🚨 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...

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. All authors: apps.ipcc.ch/report/autho...

This is amongst the most impactful two minutes of broadcasting I’ve ever seen. By Emma Murphy, International Editor, ITV News. #Gaza

🚨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! overshootconference.org/abstract-sub...

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. doi.org/10.1088/1748...

🌍 New publication – and the final paper of my PhD! Can we end poverty, provide decent living standards (and beyond) for all, and meet climate targets? 📄 Paper (open access): “Closing decent living gaps in energy and emissions scenarios: introducing DESIRE”: iopscience.iop.org/article/10.1...

New IIASA-led research shows that achieving sustainable development and climate targets at the same time is not only possible but necessary. “Eradicating poverty and protecting the planet are not conflicting goals,” says lead author @kikstra.bsky.social. 🔎 iiasa.ac.at/news/may-202...

“We’re not just talking about lifting people out of extreme poverty; we’re looking at futures with high development ambition, ensuring decent living standards as a minimum for everyone worldwide.” @kikstra.bsky.social, @iiasa.ac.at

Read about our new work on 'net zero carbon debt' @carbonbrief.org 👇

What's the fairest way to deal with the (inevitable) overshoot of 1.5°C? New paper led by @setupelz.bsky.social explores the concept of "net zero carbon debt" Here's the VUB press release: press.vub.ac.be/who-is-respo...

With global warming closing in on 1.5C, one aspect is clear: some countries' emissions have exceeded their fair share. To deal with this, we present the concept of carbon debt in a new paper in @pnas.org. Lead author @setupelz.bsky.social explains in a long thread 👇🧵

With 1.5°C being dangerously close, moving the goalpost might seem tempting. In this extremely relevant contribution @setupelz.bsky.social and co-workers @iiasa.ac.at suggest an alternative: Keep the target - and keep the books. Carbon debt for climate integrity 👇👇👇

📢 New paper w/ G. Ganti @robinlamboll.bsky.social L. Grant @cjsmith.be @shonali-p.bsky.social @joerirogelj.bsky.social K. Riahi @wimthiery.bsky.social @gidden.bsky.social We examine a forward-looking measure to guide collective efforts in the era of climate overshoot: net-zero carbon debt. 🧵

OK, seriously, Dr. Kate Calvin is one of the best, most well rounded climate scientists alive. She is the current co-chair of IPCC WGIII AR7, and a fabulous leader. Eliminating her current position as Chief Scientist at NASA is not just a shot in the foot, but an amputation. @ipcc.bsky.social

Not a new nature fund just yet, but developing countries get something much bigger, 3 decades in the making: a permanent mechanism for biodiversity finance. Esp significant in today's geopolitical climate that has cast a cloud over cooperation and hopes for more funding for nature and climate.

I have been receiving the sad news about massive NOAA firing. I cannot explain how important NOAA is for science globally. The data and model outputs generated by NOAA globally allow researchers from countries that don’t have the funding or capability to develop those to do their own science. 🌊🧵

Do you want to work on improving some of the most widely used global climate datasets? We are offering a 34-month research / climate data science post to further develop CRU TS and CRUTEM @climateuea.bsky.social @ncas-uk.bsky.social vacancies.uea.ac.uk/vacancies/14...

Last Tuesday, I was set to give a talk on 'climate change in the Northeast' at a retirement home but had to cancel due to hourly job threats. After nearly two weeks of overwhelming uncertainty, today it happened. I was fired from my dream of working at NOAA. I'm so sorry to everyone also affected.

Scenarios from Integrated Assessment & energy systems models are an important part of the policy discourse for getting to net-zero. IIASA, IAMC and the Earth Fund are starting a new initiative to make these scenarios more accessible and actionable! #ScenarioCompass scenariocompass.org/news

Feels weird reposting this with everything that's going on, but... We are compiling an emissions & energy scenario ensemble that will hopefully be useful to IPCC AR7. Submission deadline March 1. A little step towards #OpenScience and #FreeTheModels... #ScenarioCompass

Have you ever wondered if the global leadership on climate would be less depressing if we had more Luisas and fewer Elons? With gender equality backsliding everywhere, it’s super important to stress its role in addressing the climate crisis. A 🧵 on our new paper on gender equality & scenarios:

Comparing our ‘fair warming’ budgets to deepest available domestic reduction (DADR) pathways shows that high domestic ambition is unlikely to be sufficient for many. This underscores a major challenge: the need to address expected breaches through international cooperation (more on this soon...).

Fairness has always been central to international climate talks, and its interpretation has been diverse, to say the least... Our new paper identifies key ‘entry points’ where crucial, often hidden, decisions are made that underlie fairness assertions in practice. iopscience.iop.org/article/10.1...

Climate action is falling terribly short Time to bury the 1.5C goal? Absolutely not - why the 1.5 goal must prevail (even when global warming exceeds 1.5C) My opinion for Project Syndicate 👇 www.project-syndicate.org/commentary/a...

Accountability. Key to achieving climate justice is to hold responsible high emitters. We need to increase accountability. Taking 1.5C off the table decreases accountability; it risks reducing the climate debt of rich countries, beclouding what the accountability target should be. Let's not? Read:

For the Imperial College Sustainability Week, I wrote a blog on a just transition with decent living standards. The post reflects on: what is justice, what can we know about a just transition, and models supporting our thinking (not replace it).

The Shared Socioeconomic Pathways (SSPs) are a key input to climate change mitigation & adaptation research - but what about urbanization, structural change & governance? Join the launch webinar of the SSP-Extensions Explorer! 🗓️29 Feb 2024 ⏰15pm CET iiasa.zoom.us/webinar/regi...

This is one of my favourite reports from the past few years, and it has gone a bit under the radar which we should try to correct: it lays out the physical damage and destruction caused by maintaining reliance on fossil fuels (enabled by increasing their supply)

‪At a webinar last week, Samir KC (IIASA), Rob Dellink (OECD) and Jesus Crespo Cuaresma (Vienna University of Economics and Business) presented the updated population & GDP projections.‬ ‪You can find the recordings 🎥 & presentations 📝 at www.iamconsortium.org/event/joint-...

Last week, the Integrated-Assessment Modeling Consortium (IAMC) & ICONICS released an update of basic drivers of the the "Shared Socioeconomic Pathways" (#SSPs). They are an integral part for scenario research on climate change mitigation & adaptation. Visit data.ece.iiasa.ac.at/ssp for more info!
