Unexpected decline in the ocean carbon sink under record-high sea surface temperatures in 2023 - Nature Climate Change The ocean carbon sink strengthened in previous warm El Niño years due to reduced CO2 outgassing in the tropics. Here the authors show that the ocean carbon sink declined in 2023 despite record-high se...

🌊 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. 👇

📝 New preprint out!
We investigated how the marine biological carbon pump is spatially redistributing carbon, even as its global strength stays constant.

New research from MIT found that those who used ChatGPT can’t remember any of the content of their essays.

Key takeaway: the product doesn’t suffer, but the process does. And when it comes to essays, the process *is* how they learn.

A horizontal bar chart titled "Percentage of Global fossil fuel emissions (since 1751) occurring in my lifetime." The chart shows how much of the total historical global fossil fuel emissions have occurred within the lifetime of individuals of different ages, from 5 to 100 years old. The vertical axis on the left lists ages in increments of 5 years, from age 5 at the top to age 100 at the bottom. The horizontal axis represents the percentage of fossil fuel emissions, marked in 10% increments from 10% to 90%. The black bars represent the proportion of fossil fuel emissions that have occurred during each age group's lifetime. The bars increase in length as the age increases, meaning older individuals have lived through a larger percentage of the cumulative emissions since 1751. Three specific age groups are highlighted with red bars and white text annotations: Age 30: "if you are 30 it is more than 50%" Age 50: "if you are 50 it is about 75%" Age 85: "if you are 85 it is about 90%" The source of the data is cited at the bottom: "CDIAC and globalcarbonproject.org." The graphic is credited to "@neilrkaye."

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.

Wo wir leben - Dorf, Stadt, Kleinstadt oder Metropole - werden die Veränderungen von Umwelt und Natur direkt spürbar. Starke Stimmen aus den Kommunen sind notwendig - für Klimaanpassung wie für Klimaschutz.

According to this plot and associated thread, satellites already in orbit, providing invaluable views of our ocean and earth will be turned off. Future missions almost uniformly cancelled. It’s almost too destructively insane to believe true. 🌊

The tragic landslide in Blatten gives me the excuse to tell you the story of how we found out Ice Ages existed. It's a cool story and the most important bit is rather similar to what's happening now.

🌊 With all the changes at NSF and the plan to slash funding by half, I'm thinking of UNOLS all the time. What happens to our world class ocean research fleet without a Division of Ocean Sciences? What will it mean for seagoing research with half the funding?

Despite 150+ years of Radiolaria diversity research, we have just scratched the surface. Nearly half of Radiolaria diversity might be naked hiding in plain sight! We unveiled the diversity and evolution of Radiolaria beyond "the stars of the ocean"
