NEW ANALYSIS: China's CO2 has now been 'flat or falling' for 21 months

* Down in 2025
* Still below Mar 2024
* Clean energy wave a key factor

If this is China's peak (TBC) it's the climate story of the century so far…

Very aware that none of this happens without a brilliant research group and collaborators around me.

Y gwyddonydd Ifan Stephens a'i lwybr 'aflinol' i lwyddo Llwyddiant Ifan Stephens o Gaerdydd ym maes catalyddu a'i falchder i ennill gwobr wedi ei enwi ar Γ΄l ei fentor, Syr John Meurig Thomas.

Braf iawn oedd cael sgwrs gyda Angharad Rhys o BBC Cymru Fyw am fy nhaith aflinol mewn gwyddoniaeth.

Yn ogystal Γ’ electrocemeg a chatalyddu, buom yn trafod Syr John Meurig Thomas, a pham mae cynhwysiant yn hollbwysig os ydym am lwyddo i ddatrys problemau mawr y byd drwy wyddoniaeth.

Great to chat with BBC Cymru about my non-linear path in science.

Alongside electrocatalysis, we touched on everything from Sir John Meurig Thomas to why EDI really matters in materials science.

The news has been more than a bit grim of late, so hooray for @carbonbrief.org providing some genuine and really meaningful **good** news: the UK's carbon emissions in 2024 were the lowest since 1872, because demand for fossil fuels just keeps decreasing.

I finished off yesterday at the Queens Arms at the pub catching up with Soren Scott who has now been Assistant Professor at @ucph.bsky.social for 15 months! Although we miss him sorely at @interfacial-ec.bsky.social, I am so pleased to see he is going from strength to strength in Copenhagen!

GPs halting transgender patients’ hormone treatment or refusing prescriptions Investigation: GPs cite lack of expertise or funding as key factors in withdrawals of trans patients’ prescriptions. Billie Gay Jackson and Holly Bancroft report

The UK continues to quietly force trans adults to detransition. It was never about trans youth. Doctors in the UK are withdrawing hormones without warning and cutting tags people off even after decades of being on HRT.
