In this cross-journal collection, we showcase articles that help with understanding how carbon dioxide removal can contribute to climate change mitigation.

Marine Carbon Dioxide Removal (mCDR) approaches are increasingly considered for climate change mitigation as a supplement to rapid emissions reduction. However, it is still unclear if mCDR approaches ...

New observations should prioritize easier-to-collect variables to rapidly increase temporal and spatial coverage of benthic data Multi-variable data sets need to be harmonized to provide comprehe...

Increased alkalinity significantly boosts growth rates of coccolithophores Gephyrocapsa huxleyi and Coccolithus braarudii Divergent responses between species arise as large C. braarudii rely on C...

Nature Reviews Earth & Environment - Natural CO2 removal is increasingly being claimed as anthropogenic climate mitigation. This misrepresentation is already prevalent for forests and coastal...

The paper analyzes the impact of omitting biophysical effects from carbon credits on climate mitigation. It shows that some Voluntary Carbon Market projects may result in net warming due to albedo whi...

This is a recording of the fourth webinar in the GGR Insights series, which presents the latest research and debates what is needed to enable the sustainable scale-up of greenhouse gas removal in the…

Abstract. The functioning and efficiency of ocean alkalinity enhancement (OAE) as a CO2 removal strategy is well investigated in model studies, but risks for the ecosystem are presently not considered...

The cycling of calcium carbonate (CaCO3) in the ocean is closely linked to seawater alkalinity and the regulation of atmospheric CO2. In the modern pelagic ocean, almost all CaCO3 is produced by three...

Tasmanian stakeholders require targeted knowledge on ocean alkalinity enhancement to develop informed views, particularly regarding feasibility, impacts, governance, and policy objectives, according t...

The idea that emissions can be offset through projects that claim to avoid releases or to remove carbon dioxide from the atmosphere is fatally flawed.

Abstract. Ocean alkalinity enhancement (OAE) aims to transfer carbon dioxide (CO2) from the atmosphere to the ocean by increasing the capacity of seawater to store CO2. The potential effects of OAE-in...

Ocean Alkalinity Enhancement (OAE) aims to mitigate climate change by increasing the chemical capacity of seawater to store anthropogenic CO2. OAE can be implemented through multiple pathways, each of...

Abstract. Ocean alkalinity enhancement is a promising carbon dioxide removal (CDR) strategy aimed at reducing atmospheric carbon dioxide (CO2) concentrations. To evaluate its effectiveness and potenti...

Upwelling generates a nutrient-rich “cold tongue” in the eastern equatorial Pacific Ocean (EEP), with impacts on global climate, oceanic biological productivity, and the carbon cycle. The cold tongue ...

Effectively scaling diverse marine carbon dioxide removal (mCDR) technologies from pilot-scale demonstrations to industrial-scale deployments requires a quan...

Diatom growth rates are determined by concentrations of CO2 and H+ across broad carbonate chemistry landscapes.

Marine carbon dioxide removal (mCDR) encompasses several ocean-based strategies to sequester atmospheric CO2 in the ocean to mitigate anthropogenic climate change. With a growing interest in chemical ...

Chemical weathering of silicate rocks occurs along a continuum from terrestrial to marine environments.

Increasing CO2 emissions have led to the development of CO2 removal strategies to counteract ocean acidification. Among these, ocean alkalinity enhancement techniques, particularly ocean liming, may ...

OPINION: “President Trump, a renowned climate change denier, has shown repeatedly that he has no use for scientific data that disproves his preconceived assumptions,” David Ho writes.

The ability of ocean models with depth coordinates to form Antarctic Dense Shelf Water (DSW) depends on their surface vertical resolution Deeper surface cells shift the direction of surface Ekman...

The landmark ruling means Australia must reduce emissions in line with the best science, and regulate the fossil fuel industry to prevent further harm.

Ocean alkalinity enhancement (OAE) is an emerging carbon dioxide CO2 removal approach for climate change mitigation and can be implemented with various alkaline materials that convert dissolved CO2 i...
