biological oceanography phd student at UH Mānoa. focused on ocean alkalinity enhancement, carbon, and coral. should we dump a bunch of rocks in the ocean?...hoping to know more soon

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.

A new approach for measurement, reporting, and verification of ocean alkalinity enhancement via coastal enhanced weathering Coastal Enhanced Weathering (CEW) is a marine Carbon Dioxide Removal (CDR) method that adds ground alkaline minerals to shallow regions of the ocean in order to increase seawater alkalinity, i.e., its...

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)

The trolly meme. A sketch showing a tram on tracks with a person standing beside it with a lever that switches tracks. On one track is a stylized figure labeled as "Marine organisms with mCDR" and on the other are five figures labeled "Marine organisms without mCDR".

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!

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