On our way to Fürth, ready to bring carbon back to the geological cycle and reveal the secrets of silicate weathering MRV. #CDR Carbon Drawdown Initiative

What an exciting weekend setting up this EW experiment for #carbondioxideremoval with my #projectcarbdown colleagues! Dirk Paessler ralfonso.steffanides Dr. Maria-Elena Vorrath @mevorrath.bsky.social Mathilde Hagens Jens Hartmann @tahhco2 Jelle Bijma

POV: When your colleague takes down the drone with a single shot...

And we made it!! 🙌The largest #enhancedweathering greenhouse experiment 🧪 to quantify CDR has kicked off... Truly epic two days setting it up with all of you 💚 Dirk Paessler ralfonso.steffanides Dr. Maria-Elena Vorrath @mevorrath.bsky.social Jens Hartmann Mathilde Hagens Jelle Bijma @tahhco2 Patrick Niedermayer et al.

Unique experience setting up this ambitious #EW experiment to determine the rate of #CO2removal! Don't forget about the 🪱though, Patrick Niedermayer 😉 With Dirk Paessler ralfonso.steffanides Mathilde Hagens Dr. Maria-Elena Vorrath @mevorrath.bsky.social @tahhco2 Jens Hartmann Jelle Bijma and so many others 💚

Wondering what we were up to last weekend, building the biggest #EW greenhouse experiment to date?

The greenhouse experiment we set up a few weeks ago is greening and growing!

Anyone intrigued with the why and how of the unique greenhouse experiment Carbon Drawdown Initiative set up earlier this year, do read their latest blog article! Their results 🧪will be vital for scaling up enhanced rock weathering 🪨 to an effective CO2 removal method.

Great new video from Patrick Niedermayer presenting the why, what and how of the Project Carbdown greenhouse experiment, set up by Carbon Drawdown Initiative to speed up enhanced rock weathering and measure how much CO2 it removes over time! youtu.be/Kh4_9yOGyhs

Agree 💯 ...

Really excited about the presentations we could bring together on the Rock Weathering Day of the Climate Cleanup Double Nature Summit! Anyone wanting to know (more) about #cdr with rocks 🪨🪨on land 🌾or in the ocean 🌊 take a look 🔎 at the program climatecleanup.org/double-nature-…

We welcome submissions to the research topic: "Quantifying Carbon Removal by Negative Emissions Technologies" on Eric Zurrin in Climate, edited by Carlos Paulo, Connor Turvey, Ingrid Smet, Melissa Cook, James Campbell, @GeoloJess_ , and myself. frontiersin.org/research-topic…

Happy to announce I'll be speaking at the long-awaited Rock Weathering Day during the Double Nature Summit Title: #ProjectCarbdown – The theory and practice of measuring the speed of ERW in nature: our experiences with several MRV approaches climatecleanup.org/double-nature-…

Here is our detailed report about our attempts to measure the speed of enhanced rock weathering on croplands in four extensive field-experiments over more than two years. The traditional leachate- and EC/pH-based MRV approaches have not shown any signal (yet!). But by measuring

Exactly 💯

Our recent Project Carbdown paper triggered a lively email thread discussion - Dirk Paessler summarises the main points here!

On Wednesday Dirk Paessler will give a talk about our experiences with several MRV approaches at the Double Nature Summit. This is slide 0 of the presentation. Book your seat here (online is free)! eventbrite.nl/e/rock-weather…

EU policymakers must prioritise emissions reduction efforts in their post-2030 climate framework. Together with nearly 100 signatories we advocate for a firewall between carbon emissions, land sequestration and permanent removals in the EU carbonmarketwatch.org/publications/o… #3targets2040

Three years ago today we announced the start of #projectcarbdown where we try to measure the carbondioxide removal from the atmosphere by enhanced weathering on agriculturally used lands. We want to see "tons of CO2 captured&stored per hectare per year"!

We and our work are in Oxford this week at the 3rd Int conference on Negative CO2 Emissions. #negativeco2conference
