#WeekendReading: Hu et al., trying a new approach to figure out past #alkalinity and #phosphate levels (at least diagenetically) using carbonate-associated phosphorus.

New work by @bach_lennart
The experiments show that anthropogenic #alkalinity can strongly reduce the generation of natural alkalinity, thereby reducing additionality. This is because the #anthropogenic alkalinity increases the calcium carbonate saturation state, which reduces the dissolution of calcium #carbonate from sand, a natural alkalinity source.

If you haven’t read it yet, also check out this incredibly comprehensive overview on #alkalinity in #CMIP6 models, and improvements from CMIP5 to CMIP6 by Planchat et al, with Laurent Bopp, Lester Kwiatkowski and many others.

New preprint from our group on #alkalinity biases in Earth System Models, attribution to processes, and implications for simulations of ocean alkalinity enhancement.

#Frontier just announced the second round of #carbon #dioxide #removal (#CDR) purchases by #Stripe and #Shopify. One of the companies is Captura, which is supposedly doing "Direct Ocean Capture."
Removing CO₂ from seawater is not CDR (you have to wait until that seawater equilibrates with atmospheric CO₂) so I don't know how this is better than Ocean #Alkalinity Enhancement.
But I don't care. I want to see them build this thing exactly as it's rendered here.
