If you're submitting an #AGU2025 abstract on #enhancedrockweathering biogeochemistry, microbiology, hydrology, modeling, MRV, public policy or social science, consider session B037, Enhanced Weathering for Carbon Dioxide Removal & Improved Soil and Agronomic Properties -due 7/30!

✨Paper #2 has just been published @weareagc.bsky.social ✨ And it is about hopanoids!! Thank you @climategordon.bsky.social for trusting a brand new journal with your research. AGC is 💎 open access: free to publish and free to read 🙌 Geochemists, come publish with us! journals.uu.se/AGC/article/...

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

Efficacy of seaweed-based carbon dioxide removal reduced by iron limitation and nutrient competition with phytoplankton – CDRXIV Carbon dioxide removal (CDR) is a crucial component of climate change mitigation strategies, and ocean afforestation via seaweed cultivation has been touted as a promising marine CDR (mCDR) approach d...

Introducing CDRXIV: A preprint server and data repository for CDR – CarbonPlan We are launching a new platform for openly sharing research results on carbon dioxide removal.

Introducing CDRXIV, a central hub for preprints and data on carbon dioxide removal (CDR). Our goal is to make it easier for CDR research to be shared and discovered by researchers in academia and industry. CDRXIV was built by @carbonplan.org. Read more about it here: carbonplan.org/blog/cdrxiv-...

Soil cation storage is a key control on the carbon removal dynamics of enhanced weathering – CDRXIV Significant interest and resources are currently being channeled into techniques for durable carbon dioxide removal (CDR) from Earth’s atmosphere. A particular class of these approaches — referred to ...

Direct measurement of carbon dioxide removal due to enhanced weathering – CDRXIV Enhanced weathering (EW) is a durable carbon removal strategy with clear pathways to produce significant global supply on a decadal scale. Despite increasing interest and investment in this process, t...

Cost of cooling: The value of reversible carbon storage in a zero-emissions world – CDRXIV Atmospheric carbon dioxide removal (CDR) is required to stabilize global temperature and can be achieved via ecosystem (e.g., soil and forest management) and geological (e.g., direct air capture) carb...

New accounting rules blur the line between decarbonization and carbon dioxide removal – CarbonPlan Isometric’s new protocol for wastewater alkalinity enhancement risks counting decarbonization as carbon dioxide removal. The rules could reshape how carbon removal is defined in other pathways, as wel...

A new wastewater alkalinity enhancement protocol can be used to issue CDR credits to activities that don’t increase the amount of carbon removed from the atmosphere. We wrote about how this breaks with other CDR protocols, and what it could mean moving forward.

A Framework for Integrating Spatial Uncertainty into Critical Zone Models: Application to Enhanced Weathering – CDRXIV Spatial heterogeneity introduces uncertainty when characterizing the Critical Zone, especially when sampling is sparse or requires repeated measurements at the same locations. Here, we layout a probab...

“What is CDR?” is the wrong question – CarbonPlan We summarize the ongoing debate around what “counts” as CDR, highlighting the trade-offs of each proposed definition. We suggest an alternative set of questions that can provide a more meaningful guid...

There’s an ongoing debate over what should “count” as CO₂ removal. In a new commentary with @hausfath.bsky.social, we break down key points of contention, proposed definitions, and why no definition offers a perfect path forward. (1/5)

Photosynthesis in Rivers as a Loss Pathway for ERW-Derived DIC and Alkalinity – CDRXIV As climate mitigation efforts lag, dependence on anthropogenic CO2 removal increases. Enhanced rock weathering (ERW) is a rapidly growing CO2 removal approach. In terrestrial ERW, crushed rocks are sp...

I'm going to be at the #AAAS conference in Boston for the next few days. A big part of why I'm there is to talk to folks about the open-source data tools we build at @carbonplan.org. We're working on databases for investigating offsets, a new preprint server for CDR research, and more. Say hello!

Limited impact on oysters in first-of-its-kind field trial of marine carbon dioxide removal (mCDR) strategy – CDRXIV Carbon dioxide removal (CDR) is a necessary component of limiting global warming to 2°C by 2100. Marine enhanced rock weathering (mERW) with minerals like olivine is a CDR strategy with the potential ...

The potential and cost of carbon dioxide removal using direct air capture with land-based wind and utility-scale photovoltaics – CDRXIV Rapid deployment of direct air capture and storage (DACS) is essential for meeting net-zero emission targets and requires accurate assessment of both the scale and cost of carbon dioxide removal. This...

We have so many bagels!

If you're at AGU and want to chat open science in CDR (or just want a bagel and coffee) stop by the @cdrxiv.org breakfast this morning! 8:30-9:30 in Pod 1 of the poster hall!

Carbon Dioxide Removal research needs a central, multidisciplinary hub. We’re building it at cdrxiv.org. Read and download others' work, explore CDR pathways and topics, and help the platform grow by submitting your CDR research!
