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.
A nice trip to MRI in Tsukuba to attend Stephanie Fiedler’s seminar (and to talk with Stephanie and her host Naga Oshima)
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.
Happy to be at #CMIP26 with my Bristol colleagues. Always amazing to come to the Kokukaisaikan in Kyoto.

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in PNAS on tropical cyclones from researchers in 🇹🇼 based on "a typhoon series for 1368–1911 reconstructed from Chinese historical documents digitized in the REACHES database".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...
Major AI conference flooded with peer reviews written fully by AI
Controversy has erupted after 21% of manuscript reviews for an international AI conference were found to be generated by artificial intelligence.

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
