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! 🪨🌾

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.

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.

#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!

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 🙃

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!

I think there may be a feature for this, though I have not tested it yet; I don't have quite the same problem ;-).

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!

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!

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!

The field of enhanced rock weathering keeps growing: 2023 showed another ~50% increase in publications as well as some first patents...
