New paper with @glenpeters.bsky.social in Nature Communications today. We show how models and studies with a lot of scenarios in the IPCC scenarios database have a large impact on key findings, including emissions reductions, net-zero GHG year, and coal, gas, and oil consistent with 1.5°C.

India more than halved a tax rate on domestic sales of renewable-energy equipment, as part of a raft of measures to shore up local consumption and shield the economy from punitive US tariffs

It’s not just fossil fuels at risk of becoming stranded — without good policies, even decentralized renewables could be left behind. We have looked at this issue in this paper.

#LowCarbon #MiniGrid assets face risk of asset stranding, with the expansion of or improvement in reliability of national grids. Good #Policy to ensure these assets can interconnect can reduce this risk, + improve reliability, #emissions and costs! Read the paper here: www.nature.com/articles/s41...

The study uses #energy system #modelling to explore different scenarios of national grid/mini-grid reliability in #India, and how under different #scenarios, national grid connected mini-grids can offer a promising solution providing clean, affordable and reliable power. ‪@powerforall.bsky.social

Sharing our new paper in #NatureCommunications on solar-based mini-grids interconnecting with national grids can boost reliability, cut costs + emissions, and reduce the risk of asset stranding, co-led by @benwinchester.bsky.social & with @shivmit.bsky.social, + others! @natureportfolio.nature.com

The DIAMOND project has made an important milestone: the first draft release of six open integrated assessment models (IAMs) that are emblematic in both scientific and policy processes. Now is the chance to contribute and provide feedback! preview.mailerlite.com/y7x9l4x1r1

I never thought I would be spending my time explaining the scientific method to one of the most well funded research institutions in the history of humanity, but here we are. But it was so uplifting to see so many brilliant scientists provide context to every point in this thing. You guys rock.

"President Donald Trump’s crusade against wind energy is intensifying — and it could come with some serious costs. As much as $317 billion in lost investment, to be exact, per new analysis from research firm Cleanview." www.canarymedia.com/articles/win... via @danmccarthy.bsky.social 🔌💡

India has just announced that they have reached their NDC target of 50% non-fossil electricity generation capacity share. Good to celebrate progress, but generation share is still about 25%, and has been fairly stable for several years. 1/3 robbieandrew.github.io/india/

DIAMOND is holding a webinar tomorrow, June 17, for researchers engaged in climate scenario development + assessment, especially those working with integrated assessment models ( #IAMs ), energy-economy models, & broader scenario exercises. climate-diamond.eu/diamond-webi... #climatediamond

Our paper presents a new, open-source, quantitative, multidimensional framework designed to explore and evaluate these scenarios systematically. It can be used to assess scenarios globally or regionally.

Large collections of #climate action #scenarios are crucial for guiding #policy, but can be challenging to extract insights from. It's helpful to understand the relative feasibility and also desirability for society of scenarios across a range of relevant dimensions 🧭 (2/8)

🚨Excited to share my new paper published in ERL: "An exploration and evaluation framework for climate change mitigation scenarios with varying feasibility and desirability", co-authored with @shivmit.bsky.social @robinlamboll.bsky.social @joerirogelj.bsky.social tinyurl.com/yh3rspns (1/8)

“Acceleration” has become increasingly prevalent in discourse on climate mitigation. What does it mean? It often means "step up" climate action in the short term, which is overly simple. Acceleration must end, which requires thinking about policies over time. journals.plos.org/climate/arti... 1/

The EU has released its latest GHG emission inventory, with data up to 2023. The good news, GHG emissions continue a downward trend, currently 37% below 1990 levels. The bad news, a significant downward revision of land-use removals (LULUCF). 1/

We're excited about finally getting this one out in discussion. METEOR is a lightning fast time-evolving spatial pattern response model which can emulate any CMIP model, representing separate slow and fast climate responses to different climate forcers. egusphere.copernicus.org/preprints/20...

This is not a surprise. We know what causes CO₂ to increase in the atmosphere and we know how to stop climate change. We just don’t want to.

Deadline in two days! Join us in Paris in May to discuss how to improve the science on explaining GHG emission reductions!

In a new paper, we look at how we can allocate the global warming space instead of carbon budgets and translate it to warming-equivalent emissions budgets. Noteworthy, many developed and advanced developing countries have already by far exhausted their fair warming budget. (1/2)

Draft chapter outline for IPCC AR7 WGI is now public - *subject to approval* at the plenary, end of Feb What's new? Compared to AR6: -More concise -greater range of modeling approaches -chapters span Earth System domains -considers diverse physical scenarios /thread/ apps.ipcc.ch/eventmanager...

The outlines from the IPCC AR7 Scoping Meeting are now public. For WGIII, the draft outline (WG-III: 15th/Doc. 2) & background (WG-III: 15th/INF. 1), with Ch2 & Ch3 below (my areas). Comments? These are draft documents, potentially modified, then agreed by the IPCC: www.ipcc.ch/meeting-doc/...

Researchers paid nearly $9 billion to publishers between 2019 and 2023 so you could read our work. Why? Why??

Considerations of fairness in mitigation efforts can get complicated (see earlier post), especially when we look beyond CO₂. In a new paper led by Mingyu Li, we propose an approach to address this, allocating a remaining 'global warming budget' to countries in line with the Paris Agreement’s goals.

"Over the last decade, emissions have grown, & climate targets have become more ambitious, yet the investments & costs needed to limit global warming to below 1.5-2°C did not increase..." Hmmm, what has happened there? Read @ciceroclimate.bsky.social www.cicero.oslo.no/en/articles/...

How have emissions scenarios changed in the last 10 years? Has mitigation actually become easier, as costs of key technologies have declined? I write more about it on LinkedIn www.linkedin.com/pulse/has-cl... Or go check out the main article: rdcu.be/d7cUB
