Check this nice first first-author paper by Ning Hall—now out in Nature Geoscience! Our team had a blast supporting Ning on the isolation workflow, and a few of the standout Methanococcoides strains even trace back to our Danish waters. 🌊 www.nature.com/articles/s41...

Hearing state officials talk about how unexpected these floods were & it’s infuriating. This was completely predictable to anyone even vaguely aware of the climate crisis. Same thing with LA fires. The Mayor cut the fire fighting budget as global temps soared. Climate ignorance = needless deaths

To the non-expert, this will seem esoteric, so allow me to summarise: we have profoundly altered the distribution of nutient elements on the ocean, with a potentially profound impact on the life that lives in it.

One might expect that climate mitigation measures would help to counteract oxygen decline in the oceans. Yet a new study reveals that many proposed marine carbon dioxide removal methods could in fact intensify oxygen loss. 😕 🌊 Read more: www.ru.nl/en/research/... with @carolineslomp.bsky.social

Our study just out in Nature: the extreme North Atlantic heat in summer 2023 was mainly due to weak winds causing shallow mixed layers, which heat up more quickly. Global warming is causing a trend toward shallow mixed layers, making such extremes more likely. 🌊 www.nature.com/articles/s41...

The US, UK, and The Netherlands are all gutting their excellent and very international higher ed systems, through budget cuts and nativist language. Short-sighted impulse politics that will cost money and soft power. And a huge opportunity for other countries to increase theirs…

Bacteria may have adapted to oxygen well before Earth’s atmosphere was saturated with it, according to a new study in Science. The findings underscore the dynamic relationship between biological evolution and Earth's geological history. scim.ag/3YpwMyu

Research and higher education in the Netherlands is under severe threat from short-sighted government budget cuts. This damage will have long-lasting repercussions... A sad day for science 😢 nltimes.nl/2025/04/08/s...

En als je deze expertise kwijt bent, dan kan je die later niet zomaar weer terughalen… waarom bepalen de keuzes van 18-jarigen waar onderzoek naar wordt gedaan?

Due to massive budget cuts, my university @vuamsterdam.bsky.social plans to cut its Earth Sciences bachelor (+ the Earth Sciences department). 37 staff members lose their jobs, and valuable research disappears. This is just the beginning: all Dutch universities are bracing for deep cuts.

Just in case you want to move to the Netherlands:🧪🔭 (read the article, it's actually kind of problematic after the biggest cuts in science funding here in 40 years, but hey, thought I'd let you know anyway!) www.dutchnews.nl/2025/03/dutc...

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.

Dutch universities go on strike - for the first time since anyone can remember. We protest the treatment and budget cuts of our extreme-right government. The strikers take turns - and Leiden university kicks off tomorrow. ✊🏼

Congrats to Niels van Helmond! Really happy that this work on vanadium as a redox proxy is now out! Be careful when assuming that anoxia always leads to vanadium enrichments in marine sediments…..

You might think you're heroic for quitting Twitter, but this is next level. To be elected a Fellow of the Royal Society (FRS) is one of the highest honors in science. @deevybee.bsky.social gave up her FRS because she didn't want to be associated with Elon Musk, who was elected FRS for space stuff. 👏
