In the Department of Earth and Environmental Sciences @columbiauniversity.bsky.social, we are hiring an Assistant Professor in Atmosphere and/or Ocean Physics. No deadline stated, but review will begin soon, so please do not delay. apply.interfolio.com/173819

So nice to see #Polarstern pCO₂ data from the @awi.de MOSAiC expedition being used to provide better quantifications of Arctic Ocean CO₂ uptake. 🌊 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

🌊 In 2023, the ocean carbon sink weakened for the first time in a record-hot year 🌡️🌎 Our new study in Nature Climate Change quantifies this unexpected decline and explains how it came about. 👇 doi.org/10.1038/s415...

My latest: Polar scientists warn that the White House and NSF are planning to terminate the Nathaniel Palmer, the only US research icebreaker capable of handling Antarctic extremes, this October. So far the plan has seen minimal pushback from Congress.

🌊❄️🧪 🇦🇶 Please share: We have learned that the National Science Foundation is moving ahead with plans to decommission the U.S. Research Vessel/Ice Breaker Nathaniel B. Palmer this October. If you care about Antarctic research, please read on (1/n)

They want to close the NOAA lab (GML) that brings you this, the most iconic time series in the environmental sciences. gml.noaa.gov/ccgg/trends/

AI has greatly accelerated my transition from Matlab to Python. But 3 experiences *this week* have alerted me to the potential for mistakes and brain rot when getting too reliant. First, I used it to help me write code to compute lagged correlations between two variables. 🌊🧵1/4

📢 New paper alert! 📢 New insight into how sea ice controls the ocean uptake of carbon dioxide around Antarctica, obtained from the unique year-round Rothera Time Series. Delighted to be part of this study, led by the very excellent Elise Droste. 🧪❄️🥼🌊 www.nature.com/articles/s43...

On this day 40 years ago, the Schengen agreement was signed, paving the way for free movement across Europe without internal checks. Today, 3.5 million Europeans from 29 countries are travelling, working, and moving freely across Europe on a daily basis. 🔗Learn more: europa.eu/!6QwJvb

Happy to share our paper in ‪@science.org‬ 'Observed trend in Earth energy imbalance may provide a constraint for low climate sensitivity models' | Science www.science.org/doi/10.1126/...

Liqing Jiang led a new synthesis project for ocean carbonate chemistry data sets which is now in review. 🧪🌊🦑🌐 Check out the preprint! 👇 doi.org/10.5194/essd...

After working at it for a while, I finally convinced @clequere.bsky.social to join Bluesky. Many of you know her, but if not, she’s an extraordinary scientist whose impact on climate science and society is hard to measure. Please give her a follow. research-portal.uea.ac.uk/en/persons/c...

SOCAT v2025 is released today! A grand total of 49.6 million surface ocean fCO2 observations from dozens of contributors around the world. www.socat.info/v2025 #ocean #co2

#NeverAgain I visited Auschwitz as a teenager during a school exchange program with Poland. It was one of the most intense experiences in my life - I will not forget. Everyone should visit, really. Thank you for your work, @auschwitzmemorial.bsky.social

I've been working on ecological responses to environmental change for a long time, so I enjoyed putting down my thoughts (and code!) on how best to go about analysing response curve/reaction norm experiments. I think you'll find it useful if you do these kinds of experiments (and maybe otherwise!)

Well, fuck! Just got a message from my university that we can no longer spend money on our NSF-funded grants. This is as good as having the grants taken away from us.

Das kann nur heißen: Keine Zusammenarbeit in Bund, Ländern und Kommunen, erst recht keine Koalitionen. Wehren wir uns gegen die Feinde unserer Verfassung. Die Bundesregierung und/oder der Bundestag sollten das Verbot betreiben. www.tagesschau.de/inland/innen...

It is the last day of #EGU25, here is a highlight that makes use of REcoM's variable stoichiometry in an Earth System Model configuration. Don't miss it !

Today at #EGU25:

The Warming Stripes have now been extended downwards into the ocean and upwards into the stratosphere! Collaborative paper which tells the story of how the stripes were developed, and discusses their extension across the Earth system, is now available in BAMS: journals.ametsoc.org/view/journal...

And more on the ocean carbon sink #GCB, Monday morning, room C 11:35–11:55 Jens Müller The ocean carbon sink under record-high sea surface temperatures in 2023/24 11:55–12:05 Alizée Roobaert SOCOMv2: On the strengths and limits of pCO2 interpolations products to estimate the ocean carbon sink

#EGU25 presentations of the marine biogeochemical modelling group @awi.de are starting with the Monday morning presentation of Frauke Bunsen Assessing the recent ocean carbon sink with data assimilation into a global ocean biogeochemistry model Monday, 11:25–11:35, room C

🌡️ 2023 sea surface temperatures reached record highs — but what does that mean for the #ocean’s #carbon uptake?🌊 At #EGU25 today, Dr. Jens Müller (@jens-d-mueller.bsky.social) is sharing his insight on this critical question in a 20-min presentation 📍 Room C 📅 11:35 Don't miss out! #ClimateChange

New book!! 📕 Antarctica is intimately connected to the rest of our planet, affecting climate, ecosystems, cultures and society. Our new book draws together international experts to explore this influence, and to understand what humans are doing to Antarctica (1/n) www.routledge.com/Antarctica-a...

🌊 nice opportunity for a research fellow in a coordinated modelling project

@icbm-uol.bsky.social offers a fully funded professorship in theoretical oceanography. Join a great team of physicists, chemists, and biologists working on the marine environment. Oldenburg is a truly livable city and connected to a range of marine institutes in NW Germany uol.de/en/job/w2-pr...

Can the UNFCCC or @unep.org take on the #ManuaLoa monitoring? I would definitely donate to a kickstarter/gofundme campaign The madness of questioning the value of long term scientific monitoring is a special form of insanity 🧪⚒️🌍

The people who produce this Mauna Loa atmospheric CO₂ record have a lab in Hilo, Hawaiʻi, about 50 miles (80 km) from the observatory. By closing the lab, it'll be really difficult to maintain the CO₂ observations.

Hier gibt's einen tollen Science Slam von @miriamseif.bsky.social über Carl das Kohlenstoffatom und biogeochemische Modellierung. Vielleicht möchtet Ihr mal reingucken, es lohnt sich! Los geht's ab eta 41:14 - die anderen Slams sind bestimmt auch gut ;) www.youtube.com/watch?v=EyFl... 🌊🧪@awi.de

One of the people fired from NOAA today is the director of the Ocean Acidification Program. That program also leads the U.S. government's effort on marine carbon dioxide removal (mCDR). The destruction of American science is incomprehensible.

Ob Solarstrom, E-Autos oder Batteriespeicher: die weltweite Klimawende läuft exponentiell. Ein Sonderweg Deutschlands ist das definitiv nicht - eher im Gegenteil: durch zu langes Festhalten an Verbrennung in Autos, Kraftwerken und Heizungen drohen wir abgehängt zu werden.
