New Job! Please RP! 2 year Postdoctoral Research Associate in #Biogeochemistry in Oxford @oxfordgeography.bsky.social using novel methods to explore organic matter stability and new proxies of rock #weathering &wider team in Southampton. Any Qs let me know 🧪🥼⚒️ my.corehr.com/pls/uoxrecru...

One-third of growth-season rainfall in the Amazon comes from evaporation from trees. When forests are cleared for soybeans, rainfall declines, potentially reducing soybean yields and creating a feedback loop that could drive further land clearance. In PNAS: https://ow.ly/2TlF50ZbTqf

I really enjoyed collaborating on this study lead by Laura Summerauer (now @ FiBL) that showed rapid degradation of soils following deforestation in Eastern Congo. Corroborates what we observed measuring DOC age in rivers draining the same impacted landscapes. bg.copernicus.org/articles/23/...

👀 Organic carbon weathering as an amplifier of climate warming 183 million years ago: “Weathering of sedimentary carbon-bearing rocks, such as shales, can emit significant quantities of CO2, causing temperatures to rise and further weathering to occur” ⚒️🧪 www.earth.ox.ac.uk/article/not-...

Kick off your morning with a very nice write up in Mongabay about our recent Lac Mai paper. @johansix.bsky.social @jordonhemingway.bsky.social @saegroupethz.bsky.social

Reminder, three more days to apply for our *two* fully funded PhD positions on tropical African biogeochemistry! @eth-eaps.bsky.social @usyseth.bsky.social @draketw.bsky.social @johansix.bsky.social

Ryan (and me) are hiring a PhD student! Sweden is a great country to do a PhD, see the link or ask us for more details, or share with potential students!

Two major humic lakes in the Congo Basin are emitting ancient carbon from nearby peatlands into the atmosphere, reports a study in Nature Geoscience. These findings challenge the prevailing understanding that CO2 emissions from pristine humic lakes are derived from modern, rapidly cycling carbon. 🌍🧪

New job! Please RP! 🥼🧪 ⚒️ Laboratory Manager (gr8, permanent) @oxfordgeography.bsky.social Leading the Geolabs, with cutting edge facilities in water #geochemistry, #ecosystem science, #eDNA, luminescence Apply by 13 March or please get in touch with any Qs my.corehr.com/pls/uoxrecru...

Very happy to see our @agu.org @jgrbiogeo.bsky.social paper on greenhouse gas emissions from Congo lakes published! Following up from @draketw.bsky.social's companion paper last week. With @johansix.bsky.social et al. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Congo Basin blackwater lakes release ancient peat carbon—challenging long‑held climate assumptions. Land‑use change may worsen this trend.🚨🌍Research by @draketw.bsky.social and colleagues. #ClimateResearch #ETHZurich #Peatlands #CongoBasin ethz.ch/en/news-and-...

Nice presser on our new paper by ETH. ethz.ch/en/news-and-...

New paper alert! 🚨 Our new study shows that massive lakes in the Congo Basin are outgassing millennial-aged carbon. This challenges the idea that lake CO₂ only comes from modern vegetation. www.nature.com/articles/s41... Thread below! 🧵👇

Final EIA-860 is out, and 2025 really did it: 54 GW of new U.S. electric capacity, 96% clean. Solar again carries the offense, and we built more storage in 2025 than the cumulative total through 2023. More and more and more additions... but also record low retirements.

Very excited to announce *TWO* fully-funded PhD positions starting this summer focusing on greenhouse gases in the peatlands of the Congo Basin! Both positions are joint between my group in @eth-eaps.bsky.social and that of @johansix.bsky.social @usyseth.bsky.social. Come join us!

We need greater reward for primary research, often labor intensive and often done by small groups, and less reward for large multi-author review papers. 3/2

Here we go again!!! 🇨🇩

Like anything by Hannah @hannahritchie.bsky.social, I'm sure this is worth reading: www.theguardian.com/books/2025/s...

If you think climate change has gotten worse during your lifetime, you're right and there's a good reason. If you're Gen X like me, more than 3/4 of fossil fuel CO₂ emissions have occurred in your lifetime. Even if you're a Millennial, it's at least half. 📊: @neilrkaye.bsky.social

In this new commentary for The Conversation Africa, @johansix.bsky.social, Matti Barthel, Glenn Bush, and I discuss what the new "green corridor" law means for the Congo Basin and what might impede its success @saegroupethz.bsky.social @usyseth.bsky.social theconversation.com/drcs-plan-fo...

How does #biodiversity control 🍂decomposition in #RiverNetworks? In our new Ecological Monographs paper, we show that 🪲macroinvertebrate key taxa drive decomposition, while #FunctionalDiversity reduces decomposition #variability! Network-scale #BEF in action, check it out! doi.org/10.1002/ecm....

Looking the get the most out of your stream CO2 data? Check out the coupled O2-CO2 model developed by Jake Diamond and me, out today in JGRB! The model extends the single-station O2 model by coupling DIC mass balance and carbonate buffering. agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Cool! Our Ruki paper was the top viewed article at L&O @aslo.org! 🎉 @johansix.bsky.social @saegroupethz.bsky.social

Greenhouse Gas Emissions and Lateral Carbon Dynamics at an Eroding Yedoma #Permafrost Site in Siberia (Duvanny Yar) 📄

Latest paper out of the WS hydrology lab! Here we show spatial variability in lithology is important for streamflow behavior and carbon export, but geogenic solute export behavior is similar. agupubs.onlinelibrary.wiley.com/doi/full/10....

Let's just roll the dice, eh?

Switzerland’s glaciers are disappearing fast! Without drastic emission cuts, they could be gone by 2100. Our group head, ETH Prof. Daniel Farinotti, discusses the urgency of action in this interview for the first World Day for Glaciers. 🌍❄️ 🔗 Read more: ethz.ch/en/news-and-...

Fighting continues this morning in several parts of #Goma as further M23 troops move in from western side (and seem to gain ground for now). Ambulances caught in crossfire. In parallel, demonstrators have attacked embassies in #Kinshasa, torching the French & Rwandan premises.

Remembering David Lynch today. When I started watching films by director and came across Blue Velvet, I didn't stop until I'd seen his whole strange, surrealist, and captivating catalog. Such a distinctive, off-kilter perspective that will be missed.

Enjoyed collaborating on this newly published effort! www.sciencedirect.com/science/arti...

Yikes.

Finding reviewers this time of year is a complete joke. Remember folks, everyone is busy and if you submit papers to peer-reviewed journals, at least two people are going to spend their time giving it the consideration it deserves. ✨ Please pay it forward as well when you are asked to review.

%5 increase in global stream power in ~30 years = more erosion potential Interesting that the Congo Basin has shown a downstream shift in flow distribution -> low lying basin with no upstream shifts in precip and minimal human regulation of flows? fun paper!: www.science.org/doi/epdf/10....

Nice write up by ETH news on our Ruki study: ethz.ch/en/news-and-...

Our new study on the carbon biogeochemistry of the pristine blackwater Ruki River, DRC is out! aslopubs.onlinelibrary.wiley.com/doi/full/10.... The Ruki generates ~20% of the Congo's DOC load despite occupying only 5% of its area.
