WOW! As of this morning only about 350 letters had been sent out urging our Delegates to hold data centers accountable and lower our energy costs. BUT after we blasted this call to action, we hit our goal of sending over 1,000 letters to our Delegates. Keep going! actionnetwork.org/letters/shif...

Ofgem, the UK energy regulator, has disclosed that 140 data centres want grid connections, requiring **50GW** of power capacity at peak Britain’s peak demand on a recently was 45GW Can this amount of energy be provided cleanly? Even if it can, is it worth it? www.thetimes.com/uk/environme...

Big Oil "purchased solar and EV patents to ensure others couldn’t use them, solicited control of renewable markets and then abandoned them, and funded powerful institutions to promote false solutions, all while using trade groups to downplay the harms of fossil fuels, according to the complaint." 😠

this is a top @stuti.bsky.social piece and I also find the headline so interesting - 'proof the green transition isn't dead'. I cannot imagine how anyone could even really formulate the idea that it *is* dead? I guess because they hear about it less; therefore assume it just died??

Fascinating figure from the EIA. The part at the bottom highlights the repeated patterns of policies reaching end of life, and being renewed again. Over and over again. A consequence of this was that EIA's projections, based on current policy, kept saying that US wind installations would stall.

While our best estimate is that US fossil-fuel CO₂ emissions went up about 2% in 2025, the EIA is currently forecasting a drop of 2.2% in 2026. robbieandrew.github.io/USA/

2025 was the third-hottest year on record, coming in behind 2023 and 2024 and making it clear that climate change has arrived.

Interesting to note that the end of 2025 did not see the usual surge in sales. There have been policy changes and pressure from the government on the industry to rein in the steep discounting we've seen previously. Dec 2025 sales were 14% lower than Dec 2024. www.cpcaauto.com/newslist.php...

Not just any researcher. Rob Lempert!

Inefficient Jet Engines Repurposed for AI Data Centres. Rising electricity demand from AI is pushing tech firms to use repurposed jet engines for data centres. Only about 40% efficient, they burn far more fuel than modern power plants as grids struggle to keep up. www.telegraph.co.uk/business/202...

The carbon market is not the way to do CO₂ removal (CDR). If we're serious about this, it has to be a government-led effort.

When any government receives negative information about their inflated base year emissions due to improved methodologies, they should correct their course and increase mitigation efforts instead of maintaining the reduction target in the revised NDC. Here is one example from Nigeria NDC.

"Here is the graph, which is so wild, the climate scientist had to call a colleague & check it" It is true actually! In the Global Carbon Budget we do not usually show the LUC like this, because of interannual variability & uncertainty. But it is what the data says! politiken.dk/klima/art106...

Global Greenhouse Gas (GHG) emissions rise again in 2024, up 2.3%. This is our collective progress, 10 years after the Paris Agreement. www.unep.org/resources/em... 1/

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.

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

Read the full paper here! iopscience.iop.org/article/10.1... #ClimateChange #ScenarioAnalysis #IntegratedAssessmentModels #Feasibility

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...
