Olivine-based marine carbon dioxide removal field trial shows no adverse effects on the benthic community – CDRXIV Marine enhanced rock weathering (mERW) with olivine is a promising carbon dioxide removal (CDR) strategy, but its ecological impacts remain uncertain. In 2022, a first-of-its-kind mERW field trial was...

Questions about Lithos’ first ERW credit issuance – CarbonPlan We were surprised by the high removal rates claimed in a recent credit issuance to the ERW company Lithos. This post explains what questions the issuance raised for us, and what needs to change to get...

Lithos’s first enhanced weathering credits claim a surprisingly high amount of gross carbon removal that we think deserves scrutiny. We tried to figure out what could make these high numbers possible, but we were limited by the available data and left with more questions than answers.

Institutions submitting to CDRXIV can build up a substantial body of work over time — but there hasn’t been an easy way to share that work as a collection. Channels fix that, making an institution’s submissions viewable in one place. We’re launching this new feature with three founding channels.

I just resigned from NASA. It breaks my heart to leave, but I’ve become convinced the best path forward is to do the best science I can, and that can’t be here anymore. I’m still in love with the promise of those four magic letters. Ad astra per aspera, and remember: Earth is the only good planet.

NCAR is the backbone of Earth system science in the US and a global leader in open climate research. It directly supports our mission. Alongside a wide range of peers in the scientific research community, we submitted a letter to NSF strongly opposing any efforts to dismantle or restructure NCAR.

Today we’re launching Open Climate Risk, a fully open option for U.S. building-level climate risk data. It’s unique because it allows you to see not only risk scores, starting with wildfire, but also the complete underlying dataset, methods, and codebase. carbonplan.org/research/cli...

If you are #AMS2026, stop by our presentation tomorrow about the new work in climate services at @climatecentral.org (ams.confex.com/ams/106ANNUA...) - focusing on preserving critical climate data and improving the tools and communication of the local risks.

The need to consistently account for time in CDR – CarbonPlan We collaborated on a new preprint that establishes clearer language for talking about temporal lags in CDR, and shows how ignoring them can drive near-term warming.

Most carbon removal projects don’t pull CO₂ from the atmosphere instantly — there are temporal lags. We contributed to a new preprint showing why accounting for lags matters for both near-term warming and long-term temperature stabilization. 1/2

Consistent temporal accounting supports credible CDR use – CDRXIV Carbon dioxide removal (CDR) is increasingly used to support national targets and corporate net-zero commitments, yet the timing of atmospheric drawdown remains poorly represented in carbon accounting...

382: Silicates vs. Carbonates: How the 1996 IPCC Report Created Enhanced Rock Weathering Path Dependency—w/ Dr. Tyler Kukla, CarbonPlan Spotify video

Ross Kenyon and I talked about why enhanced weathering projects almost always use silicates, not carbonates. There's no single answer! But it was useful to look at the problem through the lens of path-dependence, and ask what it can teach us about CDR more broadly.

Wow. While we wait for the few remaining ballots to be counted, we feel like we have won this race. The recent drop put us nearly 1,400 votes ahead, just under the .5 percent threshold for a mandatory recount.

This gets at what I think is a fundamental problem with most well-intentioned, public minded SRM work — the governance requirements for ethical SRM would seem to be a subset of the governance requirements that would allow any plausible need for SRM to be avoided.

Scaling enhanced weathering in limed fields – CarbonPlan Both agricultural liming and enhanced weathering spread crushed rocks on fields and have the potential to remove carbon from the atmosphere. We explore how modifying liming for carbon removal works — ...

Agricultural liming helped create the infrastructure that enhanced weathering needs to scale up, but it also makes some enhanced weathering projects harder to support in the carbon market. We show why this tension exists and discuss some paths forward in our latest article.

Swapping carbonate for silicate in agricultural enhanced rock weathering – CDRXIV Enhanced rock weathering with crushed silicates is often considered as an alternative to agricultural liming for soil pH management and carbon dioxide removal. But swapping carbonates for silicates do...
