For a century, we’ve essentially been running an Enhanced Weathering field trial. In our Nature paper out yesterday, we show that agricultural liming in the Mississippi River Basin acted as a net CO₂ sink—while offering a rare century-scale analogue for EW. www.nature.com/articles/s41...

Enhanced weathering publications are growing exponentially. Based on our just-updated literature list (doi.org/10.5281/zeno...), for peer-reviewed terrestrial EW papers, the estimated doubling time is ~2.8 years (R² = 0.92). Outside formal peer review, growth is even faster: ~1.3 years (R² = 0.88).

What if carbon removal could help clean PFAS-contaminated soils—and help pay for it? Our new paper explores a potential win-win-win: enhanced weathering can boost plant PFAS uptake, while pyrolysis destroys PFAS and stores carbon as biochar. paper: doi.org/10.1073/pnas...

Want to learn more about enhanced weathering? Based on a novel data synthesis effort, the preprint compiles evidence on geochemistry, MRV, CDR fluxes & potentials, costs, LCA, side effects, governance, policy and deployment readiness. Two key figures below. Link: doi.org/10.70212/cdr...

Is agricultural liming a CO₂ sink or source? In our preprint, we argue that the key is the counterfactual: CO₂ emissions are driven mainly by acidity inputs, not lime itself. In the Mississippi Basin, liming reduced CO₂ emissions and increased alkalinity export. Preprint: doi.org/10.21203/rs....

What works in the ocean may not work in soils. Our new paper shows that total alkalinity titrations—robust in seawater—can be misleading in soils due to organic alkalinity. We argue that charge-balance & cation-based accounting may be more robust for terrestrial CDR. doi.org/10.5194/bg-2...

Reviews and syntheses: Carbon vs. cation based MRV of Enhanced Rock Weathering and the issue of soil organic carbon

Abstract. We discuss the “monitoring, reporting and verification” (MRV) strategy of Enhanced Weathering (EW) based on carbon accounting and argue that in open systems such as arable land, this approac...

More is better 🌍—at least for monitoring enhanced weathering. Our new preprint shows that larger catchments & aggregated soil data cut noise, lower costs, and prevent over-crediting. Crediting must move beyond single fields. See link below.

🔖🪨🚜🌧️🌊📉 Thanks to @phys.org.web.brid.gy for this article on @climatejesper.bsky.social's talk yesterday at @goldschmidt-confer.bsky.social on the potential for novel frameworks for the application of agricultural lime to drive durable CDR via enhanced weathering at low cost phys.org/news/2025-07...

Agricultural liming in the US is a large CO₂ sink, say researchers

Adding lime to agricultural soils can remove CO2 from the atmosphere, rather than cause CO2 emissions, claims new research.

Our new paper shows that soil cation exchange can delay CO₂ removal from enhanced weathering by years to decades. Lag varies by soil, climate, and land use—longest in high-CEC regions like the Corn Belt. Big implications for MRV, credit timing, and deployment strategy. Timing matters! 🪨🌾 Link below.

Check out our new pre-print on how to use soil mass balance (“TiCAT”) to quantify rock dissolution in enhanced weathering trials. Includes key do’s & don’ts, a deep dive into signal-to-noise (constrained in data from from 5 sites), and open-source code to try it yourself. Feedback welcome! #EW #CDR

Excited for #ERW25! If you’re around and want to chat — soil mass balance, aggregated monitoring, or ERW topics — reach out, especially if we haven’t met! Enjoyed Isometric’s workshop yesterday and getting to discuss how to scale enhanced rock weathering responsibly and quantifying #CDR at scale.

Enhanced rock weathering friends! 🪨 We're wrapping up our meta-analysis data-aggregation — is your paper in there? 📚 Check: tinyurl.com/ERWlit 📥 Add: tinyurl.com/ERWmorelit Really excited to get started on some exciting analyses soon! 🔬🌍

Here is another #Bluesky starter pack with scientists who were involved in the @ipcc.bsky.social #AR6 reports (with a likely WGI bias). Please let me know if I missed you! go.bsky.app/Erpq9Sq @valmasdel.bsky.social @edhawkins.org @glenpeters.bsky.social @lisaschipper.bsky.social

Another exciting year for enhanced rock weathering science. The number of pre-prints and other non-peer reviewed articles (blog posts, dissertations, etc.) is growing quickly, too. #ERW #CDR

Really enjoyed co-chairing this session yesterday. Loads of exciting science from how to quantify enhanced weathering in soils, how signals are transported into streams, and processes that may cause CO2 loss in rivers. Thanks to all presenters and attendees for the great session! :)

If you are at #AGU next week and work on enhanced rock weathering #ERW; the Carbon Removal Standard Initiative is organizing a community happy hour. See you there! :) lu.ma/60xhp274

EW Community Happy Hour @ AGU · Luma

Come hang out with enhanced weathering friends in town for AGU 2024! We'll meet at The Crown & Crow (about a 15 minute walk from convention center) for drinks,…

#AGU is coming up quickly! If you are in DC next week and care about enhanced rock weathering, here is a schedule of the most relevant sessions. Hope to see you there! For an emoji-based legend of the sessions, check out this linkedIn post: www.linkedin.com/posts/tjsuhr...

Can 100% recommend working with Tim Sweere, the whole team, and and @eth-eaps.bsky.social in general! :-)

#phd #jobalert Within a multidisciplinary research project, funded by @ethzurich.bsky.social, we seek a doctoral student to develop and evaluate new geochemical tracers for the quantification of carbon dioxide removal following enhanced rock weathering applications.

If you are looking to dive into the academic literature on enhanced rock weathering, I have shared my bibliography online: tinyurl.com/ERWlit Note the sheets on different sub topics. So many new publications recently... 😮 Will need to update this figure below soon.

Loads of new followers recently, so want introduce myself again. I investigate the potentials and limitations of using natural processes (like the weathering of rocks) to remove more CO2 from the atmosphere, and how we can quantify how well that actually works. That is also what I post about 🙃

I made a starter pack for people and organizations working in enhanced rock weathering #ERW! Kind of sad how short the list still is, let me know who I have missed. I tried to find the people I follow on Xitter - most are not here yet so convince your buddies come over, too! 🙃 go.bsky.app/NdcKXRS

Yesterday I had the pleasure to join a high school class in New York for an enhanced rock weathering 101 and to answer all things climate - the questions were fantastic & it was inspiring to see so much interest. Recommend 100%. Thanks @skypeascientist.bsky.social for organizing! #SkypeAScientist

Nature-based solutions are a game-changer: buffering shorelines from storms, shading cities and protecting them from flood, boosting crops with less water and fertilizer, and even improving human health. They're powerful, underused--and the future. Meet the experts leading this vital work ⬇️

hey bluesky, starting a carbon removal starter pack and i need all the help i can get, reply/DM to be added: go.bsky.app/NjxRfwo

Check out our new piece on potential environmental issues around enhanced weathering. Led by @charrlevy.bsky.social, we try to give clear monitoring and mitigation recommendations, rather than just a list of problems. The supplement has loads of useful stuff, too! doi.org/10.1021/acs....

Exciting Enhanced Weathering Postdoc opportunity at Yale University. If you are experienced in modeling Earth surface processes across soils, rivers, and oceans and want to improve our understanding of CO2 removal through EW (and OAE), this is your job: tinyurl.com/9dn7nrwc *please share*

Ah yeah that will surely reduce the amount of bullshit-bingo flying around. Fantastic.
