Happy to be at #CMIP26 with my Bristol colleagues. Always amazing to come to the Kokukaisaikan in Kyoto.
👏 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.

This is such a clear visualization of where we are now. From a recent Copernicus report

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.
Paper alert! V pleased to announce my latest paper "The relative role of direct orbital forcing versus CO2 & ice feedbacks on Quaternary climate", in Nature Communications - doi.org/10.1038/s414..., with @natalieslord.bsky.social, @climatesamwell.bsky.social, @thefosterlab.bsky.social + many others!
Analysis of the atmospheric H2 variability over the past millennium suggests that the sensitivity of H2 to climate change should be considered in estimates of the radiative consequences of rising...
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)
