✨ New preprint out! ✨ Really happy to share that our manuscript “Reduced Complexity Model Intercomparison Project Phase 3: Experimental protocol for coordinated constraining and evaluation of Reduced-Complexity Models” is now available as a preprint on EGUsphere 🔗 Preprint: doi.org/10.5194/egus...

As part of our 10th anniversary celebrations, we recognised four outstanding members of the Priestley community Congratulations to Alex Romero Prieto, Elliott Johnson, Prof Alex Beresford & Dr Ruth Bookbinder for their impactful climate research and collaboration. climate.leeds.ac.uk/news/priestl...

Just arriving in Vienna for #EGU! If you’d like to chat about RCMIP, come by my poster on Thursday at 14:00 (session NP1.2 in Hall X4). Or just stop by to say hi!

Yesterday, Piers Forster presented Defining National Fossil Fuel Phase Out Roadmaps: A Colombian Case Study at a side event at TAFF in Santa Marta. Key to the roadmap was the work of Priestley researchers Elliott Johnson and Alejandro Romero Prieto. Here's Alejandro's thoughts on the conference.

It's day 5 of the Transitioning Away from Fossil Fuels Conference in Colombia. Today at 10–11, Colombia Time, Priestley will host a side event on the Fossil Fuel Phase Out Roadmap followed by a discussion. www.eventbrite.co.uk/e/a-roadmap-...

At the Transitioning Away from Fossil Fuels Conference, Prof Piers Forster launched a draft national roadmap for fossil fuel phase-out: a Colombia-based, collaborative and science-led case study, demonstrating how roadmaps can support a just transition www.youtube.com/watch?v=Txuu...

We're excited to announce that Priestley Centre Director, Piers Forster, is speaking at the Transitioning Away from Fossil Fuels Conference in Colombia. 18:00 Colombia time today, he’ll present the draft national roadmap for fossil fuel phase-out in Colombia. #TAFF #ClimateScience #EnergyTransition

Had the opportunity to talk a bit about my PhD journey to PLOS Climate! Check the blog entry below 😁

Friendly reminder: only a few days remain to submit your model output for the next RCMIP round. If you’d like to participate but the deadline is… rapidly approaching, do get in touch. We can likely be flexible and accommodate slightly later submissions.

Wild figures in two decades of EIA retrospective data. Solar getting it wrong gets all the airplay. But the consistent underestimation of natural gas exports and the speed of coal's collapse are just as striking, even at 3-5 year horizons.

National carbon budgets are smaller than commonly assumed because scientists and countries count CO₂ differently. Our new study in Nature Communications corrects for this and finds that the 1.5 °C budget shrinks by ~50%, the 2 °C budget by ~20%. Paper + data: www.nature.com/articles/s41... Thread 👇

Public discussion on the RCMIP3 protocol paper has now been opened! Do send us your thoughts if you have any ideas on how we could make the intercomparison better!

New paper in ERL in which we study the effect of a long-known issue in climate emulators: that we typically calibrate them on only 150 years of 4xCO2 ESM runs. This a problem as we know the climate isn't in equilibrium after this time, but running ESMs is 1/N iopscience.iop.org/article/10.1...

Excited to convene the upcoming EGU webinar on "Mental Health in Academia: Obstacles, Advocacy and Inclusion" on 9 February at 16:00 CET. Open to all. 👉 Register here: www.egu.eu/webinars/694... @egu.eu @egubg.bsky.social @anabastos.bsky.social @elsa-abs.bsky.social

🌍 Working on climate model emulation or impact projections? ➡️ Abstracts are still open for our EGU 2026 session “Advances in climate change emulation for impact projections” (#CL3.2.7) SCMs, ML, emulator evaluations, impacts & more welcome. 🔗 Session info + link: www.egu26.eu/session/56612 #EGU26

Newly published: an overview of FRIDAv2.1, a new IAM to model the coupled human-Earth system (including climate impacts!) gmd.copernicus.org/articles/18/...

OUT NOW: Global Tipping Points Report 2025 global-tipping-points.org Our chapter on the "Implications of overshooting 1.5°C for Earth system tipping points" is based on an associated paper: doi.org/10.31223/X52... Minimizing climate overshoot is essential to prevent climate tipping points.

Only a few days left to send us your feedback about our plans to run the upcoming RCMIP phase!

Our paper is out today in @nature.com where we assess a Prudent Planetary Limit for Geologic Carbon Storage: www.nature.com/articles/s41...

Excited for the conference tomorrow in my home city. If you are also attending and want to meet drop me a message, happy to chat between sessions!

Currently travelling to Manchester for the Royal meteorological society early careers and student conference, where I will be chairing the session on extreme weather events as part of the organising committee. Do say hi if you are around!

Reminder: call for abstracts for the CMIP Community Workshops. Latest developments in models & approaches, reflections on CMIP6, explorations on CMIP7, etc. In particular for those related to climate emulators, I encourage you to check the session 29. All info here: wcrp-cmip.org/event/cmip26/

I want to connect with and highlight more trans voices working with plants, wildlife, and the natural environment so I've created a starter pack! If this sounds like you, introduce yourself by quote-posting this skeet and I'll add you to the list 🏳️‍⚧️

reminder, bsky has a clever way to display pronouns that's built in! but you only see them if you yourself opt in, so please feel free to here by subscribing and then choosing which applies!! @pronouns.diy

New paper on the risks of forest ecosystem impacts under emissions pathways designed to meet the Paris Agreement temperature goals is out today in Nature Climate Change! 🌳 Read it here: www.nature.com/articles/s41558-025-02327-9

New study on linking wealth-based emissions to climate impacts: We find that 2/3 of global warming is attributable to the wealthiest 10% and so are climate extremes. Article: www.nature.com/articles/s41... @iiasa.ac.at, @usyseth.bsky.social 1/
