Net Zero: Actions for an Ocean-Climate Solution

It has long been understood that stabilizing the global climate requires human carbon emissions to converge toward net zero (Matthews and Caldeira, 2008). Analysis by the Intergovernmental Panel on Climate Change (IPCC) suggests delays in achieving net zero emissions, or a temperature increase of more than 1.5°C, will necessitate even stronger action: net negative emissions. A very large-scale opportunity for carbon sequestration would include yet unproven ocean-based carbon dioxide removal (CDR) technologies (Rogelj et al., 2018).
