The concept for our greenhouse experiments is, turn it up to 11!
Measuring carbon dioxide removal (CDR) from enhanced weathering (EW) in the real world sounds straightforward: apply rock dust to fields, measure the results, done. The reality? Much messier.

Das COVID Infektionsgeschehen geht wohl erstmal weiter runter in DE: Bei der @dgina.bsky.social Notaufnahme Ampel sieht die Kurve ähnlich aus wie bei @rv-enigma.bsky.social's Datenauswertung, nur war der Peak in den ZNAs ca. 1 Woche später (ca. 22.10.).

When a company grows to 30 employees, everything suddenly changes. One day, you're a scrappy startup where everyone does everything. The next, you can't keep track of who's working on what.

COVID-Daten der @DGINA_eV Notaufnahmeampel zeigen ähnlich wie die Daten, die @rv_enigma unten aufbereitet hat, dass der Herbstpeak "durch" sein könnte. Es ergäbe sich ein ganz ähnlicher Verlauf wie im Vorjahr, aber auf niedrigerem Gesamtniveau. Ob sich der Trend bestätigt wissen wir in 1-2 Wochen.

The 4 stages for MRV of ERW look like this:
𝗦𝘁𝗮𝗴𝗲 𝟭: 𝗥𝗼𝗰𝗸 𝗣𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻 𝗮𝗻𝗱 𝗧𝗿𝗮𝗻𝘀𝗽𝗼𝗿𝘁 (𝗧𝗵𝗲 𝗦𝘁𝗮𝗿𝘁𝗶𝗻𝗴 𝗟𝗶𝗻𝗲):
Think of this as the preparation stage. We measure the emissions related to the production, transport and spreading of rock, which is fairly straightforward.

Buying durable carbon removal should take two minutes and a credit card, not weeks of emails.

Companies - like every other group of people doing something together - create their own cultures. Building cultures should be an intentional process. Don’t let it “just happen”.

There are basically three common options to measure enhanced weathering, where we redirect a small portion of the field’s carbon cycle into the leachate waters:

For enhanced weathering projects, there is very little alternative to a spreader if you want to bring rock dust onto farmland at the necessary rates of 10 to 40 tons per hectare.

The fundamental concept of enhanced weathering is to redirect a small part of the carbon cycle that happens naturally in a field in a way so that this carbon is redirected into the leachate waters in the form of bicarbonate.

What you see here is a pile of 29 tons of basalt dust, one truckload. To fight climate change, this rock can suck 9 tons of CO₂ from the ambient air when placed on the right soil at the right location.

@martin46er1.bsky.social‘s Modell ist m.E. notorisch verläßlich darin den Covid-Verlauf für die nächsten Wochen „gut genug“ vorherzusagen. Es zeigt einen dunkelziffer-korrigierten Peak um Inzidenz 1000 ca. Mitte November (grobe Verdopplung ab heute).
(1) Bis zum 28.10. bin ich in computerfreiem Urlaub. Als Vorbereitung für den Vergleich Modellvorhersage gegen Meldungen am 29.10. mein ‚Best Guess‘ von heute (Grafik 1-4). Die Kurven für R1± 0,05 sollen die Unsicherheit der Vorhersage andeuten (kein Konfidenzintervall!). /2

Carbon removal only works if storage is safe, permanent, and scalable.

If you scroll through climate headlines right now, it’s easy to feel discouraged.
BP scaling back its wind plans. Big banks pulling out of net-zero alliances. Google’s emissions go up instead of down. In the US, political winds are blowing hard against decarbonization efforts.

In our latest greenhouse experiment, we saw something striking:
Three pots with the same sandy soil, light, water, and temperature. But one pot flourished, while the others grew slower.
The difference? Particle size.
