🔖🪨🚜🌧️🌊📉 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...

#Goldschmidt2025 science making the news: "Agricultural liming in the US is a large CO2 sink, say researchers" Press Release: buff.ly/pMIVR5L Talk by Suhrhoff et al. TODAY 14.30 session 05e: buff.ly/ZMGCbhL @eageo.bsky.social @geochemsoc.bsky.social @climatejesper.bsky.social

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

#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! :-)

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.

On Monday, Dr. Tom Reershemius defended his excellent dissertation - some super interesting findings to be submitted soon! It was an absolute pleasure to work together for the past year, excited to see what you will do next in #Newcastle - glad you are staying in #ERW science!

Our sensitivity analysis of soil-based approaches to quantify carbon dioxide removal from enhanced rock weathering is published. In short, they should be useful in most regions as long as you get your sampling protocols right & choose the right feedstock! doi.org/10.3389/fcli...

My PhD method chapter is finally published. Read if you are interested in how we can use lake sediments to reconstruct how silicate rock weathering has changed over the last glacial transitions. :) It is open acces! www.sciencedirect.com/science/arti...

Check out this data-driven piece on the efficacy of enhanced weathering! 🏔️carbon dioxide removal (CDR) estimates vary by 4 orders of magnitude. 🌱operational & methodological choices have a big impact on CDR. ... and much more in the article. Great collaboration with @carbonplan.org

The new abstract submission deadline for #ERW24 is now March 14th! This extension provides an excellent opportunity for those who have yet to submit their abstracts to present their work on enhanced rock weathering! All info on submission: www.erw24.com

Join us for ERW24, a free 1-day conference on enhanced rock weathering @Yale YCNCC on April 27th: www.erw24.com Abstract deadline March 1st. Hybrid format: online livestream, active participation in person only. Looking forward to your submissions! #ERW24 #ERW #CDR #MRV

The field of enhanced rock weathering keeps growing: 2023 showed another ~50% increase in publications as well as some first patents... lit list: tinyurl.com/ERWlit add missing lit: tinyurl.com/ERWmorelit Contact me if you want to help with the review project! :-)

Led by Tom Reershemius and Mike E. Kelland, our paper on using solid-based approaches to quantify carbon dioxide removal in enhanced rock weathering field trials is finally out! pubs.acs.org/doi/10.1021/... Not open access (😵‍💫), let me know if you need a copy! #ERW #MRV #CDR #TiCAT

A colleague and I are publishing a comment to a paper in a Wiley journal. The open access fee is 4330$. The paper is already open access. 4330$. For a comment. Grant does not cover publishing fees for a COMMENT. 4330$! What the actual fuck?!

If one sees the same post on twitter, Bluesky (, and Mastodon 😇), does one reply on 1 platform or all 3 such that different audiences see it? What are the cross-platform posting etiquettes? 🤔

Dear #ERW community, I am compiling a (hopefully) complete list of ERW literature. Am I missing any studies? Please share, add using the form, & reach out to collaborate! lit list: tinyurl.com/ERWlit form to add lit: tinyurl.com/ERWmorelit Result will be public too! 🥳

Hey all, I finally made it here! Follow me for enhanced rock weathering content and everything carbon dioxide removal. Trying to give (semi-) regular insights into my everyday science as well as takes on how rocks remove CO2 from the atmosphere. 🥳
