The world lost a good one. My friend and colleage GT 🍃💚🍃, founder of Clean Air Sheffield, passed away. He cared deeply for Sheffield and worked tirelessly for cleaner air. His legacy will live on in the work he did for all of us. Sending love to everyone who knew him 💔

Everyone at the Grantham Centre was deeply saddened to hear about the tragic passing of GT 🍃💚🍃, founder of Clean Air Sheffield. Graham was an inspiring campaigner & a fantastic person who we were very grateful to have speak at our Festival of Debate 2025 2024 event. He will be sorely missed.

Fantastic event! It was busy but full of interesting conversations, all focused on tackling air pollution and making our air healthier and cleaner! 🌱 Many thanks to the organizers #UKCleanAirConference

Last week’s #PCF2024 symposium in Japan on plant-climate feedback and BVOCs was fantastic! 🌱🌍 Great talks, discussions, and a welcoming group of experts. Already looking forward to the next one in 2026!

Sheffield’s air quality is taking a serious hit tonight with Bonfire Night. PM2.5 is rising to toxic levels—my @sensorcommunity sensor is recording 40 µg/m³, and you can even smell it in the air. Consider limiting time outdoors if you can! Clean Air Sheffield Sheffield:Air

Congratulations to our Grantham Supervisor Dr Maria Val Martin who contributed to, and led chapters on, four Defra Air Quality Expert Group reports that were published today! 🥳 You can find the reports here ⬇️ uk-air.defra.gov.uk/research/aqeg/… #AirQuality #AirPollution

Wow- four AQEG reports published last week: - AI in air quality - Horizon-scanning: Seven potential risks of relevance to the UK - New Opportunities for Particulate Measurements - Air pollution from H2 Find out more at December's Royal Society of Chemistry conference: rsc.org/events/detail/…

Excited to share the Air Quality Stripes for Sheffield! 🌍 They show past PM25 pollution, progress since the Clean Air Act & work still to do. Big thanks to Jim McQuaid 🇺🇦 🇪🇺, Kirsty Pringle & team for this great tool and pulling out the data for Sheffield Clean Air Sheffield Sheffield:Air

Excited to welcome Ru Xu to my research group at Leverhulme Centre for Climate Change Mitigation and Plants, Photosynthesis and Soil! 🎉 Looking forward to working together on oil palm, weathering, earth modeling and more.

Meanwhile, academics and staff are being asked to apply for voluntary severance… Priorities? 🤔

Beyond voluntary severance, departments are turning off lights for Christmas, cutting international field courses, warming freezers from -80°C to -70°C, etc to reduce the uni’s carbon footprint… while the VC flies business class 🤔

A busy end of the semester for a postdoc in my group, @becky_wagner4! 🎉 She gave a great presentation at the Plants, Photosynthesis and Soil internal seminar and a poster at AGU (American Geophysical Union). Fantastic work on wetland restoration and earth system modeling! 🌿 #AGU2024

I’m so sorry to hear this, Michael. Thank you for letting us know. Sending a big hug to you all. I didn’t know Helen personally, but I used to cycle alongside her on my way home from work. I admired her confidence and style cycling in a skirt—I knew she was “cyclinginaskirt”

On #InternationalWomensDay, I celebrate my grandmother—my inspiration. A mathematician in Spain, she raised 6 children, lived through a civil war & dictatorship, and became the first woman to lead a School of Education at a Spanish university 💜 #IWD2025

It's that time of year again... widespread elevated #particulate #airpollution across #Yorkshire and eastern England right now. Here is #Leeds Centre (data from Defra Air Quality).
