West Sheffield highlighted as a hot spot 🔥🏠
Where are the wood burners in England & Wales? Urban areas outside major cities are likely to have the worst #airpollution from wood burning. New mapping highlights #Worthing, #Norwich, #Reading, #Cambridge & #Hastings. Study led by @ucl Story by me. theguardian.com/environment/20…
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”
Hi cycling twitter. I'm Michael, Helen's husband. As some of you may know Helen's last scan showed that the cancer has grown and is impacting kidney function. This means we have reached the end of the road for treatment and are focusing on keeping Helen comfortable.
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 🤔

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

Not the best summer for a research visit to the US… 🤦♀️ reuters.com/world/uk/brita…
PhD apportunity on UK #uplandfires at @ScienceShef @sheffielduni with @UniOfYork and @UKHSA @sheffield_dust @DarpanDas13

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

📢Sound the NEW PAPER klaxon! 📢Transforming US agriculture for carbon removal with enhanced weathering, out now in @Nature nature.com/articles/s4158…
A busy end of the semester for a postdoc in my group, @becky_wagner4! 🎉 She gave a great presentation at the @PPS_UoS internal seminar and a poster at @theAGU. Fantastic work on wetland restoration and earth system modeling! 🌿 #AGU2024

Excited to welcome @RuXu_geo to my research group at @lc3m_cdr and @PPS_UoS! 🎉 Looking forward to working together on oil palm, weathering, earth modeling and more.

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 @jimmcquaid, Kirsty Pringle & team for this great tool and pulling out the data for Sheffield @CleanAirSheff @SheffieldAir

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 @RoySocChem conference: rsc.org/events/detail/…
Congratulations to our Grantham Supervisor @MValMartin who contributed to, and led chapters on, four @DefraUKAir Expert Group reports that were published today! 🥳 You can find the reports here ⬇️ uk-air.defra.gov.uk/research/aqeg/… #AirQuality #AirPollution
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! @CleanAirSheff @SheffieldAir

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!

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
The Clean Air Conference has officially come to an end, but the conversations and action plans continue! 🌱 Big thanks to everyone who made it a success—let’s keep the momentum going for a healthier future! #UKCleanAirConference #CleanAir
Everyone at the Grantham Centre was deeply saddened to hear about the tragic passing of @Graham21, founder of @CleanAirSheff. Graham was an inspiring campaigner & a fantastic person who we were very grateful to have speak at our @FestOfDebate 2024 event. He will be sorely missed.
The world lost a good one. My friend and colleage @Graham21, founder of @CleanAirSheff, 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 💔
