I’m a climate scientist. Let me fix this headline. “Nearly a century ago, scientists showed that burning fossil fuels warms the planet. Today, we know human emissions account for over 100% of the warming. Yet dark money and disinformation still work to keep Americans addicted to fossil fuels.”

“Whales, all along, were writing a life history journal in their bodies, only we didn’t know how to read it,” says Kathleen Hunt. My latest @nature.com story. Many thx to Dr. Hunt, now at Oregon State University's Marine Mammal Institute, and others for their time and insights.

🌊 The ocean absorbs >90% of Earth’s excess heat, and our ability to track it depends on a fragile global network of floats, ships and sensors. New research warns that cuts to the Global Ocean Observing System could make climate signals indistinguishable from noise. www.nature.com/articles/s41...

The % of scientists who think public engagement makes science better has gone up from 21% in 2006 to 64% now. That's huge.

Certaines réponses au fil de Dietterich sont effarantes, venant de la part de chercheurs (tl,dr : je ne vérifie pas les citations, c'est une perte de temps, j'écris des centaines de papiers). Quand on dit que l'AI générative peut entraîner un effondrement de la recherche, le risque me paraît réel...

For those who reached out asking how to help: This gofundme is specifically for graduate students who lost personal items, computers, tablets, etc. in the fire. We were told that these items are not retrievable or reimbursable -an added burden for students during a devastating time. Plz share 🌊💙

Yep. Bluesky isn't Twitter and might never replace it, but it still has many merits of earlier Twitter - such as good insights by academics, experts, & journalists, actually constructive comments, and occasional memes.

🌊🧪 Marine snow particles sinking from the surface ocean are critical for deep sea food webs and the oceanic carbon cycle. How fast they sink determines how much carbon reaches the deep ocean, but measuring their speed directly in the field is a challenge in oceanography.

Big sea surface temperature departures remained in the Labrador Sea for March 2026. Most ocean areas were warmer than average last month around the ice park, though cooler anomalies expanded in the eastern Bering Sea and Gulf of Alaska regions.

🧵🧪❄️🌊As today is UN World Day for Glaciers I'm taking the opportunity to post this reminder that the main reason nobody can confidently predict how much sea-level will rise over the rest of this century and beyond is "deep uncertainty in ice sheet processes" (IPPC AR6). #WorldDayOfGlaciers #Sealevel

We don't know what's happening, but there's no good news here. As long as we keep burning fossil fuels, the world will continue to become more dangerous and chaotic.

A bitter day for the fight against climate change. The decision by the International Maritime Organization (IMO) to postpone the decision on the climate protection pathway for global shipping by one year is wrong. Countries may be able to be pressured, but the planet cannot.

The Alaska Native village of Kipnuk was due to receive a $20M grant from the EPA that they were going to use for flood protection. It was labelled “wasteful DEI spending” and canceled. The recent storm destroyed homes & flooded Kipnuk: www.nytimes.com/2025/10/14/c...

As a primatologist, Jane Goodall was a huge inspiration to me. I admired the way she describes chimpanzee behavior with such detail and empathy, and she’s inspired so many people and advocated for chimpanzee conservation and welfare. However, I'm dismayed at what her narrative leaves out (1/10)

“Among the many [proposed] deep cuts to scientific research…is the abrupt termination of the Nathaniel B. Palmer, the sole U.S. icebreaker dedicated to Antarctic research. The budget also pauses development of a new vessel that was supposed to succeed the Palmer in the 2030s.” [gift link]

Well, here's some good news to start the weekend. Negotiating a treaty is one thing, but the work only starts once it's ratified and it looks as though the High Seas Treaty (aka BBNJ) will soon be up and running. This provides structure & standards & is a big step in protecting our ocean. 🎉🎉🌊

I collected this beautiful acantharian cell into an intermediate dish knowing it was getting ready to swarm... but by the time I returned to it to transfer it to an individual well it had already started to release swarmers. So, I just captured the end of the process. Enjoy! #protistsonsky 🦑
