Ocean iron fertilization may amplify pressures on marine biomass with only a limited climate benefit

Amidst a heightened focus on the need for both drastic and immediate emissions reductions and carbon dioxide removal to limit warming to 1.5°C (IPCC, 2022), attention is returning to ocean iron fertilization (OIF) as a means of marine carbon dioxide removal (mCDR). First discussed in the early 1990s by John Martin, the concept posits that […]

Addressing the problem of additionality in ocean alkalinity enhancement

The ultimate goal of marine carbon dioxide (CO2) removal (mCDR) is to sequester more atmospheric CO2 in the ocean than the ocean already does today. As such, any mCDR deployment must lead to quantifiably more CO2 sequestration in the ocean than would have happened without the deployment. This requirement is referred to as “additionality.” To […]
