This is very well done.

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!

This is such a clear visualization of where we are now. From a recent Copernicus report climate.copernicus.eu/5-charts-dis...

This year's Global Tipping Points (global-tipping-points.org) conference will be from 12–15th October in Kuala Lumpur, hosted by #SunwayUniversity. Abstract submission and workshop proposal are available via www.sunwayplanetaryhealth.com.my/events/gtp-2...

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.

The UK atmospheric research aircraft (the FAAM) will cease operations in one month's time due to a research 'pivot' by UKRI... www.ukri.org/news/nerc-pi...

👏 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. www.nature.com/articles/s41...

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in PNAS on tropical cyclones from researchers in 🇹🇼 based on "a typhoon series for 1368–1911 reconstructed from Chinese historical documents digitized in the REACHES database".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/...

Read the new blog post by @paultgriffiths.github.io and @soa-mazing.bsky.social on using machine learning in tropospheric ozone science. #egublog #machinelearning #atmosphericscience

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

🚨🧪The ML4O3 Perspective on 'Applications of Machine Learning and Artificial Intelligence in Tropospheric Ozone Research' is published (as a Highlight) today in @egu-as.bsky.social GMD. Great team effort from our many co-authors. doi.org/10.5194/gmd-...

🛰🧪GOSAT-GW (aka Ibuki GW) in the news! Nice story from the Yomiuri Shinbun on the plans for data. Director the Earth System Division at Japan National Institute for Environmental Science, and all-round good guy, Hiroshi Tanimoto presents at COP30. www.yomiuri.co.jp/science/2025...

Congratulations to my former colleague, Jayaprakash Murulitharan, on the award of his PhD. Free Malaysia Today wrote a nice story on his journey. www.freemalaysiatoday.com/category/lei...

My good friend Prof Stuart Maudsley interviewed in @hellobio.bsky.social on the intersection of work and travel (for work). hellobio.com/blog/the-tra...

Glass fragments in firn cores. Fascinating read and also 🤯 "Analysis of glass shards in the firn core from Antarctic Vostok station" by Ro et al., doi.org/10.1038/s432...

NEW EPISODE! @tungohan.bsky.social and Carrianne Leung talk about the energy we bring into the classroom, with students who are coping with realities of fascism, genocide, climate catastrophe, and the uncertainties of AI. Listen on your favourite podcast app: academicaunties.captivate.fm

It's 40 years since Farman, Gardiner and Shanklin's paper analysing springtime ozone depletion over Halley Bay - www.nature.com/articles/d41.... On World Ozone Day 2025, the IO3C reminds us that this is a story of the Earth system's capacity to surprise. www.io3c.org/public-state...

Happy World Ozone day !! youtu.be/Se5shgSACyo?...

By phasing out nearly all ozone-depleting substances, the Montreal Protocol is expected to help prevent up to 1°C of global warming by the end of the century. September 16 is #WorldOzoneDay: ozone.unep.org/ozone-day/fr... @unepozone.bsky.social

"I don't think it was fully realized how much pollution removal would affect the regional climate" says CICERO researcher @bjornsamset.bsky.social Bjørn Samset in a recent story in @newscientist.com www.newscientist.com/article/2494...

I wrote something up for AI people who want to get into bluesky and either couldn't assemble an exciting feed or gave up doomscrolling when their Following feed switched to talking politics 24/7.

Who was the first king of England? 👑 Robinson Fellow, Professor David Woodman, thinks more people should know that Æthelstan created England in 927AD – should his story be on the school curriculum? David makes the case in his groundbreaking new biography 👇 shorturl.at/t07ej

On the 80th anniversary of the bombing of Hiroshima, our Head of Witness and Worship Oliver Robertson traces the history of opposition to nuclear weapons, and how Quakers continue that tradition today. Our faith calls us to work for a peaceful world, free of nuclear weapons 🕊️☮️

On Hiroshima Day, let us draw strength from the tireless campaigning of the last Japanese survivors. Tadayoshi Ogawa: 'We live on something akin to a spaceship...we can fight over borders, over resources, and the spaceship and the life on it will suffer.' www.quaker.org.uk/news-and-eve...

🧪🌳☁️ Short-lived climate forcers affect climate change, air quality, ecosystem health & agriculture productivity. Our new ACP (highlight) paper reviews the research in this area enabled by the CMIP6 AerChemMIP project. Led by @ljwilcox.bsky.social, Bob Allen & me acp.copernicus.org/articles/25/...

Come and join us for our prestigious Annual Lecture and Research Showcase on 8 October where we will be rethinking food and nutrition for the planet. We've got a fantastic panel and keynote lined up and interactive research exhibits to explore. Get your ticket! www.tickettailor.com/events/cabot...

From the back of the room - a great turnout for the UKCA science meeting. Heading towards our community town hall.

Very glad to have Bjorn and Laura’s leadership on this project! And they have written an Explainer - theconversation.com/cleaner-air-...

Spending last autumn at Japan's National Centre for Environmental Sciences showed me the immense effort behind GOSAT-GW, a new Earth observation satellite for greenhouse gases CO2 and CH4. Incredible work by JAXA and NIES. JAXA’s live-stream of its (so far-🤞) launch! www.youtube.com/watch?v=MZop...

From the back of the room - this was a fantastic day. Thanks. Particularly enjoyed the overview of lab education from @mkseery.bsky.social

Alas IWGGMS is over but it’s been a great workshop. Can’t wait for the next trip to Shikoku!

Nice trip from Hiroshima to Takamatsu for IWGGMS. TIL that the cat that rides with Kumanaku the JR mascot is called Tabinyan.

Just published in @uk.theconversation.com w/ @ljwilcox.bsky.social! Our article explains why Delhi can't break free from its Air Pollution Crisis and explores how meteorology is just as important as emissions in the fight for cleaner air! Read more: theconversation.com/delhi-how-we...

Please consider submitting an abstract to the session on 'Understanding reactive gases, aerosols, and land use for air quality and climate change' convened by Fiona O'Connor, @dwatsonparris.bsky.social, Stephanie Fiedler, @flossie-brown.bsky.social and me! Deadline August 13th.
