The Role of Marine CO2 Removal in Combating Climate Change [PDF]

Combating climate change requires not only rapid reduction of greenhouse gas emissions, but also removal of significant amounts of carbon dioxide (CO2) from the atmosphere.

The effect of carbonate mineral additions on biogeochemical conditions in surface sediments and benthic–pelagic exchange fluxes [PDF]

Biogeosciences
Coastal sediments are hotspots of biogeochemical processes that are impacting subsurface and overlying water conditions. Fluid composition in sediments is altered through the mineralization of organic matter which, under oxic conditions, further lowers ...

Ocean alkalinity enhancement in a coastal channel: simulating localised dispersion, carbon sequestration and ecosystem impact

Environmental Research Communications
Ocean Alkalinity Enhancement (OAE) is a proposed marine carbon dioxide removal (mCDR) method that has the potential to sequester CO _2 at the gigaton scale.

Biological thresholds for marine carbon dioxide removal (mCDR): the effect of changes in carbonate chemistry

Abstract. Marine carbon dioxide removal (mCDR) encompasses a variety of approaches to actively remove CO2 from the atmosphere, which, given current and projected emissions, is necessary to keep global average temperature increases to less than 2 °C. In addition to the removal of CO2 from the atmosphere, mCDR projects would have effects on the marine ...

The Pinatubo CO2 pause suggests a rapidly testable path to multi-Gt mCDR

Abstract After Pinatubo erupted in 1991, atmospheric CO2 levels stabilized during 1992–1993. Concentrations became ~ 2.25 ppm less than projected from contemporary emissions, corresponding to ~ 17.6 Gt of CO2 removed. CO2 did not return to projected levels in the following decades.

Ocean Alkalinity Enhancement: A Synthesis of Research on its Climate Mitigation Potential and International Governance Challenges [PDF]

Deploying carbon dioxide removal (CDR) technologies has been deemed necessary to complement drastic emissions reductions and limit global warming to well below 2°C compared to pre-industrial temperatures by the end of the century (IPCC, 2023).

Mechanochemical Deracemization: A Sustainable Approach to Enantiopurity [PDF]

International audienceWe introduce mechanochemical deracemization (MCDR) as a novel strategy for obtaining enantiopure compounds. This study demonstrates the successful transposition of six archetypical deracemization reactions from a solvent‐based to a ...
