☀️🌧️ Extreme weather events are increasing 🌀🌤 Our new paper discusses the range of extreme weather attribution methods available and how we should be combining them to improve confidence in our attribution statements with co-authors: @marylouathanase.bsky.social & Shirin Ermis doi.org/10.1002/wea....

If you want to learn more about Storylines of Marine Heatwaves, my #OOSC presentation starts today at 16h30 🌊

To celebrate the kick-off of #UNOC3 and #OOSC in Nice, we share a striking, mesmerising perspective on Mediterranean Marine Heatwaves —and their clear amplification by climate change. From @awi.de storyline simulations, visual by @jawijan.bsky.social

So it begins. Day 1 (of 2) of traveling to #OOSC & #UNOC3 in Nice by train, all the way from Northern Germany 🚝 Looking forward to meet some of you there!

A little belated post to share the latest article by Wenqin Zhuo together with our @awi.de team of "storyliners"! This time investigating cold extremes. Read in @natureportfolio.nature.com: doi.org/10.1038/s416...

Our paper on the Arctic Beaufort Gyre in CMIP6 is featured in a spotlight article 🌊 *And* it is now #9 largest score on @altmetric.com of all @jgroceans.bsky.social articles... What a week Read on @eos.org: eos.org/research-spo... W/ @raphaelkoehler.bsky.social and @clnhz.bsky.social

⬆️New research by @marylouathanase.bsky.social & @raphaelkoehler.bsky.social of @awi.de, @clnhz.bsky.social, + colleagues in @jgroceans.bsky.social.

Climate models offer little clarity on how climate change will affect the Beaufort Gyre, an influential current in the Arctic Ocean. Most predict the current will weaken or even stop, but the timing and impacts of this fate remain uncertain. eos.org/research-spo...

C’est l’un des nombreux bouleversements entraînés par la disparition de la banquise : elle change la couleur des océans Arctique et Antarctique. De quoi entraîner des conséquences « considérables » pour certains organismes marins comme les algues et le phytoplancton www.lemonde.fr/planete/arti...

Starting at 12:45 at #EGU25 Bring your lunch!

Coming up soon at #EGU25, come along to chat about event attribution at lunchtime in room 2.43

Une nouvelle étude intéressante et qui va au-delà des effets d'annonce. Le nombre de papier devient conséquent sur le rôle de la variabilité interne. J’ai pu l’expliquer sur @franceculture.fr merci à @alexandremorales.bsky.social www.radiofrance.fr/francecultur...

I will be presenting our results at #EGU25 in a poster on Wednesday. 🌀 So if you'd like to chat about the Arctic Beaufort Gyre in CMIP6 models, find me there! The poster: meetingorganizer.copernicus.org/EGU25/EGU25-... The paper: agupubs.onlinelibrary.wiley.com/doi/full/10....

If you are attending #EGU25 and interested in the attribution of #climate extremes: consider joining our networking session on Friday noon! We will exchange on existing methods, their strengths, and how to compare them: meetingorganizer.copernicus.org/EGU25/sessio... W/ @vikkithompson.bsky.social

Our article is out in @eurogeosciences.bsky.social's GMD journal, on global multi-year kilometre-scale modelling with @ecmwf.bsky.social’s IFS coupled to FESOM2.5 (finer than 5km). See the paper here: doi.org/10.5194/gmd-... This is what we found: (🧵1/n)

🆕 from PolarRES' @raphaelkoehler.bsky.social & colleagues on the future of the Beaufort Gyre, a major Arctic Ocean current. By accumulating/releasing freshwater, it shapes ocean properties. But most CMIP6 models project it will weaken or vanish, disrupting ocean circulation. 🔗: bit.ly/4cdZo3m

New study led by @marylouathanase.bsky.social and @raphaelkoehler.bsky.social. As #SeaIce thins, the Beaufort Gyre releases its feshwater out of the #Arctic. We don't predict the "Day After Tomorrow" but I'm curious about potential impacts on the #AMOC agupubs.onlinelibrary.wiley.com/doi/full/10....

Fantastic to see this by @marylou_athanase @raphaelkoehler.bsky.social @clnhz.bsky.social et al out - an @PolarRES inspired project started at our very first bootcamp with @clicwcrp.bsky.social #norp way back in 2022 https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2024JC021873

Our new study is out: The Arctic Beaufort Gyre is projected to weaken or vanish in most CMIP6 models under future climate change. The gyre would thus stop storing freshwater in its centre, with possibly large impacts on the Arctic and beyond. Read: agupubs.onlinelibrary.wiley.com/doi/full/10....

Planning your #EGU25 travel? If you're interested in extreme event attribution, make sure to stay until Friday to come along to our networking session to discuss the value of multiple methods. @marylouathanase.bsky.social

This is really sad news. NOAA GFDL is one of the world's leading climate modeling centers, home to exceptional scientists. If anyone directly affected needs support, I’m happy to help. www.science.org/content/arti...

This is absolutely devastating. "The University of Maine System, which oversees Maine Sea Grant, said it was notified Friday night that NOAA was terminating a four-year agreement for funding, leaving 20 employees and the Sea Grant’s programming in limbo." www.pressherald.com/2025/03/01/m...

Hi - I'd like to share this story of what is happening at NOAA GFDL, where some of my colleagues and I worked until the mass firings at NOAA last week. "...the birthplace of weather and climate forecasting"
