A new study led by @swri.org provides evidence that liquid nitrogen is rising to Pluto’s surface through cracks in the northern edge of the Sputnik Planitia, part of the massive heart-shaped glacier on the dwarf planet’s surface. 🧪 🔭

Kyushu U today to give a talk at the Center for Oceanic and Atmospheric Research (COAR), RIAM. Very happily my visit coincides with peak Sakura! Here’s my gracious host Prof Toshi Takemura showing all the beauty.

Aerosols are very small, have a high surface to volume ratio and can readily reach super saturation. This combination makes them a unique environment for chemical reactions. We had a paper published in JACS that looked into the rate of chemical reactions within and on aerosols.

👏 Heroic effort to extract a H₂ record from ice cores 👏

The samples had to measured in the field immediately after drilling (i.e. fresh out the oven 🥮) to prevent the tiny H₂ molecules from leaking out.

Having a great day at JAMSTEC, visiting the Earth Surface System division. Their lobby has former versions of the Earth Simulator computer (currently at version 4) and, nerd that I am, here is a photo. JAMSTEC also lead work on LLM for climate adaption planning - essopenarchive.org/users/555101...

Fascinating new paper in PNAS on tropical cyclones from researchers in 🇹🇼 based on "a typhoon series for 1368–1911 reconstructed from Chinese historical documents digitized in the REACHES database". The use of records in archival texts is new to me and, again, 🤯. www.pnas.org/doi/10.1073/...

Bit late with this one, and paywalled. Fascinating to see AI tool concluding >20% of peer-reviews for ICLR are wholly AI-generated. Wait to see if there was a strong difference between the conclusions of the reviews, although it does flag some egregiously bad cases. www.nature.com/articles/d41...

Super pollutants are trendy, but we should be careful how we use them • Substituting short lived climate pollutants like methane for CO2 as carbon offsets risks breaking the math of net zero
