A new update on our Ocean Alkalinity Enhancement study in Tasmania posted on bluesky.
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.
Article: About 6% of the total uptake of carbon dioxide by the ocean is due to rainfall @Geosciences_ENS @IPSL_outreach @CNRS_INSU @CNRSIdFSud @CNRS @laurent_bopp @_david_ho_ nature.com/articles/s4156…
"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.
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…
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).

Another recent paper by @C_Moras12 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…
I missed to retweet this paper led by @C_Moras12 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".
/!\ New research out (full text soon), where we looked at the suitability of iron and steel slag for #OAE. Surprisingly, steel slag had an unexpected high cumulative CO2 capture potential of 10-22 Gigatonnes by 2100! @FrontiersIn @bach_lennart @tcyronak frontiersin.org/articles/10.33…
