I missed to retweet this paper led by Charly about the potential of steel and iron slag for Ocean Alkalinity Enhancement #OAE. Some slag is quite effective, more than other minerals that can be found "in the wild".

Another recent paper by Charly that just got published showed the "Effects of grain size and seawater salinity on magnesium hydroxide dissolution and secondary calcium carbonate precipitation kinetics: implications for ocean alkalinity enhancement" bg.copernicus.org/articles/21/34…

Land carbon sinks are included in Nationally Determined Contributions (NDCs) but ocean sinks aren't. Should they be? No, for several reasons including additionally, equity, and difficulty of MRV (#CDR intervention, carbon uptake, and storage could be in different places).

Our new paper is out from nature! It shows that the contribution of preformed nutrients of Southern Ocean origin to low-latitude ocean production and export is more limited than previously thought. Please check it out!! nature.com/articles/s4158…

"Climate disinformation" is an elitist trap. Why? It centers the professional-managerial class in climate action — people who work with information — rather than people who build goods and grow stuff. jacobin.com/2024/08/climat…

Question to cdr.fyi: The database lists one of the biggest seller for durable CDR as "Not Disclosed" ( name and CDR method). Is that one singular seller or all the small sellers collectively? Surprising to see such a big volume without transparency provided by the seller.

The effect of rain on air-water gas exchange and CO₂ fluxes is a topic I started researching 30 years ago. I’m really pleased to see our latest paper — showing that rain enhances ocean CO₂ uptake — finally in print.
