Microbes rock 🎸🤘 with sulfide and iron minerals

I am very excited to share our recent study, which describes a previously unknown microbial energy metabolism ⚡⚡⚡🦠🧫⚡⚡⚡

Witnessing the rapid and extensive thawing of permafrost in Svalbard is truly impressive but deeply concerning

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.

⚒️ Article: The proportion of carbon, nitrogen, and phosphorus in the ocean now substantially differs from the Redfield ratio, likely reflecting a reduction in phosphorus limitation

Pieces of fossilized Bryozoan sea mats, like fine lace netting.
Despite their delicate appearance, they have managed to survive intact in these rock layers for over 300 million years.

Now I've had a chance to read Andrea Sella's article in @chemistryworld.com on why he returned his Royal Society Faraday Medal. I recommend that you read it too. It's inspiring, though inevitably also disturbing, in these troubled times.

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.

Review of methane through space and time, coauthored with @planetdr.bsky.social, is out (OA) in @annualreviews.bsky.social.

Hopefully a helpful resource for community and courses. www.annualreviews.org/content/jour...
Schematics of atmospheric CH4 cycling on (a) modern Earth, (b) Archean Earth, and (c) Titan. (a) On modern Earth (20% O2), CH4 emissions originate primarily from wetlands, ruminants, and the fossil fuel industry. Methane is oxidized chemically in the troposphere by hydroxyl radicals (OH), with an average lifetime of 10 years. Hydroxyl radicals originate from reactions between ozone (O3), UV radiation (<320 nm), and H2O vapor. The O3 layer originates from reactions between UV radiation and O2. (b) On the Archean Earth (<0.0001% O2), in the absence of O3 and O2, CH4 would have had a much longer atmospheric lifetime (∼10,000 years), with eventual destruction by UV photolysis, leading to H escape and/or, when CH4/CO2 was greater than 0.1, polymerization to yield organic haze in the upper atmosphere. (c) On Titan, with temperatures near the CH4 triple point, there is a CH4 cycle of evaporation, photolysis to yield ethane (C2H6) and H2 (lost to space), and condensation of C2H6, whereupon it participates in surface processes.

It's worth reading this @thebulletin.org article about preserving the Keeling Curve.

Go deeper: Many scientists have trumpeted the scientific—& even cultural—value of long-standing datasets like this, even suggesting that some deserve World Heritage status to protect them.

I'm on an mCDR panel at #EGU25, but I just learned that our convener Carolin Löscher from Denmark won't be there.

She's been diagnosed with a rare and aggressive form of cancer whose expensive treatment is only available in the US and UAE.

Screenshot of the European Geosciences Union (EGU) General Assembly 2025 website showing the session details for "Session US2 – Marine Carbon Dioxide Removal: Fostering Earth Science Forces for Combating Global Warming." The session is scheduled for Friday, May 2, 2025, from 14:00 to 15:40 CEST in Room E1. It is chaired by Giulia Faucher, Carolin Löscher, and Gerhard Herndl. The program includes a 5-minute introduction, speaker presentations, a discussion on marine carbon dioxide removal (mCDR), and audience questions. Featured speakers are Louis Legendre (France), Daria Atamanchuk (Canada), and David Ho (USA). The session is hybrid with Zoom access. 🌊

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…
