I know!!! I was outvoted

If you want to get your simple climate model picked up by IPCC AR7, see below 👇

We have 11 on our radar from the previous round of RCMIP (egusphere.copernicus.org/preprints/20...), plus a few others we found since.

Anybody we don't know about please ping me or Alex

send me a PM :)

Now that it's public, I'm very honoured to be selected as Coordinating Lead Author of Chapter 5, Working Group I for the IPCC Seventh Assessment Report 📚🌍

Our chapter is one hell of a team!

also very willing to help if you get stuck. Sorry the new interface is clunky - I went speed over intuition.

A deep dive into the world of simple climate models: preprint out from @arp-climate.bsky.social.

we know this isn't exhaustive - we focus on the models that participated in RCMIP phases 1 and 2. There will be a phase 3, coming soon.

We (@tim-andrews.bsky.social, Ryan Kramer and I) are leading a session around understanding radiative forcing in models at the CMIP Community Workshop in Kyoto, Japan, next March. Abstract submissions open until 13 August:

Please get in touch with Team @carbonbrief.org if you're in Bonn this week – @mollylempriere.carbonbrief.org + @joshgabbatiss.bsky.social have just arrived

It's that time of year again!

I'll be in Bonn covering the #SB62 UN climate talks until the end of the week with @mollylempriere.carbonbrief.org

Keen to hear the hot takes on climate finance, loss and damage and anything else you think is interesting

In this Carbon Brief post we talk about the implications of not including future volcanic eruptions in climate scenarios, as described in our recent paper: www.nature.com/articles/s43...

I'll be giving a short talk on 1.5°C at a mini-symposium at VUB on Friday 6 June as part of an event celebrating the award of an honorary doctorate to @joerirogelj.bsky.social, see below for details and registration!

Some sessions that ought to be fun & interesting:

🔷 ID4 RFMIP: Exploring radiative Forcing in models and observations to understand climate change

🔷 ID5 CERESMIP: Confronting models with observed changes in the Earth’s energy imbalance

🔷 ID15 CFMIP: Clouds, circulation and climate sensitivity

The CMIP Community Workshop 2026 will be held in Kyoto, Japan from 9-13th March 2026. The call for abstracts for CMIP26 is now open! Find out more at wcrp-cmip.org/cmip26-call-...

To all of my friends in Oslo, I am presenting at the Joint Oslo Seminar tomorrow at UiO! It will be the full-fat version of my EGU talk:

Updated IPCC emissions scenarios no longer limit warming to 1.5°C

It should be, but I don't know if this will happen again this year. So get in early :)

Here's @arp-climate.bsky.social presenting on the upcoming process-based carbon cycle in FaIR at #EGU25!

It's subtle. I'll show you in Oslo
