Perspectives and challenges of marine carbon dioxide removal
Frontiers in ClimateThe Paris Agreement to limit global warming to well below 2°C requires drastic reductions in greenhouse gas emissions and the balancing of any remaining emissions by carbon dioxide removal (CDR). Due to uncertainties about the potential and durability of

Navigating Potential Hype and Opportunity in Governing Marine Carbon Removal
Frontiers in Climate, 2021 As the technical and political challenges of land-based carbon dioxide removal (CDR) approaches become more apparent, the oceans may be the new “blue” frontier for carbon drawdown strategies in climate governance.

Hugging the Shore: Tackling Marine Carbon Dioxide Removal as a Local Governance Problem
Frontiers in Climate, 2021 This Perspective explores the local governance of ocean-based carbon dioxide removal (CDR). Proposals to enhance the ability of oceans and marine ecosystems to absorb atmospheric CO2 are often discussed as examples of “geoengineering,” but this framing ...

Potential impacts of marine carbon dioxide removal on ocean oxygen [PDF]
Environmental Research LettersGlobal warming is a main cause for current ocean deoxygenation. A deployment of marine carbon dioxide removal (CDR) for mitigating global warming could therefore also be viewed as a measure for mitigating ocean deoxygenation if, and only if, the ...

Irreversibility of Marine Climate Change Impacts Under Carbon Dioxide Removal
Geophysical Research Letters, 2020 Abstract Artificial carbon dioxide removal (CDR) from the atmosphere has been proposed as a measure for mitigating climate change and restoring the climate system to a target state after exceedance (“overshoot”). This research investigates to what extent overshoot and subsequent recovery of a given cumulative CO

The Verification Challenge of Marine Carbon Dioxide Removal
Annual Review of Marine ScienceIt is increasingly obvious that, even when reaching net-zero emissions, removal of anthropogenic CO 2 from the atmosphere will be required. Some ocean-based removal technologies, while not proven for routine operation at scale, show promise. All of these rely on inducing a flux of CO

A holistic assessment framework for marine carbon dioxide removal options
Environmental Research LettersMarine carbon dioxide removal (mCDR) options could potentially play an important role in future CDR policy portfolios. They include, for example, ocean alkalinity enhancement, blue carbon projects such as mangrove cultivation, as well as sub-seabed ...

The Science, Engineering, and Validation of Marine Carbon Dioxide Removal and Storage
Annual Review of Marine ScienceScenarios to stabilize global climate and meet international climate agreements require rapid reductions in human carbon dioxide (CO 2 ) emissions, often augmented by substantial carbon dioxide removal (CDR) from the atmosphere. While some ocean-based removal techniques show potential promise
