West Sheffield highlighted as a hot spot 🔥🏠

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…

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”

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

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 🤔

@twunderclap @jimmcquaid @CleanAirSheff @SheffieldAir data from 2000-21 are from satellite and ground observations; pre-1998 are from computer climate models, that were previously adjusted with the present-day obs. Hope it makes sense; more info airqualitystripes.info/about/z

@MValMartin @jimmcquaid @CleanAirSheff @SheffieldAir Genuine question. I'd love to know how they measured pm2.5 in 1850, do you know?

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

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

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.

@jimmcquaid Can I have them extracted for Sheffield? 😀

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!

@joraupa @WilliamNB I think I can 😊 I have a few sensors that measure PM25 with GPS. They are very old but still working.

@WilliamNB @MValMartin could you help?

@Farmaenfurecida Vivo en Inglaterra y aquí es así. Súper cómodo! Se firma la autorización online, también dan la opción de no vacunar.

No entiendo el debate sobre vacunar a niños en colegios: ✅ Es más fácil llevar a una enfermera al colegio que a 200 niños al centro de salud. ✅ Evita que pierdan una mañana de clase. ✅ Evita que los padres pierdan una mañana de trabajo.
