In a new study, published today in Nature Climate Change, we explore how carbon dioxide removal (CDR) – approaches that take CO2 out of the atmosphere – may affect #biodiversity. 🦎🐌 doi.org/10.1038/s415...
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!
🎉 My first publication is out in Geoscientific Model Development!

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.
Reduced Complexity Model Intercomparison Project Phase 3 preprint: egusphere.copernicus.org/preprints/20...
In parallel to experiments run by complex climate models, we evaluate the simple climate models that are used as translations of knowledge from physical science to scenario projections
Group of five people standing outdoors holding copies of the Austrian Climate Report, smiling at the camera. A cityscape with glass buildings appears in the background. Text reads: "How Wikimedia Austria made climate science accessible by bringing it to Wikipedia."
The 800-page Second Austrian Climate Report (AAR2) is now more accessible thanks to Wikimedia Austria.
Open licensing and a Wikimedian in Residence helped bring key findings to Wikipedia, Commons, and Wikidata, connecting climate science to everyday life.

Minor update in morning estimate
I'm assuming Ipsos just shares the data directly with NOS, not anything else. The NOS website reads "© NOS. Bron: IPSOS, in opdracht van NOS en RTL"
Ah fair question - no I just based it on the news reporting.
Do you have a link?
No changes in the 21:30 exitpoll update.
Dutch general elections happened today.
First exit poll is here.
Dutch elections not easy to cover / explain: so many parties (~15)!
Since last year, I'm trying to track the votes by party colour - here's how I grouped it.

In addition to @openclimatedata.net on AR5; section 2.1.2 tried to summarise this for all ARs: gmd.copernicus.org/articles/15/...
After writing it, I also wanted to do this. So if you embark on it I'm keen to help. I did already collect even older emissions data (RCP, AR4, SRES, even IS92!)
📣 Last days to apply as a Chapter Scientist to support author teams for IPCC’s Seventh Assessment Report.
The deadline for applications is 18 October 2025.
More details: lnkd.in/dGvmmWeC
🚨 Important paper in Nature: "Systematic attribution of heatwaves to the emissions of carbon majors".
www.nature.com/articles/s41...
The @ipcc.bsky.social has announced the authors for its Seventh Assessment Report (#AR7). With 3 Coordinating Lead Authors & 10 Lead Authors, IIASA will play a key part in delivering the best available knowledge to guide effective and equitable climate action.
🔗 iiasa.ac.at/news/aug-202...
So, feel free to connect/reach out with anything you feel may be helpful research and suggestions!
Attached a screenshot with the topics we will cover in our chapter.
All chapter outlines: www.ipcc.ch/site/assets/...
In light of the International Court of Justice’s reaffirmation of the importance of IPCC reports, I believe its very important to do our best to improve on past reports, as a scientific community, providing solid scientific evidence for what's very urgent: good, well-informed, climate action.
Honoured to serve as a Lead Author for the IPCC’s Seventh Assessment Report!
Chapter 3, WG III. I expect to focus on global mitigation pathways, decent living standards for all, and post-growth approaches.
Team looks great! First big meeting in December.

This is amongst the most impactful two minutes of broadcasting I’ve ever seen.

- also here showing 'human-induced' forcing (only anthropogenic), whereas the paper generally presents data including also natural forcing (regular solar cycles). These solar cycle peaks can affect the total forcing or temp peaks a small bit too
A few subtle differences:
- Fig 3 is temperature, not Effective Radiative Forcing
- the plot Ken is showing picks a few 'illustrative pathways', to highlight higher (two left) and very low (two right) climate outcomes. The paper always looks at larger _groups_ of scenarios
Thanks Ken :).
I thought this was a time to keep the y-axis constant across panels to highlight exactly that and accept that half of the facets are just whitespace -- show those contributors to warming don't matter nearly as much as CO2.
🚨Submission deadline ahead🚨
Join us for the world's first global conference at @iiasa.ac.at from Sep 30 to Oct 02.
(Extended) abstract deadline is around the corner (July 4). Don't miss it!

New study out, in which we detect a causal link in reanalysis+observational data from an AMOC SST index to the Southern Amazon rainforest: dry season precipitation increases when the AMOC weakens.

Yes, these scenarios also include (lots of) decarbonization
That's definitely crucial. The scenarios themselves (created with integrated assessment models) in this paper suggest start from the current infrastructures and project pathways of structural change away from that.
