West Sheffield highlighted as a hot spot 🔥🏠

[Gary Fuller @DrGaryFuller]

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.

Not the best summer for a research visit to the US… 🤦‍♀️ https://t.co/ditm1Birml

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 https://t.co/2m0MywBgpf

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”

[CyclingInASkirt @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.

[Dr Maria Val Martin @MValMartin]

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 🤔

[Dr David Yates @DavidYatesPhD]

The Star have picked up this story now.

University of Sheffield VC claimed £17k in business class flights amid £50m shortfall https://t.co/pvsLnDB2ds

@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 https://t.co/qwwf66dSrz

[Dr Maria Val Martin @MValMartin]

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

[Dr Maria Val Martin @MValMartin]

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

[Dr David Yates @DavidYatesPhD]

One university.

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.

[Dr Maria Val Martin @MValMartin]

@jimmcquaid Can I have them extracted for Sheffield? 😀

[Gary Fuller @DrGaryFuller]

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

[Dr Maria Val Martin @MValMartin]

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

[Dr Maria Val Martin @MValMartin]

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!

[Dr Maria Val Martin @MValMartin]

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