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! 🙃

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.

Aggregated monitoring of enhanced weathering on agricultural lands – CDRXIV
Terrestrial enhanced weathering (EW) on agricultural land is a promising carbon dioxide removal (CDR) pathway with high potential to scale. Enhanced weathering also has the potential to provide signif...

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! 🪨🌾

Enjoyed Isometric’s workshop yesterday and getting to discuss how to scale enhanced rock weathering responsibly and quantifying #CDR at scale.

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 🙃

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.

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!
