Plants are the best option for capturing CO2

"They naturally extract CO2 from the air and use it as feed. The more CO2 plants absorb, the less CO2 remains trapped in the atmosphere."

As plants decompose, CO2
is released back to the air

"If left alone, plants are eaten by other organisms and releasing the carbon back to the carbon cycle within months."

Details in a ๐Ÿงตbelow โฌ‡๏ธ

"In the simulations, atmospheric CO2 is assumed to increase at a rate of 1% per year to four times its pre-industrial value and then decreases to the pre-industrial level at a rate of 0.5%, 1%, 2% per year, respectively."

Results show that "the annual mean state of surface ocean #carbonate chemistry fields including [H+] conc., pH & aragonite saturation state respond quickly to removal of atmospheric CO2. Yet, the change of seasonal cycle in CaCO3 chemistry lags behind the decline in atm CO2."

1๏ธโƒฃ possible under- and overestimation of the cost, potential, and availability (feasibility) of future CDR and
2๏ธโƒฃ the compound effect with uncertainty in climate sensitivity."
2/9
"All scenario results show that aggressive near-term mitigation is required for limiting warming to 1.5 ยฐC by 2100 for all levels of climate sensitivity, but that some amount of #CDR is likely required in the future even if climate sensitivity turns out to be extremely low."

๐ŸŒŠRecent study "presents the mass balances linked with #CarbonDioxideRemoval using seawater as both the source of reactants & as the reaction medium via electrolysis following the โ€œEquaticโ€ (formerly known as โ€œSeaChangeโ€) process."

๐ŸŒŠDetails in a ๐Ÿงต below โฌ‡๏ธ
1/12 Image
"The #Equatic process, broadly detailed in (pubs.acs.org/doi/full/10.10โ€ฆ), involves the application of an electric overpotential that splits H2O to form H+ & OHโ€“ ions, producing #acidity & #alkalinity, i.e., in addition to gaseous coproducts at the anode & cathode, respectively."
2/12 Image
"The #alkalinity that results, i.e., via the steady electrolytic pH pump results in the rapid precipitation of CaCO3, hydrated magnesium #carbonates (e.g., nesquehonite & hydromagnesite, etc.) or Mg(OH)2 depending on the carbonate ion-activity in solution."

"#CDR volumes
were further evaluated in terms of their relative and absolute contribution to total mitigation up until reaching
net-zero CO2, showing considerable variation across scenarios with a median relative contribution of around 20%."
