Study finds that enhanced weathering on farmlands could sequester up to 0.49 GtCO2/yr by 2070, with costs dropping to $100–150/tCO2 by 2050. Promising, but not a silver bullet—scaling challenges, equity concerns, monitoring & verification gaps remain & research on environmental impacts needed. 🧪🌏🌱

Alex Milde approached me last year with his idea how Ocean Alkalinity Enhancement via coastal enhanced weathering could be measured, reported and verified. He tested this idea in our labs at IMAS and the results are really promising. (preprint below) 🌊 www.authorea.com/doi/full/10....

Climate change is going to kill many marine species. Do we deploy marine CO₂ removal (mCDR) even though the deployments will negatively affect a small number of species?

How do we make sure the volunteer carbon market doesn't end up with the same conflict of interest as environmental impact assessment statements??? Company: I will pay you to say I am doing good things Assessor: Okay!

How does ocean alkalinity enhancement affect marine life? Researchers are investigating this question in a multi-week experiment led by GEOMAR in the Kiel Fjord as part of the international project Ocean Alk-Align. www.geomar.de/en/news/arti...

This could have been such great news... too bad these committees will get disbanded in January

New to BlueSky! Excited to mass follow everyone in the climate, mCDR, OAE space!!!
