US climate research center in Colorado

The Trump administration is breaking up the National Center for Atmospheric Research, taking aim at one of the world's leading climate research labs.

Here we go again! 🎤 Our event "Diverse minds, shared future", in collaboration with the LGBTQ+ STEM group during the Berlin Science Week, is approaching fast! We're excited to start introducing the amazing speakers joining us for this year's event

The #JuneauIcefield is a deeply meaningful place for me and many others, part of the reason we put so much care into our case study on tipping of Áakʼw Tʼáak Sítʼ (Mendenhall Glacier), one of the icefield's major outlet glaciers. The study is out today as part of the Global Tipping Points Report.

Bleaching, Melting, Slowing: New Global Tipping Points report tracks growing risks of Earth system tipping points. It highlights mounting risks, from melting glaciers, ice fields to slowing ocean currents, ice sheets & rainforests under pressure. www.pik-potsdam.de/en/news/late...

Super stoked to be one of the speakers at this year's #PrideHike in the beautiful Kaisergebirge! I'll be chatting all weekend about the changing alpine environment and how that impacts us ~all~, especially those of us whose happy place is up in the thin air. Thanks to Osprey (packs) Europe for (1/2)

This quote at my SBahn stop hitting differently this week. “What a time it is when talking about trees is almost a crime. Because it involves silence about so many misdeeds!” How I feel coming and going talking about clim. change/Michelangelo, trying to ignore the rising tide in my former home.

Quote in German from Bertolt Brecht translated as: What a time it is when talking about trees is almost a crime. Because it involves silence about so many misdeeds!

Getting a bit teary on the train listening to two elderly gays signing up for new life insurance policies and making each other the beneficiaries. Something really beautiful in the mundanity of that. Speaking a mix of English, Swedish, German, and French. Stunning.

Did a thing last week🎓. Really thought I wouldve left it before that day came tbh. Can remember the moment I was accepted to a PhD, 21, totally gobsmacked. The day I left Boston and that first PhD, my supervisor in the Times for harassing his students in Antarctica. The first time w/ my 🌈 pin(1/2)

Hello world — with little luck, I’m looking for a paper that summarises the history of study of climate change, particularly with respect to glaciers. I.e., what did researchers in the early 20th century think caused the kind of variability that led to terminus position changes? Suggestions?

Just spent the last two weeks crisscrossing the U.S. West with my TIPMIP colleague to talk climate and Earth system tipping points. We’ve learned so much about the state of tipping research in the U.S.! Looking forward to our next stops on the East coast before our TIPMIP General Assembly and AGU!

Happening today at Lettretage in Berlin! Join for a discussion of "The Shining Mountains" by Alix Christie, and a short warm-up reading by yours truly :). Veteranenstr. 21, doors open at 19:00, readings begin 19:30.

pro tip: if you power walk to work listening to an aerobics playlist wearing a beige turtleneck, white high tops, and calvins, you kinda feel like your mom in the eighties which is fun.

Was such a delight to see @katharinehayhoe.com at PIK today 😊. Such a nice discussion on public perceptions of climate change/policies, the role of scientists in enacting climate policy change, and the space science and scientists occupy in political arenas. Thanks for the great talk (as always)!
